2. F.O.A. 08/31/15 1. Karl wants to see which skateboard has the greatest rolling friction, so he rolls each of his three skateboards down a hill from a fixed starting point. Then he measures their stopping distance. What is his variable? F the steepness of the hill G the distance the skateboards roll H the condition of the road J the particular skateboard used 2. Jodi wants to test the law of conservation of mass by performing an experiment with charcoal. Which instrument should she use to measure the mass of her materials? A ammeter B volumetric flask C triple-beam balance D Bunsen burner 1.

3. F.O.A. 09/01/15 1 1. Andrew needs to measure the physical properties of several different items. What property can he measure from a graduated cylinder? F mass G weight H temperature J volume 2. Taylor wanted to find out which brand of “C” batteries lasted the longest. He put one brand of “C” batteries into his radio. He put another brand of “C” batteries into a remote-controlled car. He timed how long each battery lasted before it ran out. His experiment could have been improved by F testing all the batteries in the same piece of equipment. G using “AAA” batteries in the car instead. H weighing the batteries before he started. J measuring how loud the radio could play.

4. F.O.A. 09/02/15 1. Which of the following would be the dependent variable in this experiment? A the temperature inside the boxes B the material covering the boxes C the Sun D. The sizes of the box D the size of the boxes 2. A fifth box covered with red paper was added to the. What property. The thermometer coming out of this box had a reading of 66°F. Red paper seems to have an effect most similar to F black paper. G white paper. H aluminum foil. J clear plastic.
