Two Views of the Universe

Fourth graders study and identify the basic needs of a variety of organisms. Terrariums and aquariums are used to demonstrate what plants, animals, and fish need to stay alive. These two classic models are used to effectively convey what...

How is it that the same animal, living in the same place, at the same time, evolved into two different species? As part of a larger series, an engaging video explains the rise of the chalicothere, the split in evolution, and eventually...

What happens when stars run out of fuel? Pupils learn the incredible sequence of events that occur as a star nears its end. The video compares and contrasts the events in low- and high-mass stars, detailing the cycle of fusion, energy...

Do stars age gracefully? Young astronomers use colored paper and data on luminosity and temperature to model the changes of a star during its lifetime. They then compare models of stars of different mass and radii. 

Part two of this three-part series asks us to think what life would be like if we lived in a binary star system. We are also introduced to black holes and Einstein's theory of relativity. A great clip shown in its three-part entirety or...

This is one super model interactive! Middle and high school science scholars examine scientific models through a simple resource. Guided, hands-on practice allows them to classify conceptual, mathematical, and physical models. Other...

Create three dimensional objects in an applied science lesson. The goal is for your class to recognize, compare, and model shapes. Using cookie cutters and clay or play dough, they create models for three-dimensional shapes.

Discover different dimensions with paper folding. Pupils first read about zero, one, two, and three dimensions, and then learn about the fourth dimension, time. They then use origami to create models of shapes in three dimensions and use...

In this experiment, students will work in small groups to create two different polymers, similar to Flubber and Silly Putty, using Elmer's glue, liquid laundry starch, and Borax. They will then compare the properties of the two polymers....

The Next Generation Science Standards list Developing and Using Models as the second science and engineering practice. The video explains conceptual models and the expectations for K-12th grade scholars. It highlights the progression of...
