Super Scientist Abby taught our class about water density by filling one cup with fresh water and another cup with salt water. She then dropped a raw egg in the fresh water, and it sunk to the bottom of the cup. Next, she dropped a raw egg in the salt water, and it floated to the top of the cup! We learned that the salt made the water thicker and more dense, therefore, causing the egg to float to the top. Very cool experiment, Abby! Great job!
