Density of Water

 Hello Bloggers today was the first day of term 4. We had a 2 week holiday before we all got to do distance learning again. Today's challenge was super exciting. We had to see which water is denser. Since we didn't have freshwater or saltwater we had to use hot water or cold water. We could also use salt or baking soda to make it more fun. But before we get into the experiment - I have to tell you about our new challenges. We have been put into groups/breakouts for the week. We have to earn points by sharing, posting on our blog, and participating.

Im in Group tahi with Whaea Ocea. But onto the experiment, my hypothesis was that the object would float or sink slowly in cold water because it has a density of (32°F/0°C). So my group made a slideshow of our thinking. Here is a photo of my experiment and my slide with thinking:



( Two coins in water; Right hand side is the cold water, and the left hand side is the hot water. )
 So my question for you is what do you think has the better density? And why?
