Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Eukaryotes include humans, animals, and plants. Scholars learn about the parts of eukaryotic cells. They design models of a store and match the correct function of each part to the function of a part of the cell. They review their...

Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom...

Learners roll dice in order to simulate the probability of locating an electron in a certain region around the nucleus.

What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...

Build learning by breaking atoms! Young scientists study the way energy changes with a hands-on activity. As they roll steel marbles down a ramp, learners test the hypothesis that kinetic energy does not go away with friction...

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

Students explore scientific theories and the works of scientists.  In this chemistry lesson students develop a timeline  that shows how scientists work was built on the ones before them. 

Young scholars use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs....

Learners observe slides of cork cells and discuss the use of microscopes. They view a power point presentation on "Looking Inside Cells" and take notes aligned with the PPT presentation. They collaborate with a partner to create an...

Why are we here? Well, if you happen to be a Golgi body, the answer is simple! Young biologists embark upon a journey through the tiny world of cellular organelles with an engaging lesson from the K20 Center. The activities open with an...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about...

Incorporate multiple facets of the cell into your next high school lab! Through an introduction to cell organelles, class members observe each cell type and draw visuals to further demonstrate understanding of cellular processes in both...

High schoolers plot particle sizes of common airborne materials on a log scale. They read an article on particle size and its relationship to the ability to pass through the lungs, into the bloodstream, and eventually into the cells...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Chemsitry aces learn that protons are located in the nucleus and the number of protons in the nucleus determines the atomic number of an element. In this lesson, they compare materials made up of a single element and other materials...
