An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.
Erosion and Floods
Source Institutions
In this activity, learners create models of erosion and floods and learn to recognize both in their environment.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Transit Tracks
Source Institutions
In this space science activity, learners explore transits and the conditions when a transit may be seen.
Light of the Moon
Source Institutions
Learners model the Sun-Earth-Moon system to show what causes the Moon's appearance to change when viewed from the Earth.
Current Events
Source Institutions
Learners model the ocean currents that carry hot water from the tropics to northern latitudes.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Solar System Bead Distance
Source Institutions
In this astronomy activity, learners create a model of the solar system using beads and string.
Moonlight Serenade
Source Institutions
In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
Exploration Vehicles
Source Institutions
Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).
Earth's Water: A Drop in Your Cup
