10. Warming Water Energy # 4 k.Wilkinson 2015 adapted from http://sciencespot.net/

11. Read the prompt. Answer the question. • Two friends put a bowl of very cold water outside on a hot sunny day. The Sun warmed the water. They wondered about the energy of the water. This is what they thought: • Ted: “The very cold water had energy. The Sun provided additional energy to warm the water.” • Amber: “The very cold water did not have energy. The energy in the warm water came from the Sun.” • 1. Which friend has the best idea? Explain why you agree with one friend and not the other.

12. Ice Water Energy #5 K. Wilkinson 2015 adapted from http://sciencespot.net/

13. Answer is Read the prompt. Pick which statement would be your hypothesis • Christine put 5 ice cubes in a glass. Twenty minutes later most of the ice had melted to form “ice water.” There were still some small pieces of ice floating in the water. She measured the temperature, then added 5 more ice cubes to the glass. She measured the temperature three minutes later. • The temperature of the “ice water” increased. • The temperature of the “ice water” decreased. • The temperature of the “ice water” stayed the same. • Explain what happens to the temperature when more ice is added.
