Concussions are a common sports injury. After reviewing Newton’s laws of motion, force diagrams, momentum, and elastic and inelastic collisions, students will test various materials that might protect the head from sports collisions and use those materials to design protective headgear.

Scientists would like to breed cats that don’t trigger allergies in people. By constructing and analyzing a Punnett square for two low-allergen cats, students will review key concepts including patterns and probabilities of inheritance, genotype, phenotype, genes, alleles, chromosomes and mutations.

In this activity, students will analyze infrared images and then explore how infrared imaging is used across a range of fields of work. Skills include researching, evaluating, synthesizing and presenting information.

Students will use decibel meters to understand how the volume of a sound changes as it travels away from a source. Concepts covered include sound waves, the inverse square law, absorption and reflection. The activity also asks students to consider how the characteristics of a space affect the sound.

Students will explore how our sense of smell helps us interpret the world around us, and how those interpretations may vary. Students will practice analyzing data and determine how temperature affects vapor pressure and thus the intensity of scents.

Students will practice analyzing and graphing data about the moon’s orbit. The activity will help students understand the Earth-moon system and the nature of elliptical orbits.

In this activity, students will research important fossil sites across the world and synthesize what they find into a story to present to the class.

This activity covers where carbon is stored in the Earth, how carbon moves through Earth’s various spheres and how humans are impacting that carbon flow.

With inspiration from the SN 10 scientists, students will explore how their own interests combined with collaboration with a partner can lead to a specific science research question.

Students will practice designing an integrated circuit that can accomplish a simple task. The activity will help students understand that digital circuits are composed of logic gates made up of transistors.

Students will practice making predictions and drawing conclusions. The activity will help students understand how infections spread, especially among organisms living in close proximity.

Students will use a PhET Interactive Simulation to understand the definitions, similarities and differences of elements, ions and isotopes. Then students will explore the Science News journalism archive to find current science research examples that apply these concepts.
