Learning About Screws and More Harmonograph!

Today, we started with looking at different types of screws and there uses. Like Flat Head and Pan head,  the tread count and the size. We found out about mechanical screws are more useful with already made holes in plastic or metal, and that pointed tips are used more for wood.

When working with the Harmonograph, we made a second pendulum and are starting to mount the flat piece of wood on top. We have found a way to mount it on a flat surface, we placed two right angle triangles with a square taken out of the angled slant, for the screw. We attached it to both sides of the wooden pole, we are thinking of hot glueing it on!
