Young scholars participate in a simulation of the equal and unequal distribution of the earth's renewable resources. They discuss renewable resources and how food resources can increase and decrease, participate in the simulation, and...

Students investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry...

Learners analyze how engineers study temperature inversions and convection currents to understand why pollution levels may be higher in some areas than others. They participate in an experiment that allows them to build simple models to...

Students participate in a series of timed relay races using their skeletal muscles. They compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space. They list the three types of...

Seventh graders describe how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow. They consider the affects of pollution on groundwater supplies and write a letter drawing...

Students study the main methods to measure earthquakes; the Richter Scale and Mercalli Scale. They make a model of a seismograph and investigate which structural designs are most likely to survive an earthquake.

Fifth graders inspect the basic functions of the immune system and determine how viruses and bacteria invade the immune system. They also explore what happens to the immune system in outer space.

Students examine the basic concepts of radio waves and magnetic fields. They study how the AM radios are built and demonstrate the concepts of amplitude and frequency.

Students discuss flooding and its causes. They view a Powerpoint presentation about floods and prevention methods. After creating a model with clay and pans, they investigate river behavior in various terrains with different amounts of...

Students create a pie graph using M&Ms to demonstrate the composition of air. They label each section of the graph, and list the fractions from largest to smallest.

High schoolers work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They analyze Ohm's Law, power, parallel and series circuits, and ways to measure voltage and current.

Students analyze how the digestive system works by taking the food we eat and breaking it down for our bodies to use for various reasons. They list the major components of the digestive system and draw a diagram. They explain how...

Students study concepts of energy and energy transfer. They look at how these concepts apply to musical instruments. They study the law of conservation of energy. They use the concepts studied in the lesson to design a musical instrument.

Students build and evaluate simple models to understand the greenhouse effect. They explore the role of increased greenhouse gas concentration in global warming, and the implications of global warming theory for engineers, themselves...

Students study how industrial technology helps clean up and prevent air pollution. They role play as engineers to examine methods of engineering pollutant recovery methods such as scrubbers, electrostatic precipitators, cyclones, and...

Learners explore solid waste and its effects on the environment. They explain some of the major problems caused by waste disposal and the use of landfills. They suggest ways to reduce the amount of solid waste going into a landfill.

Students explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they investigate filtration and aeration processes as they are used...

Students define and examine the connections between sound and music and how engineers design instruments. They listen to examples of musical instruments, view a demonstration of a tuning fork and bottles filled with varying amounts of...

Young scholars examine and observe how many human-made objects get their basic design from things in nature. They listen to the book "Nature Got There First," compare/contrast hollow bones with drinking straws, bird beaks and tool...

Students investigate how pollution is a global issue. They locate the countries affected by radiation from Chernobyl, sequence the progress of radiation transport from Chernobyl and plot the pollution points on a world map, and read and...

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...

Students examine how they use and waste natural resources. They participate in a class discussion about natural resources, in small groups complete a worksheet identifying ways students misuse natural resources, and create an...

Students create and observe a greenhouse effect model and discuss the implications of global warming theory for engineers, themselves and the Earth. They discover that Global warming is becoming an increasing concern as we learn more...

Students study three different muscle types and investigate the affect of space travel on astronauts' muscles. They examine how exercise has a positive affect on muscle both on Earth and in space while looking at engineers' roles in...
