100

The invisible area where a magnet can push or pull another object. 

Magnetic field

100

This is the galaxy our solar system calls home.

Milky Way Galaxy

100

When you touch something cold, this flows from your hand to the object.

Thermal Energy (or heat energy)

100

The sun provides energy that drives many processes on Earth's surface. This inner source also contributes heat for processes underground.

Earth's interior or core

100

When baking a cake, the ingredients turn into something new with different properties. This is an example of this kind of process.

Chemical Reaction

200

This force holds the solar system together. 

Gravity

200

The sun appears to rise in the east and set in the west. This daily cycle is caused by this motion.  

Earth's rotation (spinning on axis)

200

This measurement tells you the average kinetic energy of particles in a substance.

Temperature

200

When the sun heats up water in lakes and oceans, this process happens.

Evaporation

200

In a chemical reaction, these stay the same, even though they are rearranged.

Atoms

300

If you slide a book across a table, this force slows it down.

Friction

300

These smaller space companions travel around planets.

Moons

300

Even though a pot of water and a cup of water are the same temperature, the pot has more of this.

Thermal energy

300

The reason rivers flow downhill and rain falls toward the ground is this invisible force.

Gravity

300

Rust forming on iron is an example of this type of transformation.

Chemical change

400

This part of a magnet is where the force is strongest.

Poles

400

If you look at the night sky for several hours, stars seem to move. This movement is not real—it’s caused by this.

Earth's spinning axis (rotation)

400

This term describes the energy moving from a hot object to a cooler one.

Heat transfer

400

When water vapor cools in the atmosphere and turns into droplets, this is happening.

Condensation
400

This evidence—like bubbling, temperature change, or color change—can help you identify this kind of reaction.

Chemical reaction

500

Gravity between the moon and Earth causes this rise and fall of ocean water.

Tides

500

What two factors cause us to experience seasons on Earth? 

The tilt of the axis and the orbit around the sun.

500

In science, “heat” doesn’t mean hotness—it refers specifically to this.

Energy moving from one object to another due to a temperature difference

500

Water exits plants through small pores in their leaves in this process.

Transpiration

500

New substances formed during a chemical reaction are different from the starting materials, which are known by this name.
