5th grade explaining their bath bomb engineering project to third grade

Why do you think the dye made it crumble?

# data[].attributes.body
We love that you didn't give up and you kept trying to make it better and more solid.

Mrs. Ballard's class presenting their bath bombs to Mrs. Harris' class

# data[].attributes.body
We heard one group say they used a few drops of lavender. Did you have other options for the smell?

# data[].attributes.body
Connection: I noticed in the hallway that they used fractions and measurement for their project.

# data[].attributes.body
Wonder: Why did you need to use citric acid?

# data[].attributes.body
Connection: They used more than 2 materials like we had to.

# data[].attributes.body
Notice: They focused on energy transfers like dissolving the bath bombs.

# data[].attributes.body
Wonder: Did you have to rebuild the bath bomb from scratch every time?

# data[].attributes.body
Notice: The 5th graders did a great job presenting and not reading their slides!

"We noticed that you used measurement to come up with your recipe for the bath bombs. Right now, we are measuring with liquid volume and mass."

-Elyse

# data[].attributes.body
"We just learned about fractions, and I saw fractions in your hallway. Also, we saw fractions on your recipes."

-Carter

# data[].attributes.body
"We had to try multiple times for our energy transfer in our set boxes to work. I saw that you also had to try a few times for your bath bombs to work."

-Macie

# data[].attributes.body
Why are some of the bath bombs different shapes? I noticed that some were half circles and some were full circles.

# data[].attributes.body
"I noticed that a lot of the bath bombs were purple. Was there a reason for this? Is there another reason other than the fact that it's eye catching?"

-Declan and Juliet

# data[].attributes.body
I noticed that you used milliliters in your recipe. We are also learning about liters and milliliters in math.

# data[].attributes.body
I noticed there were a lot of different colors, names, scents, and ingredients. Why did that happen? Why were some based on movies?

# data[].attributes.body
How did you persevere when things were tough?

# data[].attributes.body
"What is the mass of your bath bomb? Does that change from test to test? Does the mass impact the dissolving?"

-Elly and Canaan

# data[].attributes.body
I noticed that you were using fractions, and we learned fractions in math too!

# data[].attributes.body
"I noticed that perseverance is our character trait for the month and you did a lot of perseverance."

-Easton

# data[].attributes.body
Why did it have to bubble? What caused the fizz?

# data[].attributes.body
"I can connect this project to my project because both had a criteria and constraints."

-Anaya

# data[].attributes.body
Did you have to measure in milliliters? or could you have measured with a different unit?

# data[].attributes.body
"How did you solve your challenges like figuring out which materials would work?"

-Caseton

# data[].attributes.body
Connection: In math, we talked about mass and volume. We heard you use milliliters!

# data[].attributes.body
"What was the main problem for all of the groups and why was that the main problem?"

-Lucy

# data[].attributes.body
"I noticed that each bath bomb had different names. What helped you name the bath bomb? Was it the color?"

-Evie

# data[].attributes.body
Connection: At home, I put vinegar and baking soda in a bag. It fizzed, like your bath bombs. At the beginning of the year, we talked about irreversible changes.

# data[].attributes.body
"What was the most used material for the bath bomb and why?"

-Hazel

# data[].attributes.body
Why did one test of the bath bomb look so flat when I saw it?

# data[].attributes.body
Where did you get the scent?

# data[].attributes.body
"I noticed that you had to research chemical reactions. We had to research circuits, magnets, and simple machines. Circuits can cause different reactions if they are open or closed."

-Jonah and Lucy

# data[].attributes.body
Connection: I noticed they used line plots like we do!

# data[].attributes.body
I notice we both learned about energy

# data[].attributes.body
I noticed prices on some papers in the hall. Are they on sale?

# data[].attributes.body
What did you do to fix the problem of the bath bombs breaking?

# data[].attributes.body
I noticed in the hallway that you guys were learning about fractions like us! I was able to add the fraction problems you guys had in the hall.

# data[].attributes.body
Why were some of the bath bombs broken in the containers?

# data[].attributes.body
Why are you guys studying WWII?

# data[].attributes.body
How did you change the colors?

# data[].attributes.body
How did you choose your names for your companies?

# data[].attributes.body
What gave you the ideas for the different colors and scents?

# data[].attributes.body
Was there a minimum number of ingredients that you had to have?

# data[].attributes.body
How did you determine the ingredients were safe for skin?

# data[].attributes.body
Did you have a certain number of essential oils to choose from? If so, what were the scents that you could choose?

# data[].attributes.body
I noticed that when you tested the bath bomb, it started bubbling. What is the ingredient that caused that reaction?

# data[].attributes.body
I liked how you all had your own different recipes. None were the same, the measurements were different, and it seemed more unique that way!

# data[].attributes.body
How did you determine how much of each ingredient that you needed?

# data[].attributes.body
I noticed that when you tested the bath bomb, it bubbled/fizzed up and looked like it was about to overflow, but it stopped at the top. This was interesting!

# data[].attributes.body
When you tested the two bath bombs in class, one of them worked and one of them didn't. What were the differences in the ingredients that made one work and one not work?

# data[].attributes.body
"How did you put scent in it?"

# data[].attributes.body
What were some of the problems that you faced?

# data[].attributes.body
How did you know how much of the ingredients to put in?

# data[].attributes.body
How did you know when the mold was full?

# data[].attributes.body
Can I buy one of your bath bombs?
