Bighorn sheep running away in Lower Snake River District of Idaho
Many times, an animal's only defense is speed and running away from predators.
Bee inside flower retrieving nectar
The bee obtains nectar from the flower to make into honey. During this process, the bee is covered in pollen that will be transferred to other flowers for reproduction. Both the bee and the flower benefit from this process.
Conflict resolution: Introduction to cooperative problem solving
An introduction to the concept of and issues involved in Cooperative Problem Solving.

This course covers population and variables; Standard measures of location, spread and association; Normal approximation; Regression. Probability and sampling: Binomial distribution. Interval estimation; Some standard significance tests.
Balsa Glider Competition
The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.
Household Energy Conservation and Efficiency
Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.
Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams (girders) and columns (piers) of simple bridge design. Students learn the steps that engineers use to design bridges: understanding the problem, determining the potential bridge loads, calculating the highest possible load, and calculating the amount of material needed to resist the loads.
You're a Pushover!
The purpose of this activity is to demonstrate Newton's 3rd Law of Motion, which is the physical law that governs thrust in aircraft. The students will do several activities that show that for every action there is an equal and opposite reaction.
Energy Panel at MIT Sloan Africa 2.0
Energy Panel at MIT Sloan Africa 2.0
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They can use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of

Snow Cover over North America during the Winter of 2001-2002 (WMS)
The amount of snow covering the land has both short and long term effects on the environment. From season to season, snow coverage and depth affect soil moisture and water availability, which directly influence agriculture, wildfire occurrences, and drought. In the long term, the part of the Earths surface covered by snow reflects up to 80 or 90 percent of the incoming solar radiation as opposed to the 10 or 20 percent that uncovered land reflects, and this has important consequences for the Ear
