Isaac Newton

Isaac Newton was clearly one of the most influential scientists of all time. He determined techniques to measure the mass of planets and calculate a trip to Mars. And of course, this was long before space flight! But he made one major mistake, assuming that the effect of gravity could exceed the speed of light. Ooops!! But we can forgive him for that right? Have your students do some of these investigations: 1. Research the Black Plague that affected the time of Newton. How was it similar to out recent pandemic and what were the similarities with how they dealt with it? 2. Have students write out Newton's three laws and then give examples of how they apply in day to day life. Draw or "act" these out in a class presentation (better than just writing them out in sentences). 3. Newton's 1st Law is essentially a law of inertia. Ask students to tell you which will travel further with the same force acting upon it: a baseball or a bowling ball. Try this outside, if you have a 5 pin bowling ball (which is easy to find at a local alley). Try to promote a deep discussion as to why objects want to stay in motion or at rest, depending on their mass and the forces acting on them. 4. Use a skate board or a chair on wheels and create some inertia experiments with students as the mass. What other factors must be considered? Is it always true that a heavier object will roll down a hill faster than a light one? Will a heavy object fall faster than a light one? Drop some items with varying weights. Have students design experiments around these commonly misunderstood concepts. Encourage the scientific method, changing one variable at a time. 5. Give students the option of doing a biographical research on Isaac Newton and have them present their findings to the class. 6. Some students may find some interesting numerology when looking at the birth and death dates of Galileo, Newton and Stephen Hawking. Investigate and report. 7. For your advanced students, challenge them to use Newton's 2nd Law and the universal law of gravity to determine the mass of Earth. Or how about using the formula for kinetic energy and combine it with Newton's laws of gravity to determine the escape velocity needed for a rocket to leave low Earth orbit. Then try using the same formulae to determine the size that Earth would have to be in order to be a black hole. Even if they haven't seen these worked out, there are a lot of online tutorials. The challenge is to see if they can understand the process and then teach the rest of the class.
