Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. Antarctica is a frozen land, so cold and icy that no trees can grow there. Yet scientists have
discovered fossils (remains preserved in rock) of ancient trees in Antarctica.
● What do you think this means? I think this means that Antarctica was once full of
trees ( Terrestrial Environment )and the dinosaurs or mammals that lived here
died and were preserved here , as the earth changed this environment changed to
nothing but a frozen land.
2. The Himalayas in central Asia are the tallest mountains in the world. But fossils of seashells
can be found high in these mountains, far from any ocean.
● How do you think they got there? I think they got there because the top of those
mountains were once the ocean floor and when the earth's plates moved and
pushed the mountain up marine life that lived there got trapped in the mountain.
Gizmo Warm-up
1. The Gizmo allows you to drag and rotate all the major landmasses on Earth.
● To drag a landmass, grab it in the middle
● To rotate a landmass, grab it near the edge
● Learn the names by opening the Tools menu and dragging the Help icon over the
landmasses.
● Mark where you live. Open the Tools menu and drag an arrow to your location.
2. Test your geography skills. Drag and rotate landmasses randomly until you make a big mess.
Then try to move them back to their original positions.
● When you have made the best map you can, open the Tools menu, select Screenshot,
and copy the image into a blank document. Label the image “Map 1.
