Wow! It has been a busy couple of weeks as we head into the final stretch before our holiday break!
One of the highlights from Science this week was our grand EGGSperiment. The kids have been studying cells. As we delved into the parts of cells and their roles, we zoomed in on the cell membrane and its role of regulating what gets into, and out of, the cell.
Our EGGSperiment involved using an egg to represent the cell. The egg had been soaked in vinegar, which dissolves the hard part of the shell, leaving only a spongy “membrane”. The kids measured the mass of the egg and made observations about its size and color. Next, the students soaked the eggs overnight in a variety of consumable liquids such as pop, syrup, ketchup and gatorade.
Finally, with much excitement, the kids reEGGSamined their “cells”. They measured the mass and made more observations about how the membrane did, or didn’t, regulate the entrance and exit of certain substances, such as glucose and water. Connections were then made between the experiment and the real-life functions of plant and animal cells. Overall, we thought the EGGSperiment was EGGS-Cell-ent!
