This year, we’re exploring CREATION with General Science (Apologia curriculum). Alas, as we began our studies learning about the history of science, we encountered a lot of hard-to-pronounce scientist names that I won’t require my students to remember, but we did pay closer attention to Democritus, Aristotle, Darwin, Newton and Einstein. With a few supplemental studies I’ve planned, the girls will be well-versed on the latter four by the end of this month.
Our lab experiments: atoms and density, atomic motion, and chemical reactions.
The girls learned that atoms are always in motion (but that they move faster in hotter substances than in colder substances – the blue food coloring in water experiment).
They also did an experiment that aimed at solidifying the existence of atoms and the concept of everything being made of atoms (a layered syrup/water/oil experiment where the liquids passed through one another). They also learned about density of objects (same experiment as previous but with added cork, grape, rock, and ice cube to compare the density of all).
Lastly, we did the classic cabbage juice, baking soda, and balloon experiment to show a chemical reaction (vinegar mixing with baking soda to form carbon dioxide, sodium acetate, and water; secondly, anthocyanin, the substance in the red cabbage, interacting with vinegar to form a pink color). Our balloon didn’t inflate as nicely on the first try, so we did this experiment twice!
