What are two decisions we make everyday in everyday life where we use scientific knowledge?

Planting plants. (knowing the the amount of water and sunlight needed in order for it to grow properly)

Cooking.(the chemical and physical change in the objects and ingredients used)

Boiling water. (knowing the right temperature for water to be fully boiled)

Etc.

Basically everything you do requires math and science in it in general.

For example, Breathing. You are going through the entire respiratory system every single day and minute and of course even while your sleeping.
