Here is an engaging way to help your students explore how concave and convex lenses refract light to produce real and virtual images. Students measure the lenses' focal lengths and discover how lens pairs can be used to make 2 different types of refracting telescopes. From the determined focal lengths, students calculate their telescopes' magnification powers.

Here is an engaging way to help your students explore how concave and convex lenses refract light to produce real and virtual images. Students measure the lenses' focal lengths and discover how lens pairs can be used to make 2 different types of refracting telescopes. From the determined focal lengths, students calculate their telescopes' magnification powers.

Kit includes instructions, activities, and materials to build 8 hand-held refracting telescopes (4 Galilean and 4 Keplerian), each with a 444-mm-focal-length objective lens and a 50- or 150-mm-focal-length eyepiece lens.

 
Rated 5 out of 5 by from Great Fun My students had a blast building and using these simple to make telescopes.

Rated 3 out of 5 by from This product is way too simple. The lenses on this product barely do anything. This would be ok for kindergarten or lower elementary, but I did it with high school and it was way too simple for them. To make this product useful in high school, the lenses need to be stronger and to make this product worth the money I spent on it, I would have liked to see some activities to do after the telescopes are built as well. The product that I got in one kit was definitely not worth the $100 I paid for it.
