300
What is an Axis?
The imaginary line around which Earth rotates. It runs through Earth from the North Pole to the South Pole.
300
If an ice cube is left out in a room it will change from one state of matter to another.
Which is the correct order of State of Matter that the ice cube will go through?
Solid, liquid, and Gas
400
What is the difference between a conductor and an insulator?
A conductor allows heat or electric current to flow through easily, whereas, an insulator restricts or blocks the flow of heat or electric current.
400
If a balancing weight fell off of a wheel. What effect will it have on the car?
The car would not be able to travel in a straight line.
400
The diagram shows four light rays interacting with a material in different ways. Explain the diagram.
Refraction, absorption, continues in a straight line, reflection.
400
Where would the sun be positioned if the shadow was on the right side of the person? Explain.
The sun would be positioned on the left or opposite side of the person, because that is the direction light is being blocked.
400
A heterogeneous mixture is?
A mixture that keeps its physical properties while being combined.
500
If a person heats 250 ml of water in a cup and adds a tea bag, along with 10 mg of sugar. The tea bag steeps in the water for 15 minutes and then the cup is stirred to mix in the sugar.
What property will the sugar keep after dissolving in the tea?
- A Its grainy texture.
- B Its white appearance.
- C Its temperature.
- D Its sweetness.
D. Its sweetness.
500
When two people pull on a rope with unequal force in opposite directions, what is this situation called?
This is called unbalanced force.
500
What is the difference between concave and convex lenses?
Concave lens allows you to see a wider view making the image smaller, convex lens magnifies the image.
500
What causes day/night cycles, changing shadows, and the sun appearing to move across the sky?
Earth rotating on its axis.
500
What does the length of a shadow depend on?
The length of the shadow depends on the position of the sun.
