Let’s make a telescope with your kids!

A telescope is expensive tool to observe moon, the stars, and etc.
However we can easily make the telescope. 

At first, we should prepare two magnifying glasses (A, B). 
Glass (A) can attach to the distal position. 
Larger lens (A) is desirable. 


Glass (B) can attach to the proximal position. 
On the other hand, smaller lens (B) is desirable. 


Attach these lenses to rectangle or circled pasteboards as shown in the photo. 



Assemble a telescope as shown here. 


Be in a focus adjusting the difference between two lenses. 
Although you can see it is upside down through the hand-made telescope, I think you are surprised at the ability of it. 
















What did you see through these lenses?

Hope you and your kids enjoy the exam.
