Modeling the Seasons
Students explore the seasons and their attributes. In this geography lesson, students create a 3-D model of the Earth that showcases the elliptical travel of the Earth that causes seasons.
Tech Museum of Innovation
Human Body Exhibit
Explore human anatomy and physiology using models. Scholars study systems of the human body and design a display for a museum exhibit. To complete the activity, individuals create analogous models of their chosen human body systems.

How Can We Make a Model of Lungs?
Fifth graders examine the function of the lungs and create a model of the lungs. Using a plastic cup, drinking straw, plastic bag, small balloon, and a rubber band, they follow step-by-step directions to construct simulated lungs. ...
Smithsonian Institution
Weather Widget
What's so difficult about predicting the weather? Scholars work collaboratively to build a device that models how meteorologists use computers to forecast weather. Team members collect and interpret data while working together to...

Three D Constellations
Students address a major misconception in astronomy, the understanding of scale. The lesson is designed to introduce students to both celestial coordinates and to the first rung on the distance determination ladder, parallax.
Curated OER
Three D Constellations
Pupils are introduced to both celestial coordinates and to the first rung on the distance determination ladder. They convert spherical coordinates to Cartesian coordinates to construct a three dimensional model of a constellation which...

Why Does Water Dissolve Salt?
Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule.
University of Minnesota
Blind Spot
Your eyes each work independently, so how do we only see one image? The quick hands-on experiment encourages young scientists to test their blind spots on each eye individually. After learning where the blind spot is and why it exists,...
