In this biology worksheet, students identify the different types of reagents being used with the samples as part of an extensive lab experiment.

Fourth graders complete activities to study weather and the water cycle. In this water cycle lesson, 4th graders observe a demonstration of the three stages of water. Students work in groups to complete a water cycle lab activity....

In this membrane permeability worksheet, students read introductory information about the cell membrane structure as it pertains to permeabillity and draw a representation of the membrane as they complete a lab. Students record the...

First-time physicists experiment with pendulums in this physics lesson. They vary the weight of the bob, record how long each takes to complete ten period swings, and then calculate the time for one period. They repeat the procedure,...

Here is a lab that has teenage scientists examining samples of their own blood under a microscope. Learners carefully prepare slides, then make detailed observations and identifying different types of cells using a key. 

Science learners journal familiar ways that the human body can regenerate or heal itself. In small groups, they research and create a poster of current information on stems cells and how they can be used to regenerate. The article for...

Students using the scientific method, study bacteria as a covering surface of the earth in many forms. They discover that not all bacteria is bad and introduce the topic of antibiotic resistance. Science Fair expectations are addressed.

Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Junior crime scene investigators are instructed in two different chromatography exercises. For female suspects, they separate and compare lipstick pigments. For male suspects, they separate and compare ink samples. A data sheet is...

Explore physical science by reading Barthlomew and the Oobleck by Dr. Seuss. Discuss the moral of the story and the discretion an inventor must use when creating something they want instead of something they need. This instructional...

Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...
