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....

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...

After studying DNA replication and the genetics of inheritance, this slide show is useful for explaining specific mutations that can happen and result in an illness. Sickle cell anemia, and cystic fibrosis are explained on a genetic...

Seventh graders study biological systems and how they reach equilibrium.  In this system balance lesson students divide into groups and complete an osmosis lab activity.

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...

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...

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...

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...

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 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...

Advanced placement biology aces list systems that have evolved over time, adaptations, and structure-function relationships. The resource requires plenty of writing to answer these questions, so allow a few days for them to complete the...

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.

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 design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!

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...

In this biology trivia worksheet, students write short answers to 101 questions about animal classification, human anatomy, animal facts, and attributes of organisms.

In this biology worksheet, students identify and locate various vocabulary terms related to cells of the body. There are 31 biology terms located in the word search.

Although there are a few missing titles in this collection of slides, if your class has prior knowledge of genetic diseases then this resource could be useful. The mechanism of genetic inheritance are covered and both flow charts and...

The basics of mutation types and some potential effects of those are described and diagrammed here. Each detail is very clear and includes the labels and translation change exhibited. A great slideshow to expand on DNA replication issues.

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

For this biology worksheet, high schoolers examine the process of respiration and specifically look at the biochemistry of gas exchange at the alveoli.

In this biology learning exercise, learners look at the function of filtering in the nephron of the kidneys and the biochemistry is emphasized.

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have...
