Which physical property would be most important when choosing blocks to build a tall tower?
High strength to hold weight
Bright color to look nice
Smooth feel when touching
Small size for easy packing
A builder mixes sand with clay before shaping bricks. What is the main reason for combining these materials?
To add a shiny surface
To make the bricks lighter
To change the brick color

A student uses a magnet near a paper clip. What is most likely to happen?
The paper clip is pushed away
The paper clip is pulled toward the magnet
The paper clip floats upward
The paper clip melts into liquid
Which action is a push force you might use at recess?
Dropping sand from a bucket
Pushing a swing to move
Holding a block still
Pulling the wagon handle
You want to move a wagon toward you. Which force should you use?
Push the wagon away
Pull the wagon handle
Spin the wagon wheels
Use gravity to lift it
Which action is a pull that changes an object's motion?
Pulling a wagon handle
Pushing a swing forward
Tapping a table lightly
Kicking a ball softly
A ball rolls faster when you use more force. What simple change makes it roll faster?
Stand farther away
Use a smaller ball
Push the ball harder
Wait for the wind
You push a swing. Which effect best describes what happens to its motion?
It turns into a pull instead
It becomes heavier and slower
It speeds up and swings higher
It stops moving right away
A wagon is sitting still. How can you change its position using a pull?
Tap the side gently
Push down on the seat

Which picture shows an object that produces light energy?
A lamp glowing in a room
A drum being hit with sticks
A pot heating on a stove
A drum is played loudly at a parade. What type of energy is mainly produced?
Light energy from the drum
Sound energy from the drum
Thermal energy from the drum
Which is the best example of thermal energy in the kitchen?
Water boiling on a stove
Ice cubes in a freezer
A flashlight shining bright
You need to read in a dark room. Which item should you use, and why?
Use a pot because it makes heat
Use a drum because it makes sound
Use a lamp because it gives light
Look at the cars. Which statement is true about a fast-moving car’s mechanical energy?
It has lower mechanical energy than slow cars
It has higher mechanical energy than slow cars
Its mechanical energy stays exactly the same
Its mechanical energy disappears completely
A slow car speeds up. What happens to its mechanical energy as its speed increases?
Mechanical energy increases as speed increases
Mechanical energy changes randomly with speed
Mechanical energy decreases as speed increases
Mechanical energy never changes with speed
Two identical cars drive on a straight road. Car A moves slowly. Car B moves quickly. Which car has more mechanical energy, and why?
Car B, because faster speed means more energy
Neither, because speed and energy are unrelated
Car A, because color makes energy higher
Car A, because slower speed stores more energy
You push a toy car gently, then push the same car harder so it goes faster. Which choice best explains the energy difference?
The faster push gives the car more mechanical energy
Both pushes give the exact same mechanical energy
Energy only changes when cars change size
Energy only changes when cars change color
