The students have been researching why hot air balloons work. They have learned why hot air is less dense than cold air, and how volume and mass relate to density. The final culminating activity was to create their own hot air balloons. It was a wonderful experience for all of the students!

Last week, the students learned the science behind hot air balloons. We studied density, mass, volume, and molecules. For the next two weeks in learning lab, the students will create a poster that will highlight their learning. This week, the students used three different plastic trash bags, and a toaster. Their goal was to experiment with the hot air to figure out which bag should be used to create the final hot air balloon. As they tested the bags, each group had a timer, and sticky notes were used as weights. Through experimentation, the students worked to "fly" the bags for the longest amount of time. Next week, we will build and test the final models. Students will complete the online interactive activity this week while completing the assigned note taking page. The interactive activity teaches the students why hot air balloons fly using the vocabulary mass, volume, and density. The students will also compare the density of four different elements.

The students have been working on the table challenge for approximately 40 minutes. They have been working through the design process like experts! As they test, they have had to make changes to their designs, and sometimes, completely scrap the initial idea to try something else. Creativity, persistence, and ingenuity have really helped some groups shine! |
