Line of Sight

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set young scholars on lines that are...

Who would not want an opportunity to taste jellybeans in class?  During this investigation, life science learners hold their noses as they take a taste test and find that our perception of flavor is connected with our sense of smell. In...

And they are off! Using Styrofoam meat trays and balloons, individuals build racers that demonstrate Newton's Third Law of Motion. Pupils run their racers three times and make improvements between each trial. To conclude the activity,...

In a comprehensive unit of activities, learners explore the five senses. Youngsters discover the many different body parts and their functions that allow humans to have sense of sight, touch, smell, taste, and hearing. The best way to...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

This series of images shows how ancient people figured out that the world was round. Each slide shows a ship moving around the globe and coming closer to the line of the observer's sight. This is a very simple resource that you could use...

To illuminate how afterimage occurs, create a star, square, or other geometric-shaped light for learners to look at for 30 seconds. Then, have them explain what they see as they shift their focus to a blank wall. A full explanation of...

Students examine the human ear and its function. In this anatomy of the human ear lesson plan, students view drawings of the ear and learn about the structure of the ear through handouts and glossaries. This lesson plan is part of a...

Using a dimmed flashlight, life science learners can see the network of blood vessels that line the back of their eye. Darken the room and let them try this activity as part of your unit on the eyeball. Also consider some of the other...

Life science learners discover the range of peripheral vision. They compare the angles at which they can detect motion, colors, and detailed shapes.
