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.
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
Living and non-living things
Living things often rely on non-living things to accomplish daily tasks. Living things have several characteristics that non-living things do not, such as the ability to move, eat, breathe, and reproduce. Living things and non-living things can interact even though they do not have the same characteristics.
The Marshall Plan and economic recovery of postwar Europe will be discussed.

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
Traditional Chinese Paper
This 1:48 video shows how one Chinese town still makes paper the traditional way. The students will learn how the bamboo is harvested, turned into pulp, and made into paper.
