First, we talked about photosynthesis. We said how plants use it to make food, how it absorbs energy for light, and how it converts sugar to air. We also said how clorophyl and chloroplasts give plants green color, how the energy stored in sugar breaks it down, and how once oxygen is done it pairs in two. We also talked about some elements like H2O which means water, but more specifically 2 hydrogen and 1 oxygen. Also, Fe2 which is 2 irons, Si02 which is 1 sillicon and 2 oxygen, and Cl5 which is 5 chlorines. We also talked about how in order for it to be a particle it must be a capital letter. We made it a little more difficult by adding a number to the front of an element. For example, 3 H2O which I thought meant you multiply the amount of hydrogen and oxygen by the number in front of the element. Some other people thought it was 3 sets of H2O. It turns out we were both right because there are 6 hydrogen and 3 oxygen, but there are also 3 sets of H2O. To figure this out we made a model of an element with Legos. We made 3 to prove our theories. We watched this in 6th Grade and it really helped us learn in a fun way:http://www.youtube.com/watch?v=C1_uez5WX1o
