Science Enquiry- Fair Testing

Last week we wrote our own scientific enquiry questions for example:-
If I change the type of washing liquid, what happens to the red stain on the cloth?
If I change the type of coke, what happens to the mentos?
We needed to carefully plan out our experiment and identify the variable and the constants.
Here are some pictures of our experiments. We will write up scientific reports and they will be in our portfolios for you to read.
