Mix glue with baking soda and add contact lens solution gradually.
-
Knead until you get slime consistency.
Learning Outcome: Demonstrates polymers and chemical reactions—great kids science ideas.
8. Invisible Ink
A simple spy-themed experiment.
Materials: Lemon juice, cotton swab, and paper.
Steps:
-
Write a message with lemon juice using a cotton swab.
-
Heat the paper gently to reveal the hidden message.
Learning Outcome: Shows chemical reactions triggered by heat.
9. Paper Chromatography
Teach color separation in an engaging way.
Materials: Filter paper, markers, water, and a glass.
Steps:
-
Draw a dot with markers on the paper.
-
Dip the paper’s end in water and watch colors separate.
Learning Outcome: Explains chromatography and pigments in inks.
10. Homemade Compass
Combine magnetism and geography.
Materials: Needle, magnet, cork, and water.
Steps:
-
Magnetize the needle by rubbing it with a magnet.
-
Place the needle on a cork floating in water.
Learning Outcome: Teaches basic principles of magnetism and navigation.
