Mrs. Bradley's Grade 2
In our "Hot and Cold" Unit in Science, 3 of the objectives in the Program of Studies are as follows:
In order to make it a fair test, each group used the same materials: One red solo cup, one sheet of newspaper, one piece of bubble wrap, one sheet of tinfoil and 4 cotton balls. Each group designed their own cooler and each group used different techniques to keep their ice from melting. Once our coolers were finished, we put little cups of ice in them and left them for an hour. To measure how well the designs worked, when the time was up we poured out the water that had melted off the ice. The students determined the less water that poured out, the more successful their design was. The next step in our learning is the apply what we know about insulators to expand our learning of animal adaptations. Hint: Blubber is an excellent insulator!
