Our kiddos love science and history, so we are usually a little "ahead" (for those who also follow TWTM) in those subjects (we are also "behind" in some things, like reading, but that's another blog post - lol!). According to The Well Trained Mind, Chemistry is to be studied in Third Grade. We, however, have explored Earth Science and Space (second grade science) as far as my children are currently interested, so we moved on to Chemistry. We're using 4 Usborne Books and one non-Usborne book. We read about Atoms and Molecules in the Children's Encyclopedia and also in the Usborne Science Encylcopedia (internet linked). My kiddos are enjoying See Inside Science, because the flaps allow them to see inside an atom and peek into the period table. 100 Science Experiments includes many fun and educational chemistry experiments. To fill in around the edges, we are also using Science Wizardry for Kids by Margaret Kenda and Phyllis S. Williams.
Today, we tested to answer the question, "Do molecules move?" We used water and a drop of food coloring to see if the water molecules move. When you drop the food coloring into the water and leave it alone for a while, you can come back to find that the food coloring is completely mixed with the water, proving that the molecules do indeed move, and stir the food coloring.
We're going to be testing to see if molecules move faster in hot water or cold water this week and next week, we're going to find out if there is empty space between water molecules and we're going to make a water molecule out of marshmallows - yummy & fun!
