Looking Back?
Looking beyond?
Big Question: Does the size of the bottle affect how much foam is created.

Research:
Elephant toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide. The potassium Iodide aids in removing the oxygen from the hydrogen peroxide. This happens very fast and creates a lot of bubbles. This experiment is going to create an Exothermic reaction this means that its also going to create heat.
Materials:
If swallowed hydrogen peroxide can cause severe stomach pain
Precautions
We will use safety goggles when doing the experiment to avoid splashes in the eyes.
Clean up:
We will put something underneath the experiment so that toothpaste can fall on it and it will be an easy efficient clean up
Documentation:
We will use our phones to pictures and videos.

Concentrating hydrogen peroxide is not to hard, we are just trying to get a higher peroxide to water ratio. This is can be achieved easily because hydrogen peroxide boils at 302F. To get a higher peroxide to water ratio we are just going to heat up enough to where a lot of the water evaporates an ideal temperature for this is around 212F.
Materials:
Flask
Hydrogen peroxide
Hot plate
Hazards:
High temperatures
boiling water
Concentrated Hydrogen peroxide, can be very corrosive especially to the eyes
it can coried you skin
Precautions:
Safety gloves and goggles, to protect against potential splashes from boiling water or hydrogen peroxide.
Clean Up:
Going to be easy in our clean up because its going to be poured in our experiment.
Documentation:
We will use our phones for pictures and videos.

Looking inward?
I would say we got desirable results the experiment turned out just as planed the only thing I was worried about was weather the concentrated hydrogen was going to work, mainly because i've never concentrated hydrogen or any element for that matter
looking Outward?
I worked with Marco and Meech, we've work with them a lot. There was no problems but I feel like I should start working with other people so that i'm not always working with the same people.
Looking Forward?
If I was going to do this experiment again would defiantly just add more of all the ingredients to make a bigger reaction. Other than doing the over just to have a bigger reaction I wouldn't do anything different I think everything turned aout pretty well. The people that were working sided by side with us also did really really well.
Take Aways?
I think the bigest take away I got from this experiment was learning how to cosentrate hydrogen paroxied because I found it fascinating the way that something smaller like the amount of hydrogen could be stronger
