  1. Tuesday Warm Up October 22

  2. A glass beaker is placed on a hot plate. Five hundred milliliters of room temperature water are added to the beaker. If the temperature continues to increase, the water in the beaker will most likely- A turn into a solid B become more dense C turn into a gas D show no change in temperature

  3. Water changes its state of matter when heat is added or taken away. When water reaches its boiling point the particles- A are closer together B stay the same C are moving more rapidly D are moving more slowly

  4. The temperature of water in a beaker measures 87˚C. How many more degrees must the temperature increase to reach the boiling point? A 23˚C B 13˚C C 212˚ D 100˚C

  5. A cotton ball was catapulted from 2 different sized paper clips. The table below shows the distances the cotton ball traveled. Which conclusion is best supported by the results shown in the table? A A cotton ball travels farther when launched from a small paper clip B Using a large paper clip allows the cotton ball to travel farther C A cotton ball does not travel as far when launched from a large paper clip D Using a smaller cotton ball allows it to travel even farther.

  6. A cotton ball was catapulted from 2 different sized paper clips. The table below shows the distances the cotton ball traveled. What variable was tested in the cotton ball experiment? A size of the cotton ball B size of the paper clip C distance the cotton ball traveled D type of catapult

  7. A cotton ball was catapulted from 2 different sized paper clips. The table below shows the distances the cotton ball traveled. What is the significance of conducting three trial runs for the cotton ball experiment? A Conducting three trials shows the differences in the way the experiment was done. B The results of two of the trial runs are incorrect and need to be redone. C Repeating the investigation increases the validity of the results. D It is fun to repeat the investigation a observe cotton balls traveling through the air.
