The Moon’s Phases

New Moon: when the moon is invisible.

Waxing Crescent Moon: a crescent which is growing from the right side.

First-Quarter Moon: A half-moon growing from the right side.

Waxing Gibbous Moon: A Gibbous that is expanding toward the left side.

Full moon: a moon that is full.

The Periodic Table

This is a triple-beam balance. It is used for weighing mass.

These are graduated cylinders.

How do we get energy?

1. The sun gives heat to the plants.

2. The plants make sugar and the animals eat the plants.

3. Hunters hunt the animals or eat the plants.

This is a close-up look at copper when it is a solid and a liquid.

Helium is lighter than everything in the periodic table except hydrogen.

WAVES Waves carry energy. That energy is kinetic energy. When you drop something into the water waves will form. penny

This is copper wire. If you were to cut it in half a billion times, then the smallest piece is called an atom. This is an atom!

The Brass Experiment

I have a brass ball and a brass ring.

See that the brass ball fits the brass ring.

Now heat the brass ball on fire. Because of the heat it expands!

Surface Tension

The paper clip sunk when I put it in the water!

But when I lower it carefully on the water with a fork, it floated because of surface tension.

But when I add soap, it sinks because soap breaks the surface tension.

This is a record groove.

These are CDs.
