In this activity, students will explore two given websites to gather information on Bone Mineral Density and how it is measured. They will also learn about X-rays in general, how they work and their different uses, along with other imaging modalities. They will answer guiding questions as they explore the websites and take a short quiz after to test the knowledge they gained while reading the articles.

In this activity, participants explore the way the shape of the land and the pull of gravity influence how water moves over Earth. By making unique mountain models from crumpled paper and watching how water moves across them, participants can act as Earth scientists, using their observations to make predictions about the future of our planet. Both English and Spanish activity resources are included. Educators should begin with the file named: Paper Mountains - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

This activity allows students to demonstrate their understanding of the Law of Conservation of Energy in the framework of student-designed investigations.

This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

This activity is a classroom and lab investigation of magnetism. Students gather results of experiments involving the forces of magnets. They use this data to develop their own experiments to test properties of magnets.

Using the scientific method this simple hands on experiment is designed to verify Newton's Second Law.

In this introductory physics lab activity, students explore the sounds made by the free-end of a ruler vibrating off the end of a desk.

Students will review their knowledge of tension and focus on tensile loads and failure caused by them.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner. Because of the unique quantities and locations of the materials and the forces that spread them out, each model nebula will be unique—just like each real nebula! Both English and Spanish activity resources are included. Educators should begin with the file named: Nebula Spin Art - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: .

In this activity, participants explore the complex but predictable ways objects in the universe interact with each other. Stars, planets, moons, and other objects in space orbit around each other because of gravity, and NASA scientists can use what we already know about the laws of physics to make new discoveries and predictions. Participants in this activity use orbiting clay balls to make simple, functioning models of interacting objects in space. Both English and Spanish activity resources are included. Educators should begin with the file named: Objects in Motion - Lesson Plan - START HERE.

Estimated time required: 1-2 class periods.

Technology required for this lesson: Tablet or Smartphone.

Join Tarissa and Sabrina as they measure and compare the volume of different sounds across New York City in this video from DragonflyTV.

In this video segment adapted from Interactive NOVA, astronaut John Young experiences extreme temperatures on the Moon that are a result of the Moon's low gravity and lack of atmosphere.

This activity is an extension of the FOSS Variables Lifeboat investigation. Students choose a lifeboats variable to investigate, write up an experiment based on the variable to be tested, test the variable, and create a lifeboats investigation poster to share their results.

This lesson is a presentation of famous scientist throughout history where the students will learn and take notes about the contributions and discoveries made in science.

The CyberSquad tests which broom can travel the furthest in five seconds in this video from Cyberchase.

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.
