Landforms
The majority of Iowa's landforms were created by these.
Glaciers
The type of adaptation that includes things like migration, taking care of babies, and digging a burrow.
Behavioral adaptations
A machine that uses chain reactions to do a small task.
A Rube Goldberg Machine
The way that sound travels through the air.
Sound waves
A type of energy that can be used over and over again.
Renewable energy (or any example of renewable energy such as solar, wind, or water power.)
The area where 2/3 of Earth's volcanoes are located.
The ring of fire
Name at least 3 adaptations that a polar bear has to help it survive.
Camouflage, warm fur, large claws, a layer of fat to stay warm, large paws for walking on ice, strong sense of smell, ability to swim, etc.
A force that uses height energy and weight to make things fall to the ground.
Gravity
The name of the colored part of your eye.
Iris
The name for something we can use as a fuel that was created by plant and animal matter over millions of years.
Fossil fuels
A landform that is created by a piece of a glacier breaking off and getting run over and is shaped like a bowl.
Kettlehole
Name the 3 main reasons that animal species have to adapt.
to find food, to avoid predators, and to their environment changing
Energy that is stored up to be used later.
Potential energy
Explain why some animals see better in the dark than others.
They have larger eyes and pupils to let in extra light. Double points if you know that they have a reflective coating on their retina or that they have a different amount of rods/cones there.
A type of fuel that is common here in Iowa as a replacement for some of our gas. Hint: It's made with corn.
Ethanol
The name of the place where two tectonic plates meet.
A fault line
The name for something that an animal is born knowing, they do NOT need to be taught these things.
Instincts
Finish the COMPLETE statement: An object in motion...
stays in motion until a force acts on it.
The name of the things that send signals from your body parts to your brain and back.
Nerves
Circuit
The type of volcano that explodes.
Cone volcano
Explain why a tree would adapt to have deeper roots.
If the climate in an area was very dry for a long period of time, the trees may start to grow deeper roots to access water that is deeper in the ground.
Explain what happens in terms of energy as a pool ball hits all of the other pool balls.
The balls collide. The first ball passes most of its energy on to the other balls, but some energy is lost as sound waves and to friction and a little energy remains in the original pool ball.
Explain why some sounds are high pitched and others are low pitched.
The higher sounds vibrate more frequently than the lower pitched sounds.
Explain how heat energy can make a spinner go around.
heat energy always rises, so if we put a heat source underneath a spinner it will make the spinner go around.
