Physics stars design mobiles that demonstrate rotational equilibrium. They take measurements and solve related equations for force by graphing, substitution, or determinants. This is a well-developed lesson plan, complete with student...

Learners use this problem to help them to relate to force vectors: Suspend a meterstick horizontally between two tables. Place a 1kg mass in the middle of the meterstick. Notice the bend of the meterstick. Explain why the meterstick...

Students identify and separate the different zones of the beach by observation. They investigate beach zonation by gathering and comparing sand samples gathered from different areas of the beach.

In the deserts of Arizona and New Mexico, some tiny creatures show just how quickly natural selection can turn a mutation into an advantageous adaptation. Watch a video about rock pocket mice, who show that one small change can make all...

In this math worksheet, learners find the solutions to the problems that apply the time-independent Schrödinger equation. They examine the relationship between the mass and energy.

Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...

Fourth graders construct mini-ecosystem, pollute the ecosystem, observe, collect, and record data on the effects of these pollutants on their ecosystem, organize data on spreadsheets, create graphs, and design presentations to share with...

Learners explore reasons for varied salinity in bodies of water. In this geographical inquiry lesson, students use a variety of visual and written information including maps, data tables, and graphs, to form a hypothesis as to why the...

Students collect data on the weather, graph and analyze it. In this algebra lesson, students interpret maps and are able to better plan their days based on the weather reading. They make predictions based on the type of clouds they see.

Students explore the sustainability of our environment, the trend in rising temperatures and the emission of greenhouse cases. Using given data, students test and construct a confidence interval and the difference between two population...

High schoolers explain the historical significance of use of the scientific method in developing the first airplane and appreciate the process involved in developing a new technology.

Third graders measure the heat created at each center.

Students inquire into how the center of mass is the key factor in designing cars. They construct an oddly shaped object and determine its center of mass. They find that engineers are able to predict how objects will behave while they are...

Students explain and understand the circulation of air in the atmosphere. They identify that energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects. ...

Students estimate the size of a sea turtle nest, or clutch, that contains about 120 eggs. They decide what type of container that they are familiar with that could hold a complete nest or clutch. Finally, students calculate the volume...

To stay in business, fashion merchandisers must be able to anticipate what consumers want. By looking at different retail websites, students will look to anticipate what consumers are demanding. Students will then go through the market...
