EggCELLent Diffusion

High schoolers examine why diffusion and osmosis happen in an egg cell.  In this diffusion instructional activity students demonstrate a semi permeable membrane.

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

No, it really is okay to play with your food! Emerging scientists manipulate popcorn, eggs, and other household objects as they demonstrate multiple cellular processes. The activity, capable of modifications, is designed to reflect the...

A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis in...

Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

Amaze classes with the fact that pruny fingers after a bath are actually the result of osmosis—thanks to the water from the tub. Using an egg, vinegar, and corn syrup, the video teaches about osmosis using an interesting demonstration....

You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...

The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...

Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...
