  5. You’re on a cart, initially at rest, throwing balls at a partition that is rigidly mounted on the front of the cart. If the balls bounce straight back, as in the figure, then is the cart put in motion? Yes, left Yes, right No Don’t know Eric Mazur, “Peer Instruction”

  6. When you lose 10 pounds, where does most of the weight go? • Out of the body in secretions (urine, feces, and/or sweat) • Out of the body in air you exhale • The body uses it up as energy • Half out of the body in secretions and half used up as energy Origin unknown

  7. Using Images

  13. What texture does this rock display? A. Phaneritic B. Aphanitic C. Porphyritic D. Glassy CU SEI

  14. Prediction & Experiments

  15. Show students that a light bulb lights up when it’s connected to a power source through a weak acid. What will happen if I use a 100% acid solution? (A) Brighter (B) Dimmer (Most students answer brighter; but the light bulb won’t light in a 100% acid solution) 15 Origin unknown

  16. Observations of a particular ecosystem lead you to propose this food web. If a disease causes the population of frogs to decrease, what would you expect to happen to the population of rabbits? Increase Decrease Stay the same Ian Beatty, UMass Amherst

  17. If you lower a 1.5 kg mass on a string into a 5 kg beaker filled with water, what happens to the reading on the scale? • increases to 6.5 kg • increases to a value < 6.5 kg • increases to a value > 6.5 kg • stay the same (UBC CWSEI)

  18. Which action will increase the concentration of the solution? I. Add more CuSO4 II. Evaporate water III. Drain water a. I only b. I and II c. II and III d. I and III e. I, II, and II Using PhET interactive simulation http://phet.colorado.edu

  19. A cup filled with water has a hole in the side through which the liquid is flowing out. If the cup is dropped from a height, what will happen to the water flowing from the cup? It will keep on coming out, flowing the same as before It will keep coming out, but it will flow a bit slower than before It will keep coming out, but start to flow upwards It will keep coming out, flowing horizontally with the falling cup It will stop flowing (Cynthia Heiner)
