Without structure, there wouldn't be function. Scholars examine the meaning of structure and function with a hands-on experience. Using balls from different sports, they compare and contrast their structures and then analyze how each...

You know you taught it, but did they learn it!?! A quick formative assessment asks pupils to describe both photosynthesis and cellular respiration before showing how they relate to each other. The lesson marks the 20th lesson in a...

A system is only as good as the sum of its parts! Young scholars explore the components of the different body systems using a hands-on lesson. The lesson helps learners build an understanding that there is a hierarchy of components in...

Teamwork makes the dream work! A well-designed lesson helps learners discover how the circulatory and respiratory systems team up to keep their bodies alive. The lesson includes a diagram of the major connections between the lungs and...

Students explore the circulatory system. They participate in media activities to explore blood flow and identify the parts of the circulatory sytem. Students create a model of the circulatory system.

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Young scholars are introduced to the life cycle of a cell. In groups, they identify and describe the function of organelles. They compare and contrast the differences and similarities between plant and animal cells as well. They complete...

Students learn about cells. In this cells lesson plan, students take several days to learn about plant and animal cells and make their own edible cells with a cookie and icing.

Students will be able to identify the different stages of the eukaryotic cell cycle as well as the different stages of mitosis in the proper order. Students will also be able to recognize what organelles of the cell are integral to...

Sixth graders review how and which plants operate in terrariums. In groups, they follow instructions to make their own terrarium and place different types of plants in it. To end the lesson, they review the steps in the water cycle and...

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...

Students show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity in order...

Ninth graders share what they know about cells. In this biology lesson, 9th graders study different microscopic images of the cell. They draw one and explain to their partner why they chose that image.

Fifth graders gather information about plant cells. As they read in their science book about plant cells, they take notes on the important facts. Then, they look at their notes and organize them into an outline before they write their...

Learners observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

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

Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

Did you know that meat tenderizers contain DNA cutting enzimes? Did you know that you can isolate your own DNA? Or the DNA of fruit? Explore with your learners the DNA world with a series of experiments using readily available materials...

In this evolution worksheet, students unscramble 9 vocabulary terms to solve a clue as well as complete 8 other riddles and word scrambles about evolution vocabulary.

Students are introduced to genetics along with genetic diseases and heredity. In groups, they complete a Punnett Square to determine the dominant and recessive genes. After viewing diagrams, they identify the characteristics of DNA and...

Even though the presentation is connected to a particular textbook, it could be used in any lower elementary classroom to review plants. There are diagrams and colorful graphics that make it attractive and engaging.

Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.

All of the people in your class would agree that life would be different without the invention of the telephone! Study Alexander Graham Bell's most famous and influential invention through the primary source document of his...
