Blog Post Week 13

 Week 13

After we discussed our previous homework we were asked to define density. We talked with our table groups to come up with a definition and then presented it to the class. I found this interesting because each group had something different, yet accurate. Following defining density we defined matter and properties again. I have liked revisiting what matter and properties are because each week we've gotten more precise definitions. 

                    

Then we redid our M&M and water experiment but with more direction this time. Our only variable for this was the water each group used. We had one table as the control group of just typical tap water, another with salt, and one with sugar, and our table used hot water. We also decided we wanted to compare the M&M dye spread at the beginning, one minute, three minutes, and then finally at five minutes. 

                   

The results of this lab were that the hot water was what made the dye disperse the fastest, a close second being the regular temperature tap water, sugar being far behind, and salt even slower. The reason for this is that in the hot water, molecules move faster. This is something I could see myself doing with an older group of elementary students, and explaining this idea of hot water moving faster with boiling water.
