Middle School Physical Science explores the fundamental concepts of matter, energy, and the interactions between them through engaging experiments and real-world applications.
In a chemical reaction, substances mix and change into new substances. Atoms rearrange, breaking old bonds and forming new ones.
Cooking, baking, and even rusting are all chemical reactions! When you bake a cake, heat causes the ingredients to react and form something new.
Chemical reactions power batteries, fuel cars, and even help plants grow through photosynthesis.
Mixing vinegar and baking soda produces bubbles of carbon dioxide gas.
Iron objects rust when they react with air and water.
Chemical reactions create new substances by rearranging atoms.
