April 23 – World Laboratory Day

Did you know that during the Great Plague of London in 1665 Cambridge University was shut down? Sir Isaac Newton attended the university and was forced into lockdown at home. Sounds like “Stay home. Save lives” isn’t anything new. This requirement didn’t stop Newton. In fact, it was during this lockdown that he invented calculus and parts of optic theory. If that isn’t enough, when he was sitting in his yard he saw an apple from a tree fall to the ground. It was this incident that inspired him to develop an understanding of gravity and the laws of motion.

Today’s activity: Take some time to walk or sit in your yard today and see what you can observe that you may never have noticed before. Or, if you prefer to stay inside, why not do the Rainbow Rubber Egg experiment?

Tell us about what you’ve discovered here. Include a picture if you can.
