- Fill one jar with cold water and add food coloring.
- Fill the other jar with the hottest water you can while still being able to touch the jar.
- Add a different color of food coloring to the hot water.
- Place an index card over the opening of the jar with hot water.
- While holding the index card in place, flip the jar over and on top of the jar with cold water.
- The less dense hot water floats on top of the denser cold water.

Fill the other jar with the hottest water you can while still being able to touch the jar. Add a different color of food coloring to the water. Place the index card over the opening of the color water jar. While holding the index card in place flip the jar over and on top of the jar of hot water.www.forgetfulmomma.com/2020/04/14/temperatur…Hot water is less dense than cold water, and you can demonstrate this in a very visual way. Take two small jars of water, one hot and one cold, and put food coloring in each so that they can be easily seen. Put a thin piece of cardboard over the mouth of the jar of hot water and flip it upside down.sciencing.com/water-density-science-experiments-…When water is heated, the water molecules move faster. They bounce off one another and move further apart. The extra space between the molecules means the same volume of water weights slightly less and is less dense than cold water. When we put the hot water on top, the less dense hot water floats on top of the denser cold water.navigatingbyjoy.com/2014/01/19/amazing-water-trick/How do you do hot and cold water density experiment? Fill one jar with cold water and the other with hot water. Pour blue food coloring into the cold water and red food coloring into the hot water. Make sure both jars are completely filled with water. To avoid spills, place them in the shallow plate.myworldtheirway.com/2020/01/hot-and-cold-water-…This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so I would either do it outside or put the jars in a tray. The demonstration works as cold water is more dense than hot water so the hot water sits on top of the cold.www.science-sparks.com/hot-and-cold-water-densi… - People also ask
