Presentation Transcript

  1. Changing Misconceptions in Physics and Physical Science Students Presented by: Catherine Charnawskas and Margaret Milligan

  2. Quiz • Website: https://www2oakland.edu/secure/sbquiz/index.cfm • Quiz helps to diagnose common misconceptions that science students have. • Full quiz covers: physical science/physics, chemistry, biology, and astronomy.

  3. Topics we will cover today • Newton’s Laws • Gravity • Electricity and Circuits • Light • Density and Buoyancy

  4. Newton’s Three Laws • Newton’s First Law An object in motion will remain in motion, an object at rest will remain at rest, unless acted upon by an outside force. • Newton’s Second Law Force = mass * acceleration • Newton’s Third Law For every action, there is an equal and opposite reaction.

  5. Newton’s Demos and Lab • Question: Can one person “out pull” another person? • Two volunteers • Two spring scales • Hypothesis? Results? Explanation?

  6. Newton’s Demo and Lab • Question: Can I push you away? • Two Volunteers • Two chairs with wheels (skateboards or roller skates also work) • Hypothesis? Results? Explanation?

  7. The Effects of Gravity • Question: What happens if a feather and hammer are dropped at the same time (in the absence of air resistance)? • Video Clip: Astronauts having fun! • Hypothesis? Results? Explanation?

  8. Newton’s Demo and Lab • Question: Can you remove the paper towel without moving the beaker? • Volunteer • Paper Towel (brown school paper towel works best) • Stack of Beakers • Hypothesis? Results? Explanation?

  9. Electricity and Circuits • Question: How many ways can you light the bulb? • Light bulb and holder • Alligator clips and wires • Batteries and battery packs • Hypothesis? Results? Explanation?

  10. Electricity and Circuits • Question: Can we make a human circuit? • Human volunteers! • Hypothesis? Results? Explanation?

  11. Density • Question: Is your soda dense? • Can of regular and diet soda • Tank of water • Hypothesis? Results? Explanation?

  12. Wrap-up • All the handouts and PowerPoint can be found at http://www.msu.edu/~milliga9/mdsta.htm
