You have a bowl filled with marble and a ping pong ball. What is the best way to see which one is denser than the other?
Place a magnet next to the ping pong balls and marbles.
Dump them in the water to see if one will sink or float.
Place them on a triple beam balance.
Count the number of marbles versus the number of ping pong balls.

4th-grade students are playing with a rubber airplane. They want to know how the number of winds of the rubber band affects the airplane moves. What would they change in their investigation?
Number of winds on the rubber band
Number of airplanes
The distance it travels
The length of the airplane
Students are investigating with a toy car on a carpeted floor and the cemented floor and compared the distance the toy car traveled, what force are they trying to investigate?
Gravity
Friction
Magnetism
All of the above
Students are taking turns in dropping the parachutes that they made. Both students claim that their parachutes landed faster than the other. What can they do to investigate which one landed faster?
Ask another friend to watch and see which one landed the fastest.
Measure the width of the parachute.
Change the length of the rope of the parachute.
Ask one friend to time each parachute as they land on the ground and see which one has the shortest time.
How will you know which magnet is the strongest?
Place the magnet in water and see if it floats.
Use a ruler to measure the length of the magnet.
Use a balance to measure the mass of the magnet.
Count how many paper clips each type of magnet picks up.
Sara wants to see if a new brand of hair dye lasts longer than the brand she currently uses. She puts the new hair dye on the left side of her head and the old brand on the right side. After 2 weeks, she observed which side of her head has more gray hair showing. What is the independent variable?
left side of her head
the types of hair dye
the amount of time
her grey hair

Students want to know if mass affects the time it takes an object to hit the ground when it is dropped. Which investigation will best answer this question?
Drop a feather, a ping pong ball, and a small piece of paper from the same height and record the time it takes each to hit the ground.

Students are investigating how far the toy car will travel from a ramp. What should students do to make sure that the data they collected is accurate?
Change the type of toy car for every test.
Roll the toy car down the ramp few more times.
Change the height of the ramp every time they roll the toy car.
Change the surface of the ramp every time they roll the toy car.
From the data above, what is the best conclusion?
As the distance of the magnet increases the force of attraction increases.
As the distance of the magnet decreases the force increases.
As the distance of the magnet decreases, the force of attraction decreases.
The distance has nothing to do with the force of attraction.
Students investigated on letting a cube slide over a sandpaper and over a regular cardboard. Which scientific question could the students be investigating?
What is the effect of the height of the ramp to the cube?
What is the effect of friction between the cube and the surfaces?
What is the effect of gravity to the cube?
Is it a pushing or a pulling force?
What happens when south poles of magnets are placed together?
The magnets will attract.
The magnets will repel.
The magnets will not move.
The magnets will lose its power.
Students had the set-up shown above. Which of the following questions could the students investigating on?
Which type of ball will roll the fastest?
What kind of ramp will make the ball roll farther?
How does the weight of the ball affect the distance it will travel?
How does the height of the ramp affect how far the ball will travel?
