Osmosis Investigation

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...

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

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...

Teacher's notes, a materials list, detailed procedure, tips, and extension ideas are all included to make teaching this lesson on photovoltaic cells a sunny spot in your day! After some brief background reading, physical science...

Cell membranes contain many contradictions; for example, they are both oily and strong. The video explains the parts of a cell membrane, the function of each part, and discusses the contradictions. It highlights what happens when...

By exploring the latest research on cell and tissue renewal your young scientists can understand the various internal body parts and systems examined in these studies.

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.

Science concepts often span multiple disciplines. Learn strategies for helping pupils make the connections more effectively using an episode from the Good Thinking PD series. The lesson focuses on the concept of cells and atoms as they...
