« Test Tomorrow | Main | Eggcellent Eggsperiment »

This week students are participating in an Eggcellent Eggsperiment. For the past week we have been studying about cell organelles. Using a chicken egg, students will model how the cell membrane works to allow certain materials to diffuse into or out of the cell. We left the eggs soaking in vinegar over the weekend so that the shell would be dissolved, exposing the membrane. Students will be using various solutions, including salt water, dye, and syrup, to soak the eggs overnight. Each day they will remeasure the eggs, form a new hypothesis, and journal their conclusions. For a downloadable lab sheet, click on the link below:
