Example Questions
Example Question #1 : Pushes, Pulls, And Motion
An object can move on its own.
True
False
False
An object is not able to move on its own. An object must be pushed or pulled in order to move. A force has to be applied to it.
Example Question #2 : Pushes, Pulls, And Motion
Which would test how things react with a push or pull?
Playing hopscotch
Kicking a soccer ball
Reading a book
Kicking a soccer ball
If you were trying to test pushes and pulls kicking a soccer ball would be the best answer choice. Kicking is a push and it changes the speed and direction of the ball.
Example Question #1 : Physical Science
A class wants to investigate how to go down a slide the fastest. Which is the best plan to test this?
There is no way to test this
Have a friend push you on the slide at three different strengths
Go down the slide and guess which was fastest
Have a friend push you on the slide at three different strengths
Having a friend push you down the slide at different strengths and timing how long until you reach the bottom is a way to test how to get down a slide the fastest. Applying force with a push is a way to make things move faster.
Example Question #4 : Pushes, Pulls, And Motion
Which of these activities would test pulls?
Tug-of-War with friends
Playing video games
Bowling
Tug-of-War with friends
Playing Tug-of-War with friends is an example of testing pulls. Each team is pulling on the rope against each other to see who is the strongest. The team with the greatest force wins. Bowling would be an example of a push and there is limited movement in video games so it is not testing pushes or pulls.
Example Question #2 : Physical Science
What would happen if you pushed a toy car down a tall ramp versus a short ramp at the same strength?
The cars would both reach the end at the same time.
The car on the short ramp would reach the end faster than the car on the tall ramp.
The car on the tall ramp would reach the end faster than the car on the short ramp.
The car on the tall ramp would reach the end faster than the car on the short ramp.
If you were to push the toy cars with the same strength and the only difference was the height of the ramp then the car on the tall ramp would reach the end first. The taller the ramp the more force applied by the pull of gravity so the car would travel faster down the steep incline.
Example Question #6 : Pushes, Pulls, And Motion
If you are resting at the top of the slide, what gets you moving?
A push from a friend or yourself.
You move when the slide is ready.
The wind moves you.
A push from a friend or yourself.
When resting at the top of a slide you will not move until a force is applied. Most often it is a push from a friend or you push yourself off the top and begin moving. A push or a pull is required to get things moving.
Example Question #7 : Pushes, Pulls, And Motion
Which list of materials would be best used to test pulls?
A ramp and toy car
A hand and zipper
A book and bookmark
A hand and zipper
The materials best used for testing a pull or pulling would be a hand and a zipper. When getting dressed in the morning we pull up the zipper of our pants, shirt, or jackets. To test pulls we would need materials that allow us to pull. A ramp and toy car would most likely be testing pushes. A book and bookmark are great for reading but not testing pulls.
Example Question #3 : Physical Science
While fishing a boy notices it is hard to reel in the fish. Why is it hard to get a fish to the boat?
The fish is pulling against the boy.
The fish is pushing the boy.
The fish is moving with the boy.
The fish is pulling against the boy.
This boy many not realize it but he is planning and conducting his own investigation while he is fishing! He is asking a question and finding the answer. It is hard for him to reel the fish in because he and the fish are pulling against each other. The fish is swimming away from the boat and the boy is pulling the fish towards the boat.
Example Question #4 : Physical Science
Josh got his wheelbarrow stuck in the mud. How can he get it out?
It cannot be moved ever again
Pull or push it with a strong force
Wait for the rain to come and wash the mud away
Pull or push it with a strong force
The wheelbarrow is stuck deep in the mud. In order to move it a strong force in the form of a push or pull will need to be applied. Josh will have to overcome the force of the mud holding the wheels in place to break it loose.
Example Question #5 : Physical Science
What does it mean to plan and conduct investigations?
To come together, to hit or crash together
Think and do a project to answer questions
To be in contact with something, to feel something
Think and do a project to answer questions
Planning and conducting investigations can be done by anyone. If you have a question you want to be answered you can think of a project and carry it out. The world is full of questions and problems but investigating can help us solve them!
