Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

Here is a lab activity adequate for use with any full lesson on environmental factors that shape animal adaptations or marine animal characteristics. Pupils will discuss the role plankton plays in the environment and filter-feeding...

Students identity the components of electron transport system through role play. They explain the role of intermediate energy carriers to the production of ATP molecules. They describe the relationship of electron transport system to...

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

Students explore how rechargeable batteries work by conducting a series of experiments. In this physics instructional activity, students discuss the benefits of using rechargeable batteries over disposable ones. They build their own...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your...

Seventh graders look up pictures of viruses or pictures of models of viruses. Using pipe cleaners, beads, Styrofoam or other available materials make models of these shapes. They then observe a demonstration to show the effect of Tobacco...

In this molecules worksheet, students read a 1 page article on molecules and then answer 10 true or false, multiple choice, short answer and/or fill in the blank questions referring to the article.

Students record information and write journal entries on the structure and function of cell organelles while viewing a Powerpoint presentation.

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of...

Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

If you need a clarification of the electron transport chain for your pupils, then this slide show will be a great help. There are nice images of the membranes and elaborations of chemiosmosis which will provide learners support with...

Students are introduced to the process of photosynthesis. In groups, they test the effects of the lack of sunlight on plant leaves and compare the results with their hypothesis. They note the characteristics that plants and animals share...

Open this lesson by reading together about primary and secondary batteries (such as nickel-cadmium cells), problems they can cause in the environment, and how humans can minimize the damage. Afterward, little ones examine a collection of...

Colorful pictures and graphics make this a visually-appealing presentation on animal nutrition. Be aware that two of the sixteen slides include blank graphic organizers, so you will need to find the other existing version of this...

Students investigate the similarities and differences of living things. Specifically, students will be able to identify the life processes of photosynthesis and describe the basic needs of plants.

This PowerPoint includes a game with ocean graphics in which two teams answer increasingly difficult questions about animals. Topics covered include plant and animal cells, animal adaptation, and similarities and differences between...

Students define aerobic and anaerobic respiration. They compare and contrast the processes of aerobic and anaerobic respiration. Students identify organisms that use the processes of aerobic and anaerobic to synthesize energy from food.

How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...

Out of all animals, elephants alone lack the ability to jump. Scholars learn all about animals using a presentation full of fun examples. It describes different types of animals, the biological similarities and differences between...

For as small as they are, there sure is a lot of information for young scientists to learn about bacteria. Help simplify the subject with this instructional presentation that explores the structure, nutrition, and reproduction of...

In this history of life worksheet, students review 4 vocabulary words associated with the beginnings of life. Students place these terms into a crossword puzzle and then complete 2 fill in the blank questions.
