Answer:

Potential,Kinetic

Explanation:

When an object is higher up on a surface it has more Gravitational Potential Energy whilst when an object is lower down but moving fast it has more kinetic energy. So when the object moves down the ramp energy is transferred from the gravitational potential energy store to the kinetic energy store.

What is the best description of how heat is transferred from deep in the earth to the surface?
a. Conduction brings hot magma up through the mantle toward the crust, where it cools and sinks.
b. Convection brings hot magma up through the mantle toward the crust, where it cools and sinks.
c. Convection brings hot magma up from the core to the crust, where it cools and sinks.

Use the information and data from the tests to make a recommendation for which blanket the government should choose. In your response include scientific reasoning to support your recommendation.
Reasoning: Explain using scientific principles and connect the test results to the criteria and constraints.

Which is a limitation of comparative investigations?

They give results that are usually not repeatable by other scientists.
They might show variable relationships that are not actually cause and effect.
They can usually only be conducted in labs instead of in natural environments.
They are usually inexpensive, but they do not provide new information.

When an Alka-Seltzer® tablet is put in water, there is a chemical change because there are bubbles produced. The Alka-Seltzer® tablet slowly disappears over time. What would speed up the chemical change?

Adding more water would cause the chemical change to speed up.
Changing the color of the tablet would cause the chemical change to speed up.
Decreasing the temperature of the water would cause the chemical change to speed up.
Increasing the temperature of the water would cause the chemical change to speed up.

Physical Models Activity

You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:

✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
✔ Models must be created by you, not something selected from an online or outside source.
✔ Submit a presentation, picture, video, or screenshot of your model.
✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.

Conservation of Mass
