Science Free Activities/Lesson Plans

Microslide® Viewers Only

This is not a microscope. It is a tool for viewing Microslides® without electricity or special lighting.

Transparent Celestial Globe

Principal stars to 5th magnitude. Full horizon mounting. 16" x 14" x 14".

Wind Tunnel

Students can make a variety of aerodynamic studies with an actual wind tunnel. A wing can be made and lift calculations can be made to give students an idea of how efficient their wing is.

Reaction Timer

A device that measures the amount of time individuals take to respond to light, sound, or touch stimuli. Reaction time relates to general health and is important in sports and everyday life.

Tornado Demonstration Kit

Teacher created! Amaze your students with the tornado simulator. A 20-page teacher's guide packed with seven detailed experiments, included.

The Orbiter

Completely manually operated unit with 6" sun, 15" arm, 4" dia. geophysical Earth globe, cratered moon, transparent hemisphere shield, and lesson plan.

Water Cycle Model Activity Set

This three-dimensional demonstrator creates a water cycle as it occurs in nature. A fascinating, ingenious experimental model that actually causes the rain to fall on the terrain, flow down the slopes, form a body of water, then evaporate in a continuous cycle.

Plant and Animal Cell Model Activity Set

Students can explore plant and animal cell structures with these 8" diameter cell models. Teacher's notebook includes background information, basic understanding, blackline ...

Set of 15 Psychrometer Kits

One kit includes a sling psychrometer with wet bulb, wick, and rubber band; and dry bulb thermometers that rotate on a plastic handle. No mercury filling.

Hydro-Geology Stream Table - Hubbard

This self-contained unit has a virtually unbreakable thermoplastic tray measuring 26" W x 66" L x 6" D. Two separate, independently controllable streams flow from the control panel. Water depth in “lake” is automatically controlled, and the unit empties itself

The Teaching Tank®

This versatile science teaching tool lets students experience what science is, by letting them do what a scientist does.

Landform Demonstration Kit

Students at all levels can visualize the causes and forces that shape the earth’s surface. Over 20 activities and projects demonstrate volcanic action, faulting, and folding.

Animal Track Adventures

Make plaster-of-Paris animal tracks from real animal molds to study natural diversity and adaptation. (Lesson plan from Mike Mansour's in-booth demonstration at NSTA 2008.)

Cavendish Gravitational Balance

Demonstrate the existence of gravitational forces between masses, measure the Universal Gravitational Constant, verify the Inverse Square Law for gravitational forces.  (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)

Free Fall Apparatus

Calculate the average time and the acceleration due to gravity.  (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)

Green Light Laser Pointer

Conduct ray optics experiments; ray paths, refraction, reflection, flare, internal reflection.  (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)

Inertia Demonstrator

Illustrate the effects of acceleration, force, inertia, friction. (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)

Optical Bench Set

Experiment with magnification of a real image formed by a convex lens, the phenomenon of parallax, and the terrestrial (refracting) telescope.  (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)

Refraction Tank with Laser

Explore reflection and refraction.  (Hands-on activities from Dr. Martin Taylor’s Workshop at Texas CAST Conference.)
