Glucose

Challenge your biology class to analyze an experimental setup, in which a selectively permeable membrane separates two distinct solutions. They consider the concentration of the contents and answer ten questions pertaining to the...

Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

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...

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....

Students examine the basics of starch and how it is used in food. In this photosynthesis lesson students experiment with variables that affect starch production in photosynthesis.

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

Learn about diffusion, osmosis, and concentration gradients and why these are important to cells. [18:58]

Students investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into higher...

A detailed explanation of the processes of diffusion and osmosis. [18:59]
