Forces of Nature

See how an earthquake can reshape the face of our planet. Explore the page on Eathquakes from the National Geographic and create a foldable explaining: Where do earthquakes occure? What causes earthquakes?, and types of faults. In the last part, trigger an earthquake and find where is the worst place to build a house.

Simple Machines

Hey! What about exploring your house to find simple machines? Click on the gears to go to Edheads simple machines to learn about the 6 simple machines and how they can be used to build compound machines. Use the information on the website to do a chart with the different types of simple machines, function, and examples. Do a poster showing what you learned about simple machines.

You can click on the lever to find definitions on the simple machines
You can click on the pulleys to find examples of simple machines

Rock Cycle

Review very carefully the information on the link. Do a graphic organizer including the 3 types of rocks. Explain in detail how each rock was formed. Explain the role of erosion in rock formation, and what cementation is. Finally, write in your own words why it is called "Rock Cycle".

Manipulating Variables

To make this human cannonball successful, you need to manipulate different variables. You'll need to be very organized to record all the changes in your journal. Describe in detail 3 different situations where you made the performer land safely. Explain how did you manipulate the variables. Was it usefull to manipulate one variable at a time? What strategy did you follow?

How Fast are Sound Waves?

Have you ever wonder how fast is the sound? Click on the link, and find the yellow activity rectangle on the upper left corner. Click on "How far away is it?", and do the activity. You may need to use your math to figure out where does the sound travels the faster. Is it on the air, or in the water? How can you explain the results? Record everything in your Science Journal.

Natural Resources

It's time to know which natural resources are renewable, nonrenewable, and inexhaustible. Go to this link, and click on the yellow activity rectangle where says Resource ID. As you explore the game, write a chart listing all the resources in the right column. Find the commonalities among them, and try to define what renewable, nonrenewable, and inexhaustible resources are. Don't forget to take notes on your journal!

Stellaluna Adaptations and Food Chains

Listen to the story of Stellaluna by Janell Cannon, and write a page summary in your Science notebook. Using a Venn Diagram, compare the different adaptations between the birds and the bats. Explain how Stellaluna adapted to her new life. Write and illustrate at least 2 food chains that happened in the book.
