Physical Science Riddles

100

I'm solid, liquid, and gas, and I'm essential for life to last. What am I? 

Water

200

I have no color, but I can make a rainbow. I have no weight, but I can fill a room. What am I? 

Light 

300

I'm always moving but never alive, I push and pull but cannot thrive. What am I? 

Force 

400

   I'm found in the ground, in the air, and in flames. I'm in every breath you take, though you don't see my name. What am I? 

Oxygen

500

I can break, but I'm not alive. I can't bend, but I'm not alive. What am I?

A wave

Properties of Matter Riddles

100

I can change my state when you add or take away heat. Solid, liquid, or gas, what am I?

Matter 

200

I take the shape of my container, but I'm not a gas. I can flow and be poured. What am I?

A liquid

300

I'm spread far apart and move around fast. You can't see me, but I can fill any space. What state of matter and I?

Gas 

400

I'm the amount of matter in an object, no matter the size. What property am I?

Mass 

500

You use me to measure how heavy something feels. But I'm not the same on the Moon as I am on Earth. What am I?

Weight 

Law of Motion Riddles

100

I'm fast when I start, slow when I end. I'm a measure of how far you've been. What am I?

Speed

200

I keep moving forward, but I never change direction. What am I?

Momentum

300

I'm an object's resistance to change its state of motion. What am I?

Inertia 

400

I'm the path of a moving object, sometimes straight but often curved. What am I?

Trajectory 

500

I'm a constant motion all around. The Earth has me, and so do merry-go-rounds. What am I?

Rotation

Law of Energy Riddles

100

I'm created when you eat, and I help you compete. What am I? 

Chemical Energy 

200

I'm the energy of movement, so I'm never still. What type of energy am I? 

Kinetic Energy 

300

I'm stored when you're at rest and released when you move. What type of energy am I?

Potential Energy 

400

I'm invisible, but I power your lights. I travel through wires day and night. What am I? 

Electrical Energy 

500

I'm the heat you can feel but not always see. I travel in waves and warm you and me. What am I?

Thermal Energy 

Random Science Riddles

100

The more you take away from me, the bigger I get. What am I?

A hole 

200

I'm always around you, yet you can't see me. You need me to live, and I can carry sound. What am I?

Air 

300

I'm sometimes hot, sometimes cold, and sometimes just right. What am I measuring?

400

The faster you throw me, the faster I go. But if you let me go, I come to rest. What am I?

500

I'm not alive, but I grow. I don't have lungs, but I need air. I don't have a mouth, but water kills me. What am I?
