Oobleck

On Monday Kea conducted an oobleck experiement. We were testing if we could turn a solid into a liquid. The ingredients we used were corn starch, water, and food colouring. Some of our tests failed because we started with too much water then we added the corn starch making our experiement liquid-like instead of slimy!

Purple cabbage - Would you eat purple cabbage?

On Monday Kea conducted a red cabbage experiement. We tried to figure out what liquids have acid, base, or neutral PH levels. First, we tested vinegar the PH levels for vinegar changed to pink which tells us it is acidic (has a low PH level). We noticed when we tested the lemonade sprite the PH level colour was light pink and was acidic. When we mixed the acidic liquid and the base level liquid together they created a neutral colour on the PH scale.
