MATTER
What are the 3 states of matter?
Solid, liquid, gas
What is needed to make a complete circuit in order to turn a light on and off?
Battery, wires, switch, light bulb
What is a force?
A push or a pull of an object
Name one way water can change the shape of land.
It can create canyons.
What is the water cycle?
The continuous movement of water within the Earth and atmosphere
How can you tell the difference between a solid and a liquid by using your senses?
I can see that a liquid takes the shape of its container, that it pours. I can see that a solid is hard and keeps its shape.
How does light behave when it hits a mirror?
It bounces off, causing a reflection.
What would happen if you pushed a heavy box and a light box with the same force?
The light box would be easier to push due to its lighter weight.
How does a glacier change Earth’s surface?
It creates a U shape valley
How does the sun help power the water cycle?
The sun heats water at the earth's surface causing it to evaporate and move up into the sky
What happens to the mass of water when it freezes into ice?
It stays the same.
Describe the type of surface that reflects light the best.
Smoothy and shiny
Describe how different materials affects the friction of a toy car.
The smoother the surface the less friction will be applied, the rougher the surface the more friction is applied
Compare erosion and weathering.
Weathering is the breaking down and erosion is the moving of the broken down material
Why is condensation important in the water cycle?
It is responsible for the formation of clouds.
Describe how a physical property like magnetism helps us identify different materials.
We can tell if something is magnetic or not. We can sometimes tell what type of metal it is based on if its magnetic or not.
What role does a conductor play in an electrical circuit?
They allow electric currents or heat to pass through more easily than others
What is gravity and what does it do?
An invisible force. Earth's gravity is what keeps you on the ground and what makes things fall.
What landform might be created by wind?
Sand dunes
What would happen if evaporation didn’t occur?
We would not have water to turn into condensation, in order to then become precipitation, and we would no longer have the water cycle
What is matter?
Matter is anything that has weight and takes up space. Anything you can see and touch is matter.
Explain how both reflection and refraction are involved when you look into water.
Reflection allows you to see an object that is above the water (like seeing yourself when looking at the water)
Refraction allows me to see a fish that may appear bigger than it really is due to the bending of light.
Design an experiment that could test how the height of a ramp affects the speed of a rolling ball.
The higher the ramp, the faster and farther the ball will roll. The lower the ramp, the slower and short the ball will roll.
Explain how wind, water, and ice work together to change landforms over time.
Wind moves different materials around, from place to place. Ice can pick up different materials and move them from place to place, as well as create U shaped valley. Water grinds down and weathers the rock it flows over
Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
