🦎 GECKO GOSSIP
Why do Tokay geckos need information from their environment?
To find prey and avoid predators.
A toaster changes electrical energy into what form of energy?
Heat energy.
What is a fossil?
Preserved remains or traces of an organism that lived long ago.
What do dolphins use to communicate across distances?
Sound
A gecko cannot find its prey at night. What information is it missing?
Information from light.
What structure helps a gecko hear nearby predators?
Ears
What form of energy changes from what to what in a wind turbine?
Wind Energy → Electrical Energy
Which rock layer is older?
The bottom layer.
Two dolphin calls travel the same distance. One has a larger amplitude. Which call will sound louder?
The call with the larger amplitude.
A wind turbine has stopped spinning. What form of energy can no longer be produced?
Electrical energy.
Why is it difficult to see in a completely dark room?
There is no light entering your eyes.
What is the energy conversion that occurs in a flashlight?
Chemical Energy → Electrical Energy → Light Energy + Heat Energy
A canyon has a fast-moving river that has flowed for thousands of years. Would you expect more or less erosion? Explain
More erosion because the fast-moving water has a lot of energy and has been wearing away the rock for thousands of years.
A student says, “The water moves all the way from the mother dolphin to the calf.”
Is the student correct? Explain why or why not.
No. The water particles only move a little. The particles transfer energy to nearby particles.
A mother dolphin’s call has a larger amplitude than another dolphin’s call. Describe how the dolphin will hear the sound
Loud
Put the path of light to see
Light source → Object → Eyes.
A flashlight battery dies. Which form of energy is no longer available to power the flashlight?
Chemical energy
Two canyons have rivers. River A is faster and older than River B. Which river would likely expose more rock layers? Explain
River A, because faster-moving water and more time cause more erosion.
What causes sound energy to move through water?
Water particles collide and transfer energy
Two rivers flow through different canyons. River A is older, but River B moves much faster.
What additional information would scientists need before deciding which canyon experienced more erosion?
How long each river has been flowing and how fast the water moves.
Why did highway lights make it harder for Tokay geckos to survive?
Too much light made it difficult for them to form clear images.
Name 3 energy sources.
Any three of these: Sun, wind, water, fossil fuels, geothermal, biofuels, or nuclear
Why were more rock layers exposed in Desert Rocks Canyon?
The river was faster and had been flowing longer.
A dolphin calf hears two whistles. Both are equally loud, but one has a different pattern of wavelengths. How can the calf tell which whistle belongs to its mother?
The calf recognizes its mother’s signature whistle.
Scientists discover a fossil in a rock layer.
What evidence could the fossil provide about the area long ago?
What the environment was like in the past.
