EiscoLabs Light Box - 27 Piece Optical Kit, Covering 18 Topics in Optics with Full Activity Guide

A wonderful, easy to use kit with study activity book suitable for high school students. Teacher friend wanted to order class set but more were not available. Hopefully m,more will become available.

I bought this kit to help demonstrate different properties and behaviors of light. It works very well on the whole. A lot is included for the price. The prisms are cheap but they do demonstrate refraction and total internal reflection well. They do not make terribly bright rainbows but good quality glass prisms are better for that anyway. Be aware that you will need a 12 volt power supply (such as two 6 volt batteries) which is not included with this kit. They do include plug in leads for ease of attaching to whatever power supply you have though. The slit cards work well as do the mirrors on either side. I understand there is a heat tolerance issue with the fragile color frames but they explain that in the activity book - which is great for using as an accompanying lab with students (answers included).

This is a nice set for the sub 70 price with a few caveats.Pros:Nice assortment of lenses, and they are opaque enough that the students can see the light rays traveling through the lens as well as entering and exiting.Light color mixing is acceptable, enough for students to see the general idea.Ray portion of box works well.Comes with a nice assortment of colored slides.Cost/teaching value is high. My students not only could see what was happening in the lenses but also experimented with different combinations of the lenses.Cons:Using the specified 2amp 12 volt power one of the colored filters warped after about an hour of use.The two curved mirrors are not high quality, it was more difficult for student to see the focal point on these than on an older set I have.The leads get in the way as they plug in the top.Note:It would be nice if this came with some worksheets, even in pdf form. I ended up tracing around the lenses to make sheets the students could use to report results and to investigate nearsighted/farsighted issues. I also made some worksheets with “blank” spots for lenses to go and the rays traced so they had to figure out which lenses to use to get the light to bend in that manner.I gave them a pretest after they had read about ray tracing and then again after the lab. The lab made a difference in comprehension.
