Students got to understand and see the concept of density. "Density is how solid an object is," said Lauren. We took 5 liquids (food coloring added) and poured them into a cup one at a time. Those 5 liquids were corn syrup, water, glycerin, corn oil and dish soap. Students were able to observe how the liquid did not mix. After observing the concoction and mastering the concept of density, we added solid objects like a candle, washer, eraser, cork, ticky tack and a straw. The washer, ticky tack and eraser fell to the bottom of the cup. Students noticed that the eraser fell slower than the washer which meant it was less dense, and the ticky tack fell much slower than both and was the least dense of the three. The other three objects floated which the students determined were less dense of all liquids and solids. Gabe mentioned, "I thought it was pretty amazing how the liquids did not mix together." Connor thought, "It was pretty cool. I didn't realize you could use liquids as a sensor for determining density for solid matter."
I hope you enjoy learning how the garden changes throughout the school year.
