This is an activity about the relative sizes of the Earth and the Moon and the distance between them. Learners will inflate a balloon to the approximate size of the moon in relation to a standard globe. They will then hypothesize as to the correct distance between the two and begin to calculate angular size. This is Astronomy Activity 1 in a larger resource, Space Update.

Spreadsheets Across the Curriculum module. Students build spreadsheets to tabulate and graph seismic wave amplitude and energy release to explore the logarithmic scale of earthquake magnitude.

This article provides background information that will help teachers present the science associated with the study of climate, past, present and future. The magazine Beyond Weather and the Water Cycle is structured around the recognized principles of climate literacy. The author explains the science concepts included in the principle related to climate study and research and also identifies additional sources of information.

Spreadsheets Across the Curriculum module. Students build spreadsheets to forward calculate the Earth's aggregate density from combinations of densities and thicknesses of the Earth's four shells.

How many calories are in your favorite foods? How much exercise would you have to do to burn off these calories? What is the relationship between calories and weight? Explore these issues by choosing diet and exercise and keeping an eye on your weight.

This activity helps a student recognize the consequences of Type I and Type II errors in hypothesis testing.

Lecture notes for a lesson at MIT on game theoretical approaches to decision making, including decision making with uncertain information and analysis of risk. The lesson primarily covers game theory and not economic applications.

This activity is a field trip investigation where students gather stream flow, volume, depth & height (area) data on Ramsey County dams (Keller and Round lake), interpret their findings and make in-depth observations in order to assess the effectiveness of dams through the season and estimate the life-span of the dams in years.

The CyberSquad must construct a clock of sorts in order to keep track of the amount of time they have to rescue Dr. Marbles in this video segment from Cyberchase.

One goal of this task is to help students develop comfort and ease with adding fractions with unlike denominators. Another goal is to help them develop fraction number sense by having students decompose fractions. Because the Egyptians represented fractions differently than we do, it can also help students understand that there can be many ways of representing the same number.
