This document outlines two 5th grade science experiments about acids and bases, and classifying matter as solids, liquids, or gases. The acid and base experiment uses lemon juice, baking soda, and sugar to demonstrate a chemical reaction between an acid and base. The matter experiment asks students to sort pictures into the categories of solid, liquid, or gas based on their definitions and observe how the states change.

2. Standard: S.IP.E.1
Inquiry involves
generating questions,
conducting investigations
and developing solutions

3. OVERVIEW
• Acid and base
reactions
• Solids, liquids, and
gasses
• Temperature taking

4. EXPERIMENT
• FIZZY WATER
• Learn about chemical
reactions
• Acids and Bases
• Answer: WHY and HOW this
happened

5. INGREDIENTS
•2-3 sliced lemons
•½ teaspoon of baking
soda
•1 teaspoon of sugar
•Cup

6. GETTING STARTED
• Juice the sliced lemons into
glass
• Lemon juice is ACIDIC
Needs to react with BASE
• What material is our base?
• SUGAR? Or BAKING SODA?

7. Observe & Ask
Questions
•Add sugar to lemon juice.
-What happened? Why?
•Add baking soda, observe.
–What happened? Why?

8. CONCLUSION
•What questions do we
have?
•What did we observe?
•What is the base that
reacted with acid?

9. Scientific Investigations
Overview
• Identify solids, liquids, and
gases
• Put them into categories
• Know WHY they belong
there

10. SOLID LIQUID GAS
What do we ALREADY know?

11. •Definition of a solid?
•Definition of a
liquid?
•Definition of a gas?

12. PICTURE BANK
CRAYONS BALLOONS HOT CHOCOLATE SNOW
EVAPORATION SMOKE PAINT WIND

13. SOLID LIQUID GAS
Sort the objects!

14. CONCLUSION
•Investigated solids,
liquids, and gasses
•Assigned objects to
correct category
•Definitions

15. WRAP UP
•What we learned
•How we learned
•Why we learned
