How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

In this science worksheet, students find the answers to various types of heredity problems. They use the sheet to set goals for completing the unit.

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Students experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

The human body is an amazing thing! Explore the body with your high school class as they investigate each system in detail. They learn components of each organ system and disease processes that can negatively affect general health and...

Students explain the following processes: bacteria transformation, genetic recombination, and antibacterial breakdown of bacteria. They follow lab protocol and use the scientific method: to make predications, and to explain an unexpected...

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Young engineers consider how to apply accelerometers and sensors to help prevent falls in elderly people. They consider forces of motion and gravity as part of the engineering design process.

Students isolate DNA from different food sources. In this biology instructional activity, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students study the livers parts and functions then follow a lab experiment to watch first hand how the gut uses bile to physically break down fatty substances into smaller pieces.

Students explore the process of fermentation through the process of making Sauerkraut. Students use their observational skills and their five senses to create an articulate description of their lab created sauerkraut. They discuss the...

Learners explore the surface area to volume ratio in cellular respiration. While participating in an interactive lab experiment, they examine proportional surface area and discuss nanotechnology. Students observe the effectiveness of...

A hands-on activity which allows students to learn about cellular respiration. This lesson contains a range of investigations testing the rates of cellular respiration to demonstrate the relationship between metabolic rates of...

Students use word processing, presentation, and spreadsheet software. In this multi-day computer software usage lesson, students complete a research project that requires the use of a word processor, Excel, FrontPage, and PowerPoint to...

Reward biology learners for working hard in their mitosis lesson with a sweet snack at the end! They begin by twisting apart creme-filled cookies and using the icing as a cytoplasm. Colored candy sprinkles make up chromosome pairs,...

Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Like good scientists, kids often want to see first-hand why things are as they are; they can do just that in the starch-testing photosynthesis activity found here. Depending on the age of your pupils, you may wish to do the investigation...

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.

Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.

Learners discuss the structures of a bone and observe a demonstration of bony materials.

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...
