Clam, Eel, and Red-bellied Piranha

We know a NEW gas was produced when we mixed two ingredients together in water because...

No gas was produced when we crushed one ingredient by itself in a closed bag.

New gases can't be made by mixing ingredients.

Science always works like that.

Which bath bomb ingredient do you would produce the least amount of bubbles?

Both would produce the same amount of bubbles.

Neither would produce any bubbles.

Where are the ingredients that occur the most located on a Nutrition facts label?

Closter to the top (at the beginning)

Closer to the bottom (at the end)

What happened when the bath bomb ingredients were mixed one at a time with water?

Nothing. No NEW gases were created.

Bubbles were formed at the bottom of the container.

The temperature of the mixture increased and began to boil.

The water and ingredients disappeared.

Which of the substances below has the EXACT SAME properties?

None. They all have unique properties.

What happens when we add a bathbomb to water?

We increased matter in the reaction

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

Gas was created as a result of a chemical reaction

Gas was trapped inside the bathbomb

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

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

Nitrogen, Argon, or Carbon Dioxide

Nitrogen, Carbon Dioxide, or Oxygen

Characteristics that can be measured or observed about a substance

All listed on the periodic table of elements

Elements that are flammable and less dense than air
