The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
Tiny Particles, Big Trouble!
Source Institutions
In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
False Memories
Source Institutions
Use this activity (10th on the page) to help learners explore memory and how sometimes your brain makes up its own memories. Learners will read and try to remember the words in list #1.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Vanishing Rods
Source Institutions
This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.
Diffraction
Source Institutions
In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.
Dress Like a Frog
Source Institutions
In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.
Enzyme Action
Source Institutions
In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.
Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.
Why Are Two Eyes Better Than One?
Source Institutions
In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.
Depth Perception
Source Institutions
In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.
Think Fast!
Source Institutions
This is a quick and simple demonstration about reflexes (fourth activity on the page). One learner stands behind a see-through barrier like a window or wire screen.
Drop IT!: Depth Perception
Source Institutions
These two activities (4th on the page) demonstrate the importance of two eyes in judging depth.
Accommodating Accommodation
Source Institutions
In this demonstration (18th on the page), learners conduct a simple test to explore how the cornea refracts light, which is further bent by the eye lens through a process known as accommodation.
Shifting Backgrounds, Shifting Images
Source Institutions
In this quick activity/demonstration (5th on the page), learners explore depth perception.
Homologous Shoes?
Source Institutions
This "concept demonstration" provides learners with a concrete example (a pair of shoes in a classroom "cell") of what homology means.
