Evaluate responses using AI:

OFF

Answer explanation

It is important to choose a hard surface for the launch area because a hard surface provides a stable base for the rocket, ensuring it can launch properly. A soft surface might absorb some of the force and prevent the rocket from launching effectively.

What safety precautions should you take before launching the rocket? Explain why these precautions are necessary.

Evaluate responses using AI:

OFF

Answer explanation

• Before launching the rocket, you should ensure that you have a clear, empty space and keep observers well back from the launch site. These precautions are necessary because the rocket shoots up very quickly, and having a clear space prevents accidents or injuries from the rapidly moving rocket.

Describe what causes the rocket to launch into the air.

Evaluate responses using AI:

OFF

Answer explanation

The rocket launches into the air because of the chemical reaction between the baking soda and vinegar. When these substances mix, they produce carbon dioxide gas, which builds up pressure inside the bottle. When the pressure becomes too great, it forces the cork out of the bottle, propelling the rocket upward.
