High schoolers examine why diffusion and osmosis happen in an egg cell.  In this diffusion lesson students demonstrate a semi permeable membrane.

Sixth graders examine microorganisms. For this germs lesson, 6th graders observe and record data on the positive and negative aspects of microorganisms.  Students complete activities, view a film, and explore websites. 

Students measure angles of refraction as the light travels through gelatin.  In this experimental lesson students complete a refraction lab and plot their data.

In this weathering and wind worksheet, students simulate the effects of weathering by wind using 2 canisters, 2 types of sandpaper and 2 sugar cubes. Students swirl the sugar cubes inside the canisters lined with fine and course...

Learners explore how the earth is a magnet and that magnets have two "poles".  In this magnetic lesson students complete an activity by designing their own compass. 

The intent of this lesson is to introduce young scientists to the steps of the scientific method. To this end, they consider the question, "Which brand of battery lasts longest?" In this case, the experiment is carried out as a class,...

Spur a discussion of germs using this lesson. Learners conduct an experiment with potatoes to determine how germs are transmitted. They then discuss ways to prevent the spread of germs. The emphasis is on hand washing.

Students make observations and present interpretations based on their observations and on their prior knowledge. They use images to answer questions and make formulate hypotheses.

Students participate in an experiment in which they try to stop algae from growing. In groups, they develop a hypothesis and test it while making changes to the experiment along the way. They make observations and organize their data...

Young scholars make a grid and coordinate system map of their classroom as they investigate why it is important to have a common map making system. They look at how landmarks are used for navigating an area.

Young scholars examine a set of data to try to determine the amount of cloud cover. In groups, they make a list of items that reflect light in the atmosphere and how different amounts of it can change the temperature. Using...

Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...

Learners investigate the effect of day length on animal migrations. They view a Powerpoint presentation, identify their own personal migrations and cues, answer discussion questions, and test a hypothesis about seasons.

Young scholars look at the findings of a Hopi Indian dig site in order to reconstruct the sequence of events that occurred in the past. They examine the stratigraphy while making multiple hypothesis about the artifacts and their...

Students investigate woodbugs. In this scientific investigation lesson, students explore the steps scientists take when conducting an investigation using live specimens. Students explore habitat preferences for woodbugs in various...

Students complete their examination over the Jewish Diaspora. Using population figures, they discover the importance of percentages in exploring trends. They use their own ethnic group and determine how it is represented in the United...

Students explore solar and lunar eclipses and how the sun, Earth, and moon cause them.

Students become familiar with the concept of spectroscopy or the study of the interaction of matter with electromagnetic radiation. They prepare solutions and measure absorbance at different wavelengths. Pupils comprehend that mater and...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

In this sequence worksheet, students find the limits of given sequences and prove theorems. This one-page worksheet contains four multi-step problems.

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Third graders review the scientific method and how and in which steps scientists use observations and measurements. Then as a class, they hypothesize which ramp will send the car the farthest. They break into groups and send cars down a...

Students use the scientific method to solve a teacher scenario. They bring in M&M's. Students are given a copy of the scientific method. They first come up with a problem. Students are told that they are going to conduct an...

Learners identify sources of Food Borne illness and their prevention. They formulate hypotheses based on collected information. Pupils become aware of Nutrintional value of food. Students collected data are synthesized to formulate...
