Students create a paper model to illustrate sea-floor spreading.

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 build and compare models of both an energy inefficient and efficient classroom. In this energy efficiency lesson, students creatively use recycled materials to build two separate classroom models. They factor in concepts such as...

Life on Earth is made possible by the unique composition of its atmosphere. Working collaboratively, a scale model is created as young scientists learn about the different layers of gas that surround the planet. Cards are included that...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.

In this atomic fingerprint worksheet, students read about the Bohr model and electrons changing energy levels and emitting energy. They answer questions about the atomic spectrum and the fingerprints for specific atoms.

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

Have your young learners work in pairs to find and research an endangered species. They use research to develop ideas about saving their animal from extinction. Pairs develop a three-dimensional model of the animal's habitat. Then,...

Students evaluate data to determine changes in length of day. They model the revolution of Earth around the sun to show changes in length of day and sun angle and illustrate how the sun angle affects the change of season.

Third graders create a model of the solar system. In this solar system lesson, 3rd graders create a scale model of the solar system. Working in pairs students solve mathematical problems to correctly measure the distance each planet is...

In this asteroids activity, students solve six problems where they find the equation for the mass of asteroids, they find the equation for the growth of asteroids, and they integrate their answers.

See what you cannot see by getting a little creative. An intriguing lesson has learners use lasers to explore X-ray diffraction. Given a box with unknown structures, they shine a laser through the box and interpret the results....

How do some viruses spread so quickly, and why do they make us feel terrible? Answer these (and many more) questions through a simple yet impactful lessons. Pupils observe demonstrations that show the two methods viruses use to escape...

In this modeling a planetary nebula activity, students use a diagram to calculate the intensity at different radii from the center of the nebula. Students use the Pythagorean Theorem to determine the distance between two points on the...

Students create a model of centrifugal compressor wheel following step-by-step instructions. In this technology instructional activity, students use SolidWorks to create curved surfaces. They give practical applications of a centrifugal...

Students begin by using clay to model fertilization and early development of sea urchins and chordates. They move on to mixing live sea urchin sperm and ova together to observe, diagram and record events occurring in fertilization and...

Teachers turning into students? It's not Freaky Friday! It's a thoughtful workshop that teaches participants how to plan professional development for staff. Third in a 15-part series, the workshop provides a platform for the other...

Take a deep breath and have your class construct working models of a lung! Using 500ml plastic bottles as the chest cavity, and balloons for the lung and the diaphragm, learners work in groups to make a model. The models help them to...

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Students create and label a model of a lobster.  In this lobster lesson, students become familiar with the parts of a lobster and their functions.  Students display their lobsters in the classroom.

Students design STELLA model based upon scientific research done on monarch butterfly lifecycle; model allows students to predict how many larva will be produced during the winter and thus collect the correct amount of food to sustain...
