Acid Rain PSA

What is a PSA? A PSA is a public service announcement that aims to raise awareness about a specific issue. You will be creating a 2-3 minute video on acid rain.

Your video should include:

1. A clear explanation of acid rain. What is it? How is it formed? What are the two most common compounds that contribute to acid rain?

2. How does acid rain affect plants, animals, aquatic ecosystems, the soil, man-made objects and people?

3. You can pick a specific country and focus on the effects of acid rain in Switzerland, Russia, Germany, the U.S. etc.

4. What can people to do minimize acid rain?

The plan for working on the video:
Wednesday Dec. 1
Go to the computer lab to research additional information and work on your script.

Friday Dec. 3
Turn in script for proof reading, rehearse, create props/posters for the video

Homework over the weekend:
Practice! Practice! Practice!

Monday Dec 6
We will video tape the PSA's in class. These video's will be posted on the blog.

Creativity Counts! This will serve as your test on acid rain, so make sure your information is correct. Everyone must participate in the project.

How will you be graded for this project?
Your grade on this project is divided into three parts:
1. Content: Is the content correct? Did you answer the questions above? (60%)

2. Team Work: How well did you work with your teammates? Did each person contribute? You will be grading each other on participation. (20%)

3. Creativity: Is your project a snooze-fest or does it inspire people to make a change? (20%)

Make sure you proof read your work and write neatly! This assignment counts for two lab grades.

Friday, November 12, 2010

Seeing Molecules & Temperature Investigation 2

Today we started a more formal experiment to collect data and continue to see the effect that temperature has on the movement of molecules.

On Monday we will finish the experiment.

On Friday, November 19th you will have a test on The Air Unit. Things that will be on your test include: the composition of the atmosphere, layers of the atmosphere, what causes wind, how temperature affects the movement of molecules, how temperature is related to hurricanes, as well as some science skills like graphing and interpreting data.

Thursday, November 11, 2010

Seeing Molecules & Temperature Investigation

On Wednesday we did a practice investigation to see how temperature affects the movement of molecules. Students had some good suggestions on ways to reduce the sources of error in the experiment. Taking what we learned, we'll do the experiment on Friday.

Homework: none.

Tuesday, November 9, 2010

Seeing Currents

We know that hot air rises, but we can't really see that happen. Today we were able to see that water functions like air, in that hot water rises and cool water sinks.

Homework: You will have an open notes quiz tomorrow.

First read the paragraphs below about convection. Then read about atmospheric circulation here.


The one way that heat is transferred from one place to another is convection. Convection takes place when heated molecules move from one place to another, taking the heat with them. Convection is common in both the atmosphere, as well as in the oceans.

Heated air in our atmosphere expands, becoming less dense. Because it is less dense, it rises upward. Cooler air rushes in to replace the air that lifted up. As warm air rises, and cool are falls, a giant circular pattern is created. Eventually the warmer air cools, and begins to fall again. [1]

"Convection" has several, related meanings in weather....but it always involves rising air. It usually refers to "moist convection", where the excess water vapor in rising air parcels condenses to form a cloud. The heat released through this condensation can help to sustain the convection by warming the air further and making it rise still higher, which causes more water vapor to condense, so the process feeds on itself. Convection can also be dry, as occurs on a sunny day over the desert. The sun warms the ground, and convective air currents help to remove the excess heat from the surface. Dry convection also occurs during the day even when clouds are forming...you just can't see it.
Interesting facts:
MAKING THE EARTH LIVEABLE: Convection (both dry and moist) help to make the Earth liveable by removing excess heat from the surface, and transporting it high into the atmosphere. It has been calculated that, without convection, the average surface air temperature on the earth would be about 125 deg. F, rather than the current 59 deg. F. [2]

Homework part 2: Watch the video clip below about the atmosphere from National Geographic.

Monday, November 1, 2010

New Unit: The Air

What is the sky? What is the air? What is the atmosphere? Are these the same things? Why do we have different climates in different parts of the world? Wait, what is a climate?

These are all questions we'll answer over the next few weeks. Today we learned how elements and compounds relate to the air. For homework: Read and take notes on the layers of the atmosphere. Click the picture to link to your homework assignment. You will have a reading quiz on this information on Tuesday.


Please bring the lid of a shoe box to class tomorrow for a mini-project.

Monday, October 25, 2010

Test Today

Today students took a test on the water unit. When we return from academic travel we will be starting our third unit of the year: The Air.

Friday, October 22, 2010

Test Review

Today we reviewed what we have learned over the past 14 classes during our water unit. On Monday you will have a test.

Make sure to review all your notes and handouts from class.

Wednesday, October 20, 2010

Candle Lab

Today each student observed a candle (don't worry, we were outside). We were able to see physical and chemical changes and practice making observations.

Homework: if you didn't finish the analysis questions in class, please finish these for homework. On Friday we will be wrapping up our water unit and reviewing for the test on Monday.

Monday, October 18, 2010

Boiling Point Web Lab

We started off today by comparing chemical and physical changes, the we did the web lab below.
Click the picture below to go to the activity.
Originally your homework was going to be to find information on the boiling point of an element, but after searching for almost two hours, I haven't been able to find anything interesting and grade-level appropriate other than websites that would have you copy down just a number for a boiling and melting point.

So, we have a change of plans.

Tomorrow we will do the candle lab and organize your notebook for your notebook check on Monday.

Homework: make sure you bring your notebook to class and if your notebook is a mess, dig through your room and find all of your science papers; BRING THESE TO CLASS!.

States of Matter & Phase Change

Today we used a BrainPop video clip to help us learn about the states of matter for water and phase change. The video talked about physical changes, but what about chemical changes?
Homework: Read about the differences between chemical and physical changes here. Take notes for a reading quiz tomorrow.

If you have a computer or iPad, please bring it to class tomorrow.

Friday, October 15, 2010

Club Significance



Today we started to learn about significant figures and how to identify them in our calculations.

For homework you need to do problems 1-10 on the front of the worksheet. You do not need to do the problems on the back, we will do those in class on Monday.

Thursday, October 14, 2010

Density of Water

On Wednesday we used graduated cylinders and a triple beam balance to determine with density of water (which is 1g/mL).

To look at density we attempted the soda can demo. What we should have seen was this:
Instead we "defied" the laws of density :) Maybe Swiss Coke is different from American Coke...

Tomorrow we will be going back over the data you have collected in the density experiments to determine the how to accurately present our data using significant figures.

Tuesday, October 12, 2010

Revisiting the Density Cubes

Today students had another opportunity to practice measuring and finding the density of objects. We review the formula, the importance of labels and compared the mass found using a triple beam balance and an electronic balance.

Homework: None. However there was a bonus homework question proposed by Gianromano: "Why is the formula for density mass divided by volume and not volume divided by mass?" Find out the answer and get a bonus point on your homework.

Monday, October 11, 2010

Lab Check Up!

Today students had a Lab Check Up! to see how much they really understand about using lab equipment to solve a problem. Below was this week's problem:

Over the weekend there was a mix up in the lab involving various materials. The cubes you are about to receive were all labeled neatly in containers. However, something happened and now we don’t know what the cubes are made out of anymore. The science department needs your help finding the density of these substances to determine what they are. After identifying the substances, we identified which samples are elements and which samples are compounds. But what does all of this have to do with water? Many different elements and compounds contribute to water pollution.

Homework: Click the picture below and it will take you to a website. Click on the following areas, read about them and take notes. You will use your notes for a mini open notes quiz tomorrow.

You should read about AND take notes on: Chemical, Nutrients and Suspended Matter.

Friday, October 8, 2010

Finding Mass Using a Triple Beam Balance

Today we did an activity called Mix and Match Mass to learn how to use a triple beam balance. After making predictions about the mass of the items they have been working with over the past week, students found the actual mass of the items.
Homework: First, use the handout below from the Day 1 of Volume by Displacement. Use the volume you found for four of your objects and use the mass you found from today's activity, to find the density of each object.

For Example: If you found the volume of Rock #22 to be 30mL and the mass of Rock #22 to be 10g, the density would be 0.33g/mL.

Wednesday, October 6, 2010

Volume by Water Displacement 2

Today we continued practicing measurement with water displacement.

Homework: You can either watch the video clip below AND take notes.... OR... go to this website and take notes. Your choice. Make sure you include the formula for finding density and the definition of density.


Tuesday, October 5, 2010

Volume by Water Displacement

Today we did a lab to see how the volume of an irregular object can be found using the water displacement method. After attempting to find the volume of various irregularly shaped objects using a ruler, students found the volume by water displacement.
Tomorrow we will evaluate our results and see if our data is accurate. There is no homework tonight.

Monday, October 4, 2010

Measuring Liquid Volume

We started class today by asking the question, which referred to the lab on Friday:

Not everyone had the same number of drops fit on their coin. If all of the coins were about the same size, how is this possible? How can we make the measurements the same?

Today students learned about various tools that scientists use to take accurate measurements. Students did a worksheet to help them practice reading various volumes of liquid. Tomorrow we will be doing a wet lab using displacement to help us determine the volume of irregularly shaped objects.
Homework: Complete the worksheet for finding the volume of a regularly shaped solid. Note: you can absolutely use a calculator for this assignment.

Friday, October 1, 2010

Sinkin' Lincoln Lab

Today students had an open notes quiz to see how well they were paying attention to what their peers taught them in class on Wednesday.

After the quiz we did the Sinkin' Lincoln Lab to examine surface tension. We also reviewed how to take an average and find the max./min. of a set of data.
Homework: (due Monday): Finish the questions on the back of the lab sheet.

Wednesday, September 29, 2010

Water Jigsaw

Today students shared what they had learned from going to their assigned websites. Instead of sharing in groups like we did with the soil jigsaw, a representative from each group came up to the board and taught the entire class.

Just to make sure that students were listening to their peers, we will have a 10 minute open notes quiz on Friday based on what we talked about in class on Wednesday. So...

Make sure you bring your notebook to class on Friday!

Tuesday, September 28, 2010

Properties of Water

Today we started to talk about the properties of water. Tonight for homework you will click on your name and take notes from your specific website. Tomorrow in class we will do a jigsaw activity just like we did for the soil unit.

When you take notes you can write in bullet points or complete sentences. If you type your notes, you MUST bring a paper copy to class. You can also use diagrams to help enhance your notes.

Some of these are note traditional readings, some of these websites are interactive or video clips.

Test Review

Today we spent time reviewing for your test on Friday. We learned about different types of questions and why some test questions are easier than others.
For your first test, 60-65% of the questions will be at the knowledge level. Our goal as the year progresses is to have less questions at the knowledge/remember level and more questions at the higher levels.

Tuesday, September 21, 2010

Eewww! That smells gross!

Today we had a lot of success with our soil bacteria cultures. We also learned about the basic parts of a bacterium as well as how quickly one bacteria can turn into 5,000 billion billion bacteria. You can watch the video clip we watched in class below the picture.



We also continued to practice how to identify controls and variables in an experiment. You have no written homework for tonight, other than to study for your test on Friday. Tomorrow we will be reviewing for your test.

Monday, September 20, 2010

Soil Bacteria and Controls and Variables

Today we talked about what it means to have a controlled experiment and set up our own lab to culture soil bacteria. Over the next few days, we should have agar plates that resemble the one below.After setting up our experiment, we used the Simpsons to practice identifying controls and variables in experiments.

Homework: finish the back of the Simpsons controls and variables worksheet. Note: These two problems are harder than the three on the front of the worksheet. Just try your best. You can do it!

Here's a math hint for the Krusty the Clown problem:
50% (or half of 30) =15
So... if the new itching power is advertised to last for 50% longer that the original itching powder (which lasts 30 minutes), the new itching powder lasts for 45 minutes, then the advertisement is correct.

Food Webs

Today we learned about food webs and how energy, nutrients and elements flow through living things. Homework: Read about Bacteria, Fungi and actinomycetes here. For each topic: Bacteria, Fungi and Actinomycetes write down three things you learned and two questions you have. This means you should have a total of 15 complete sentences. You must write in your own words. If you choose type this assignment, you must bring a printed copy to class.

Tuesday, September 14, 2010

Berlese Funnels and Dichotomous Keys

Today we went outside and you collected samples for your Berleses funnels. Hopefully on Friday we'll have some organisms to look at :)

We also learned about Dichotomous Keys and created our own for the class. For homework, due on Friday, you will need to make a dichotomous key for the organisms pictured below. There are lots of different ways to make a key, so it's OK if yours is different from someone else's key. Please work on your own to complete this assignment. You do not need to print out the pictures, just write your key in your notebook and bring it to class on Friday.

Element Sharing and Experimental Design

Today students shared the elements that they researched over the weekend. We are now going to move forward from the inorganic (elements/nonliving) to the organic (living) things found in the soil.

Tomorrow we will be making Berlese funnels and begin talking about how we will classify what we find.
The illustration above shows how it works: a funnel (E) contains the soil (D), and a heat source (F) such as an electric lamp (G) heats the litter. Animals escaping from the dehydration of the soil descend through a filter into a preservative liquid (A) in a receptacle (B).

Homework None:

Friday, September 10, 2010

Interpreting Nutrition Labels

First a quick reminder about your homework:

Read the post below this one (or click here) for details about your Element Trading Card Assignment.

Today one of your peers asked, "But what do nutrition labels have to do with soil?! Why are we doing this?" You might have been thinking the same thing. We need elements, compounds, mixtures and molecules to function. Today we learned about some of these such as Vitamins A & C, Iron, Calcium, fat, sugar and protein. Next week we will learn about what elements, compounds, mixtures and molecules (ECMM) are in the soil. What ECMM do the organisms that live in the soil need? Are these the same ECMM that we need? Stay tuned!


We also looked at the molecular structure of fats, sugars and proteins, it turns out they a combination of H, C, O and sometimes N. What makes each molecule special? It's shape!

Thursday, September 9, 2010

The Periodic Table

Today you reviewed the differences between elements, molecules and compounds and were introduced to the periodic table. We will be using the periodic table throughout the next several weeks.

Tomorrow in class you will each be given an element to make an 'element trading card.' These 'cards' will be due on Monday September 13th. The guidelines for the assignment are below. You can click on the picture to make it larger. You will also receive a copy of this paper tomorrow and your assigned element.


Lastly, you must cite your sources. On the back of your trading card list all of the websites, books or other materials you used to gather your information. For example:

If your element were Zinc and you used this website, you would need to write the following information:

Name of the website, url, date you visited the website.
Chemical Elements.com - Zinc (Zn) http://www.chemicalelements.com/elements/zn.html, visited on (whatever day you visited the website).

Not sure where to find the name of a website or the URL? Click the picture below.

Tuesday, September 7, 2010

Elements, Compounds & Mixtures

Today in class we talked about elements, compounds and mixtures. Students were given a guided notes sheet to use during a powerpoint. We played a short game to practice categorizing elements, compounds and mixtures.

Homework:
1. Answer the question on the last page of your worksheets from today, "what elements do you think are found in the soil."

2. Using the periodic table in your student planner, identify the key elements 1-6 on the last page of the worksheet from today.

Soil Jigsaw

Today in class we used the websites students looked at for homework last night to do a jigsaw activity. Students shared the information they learned about soil in small groups.


Homework: Complete the soil question sheet. No computers needed for this assignment.

Monday, September 6, 2010

What sound does a raisin make?

Today you were asked a very strange question: What sound does a raisin make? Many discoveries in science have been because people asked very strange questions. They looked at ordinary things were curious, HOW does the thing work, WHY does it work that way, WHAT makes it behave like that?


In our first unit, The Soil, we will be looking at something that many of us consider very ordinary.

Your first homework assignment is to find your name below and click on the link. On a sheet of paper

1. Write your name
2. The url for the website (a url is the address, for example: www.tasis.ch is a url)
3. Read the information on the webpage.
4. Write down three things you learned about soil. Be specific and please use complete sentences.
5. Two things you have questions about from the reading. These might be things you don't understand or things you want to learn more about.

This is assignment should take you no more than 20 minutes.

Syllabus


We will be starting our year learning about the soil. This is where you might be thinking: Huh? What? Ugh, really? Before you try and say that soil might be the most boring thing you’ve ever heard of, I ask you to think about this:


Since [the beginning of] time humans and other animals have been dying of all manner of diseases and then buried in the soil, yet not a single major disease is transmitted by it." (Hillel 1991, p. 24).


So, what is it about the soil that makes it so unique? Both the air and the water can spread disease, why doesn't the soil spread disease?

Honesty: Being honest with yourself, is there something you don't understand? Ask. Being honest about your class and homework. Did you work on your own or did you copy from someone else?

Homework: Homework will be assigned almost every night and be incorporated into the following day’s class. A late assignment defeats the purpose of completing it. Therefore, late homework will not be accepted and will be graded as a zero. Assignments include, but are not limited to: worksheets; problem sets; readings; preparing for a discussion/presentation etc.

Make-up Work: You are responsible for obtaining missed assignments. If you know in advance you will be missing class for co-curriculars, an appointment etc. you should notify me in advance at least 2 days in advance.

Late Work Policy: As previously stated, late homework is not accepted. Late projects will be accepted up to three calendar days after the due date. However, each day that the project is late, 10% of the grade will be lost. After the third day the project will no longer be accepted.

Extensions: Extensions will not be given except in the event of extenuating circumstances, so plan your time wisely.

Attendance: Attendance is mandatory at all class meetings. You are expected to arrive on time in be in your seat with your homework and your notebook on your desk. A pattern of tardiness will be regarded as not meeting the expectations of the class and will affect your effort grade.

Class participation: In order to make the most progress in this class you will need to participate actively. Participating in class not only means sharing your ideas but also coming prepared and on time.

Notebook: Must be divided into two sections and have a table of contents:

You must keep a detailed table of contents for your notebook.

Class Rules:

· BE ON TIME!

· BE PREPARED! Bring the textbook, your notebook, highlighters and pens/pencils each day.

· BE PRESENT! Both in mind and body. Showing up for class doesn’t mean much if you are daydreaming.

· If you have an unexcused absence from class on the day of a test or quiz you will receive a zero.

· As soon as you need extra help, come find me. Don’t wait!

· NO eating or chewing gum in class. You may bring water.
