What happens when we add a bathbomb to water?

• The temperature changes

• Everything turns solid

• Bubbles and Fizz

• We increased matter in the reaction

Where did the gas from the bath bomb mixture come from?

• Gas was trapped inside the bathbomb

• Gas was created as a result of a chemical reaction

When we crushed the bath bombs in a bag,

• The bag did NOT inflate, so no gas was trapped

• The bag inflated, so the gas was released

• We started a chemical reaction

• The bath bomb mixed with water

True of false: We discovered one ingredient alone does not cause the chemical reaction.

• True

• False

The ingredients needed in the bath bomb to create a chemical reaction are:

• Corn Starch and Olive Oil

• Citric Acid and Corn Starch

• Baking Soda and Citric Acid

• Baking soda and vinegar

To find out what gases could be coming from the bath bomb, we tested what TWO properties?

• Flammability and Density

• Heat energy and Magnetism

• Electricity and Magnetism

• Density and Electricity

Tags

NGSS.MS-PS1-2

Gases that will rise up in a room full of air are:

• More dense than air

• Less dense than air

• The same density as air

After testing properties, we discovered the possible gases produced in the bath bomb are:

• Hydrogen, Oxygen, or helium

• Helium, Nitrogen, or Argon

• Nitrogen, Carbon Dioxide, or Oxygen

• Nitrogen, Argon, or Carbon Dioxide

Properties are:

• All listed on the periodic table of elements

• Characteristics that can be measured or observed about a substance

• Elements that are flammable and less dense than air

• The way we measure the amount of gas in a system

A system that we can seal so that nothing can enter or exit is a:

• Closed System

• Open System
