Using room temperature as the standard, then thermochromic dyes that are transparent at room temperature and colored when cooled are called Cold Activated thermochromic dyes.
There are no observations that a scientist can make to tell whether or not the hypothesis is correct. If I take my vitamins every day, then I will not feel tired.

A better explanation of the purpose of a hypothesis is that a hypothesis is a proposed solution to a problem. In the context of the scientific method, this description is somewhat correct. Start by finding some information about how and why water melts. It allows for predictions that will occur in new circumstances.

Use this printable scientific method worksheet to practice writing the perfect hypothesis. Practice Writing Hypotheses – Scientific Method Printables for Kids – School of Dragons.
A hypothesis is what you think the results of an investigation will be. Cold Activated Thermochromic (CAT) Stickers will be used to explain how to write a hypothesis. The hypothesis for many investigations is what the scientists hopes will happen.
This is a testable hypothesis - he has established variables, and by measuring the amount of oxygen in the water, eliminating other controlled variables, such as temperature, he can see if there is a correlation against the number of lice on the fish.
