A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

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...

Students examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson plan students demonstrate a semi permeable membrane.

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Learners investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...

Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Learners observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.

Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

A lab activity where students learn the concept of osmosis by observing an egg in different solutions. Included is a procedure for students to follow.

Brief text summary of what students learn in the Investigating Osmosis lab along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Students design and run an experiment to demonstrate osmosis...

This lab will illustrate diffusion and osmosis through a semi-permeable membrane. A chicken egg will be used as the model cell, because the yolk is actually a single large cell. The surrounding egg white, or albumin, contains water and...
