How does panting make a dog feel cooler?
Hypothesis: An idea about what the answer to the problem is. Encourage kids to make guesses. Also use the term “hypothesis.” Tell the kids that since they are scientists they need to use big science words. By repeatedly using the term, the kids will quickly know what to do, which is to Make Fun Guesses!!! Of course you cannot test every hypothesis, but the important thing is to encourage the kids to participate. Experiment: A way to find out if your hypothesis (guess) is correct. Tell the kids that you found a book that has a fun experiment about why dogs pant. Explain that when a dog pants his warm breath causes the saliva on his tongue to evaporate. Again, point out that is a word that scientists use. Ask the kids to say the word, “Evaporate.” Give examples of evaporating, such as water in mud puddles disappearing. Does the water really disappear? No, but it does change into a gas that cannot be seen. Say, “Let’s make some liquid evaporate from our skin to see if our skin feels coole
