Refer to Chapter 7: Lesson 1, in the Science text below to read more about sources of energy and energy transformations (conversions). You can also preview Lesson 2, renewable and nonrenewable resources, which we will be focusing on next week!

We watched a Bill Nye video on energy transformations (or conversions)! What types of transformations does Bill Nye talk about in the video? Record four different types of energy transformations you observed in the video. Explain what is happening, draw a picture and label each transformation. (The link keeps changing, search Youtube to find the video!)
Your forearm and foot are the same length. Try measuring the length of your forearm (from the crook of your elbow to your wrist) and compare it with the length of your foot. You'll be surprised that they are the same length. Did the data we collected in class today prove this fact? Why or why not? How could we have collected more accurate data?

Today in class we analysed a graph that represented the size of the hole in the ozone layer above Antarctica. What trends do you notice in the graph below? Many of you wondered whether or not the ozone can repair itself over time. What does the graph suggest? I have linked a website below that gives some information about the ozone depletion. What can you find out about the ozone depletion?
Malaysia is famous for its reptile population. I can sometimes see monitor lizards on the edge of the pond. I often see them standing still. Have you ever wondered how quickly they can move? Well, the spiny-tailed iguana, native to Mexico and Central America, is able to move 9m/s. Visit the link below to solve (or finish solving) the spiny-tailed lizard math problem. Can you create your own problem about a reptile found in Malaysia?

Here is another poem about homework, written by Shel Silverstein. How does it differ from the poem below? What form of energy do you think is being used to run the homework machine? Would like like to invent a homework machine? If so,what kind of energy would make it work? What would it look like? What could it do?
In school, we talked about the energy used by things on our campus. Are there even more forms of energy? What do we call the type of energy used when we move our arm? Watch the Study Jams video below to find out more information about the energy we use in our daily lives.
