OpenSciEd 7.1 Lesson 2 Quiz

When we examined the 5 different bath bombs (store-bought and homemade) in water, what were two repeated observations that we identified? (select 2 answer choices)

• Bubbles formed

• The bath bomb spun around in water

• The bath bomb broke apart

• There was a thick layer of foam

• The water turned pink

In our first 2 lessons, which scientific question did we investigate by planning and carrying out a controlled experiment?

• Where is the gas inside the bubbles coming from?

• How are bath bombs made?

• Why did the color of the water change?

• What will happen if I put a bath bomb in water?

When we conducted out Crushing Bath Bombs Investigation, which claim were we testing?

Hint: During this investigation we took the mass of a bath bomb in a ziploc bag before crushing, after crushing it, and after opening the bag.

• The gas is coming from inside the bath bomb, in the small spaces

• The gas is coming from the interaction of matter in the bath bomb, creating a new substance

• The didn't make a claim

One of the investigations we have conducted involved placing a bath bomb in a ziploc bag. The air was removed and the bag was sealed. The bath bombs were then crushed and the bag was observed to see if it inflated (filled) with gas bring released from the bath bombs. The images show the results of this experiment.

Question: Is the gas trapped inside of the bath bomb?

Make a claim that the data/evidence from the images supports.

Question: Is the gas trapped inside of the bath bomb?

Select two pieces of evidence that may be used to support a claim that answers the above question.

• In our crushing the bath bomb investigation, the bag inflated (filled with gas) when the bath bombs were crushed in the sealed bag.

• In our crushing the bath bomb investigation, the bag did NOT inflated (filled with gas) when the bath bombs were crushed in the sealed bag.

• The mass of the bath bombs stayed the same in the closed and open system.

• The mass of the bath bombs changed in the closed and open system

Question: Is the gas trapped inside of the bath bomb?

Select one reasoning statement that explains how the evidence prove a claim by using one or more key scientific ideas.

• This means that all the gas bubbles that appear when bath bombs touch water can't just be trapped in the bath bombs because gasses take up space and the gas would have filled the bag.

• This means the gas that forms when bath bombs are added to water is trapped inside the bath bombs because gasses are not matter and do not take up space.

• This means all the gas bubbles that appear when bath bombs touch water can't just be trapped in the bath bomb because the mass stayed the same and gas is not matter and does not have mass.

• This means gas that formed when bath bombs are added to water is trapped inside the bath bombs because gasses are not matter and do not have mass.
