In the three-lesson module Cells and Models, students explore the use of models in science as they compare the benefits and limitations of various representations of an animal cell, including the Looking Inside: Cells app, and develop a cell model of their own. Optional extensions expand students’ learning as they refine a cell model to illustrate cell specialization, or explore modeling cell systems through the example of nerve cells.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Laptop/Desktop, VR Headset (Optional).

Here is a 1-5 day unit on electromagnetic radiation that features a teacher guide and student activities with extensions.

Captain Ed Smith and his dog, Rocco, are exploring all the amazing senses animals have. Join him and discover with them.

Nita lives on Coco Island in the Indian Ocean, and is learning more about the Sun, the Earth, and the Moon. Join her and learn about day and night.
