Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Use this during the season of teaching about the seasons! As Earth revolves around the sun, its tilt causes the weather to change. The graphics in this presentation show how Earth's position in space has an effect on the angle of...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

The universe is full of sources of energy. Explore the energy of pulsars with your classes through a simulation. An interactive lesson allows learners to manipulate the angle of rotation of both the earth and the pulsars. A real-time...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Why does Earth experience summer, fall, winter, and spring? Using an informative demonstration, learners see how the angle of the sun on Earth and the rotation of Earth determine the seasons. Scholars work in pairs to learn that the...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...

Why do many tightrope walkers use a balancing pole? The simulation explores the benefits of balancing poles and the features that are most important. Pupils control the pole length, pole mass, pole stiffness, and the initial angle of...

The University of Hawaii has published a vast collection of midterm and final exams for their Physics 152 course. This particular exam offers a variety of assessment methods, and covers the topic of electromagnetic radiation....

Young scholars conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.

The climate at the equator is hotter than the climate at the poles, but why? The lesson goes in depth, explaining how the angles of illumination relate to the heating rate at different latitudes and seasons. Scholars use a strong lamp,...

Why do we have four seasons? A series of questions about the Earth's orbit and its impact on seasons challenge Earth science students.The second page of the resource has nine multiple choice questions, such as "One year on Earth is one...

Winter, spring, summer, and fall—take the learning of the seasons beyond the elementary level to the middle school classroom. Curious learners begin by watching videos about the seasons and the rotation of planet Earth. Then,...

In molecules, bonds rotate about the nucleus due to the repulsion of subatomic particles. In a simulation, learners manipulate the bonds of a molecule to meet the atoms' needs. They can then see the specific molecular shapes of five...

Students explore the earth's rotation and phases of the moon. In this planets lesson, students rotate and revolve around a light representing the sun. Students use movement and props to simulate what causes the phases of the moon as well...

In this frames of reference worksheet, students solve 5 problems given the details of a journey an ant takes from the center of a CD ROM to its edge. Students draw a scaled sketch of the turntable showing the motion of the ant from...

Students explain why compass angles need to be corrected for regional magnetic variation. They observe the difference between magnetic and true north. Each student measures the angle of variation for a town in a different state.

Students discover how the Earth's axis of rotation affects the angle of sunlight and the length of day. They take a survey and give the survey out to family members and friends. They tally their findings and then determine the correct...

Students explore how the angle of sunlight affects the Earth's temperature and seasons and then apply this understanding to their local situation.

Students conduct an experiment to observe the response of maize roots when rotated 90 degrees.

Students conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.

How do the hydrophobic and hydrophilic regions of a protein affect its shape? Science scholars explore the molecular properties of protein molecules using a detailed interactive. The resource allows the user to rotate the protein, view...

Young scholars 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.

High schoolers examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.
