Wearable devices have become more the norm than the exception. Learners analyze data from a sample device with a regression analysis in a helpful hands-on lesson. Their focus is to determine if there is a connection between temperature...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

There are more ways to use mint candies than to just eat them. In groups, learners design and build race cars using mint candies, drinking straws, Popsicle sticks, index cards, and other materials. They decide on an independent variable...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Technology or engineering teams are given a task to design, construct, and test the efficiency of a structure that will foster an even temperature throughout an entire sunny day. Intended as a long-term project, pupils research, plan,...

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Here is a wonderful activity that allows young engineers to try their hand at designing a bridge out of spaghetti! The worksheet explains the activity and also provides a graph for keeping track of the results. Very good!

Generate ideas about the most scientifically sound ways to prepare foods safely and efficiently during the summer season. Learners will use the GED Connection Science Workbook, so they can practice the skills needed to prepare for the...

Students discover the technology of jet engines through an interactive program. They explore the history of the gas-turbine theory and follow tutorials in how to use them. They finally read about the new Air-Breathing engines.

Fifth graders engage in a activity which offers informational how-tos for conducting research on the Internet. Three search engines are introduced and used to gather information to solve a specific problem.

Students demonstrate knowledge of information sharing skills by discussing each step with their group members. They demonstrate application of information sharing skills by working with a group to share specific pieces of data with...

Students use common materials to build a car. In this car building mechanical engineering lesson, students build a car using a milk cartoon and plastic wheels. They discuss what mechanical engineers do and what makes a car run.

Eighth graders explore mathematics by conducting a series of investigations using a colorimeter. In this math lesson, 8th graders explain the purpose of food irradiation. They collect data and graph them.

Introduce your class to Mars with a resource that provides information about its size, location, length of day, length of year, number of moons, and average temperature. Also includes is information about the lans for past...

Elasticity and viscosity. Help your class understand the similarities and differences with an introduction to viscous fluids. After describing four types of fluid behaviors: shear thinning, shear thickening, Bringham plastic,...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Make the connection between Hooke's law and elasticity with an activity that introduces the class to the behavior of elastic materials. The resource defines stress and strain to calculate the modules of elasticity of...

How temperature affects the efficiency of a solar panel is the focus of the third in a series of eight resources that presents how engineers are able to control the temperatures of photovoltaic panels. Class members find out how the...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Design and build a rover ... then eat it? This activity has groups of two design and build Mars rovers. The teams determine what instruments they want to include with their rover and plan a budget. They calculate the cost of the body of...

Pupils individually determine what they need to know about osteoporosis and how they will find that information. They share their thoughts with a partner before moving on to share with the class. The class arrives at a list of a set of...
