We need more energy!
Can't stop the waves!
It's alive!
What on earth?
Anything goes!

Pietro is setting up an experiment. He wants to roll a ball down 2 different ramps. He wants to make sure the ball starts with different amounts of potential energy. How can he make sure this happens? How will he know which has more potential energy.
Pietro should make the ramp 2 different heights. The taller ramp will assure the ball has more potential energy.

What makes an object appear black? What makes an object appear white?
An object appears black if it absorbs all colors of light. An object appears white if it reflects all colors of light.

All energy in plants and animals ultimately comes from what?
The sun

You find 3 fossils in the ground in 3 different layers. What can you conclude about the fossil you found in the deepest layer?
It's the oldest.

What process has to take place before erosion can occur? Why?
Weathering must take place before erosion, because without weathering there would be no sediment to move.

A ball is thrown at 45 mph into a block of clay and makes a large dent in the clay. If the ball is thrown into the clay again at a lower speed, what will be different?
The ball will make a smaller dent.

Where do volcanoes and earthquakes occur?
Along plate boundaries. This is generally where land and water meet.

The city council wants to find a cheap solution to reduce the amount of trash that is collecting in the city's storm drains. The citizens propose 3 solutions. Which solution would be most effective?
Solution 1 would be most effective because even though solution 3 is cheaper, it will not reduce the amount of trash collecting in the drains.

The ball rolls down the ramp, hits the cup and makes a noise. The energy transfer was from (1)______ energy to (2)_____ energy. What would happen to the sound if the ramp was set higher? (3)
1) Kinetic
2) Sound
3) The sound would be louder.

The letters on the wall appear orange. Explain why they appear as orange and not any other color.
The orange light is what's reflected off of the letters. All other colors of light are being absorbed.

Humans poison the shrew. Which two populations will decrease?
Snakes and hawks

Bavly finds a megalodon tooth, but we're in Mount Juliet! What conclusion can Bavly draw?
Mount Juliet used to be underwater.

A student creates this chart to show renewable and non-renewable resources. There are two mistakes the student made. What are the two mistakes?
Coal should be labeled a non-renewable resource, and water should be labeled a renewable resource.

A musician uses his hand to strum his electric guitar, which is plugged into an amplifier. The amplifier then plays the music loudly. Name the 3 types of energy in the example and the order in which they transferred.
The musician's hand strumming the guitar used kinetic energy. The kinetic energy then became electrical energy which ran through the amplifier. The amplifier turned the electrical energy into sound energy.

What process is occurring in the picture? Explain how it works.
Refraction is occuring. The light passes through a medium, which bends the appearance.

If the leopard seals die off, which population(s) will increase? What will this increase cause?
Krill and actic cod will increase. This will cause a decrease in the tiny water plants.

What is occuring in this picture? Give a specific answer, then put the process in its correct category.
Tree root wedging is occuring! The roots are growing into the rock and breaking it apart. This is considered a form of weathering.

Zebra mussels attached themselves to ships from Europe and Asia and came to America. They invaded ecosystems in America and competed with organisms already there. What will the effect be on the ecosystem?
Native populations will start to die off/decrease because there is another species to compete with.

Gabe uses a rubber band as a slingshot by pulling it back and releasing it to shoot a small ball at the wall. The ball makes a sound as it hits the wall. Identify the energy types and any energy transfers that occurred.
Pulling back the rubber band creates potential energy. Releasing the rubber band to shoot the ball turns the potential energy into kinetic energy. When it hits the wall and makes a sound, kinetic energy transfers into sound energy.

Which wave has the highest volume? Which wave has the highest pitch?
Wave 3 has the highest volume because its amplitude is highest. Wave 2 has the highest pitch because its frequency is highest.

An invasive species is introduced where the X is. What will the effect be on the orcas? Will any population increase?
The orca population will decrease because it has new competition. The krill population will increase because the population of its predator will decrease.

How do you decide if a resource is renewable or non-renewable? Give an example of 2 non-renewable resources and 2 examples of renewable resources.
A resource is renewable if it can be regenerated and/or reused naturally. A resource is non-renewable if it can not be regenerated naturally fast enough for human use.
Examples of renewable resources include sunlight, wind and water. Examples of non-renewable resources include minerals and fossil fuel.

Some animals are known to protect coral reefs, while others can be harmful. In 2013 a population of starfish migrated to a coral reef in the Pacific Ocean. The chart shows the size of the coral reef after the starfish migrated. What can you conclude based on the chart?
Because the coral reef is getting smaller and smaller, you can conclude that the starfish are harmful to coral reefs.
