Objective:
To demonstrate a solar eclipse.

Standards:
Objects in the Sky (sky object properties, locations, and movements) and Earth in the Solar System (position, properties of sun, earth, and its moon; predictable motions explain day, year, moon phases and eclipses).

Materials:
coin and a large stationary object outside or across the classroom.

Procedure:
Close one [...]

Objective:
To demonstrate Bernoulli’s Law and explain its relation to air pressure differences and what happens because of these differences.

Standards:
Properties of Earth Materials (physical and chemical properties of gas) and Motions and Forces (laws of motion).

Materials:
two empty aluminum pop cans and a flat surface.

Procedure:
Place the empty cans a few [...]

Objective:
To understand how sound is produced and what creates variance in the tone or pitch of sound.

Standards:
Position and Motion of Objects (sound is produced by vibrating objects – how and why pitch changes).

Materials:
One piece of cellophane that is two inches square.

Procedure:
Tightly stretch the piece of cellophane [...]

Objective:
To demonstrate air pressure and its effects and influences on surrounding materials.

Standards:
Structure of Earth System (atmospheric composition and properties at different elevations) and Structure and Properties of Matter (properties of solids, liquids, and gases).

Materials:
large index card, glass or cup, and water.

Procedure:
Fill the glass with water [...]

Objective:
To demonstrate the concepts of exponential radioactive decay and half life in a hands – on and graphical manner.

Standards:
Energy in the Earth System (internal sources of energy – radioactive decay) and Origin and Evolution of the Earth System (geologic dating methods).

Materials:
One hundred pennies and a container to hold [...]
