This video shows you how to make a homopolar motor, a simple motor made from a battery, magnet, and copper wire. This is a fun simple science experiment or demonstration, that you can turn into a science fair project by measuring the rotation speed of the motor if you change a variable (like the size of the magnet or the shape of the wire coil). Written instructions are available on the Science Buddies…

Lenses required for this project (note: two different types!):
https://www.homesciencetools.com/product/lens-double-convex-500mm-f-l/?aff=SB1
https://www.homesciencetools.com/product/lens-double-concave-150mm-f-l/?aff=SB1
This video shows how to build a simple refracting telescope, also called a monocular or a spyglass, using two lenses. One lens is double convex (converging) and one is double concave (diverging). This results in a magnified right-side-up image instead of the inverted image…
This video explains everything you need to know about solutions and how to prepare them. We will also introduce the concept of solution concentrations and go through some example calculations.
