94How to Build a Mousetrap Car for Science Class: With Step by step Instructions on How to Make it Go the Distance
Has one of your kids come home with a science project that has you both stumped? The first time this project came home with my eldest son we spent time scratching our heads and having him research the internet. From internet research and two separate school projects requiring this design, my son has made a mousetrap car that goes the distance!

88A grade GCSE Physics experiment - Investigation into the effect of parachute surface area in relation to its fall time
A grade GCSE Physics experiment - Investigation into the effect of parachute surface area in relation to its fall time. I am going to investigate the effect of a parachutes surface area in relation to its fall time. Prediction. I predict that the larger the surface area of the parachute the greater amount of time it will take to reach the ground. This is because a larger surface area will have a bigger air resistance meaning that more air particles collide with the parachute as opposed to a...

89Watchmaker Hublot Recreates Miniature Antikythera Mechanism ~ First Analog Computer Replicated into a Watch
The Antikythera Mechanism which lay hidden at the bottom of the Mediterranean for almost 2000 years challenges the scientific community to rethink their beliefs about the mathematical, mechanical, and scientific abilities of ancient peoples. Mechanisms that were thought to have been produced more recently were found to have existed in approximately 100 B.C.
