Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Students participate in an experiment and learn to record it using the scientific method.  In this biodegradable plastics lesson, students follow the scientific method to complete an inquiry. Students complete an experiment with a...

Students recognize and follow the steps of the scientific method to complete an experiment.  In this scientific method lesson, students use inquiry tools to measure objects.  Students record their data.

Learners study the difference between horns and antlers. They identify animals who have each and draw pictures of these animals. They experience samples of actual horns and antlers.

Students explore the active layer above permafrost and investigate various factors on the insulation value of the active layer.  In this energy transfer lesson, students conduct and experiment to determine the effects of snow cover,...

Students determine sea ice thickness, concentration, and floe size by reading egg codes.  For this sea ice conditions lesson, students color code a map based on prescribed criteria and use the maps to identify changes in sea ice...

Eighth graders analyze physical change in mass. In this chemistry lesson plan, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with...

Students are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and gases and...

Students examine why diffusion and osmosis happen in an egg cell.  In this diffusion activity students demonstrate a semi permeable membrane.

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Looking for authentic hands-on nutritional experiments? High schoolers will perform experiments to test for the presence of vitamin C in several solutions as well as the effect of caffeine on Daphnia. They will also consider the...

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

The Henderson-Hasselbalch equation combined logarithmic terms with the application of carbonic acid as a buffer solution. Scholars learn investigate equation and its applications through hands-on experiments. They collect data and...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Do you know the name for the biological study of interactions? A short presentation with accompanying worksheet introduces individuals to ecology. The materials offer a broad overview of the subject and the levels of organization to...

Third graders use logic and knowledge of mathematics facts to solve problems. They see that pigments can be broken down into separate colors. Pupils recognize the capacity of water to move upward and measure the height water travels up...

Students participate in classroom experiment to gain better understanding of type of environment brine shrimp can best survive. Students then explore effects of common saltwater pollutants on survival of animals in sea.

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...
