yesterday my class and I made ice cream as part of an experiment about chemical engineering.
First we started with putting ice and salt in a bag, then put a bag full of milk cream and powdered sugar. closed the bag and put it in the bag of ice and salt then mix it by shaking up the bags. stop when the liquid becomes an ice cream like Consestentsee and enjoy.

PREDICTION / HYPOTHESIS
My Question is what effect does salt have on ice?
What we think will happen … we think that the salt will make the ice colder
MATERIALS
I will need …
1 small and 1 large plastic bag,
Sugar,
Ice,
Cream
METHOD / PROCEDURE
What I will do …
Add 8 cups of ice in a big plastic bag then add half a cup of salt together with the ice then perfectly seal the bag and shake it. Next get your smaller plastic bag and pour half a cup of milk inside it. Measure 1 cup of cream then also pour it in the same smaller bag with milk in it, then add 3 tsp of powdered sugar and add it in the small bag with a little bit of flavouring to it. Add the small bag inside the bigger one and wait. Always check on it after every 5 mins, and your done.
FAIR TESTING
Variables: (Can only change 1 Thing)
If I were to change something about what we did I would maybe add a bit more vanilla.
RESULTS
What happened?
Our ice cream was a bit runny, I think it should’ve sat in the ice a little longer for that thick ice cream effect.
REFLECTION
Next time I will change the flavour
