Science Experiments and Concepts

This video tutorial guides viewers through five engaging at-home science experiments. It begins with making oobleck, a non-Newtonian fluid, followed by creating a glowing lava lamp using density principles. Next, it demonstrates how to make rainbow bubbles through an acid-base reaction. The video then explores static electricity with two demonstrations, and concludes with creating a tornado in a bottle using a vortex. Each experiment emphasizes safety and the importance of adult supervision for young scientists.

What is the main ingredient needed to make oobleck?

• Baking soda

• Vinegar

• Cornstarch

• Salt

Why should you avoid pouring oobleck down the drain?

• It will clog the drain

• It will dissolve

• It will evaporate

• It will change color

What causes the oil to rise to the top in the lava lamp experiment?

• Oil is heavier than salt

• Oil is lighter than salt

• Oil is denser than water

• Oil is less dense than water

What is used to make the lava lamp glow?

• Baking soda

• Phosphorescent powder

• Salt

• Vinegar

What reaction occurs when vinegar is added to baking soda in the rainbow bubbles experiment?

• Acid-base reaction

• Oxidation

• Neutralization

• Combustion

What is the purpose of using food coloring in the rainbow bubbles experiment?

• To increase the reaction speed

• To make it colorful

• To neutralize the acid

• To change the pH

How does a negatively charged PVC pipe affect water in the static electricity experiment?

• It freezes the water

• It evaporates the water

• It heats the water

• It bends the water

What causes the aluminum foil balls to dance in the static electricity experiment?

• Heat transfer

• Exchange of electrons

• Sound waves

• Magnetic fields

What is the key action needed to create a tornado in a bottle?

• Freeze the bottle

• Heat the bottle

• Spin the bottle

• Shake the bottle

What is used to connect the bottles in the tornado experiment?

• A rubber band

• A magnet

• A string

• A vortex connector
