Basic Chemistry

Explore the exciting world of chemical reactions using safe, familiar materials! In this interactive kit, students observe and compare different types of chemical reactions—including color change, gas formation, temperature change, and precipitate formation—using simple household ingredients like baking soda, vinegar, and citric acid.

Each experiment is designed to be low-risk but high-impact, helping students understand evidence of a chemical change and the basics of how molecules interact. Includes all materials for 24 children working in pairs, plus printed instructions and step-by-step video support.

Time Commitment:
Two 45-minute class periods or one 1.5-hour session

Suggested Grades:
Grades 5–7

TEKS Alignment:

• 5.5(C): Identify changes that can occur in the physical properties of the ingredients of solutions

• 6.5(A): Identify evidence of chemical changes such as production of a gas, color change, or formation of a precipitate

• 6.5(C): Distinguish between physical and chemical changes in matter
