Students use the time-lapse feature of the QX3 Intel Digital Microscope to observe germination of seeds. They use the QX3 Intel Digital microscope to create time lapse video films of seed germination experiments.

Pupils observe the pH change of an acid mixture poured over soil in a filter. Since the buffering capability of soils differs, you may want to do this experiment with several different soil types.

Students observe one of the direct effects of acid water on plant growth. Students engage in an experiment which will take about 2 weeks. Students will understand the effect that acid rain has on plant growth.

In this origin of life instructional activity, high schoolers will review the different theories on how life originated on the Earth including the experiments conducted by Louis Pastuer, Francesco Redi, and Miller and Urey. Students will...

Students experiment with air. In this air lesson, students tape one end of a strip of paper down and blow on it. They place several items in front of the strip to see which items stop the air and which items the air can move around. 

Learners perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Young scholars perform an experiment which will illustrate how to measure the approximate pH of chemicals in water using a pH indicator. They understand that a pH indicator is a chemical that changes color when it comes in contact with...

Fourth graders participate in a demonstration lesson using bubbles in which they determine that air fills the bubbles. Next, they work in small groups as they they experiment with the properties of air at separate work stations. After...

Students conduct an experiment using a small sample from a local water source. They introduce fertilizers and pesticides, separately, and carefully examine the results in their simulated aquatic ecosystem.

Students examine physics by completing a bicycle experiment in class. In this gravity lesson plan, students measure the characteristics of different bicycles and compare their different race times. Students utilize a shoebox,...

Pupils investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-activity series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

Student investigate the lock and dam system of the Mississippi River by creating one for the class to observe. The experiment is completed in conjunction with research bring compiled from different resources for a research project.

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

Explore color through an examination of pointillism and light. Class members view Georges Seraut's famous painting on a computer, zooming in and out to see the details and effects of the technique. They then cover how light and color are...

Students investigate temperature and pressure with simple laboratory equipment. They use a handheld with sensors and probes to study temperature and pressure. Students explore the nature of gases with respect to temperature and are able...

Tenth graders distinguish between acids and bases. For this pH lesson, 10th graders view a PowerPoint and discuss the characteristics of an acid and a base. They investigate natural substances to determine the pH level of each.

Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Hyenas normally hunt alone, however scientists discovered that in Israel, hyenas hunt with wolf packs. When relationships develop between different species, we call it symbiosis. The videos teach about the three types of symbiosis and an...

Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Can human activity influence the colors of moths? The simulation explains how pollution changed the color of tree bark, which led to the survival of a different variation of moths. It also discusses the shift back as air quality improves.

"We Are Never Ever Getting Back Together" makes the perfect theme song for meiosis. The simulation encourages scholars to move the chromosomes and chromatids to properly illustrate the meiosis break up. Multiple-choice questions allow...

Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.
