Objective:
To simulate what happens when meteors enter Earth’s atmosphere and to understand why this happens.

Standards:
Objects in the Sky (sky object properties, locations, and movements) and Structure of the Earth System (atmospheric composition and properties at different elevations).

Materials:
Large pop bottle filled with water and ½ of a seltzer [...]

Objective:
To demonstrate and interrelate the properties of surface tension and air pressure on how they affect water and water movement.

Standards:
Properties of Earth Materials (physical and chemical properties of water and gas), Structure of the Earth System (atmospheric composition and properties at different elevations), and Structure and Properties of Matter (atoms [...]

Objective:
To demonstrate the properties of air when it expands.

Standards:
Properties of Earth Materials (physical and chemical properties of gas), Structure of the Earth System (atmospheric composition and properties at different elevations), Properties of Objects and Materials (object properties – temperature), Conservation of Energy and Increase in Disorder (heat consists of random vibrations [...]

Objective:
To demonstrate static electricity and to use it to explain how positive and negative charges are attracted to each other. This knowledge of static electricity should also be related to phenomena in the atmosphere such as lightning.

Standards:
Properties of Earth Materials (physical and chemical properties of water), Structure of the Earth [...]

Objective:
To demonstrate how elevation in Earth’s atmosphere and gravitational pull are related.

Standards:
Structure of the Earth System (atmospheric composition and properties and different elevations) and Motions and Forces (gravitation properties and the law for predicting its strength).

Materials:
bathroom scale and a tall building with multiple floors.

Procedure:
Have students weigh themselves [...]
