Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

In this electrical activity, students draw a schematic design and build a circuit board to grasp the understanding of power conversion circuits before answering a series of 30 open-ended questions including analyzing schematics. This...

When van Leeuwenhoek saw cells and single-celled organisms for the first time, he knew these small things were a big deal! Share his discoveries with young learners through a narrated video, model-building activity, and scale study....

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their...

What one person thinks is a pest may not be a pest to someone else. Here, scholars examine the characteristics of living things and pests through grand conversation and a variety of activities. Class members play a game of pest or not a...

Groups of two to four work collaboratively to engineer a birdhouse that will stay cool in the summer heat. Teams examine several different-colored roofs, testing the efficiency of each with a heat lamp. Then, groups sketch their ideas,...

In a math or life science class, "mini-me" models are created with cardstock to reflect a 1:10 scale of students' bodies. Learners measure each others' heights with meter sticks, and then reduce the size by 10. After this exercise, they...

Open learners' eyes to the challenge of finding safe drinking water – something we often take for granted in our country. The PowerPoint presentation includes images, graphs, diagrams, and even a video to stimulate discussion on how we...

A unique lesson on the solar system, and some of the mathematics associated with it, is here for your high schoolers. Pupils are put into groups of four, and each group is assigned one of the planets from our solar system. They must...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

After cutting down a forest to make a farm, how long would it take the environment to turn an abandoned farm back into a forest? Scholars study this exact scenario while they interpret many charts and graphs of the changing ecosystems as...

Students participate in an hands-on construction of an instrument to measure wind speed.

Young scholars complete online research to study geography's impact on weather. In this geography and weather lesson, students research weather in their city for ten days using an online website. Young scholars bookmark the site, enter...

Students discuss the solar system, the planets, periods of orbit and revolution.  In this space lesson students discuss the importance of the study of Mars and brainstorm ideas on how NASA might solve its Rover design problem. 

Students identify feelings and explore positive ways to handle conflict.  In this mental health lesson students discuss feelings and how to constructively handle them.

Learners investigate force and speed. For this physics lesson, students construct model cars in small groups and perform experiments to identify what factors influence speed and force.

Second graders construct a bar graph comparing local precipitation to that of the Yucatan. In this graphing lesson, 2nd graders will use conversions and problem solving strategies.

Students explore physics. They investigate the strategies used by an engineer to solve a problem. Students construct various models to solve the problem. They display their solutions and explain how they solved the problem.

Fourth graders work cooperatively to investigate the efficiency of various household appliances. They share their findings in three to five minute oral presentations.

Students design, construct and interpret a model of geologic time and investigate change through geologic time.

Students study the sun and how it moves throughout the day.  In this tracking the sun lesson students create a model of the celestial sphere. 

Students construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using growth...

Students examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.

Students identify their feelings and learn constructive ways of handling conflict.  In this conflict lesson students discuss their feelings and when they are feeling a certain way what they can do to remedy the situation.
