Water Property Demo

In our water property demo, my partner and I demonstrated the relationship between density and temperature. We put cold water in one clear plastic cup and hot water in another. Using food coloring, we dyed the cold water blue and the hot water red so they would be easy to distinguish.

We demonstrated that hot water is less dense than cold water. When hot water is placed on top of cold water, it floats, but when cold water is placed on top of hot water, it settles to the bottom.

Overall, our demonstration went well. My partner was absent on the day we were supposed to present, so we had to present the next day, and Ms. Wood was not there to film our presentation. However, this didn't really set us back, and the demonstration itself went over as we hoped it would.

From the other demonstrations, I learned cohesion is when water attaches to itself, adhesion is when water attaches to other objects, saltwater is more conductive than freshwater,porosity is the distance between rocks, and the normal pH range for stream water is around 7.6.
