Students will get to see and appreciate the prismatic qualities of sunlight by using this 1" in diameter diffraction grating spectroscope. Includes insert. Lesson plan offers two investigations

Students observe the characteristic color of a flame from various elements. They also observe that different elements produce very different, distinguishing colors. Using the spectroscope, students see the light emitted from familiar light sources and compare the appearances. Kit includes 24 spectroscopes, 15 handles, one 4 foot length of wire and one bottle each of chloride, cupric chloride, cupric nitrate, lithium chloride, potassium chloride, potassium nitrate, sodium hydrogen carbonate, sodium chloride, strontium chloride and strontium nitrate. Instructions and SDS included.

Help your students to understand the properties of light energy with this kit. 18 activities, including light transmission, light theory and color, light sources, reflection, refraction and diffraction of light. Teacher's guide included.

Students investigate the physics behind sound energy in this kit. 18 activities include sound wave theory, reflection of sound, force of sound waves and transmission, and many more.

These hands- on experiments reveal the mystery of how light travels. This kit includes instructions for reflecting and refracting light, and includes light theories. A variety of translucent and opaque objects and a teacher's guide with 18 different experiments are also included.

Show your students the exciting properties of electricity with actual experiments which produce visible effects of an electric current, open and closed circuits, switchable control of the flow of current and much more! Includes teacher's guide and enough material for five students.

These magnifiers are perfect for field trips and are priced reasonably to allow each student to have one of their own!
