A group of students conducts an experiment outside with a marble and a mound of dirt (to make a hill). They push the marble down the hill with different amounts of force. What should the students measure in this experiment to learn about how the mechanical energy of the marble is related to speed?
They should measure the amount of time the marble rolls each time.
They should measure the height of the hill.
They should measure the time it takes the marble to travel the same distance each time it is pushed downhill.
You are conducting an investigation to explore how pushing a toy car with different forces affects how fast a toy car moves on a flat surface. Which of the following is a key step in your investigation:
For a strong push use a different car than for a light push
Measure the mass of the car before conducting the investigation.
Use a strong force and a light force to push the car and measure how far each car goes
Push the car with one type of force and record the distance the car traveled.
Some cranes have the ability to pick up metal. Pick the correct statement which describes the type of force which allows the crane to pick up the metal against the force keeping the metal on the ground.
The crane uses magnetism to pull the metal up against the force of gravity.
The crane uses gravity to push the metal down against the force of magnetism.
The crane uses magnetism to push the metal down against the force of gravity.

Niuja and her friend Emma were eating popsicles outside on a hot sunny day. Which of the following statements represent what could happen to the popsicles if they aren't eaten quickly? Select TWO correct answers.
The popsicles could melt, changing from a liquid to a solid.
The popsicles could remain frozen as a solid.
The popsicles could melt, changing from a solid to a liquid.
The popsicles could remain frozen as a liquid.
The melted popsicles could evaporate, changing from a liquid to a gas.
When you fill up a glass with ice water during the summer time, moisture forms on the outside of the glass. What causes this moisture to form?
The warm air is coming into contact with the cold glass.
The water is leaking through the glass.
The water is rising out of the glass and falling onto the outside of the glass.
The water is coming from the sweat on the hand of the person drinking the water.
