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!
