Students observe the process and results of transpiration from a plant in their schoolyard.

Students will compute the approximate travel time to planets in the solar system using different modes of transportation.

Students model the position of the planets around the Sun and then model viewing them from Earth on any given date.

In this illustrated problem set, students use pi to compare the sizes of Mars landing areas, calculate the length of a year for a distant solar system object, measure the depth of the ocean from an airplane, and determine the diameter of a debris disk.

This lesson uses stacking cubes as a way to graph precipitation data, comparing the precipitation averages and seasonal patterns for several locations.

In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.

Students use global temperature data to create models and compare short-term trends to long-term trends.

In this illustrated math problem, students use the mathematical constant pi to calculate the shape of an asteroid's orbit.

Students learn to describe rocks using candy bars as familiar models.
