Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Eighth graders practice using the LIST key on graphing calculators using the proper syntax. They work with the functions of mean, median, and mode in a teacher led lesson and then with a partner on a second data set. They follow...

Students dissect an apple to model the percentage of land on Earth that can be used as a food-producing resource. They use fractions to determine the habitable and agriculture area of the apple.

Pupils compare their hometowns to the towns on the Olympic Torch Relay and complete multi-curricular activities for the lesson. For this Olympics lesson, students complete math, geography, science, and history activities to learn about...

Learners examine the importance of recycling to help the environment. In groups, they make a compost bin on the school grounds recording how the material changes from week to week. They collect other materials for recycling like cell...

Middle schoolers explore different levels of permeability and compare the permeabilities of several different materials. They are introduced to the basic concepts of building design, landscape architecture, and environmental pollutant...

Students examine the inhalation and exhalation process. They create a model pair of lungs from given materials. They discover the technology that has been developed based on engineers examining the respiratory system.

Students write a sketch of an artist or athlete that has pushed the limits on gravity. They explore concepts of rhythm, balance and friction. They examine how engineers design sports equipment.

Learners investigate the effect of thrust on rocket flight. They construct two paper rockets, one with a smaller exit nozzle, and compare/contrast the distances traveled by the rockets.

Students analyze the basic concept of Global Positioning Systems using triangulation and measurement on a small scale in the classroom. They describe a satellite and how it helps in locating a person on Earth. They explain how...

Learners investigate the effect that fins have on rocket flight. They construct two paper rockets that they can launch by blowing through a straw, one with fins and one with wings, and observe and record the results of the rocket flights.

Pupils work together on computers to practice measuring for navigation. They discover that errors in their calculations can lead them in the wrong direction. They examine the need of computers by engineers.

Students examine how a Richter scale operates. They create a booklet illustrating each rating on the scale. They discover how engineers use different measurement tools.

Middle schoolers use the Internet to study how water is treated to make it safe to drink. They use a tutorial on the U.S. Environmental Protection Agency's website to gain this information. They complete a worksheet for the assessment...

Students explore weight by building a spring scale and observing how it responds to objects with different masses. Each team of students can make their own spring scale by following steps which are specifically outlined in the plan. As...

Students examine porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the information to understand how environmental engineers decide on the...

Students research the concepts of center of mass and how to make different things balance. They make symmetrical cut-outs of different "creatures" and experiment with how they balance on a tightrope of string.

Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

Learners construct model landfill liners out of two-inch strips of garbage bags within resource constraints. The challenge is to construct a bag that will hold one cup of water without leaking. This represents similar challenges that...

Students observe a simple water cycle model to better understand its role in pollutant transport. This activity shows one way in which pollution is affected by the water cycle; it simulates a point source of pollution in a lake and the...

Students embark on a scavenger hunt around the school looking for indoor air pollution and mapping source locations. They predict and observe sources of indoor air pollution, understand and give examples of technologies we use related to...

Mix it up by using an intriguing resource that teaches young metallurgists that alloys are a metal mixture. They learn about the advantages of using alloys over pure metals and investigate titanium alloys as an example to finish the...

Pupils examine a stress-strain diagram that compares the advantages and disadvantages of the two common bridge building materials, concrete and steel. The also consider the factors that influence the materials builders choose for their...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...
