Students describe and illustrate the process of diffusion in selelctively permeable cell membranes. They are asked to respond to what they think will happen when food coloring is dropped in a bowl of water. Other activities will be...

Although it contains some formatting issues, the Word document here contains good questions about osmosis and diffusion, and is easy to edit as needed. Designed as a study guide, you could use the information here for warmups, ideas for...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

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.

Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

Students examine the relationship between cell surface area and the ability of materials to diffuse through a cell. They participate in an experiment in which they determine which materials diffuse easier than others. They complete...

Students develop the concept of diffusion. For this science lesson plan, students demonstrate diffusion of molecules of matter in various states.

In this cells worksheet, students will review cell characteristics and structure and different types of cells and what role they play in the body. Students will investigate experimental results of the influence of sucrose on the...

Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....

In this biology activity, 9th graders describe what osmosis is and how it explains the fact tat a watery syrup forms when you put sugar on strawberries. Then they describe how proteins made by ribosomes leave the cell. Students also...

In this water and diffusion worksheet, students will explore the characteristics of water and the water molecule. Students will also answer questions about diffusion and the movement of materials due to concentration differences. This...

Students are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher sprays...

With a multitude of questions, this worksheet offers students the opportunity to review their knowledge about the cell cycle. Question types include true/false, word bank, and completing a table about the differences between interphase...

In this cells instructional activity, students review the different types of cells. Students identify the organelles found in an animal cell and determine the function of these organelles. This instructional activity has 14 matching, 6...

In this cells worksheet, students define 14 words associated with cells. They answer 12 short answer questions about the structure and function of the cellular system.

In this science activity, students investigate the cell and the process of osmosis and diffusion across the cell membrane and then perform an experiment.

The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within...

In this homeostasis learning exercise, students complete a crossword puzzle with 22 question on homeostasis and cell transport. They identify the different ways substances are transported in and out of the cell.

Students observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Young scholars 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...

Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...

In this biology worksheet, students locate and identify various vocabulary terms relating to cells and microscopes listed on the right. There are 26 biology terms located in the word search.

Active and passive systems used to transport materials to and from cells are the subject of a comprehension worksheet that asks readers to use information from the article to answer a series of questions based on the text.

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...
