So is that what you meant by rubber legs? The activity has pairs subject a chicken bone to vinegar and observe what happens over a period of days. Individuals then write up a lab report and document their observations and findings. 

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Learners review the characteristics of wetlands and list their benefits. After viewing short videos, they identify the organims that make their home in wetlands and how they have adapted. They compare and contrast the characteristics...

Power up! Class members research a type of power production using a great resource featuring a real-world problem. Groups select a type of power generation and pretend that they represent an engineering firm for their chosen power type....

Students study what passive solar design is for buildings and structures.  In this solar design lesson students identify passive solar design techniques.

The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a...

The Diary of a Wimpy Antenna? In the last installment of a six-part series, your class constructs a model of a radio antenna and tests its torque. Pupils use the results to design a better model that resists bending and twisting forces.

Students investigate a waterwheel and the physical properties of energy.  For this waterwheel lesson students create a model waterwheel and calculate the amount of power produced. 

Work with your class to connect series and parallel circuits to hybrid cars. The lesson introduces basic circuit diagrams before having scholars apply the understanding of the difference between parallel and series circuits to...

Students investigate different methods (aeration and filtering) for removing pollutants from water. They design and build their own water filters. Students identify the pollutants in a water sample using sight and smell, explore what...

In this bedroom redecoration project, your young mathematicians become interior designers. They plan, draw, and determine finances for the project. They apply their knowledge of working with decimals, geometric shapes, and problem...

Learners examine how a bill becomes a law in the US Congress. They investigate legislation about global warming. They determine the role of engineers as they educate Congress, the public and other government institutions about global...

Students compare prices then and now. They use the calculated rate of inflation to figure out the equivalent prices today for items sold at the fair and money earned in 1864. They calculate the actual value of a bowl of soup, a dinner,...

Students build and observe a simple aneroid barometer to discover changes in barometric pressure and weather forecasting. They graph changes in barometric pressure for two weeks and make weather predictions.

Young scholars examine the different types of wind patterns. Using common materials, they construct weather vanes to measure and record wind direction over a two-week period. After analyzing the data, they draw conclusions about the...

Students explore wind energy by making a pinwheel to model a wind turbine. They experiment with their turbine by placing it in different locations for optimal energy.

Students discuss the different types of tornadoes and how they form. Working in groups, they record journal entries by conducting experiments with water bottles simulating vortex formation.

Students examine different types of land use by humans and evaluate the ways land is used in their local community. They also consider the environmental effects of the different types of land use. Students assume the role of community...

Students investigate the three types of material stress related to rocks. They watch a PowerPoint Presentation, view an online animation of the three types of rock stress, identify the various types of rocks, answer true or false...

Students investigate major landforms (e.g., mountains, rivers, plains, hills, oceans and plateaus). They build a three-dimensional model of a landscape depicting several of these landforms. Once they have built their model, they act as...

Students engage in a lesson which demonstrates the importance of rocks, soils and minerals in engineering and how using the right material for the right job is important. The students build three different sand castles and test them for...

Students review and evaluate the ways land is covered and used in their local community. They consider the environmental effects of the different types of land use. Students act as community planning engineers to determine where to place...
