This kit allows students to explore the electrical properties of different combinations of electrode materials using safe, everyday chemicals such as soda, vinegar, and fruit juice as electrolytes. The set contains everything needed for the experiments except the electrolytes. Voltage, current, and polarization effects can be investigated. Contents of the set include a simple cell with electrode holders, electrodes of copper, aluminum, iron, and zinc, a mounted resistor for use as a current load, a multimeter, and a manual.
When is a bicycle wheel a gyroscope? When you put a new "spin" on it. Give our bicycle wheel a spin, then try to tilt or deflect it. Our student-sized bicycle wheel turns freely on its axis and has large, comfortable handles at each end. Because mass is concentrated at the rim, you can tilt the spinning wheel to feel the force of rotation. With instructions.

Set of 8 related 35mm images photographed through a microscope called photomicrographs. Arrows and call outs help the student locate important features. The film is mounted in a clear plastic holder that protects it on both sides. Each Microslide is accompanied by a detailed lesson plan designed to stimulate, inform and question students about the topic under study. Each lesson plan has a pocket in which the Microslide is stored. Lesson plans are printed on heavy tag stock and will serve for repeated use. Box of 10 Microslides.
Includes 12 brass samples. Determine the mass and volume of each sample. The slope of the straight line that results is the density of the material. The attractive wooden holder allows the teacher to see immediately when all of the specimens have been returned!

Introduce your students to the Five Kingdoms through the process of classification. Students view illustrations of various life forms and use a simple, dichotomous key to determine the appropriate kingdom and phylum of each. In the process, they'll gather valuable summary information regarding what each life form "does for a living!" Grades 6-12.

Observe the use of microbes for oil degradation. Model various spill scenarios and monitor the effectiveness of the provided freeze-dried oil-degrading microbe mixture in remediating the waste. Set up a simulated oil spill in water and treat it with the special microbial product to observe the physical changes degradation of oil film over time. Additionally, they simulate three spill scenarios on beach sand, gravel and cobbles in order to observe the difference in degradation rates. The class also explores bioremediation methods for other waste chemicals and compares their effectiveness to traditional clean-up methods. Grades 7-10.
Specifically designed to dramatically and vividly show the classroom a pollutant in water, this kit is designed to permit students the opportunity of determining the presence of animal waste by seeing a dramatic color change that occurs in a lactose broth, students can determine if E coli are present. Grades 7-12.
A compact and economical Color Mixing Apparatus. This updated version of the classic three color light projector uses three low voltage, high power LED's to project easily-seen red, green, and blue light onto a white screen. The projector mounting allows the beam angles to be adjusted to vary the overlap of the three colored images. The intensity of each LED can be adjusted separately by a potentiometer to give a convincing white light or various shades of mixed colors. Colored shadows can also be explored in a darkened room. The set includes a wall mount power supply and manual.
