In class we have gone over the experiment we will conduct next class.
The experiment is designed to test 4 materials to see which one will cause a thermometer to heat up the most when they are all placed into the sunshine for 5 minutes. You can look in your journal to see the procedure and our data table that we will use.
Your homework is to make a prediction based on evidence and to explain why you think the experiment will turn out that way. This will be your Hypothesis.
To make your hypothesis you must:
Figure out which of the 4 materials you think will heat up the thermometer the MOST.
Figure out which material you think will heat up the thermometer the LEAST.
Explain your REASONING for both predictions using FACTS about light and other evidence.
Write your Hypothesis in the space we created in your journal and be ready to talk about it with your team in class next class before we run the trials. (You can use a google doc to write your hypothesis if you wish, then print it, cut it out and secure it in your journal on the page we set up. )
Your hypothesis will sound something like this:
"I think the thermometer wrapped in _________________ will heat up the most because _________________________." (Write a few sentences explaining your reasoning using all the facts we have learned about light.)
Second most will be the _______ because....
Third most will be the __________ because...
"I think the thermometer wrapped in __________________ will heat up the least because _________________________." (Write a few sentences explaining your reasoning again.)
A good hypothesis should include facts we have learned about light and the words reflect and transmit and absorb!
To help you remember how the experiment will work, here is a photo of the way that we will set up our thermometers when we conduct the trials next week. They will all sit in the shade until the trial starts. Then the 4 covered with materials will be moved to the sunshine for 5 minutes while the control thermometer stays out of the sun.
And just for a little mantis update.
Here is a link to the Video I took of a Mantis in the Outdoor Classroom on October 1st.
