In this video segment adapted from ZOOM, the cast investigates how the pitch of sound changes when they strike a variety of glasses filled with different amounts and types of liquids.
Can a fresh lemon power a digital clock? In this video segment adapted from ZOOM, the cast shows you how this can be done and, in the process, discover how kids can be a part of an electric circuit.
Without certain species, ecosystems would crumble. In this amazing tour, explore keystone species around the world and how they help to maintain ecosystems around the world.
Students will observe/investigate the movement of water through the different stages of the water cycle and determine what drives this cycle. Students are asked to think about what precipitation is then watch a video about why the water cycle is important. They observe a simple version of the water cycle and take some notes. Students are asked what stages require solar radiation, which require water to give off heat, and which are driven by the force of gravity. The teacher does several different demonstrations while students fill in a sheet that has the students recording their observations of different processes in the water cycle and how energy is involved. Students build their understanding of the water cycle through the different models that are shown or experienced. The culminating activity has them create their own model of the water cycle from the viewpoint of a water molecule including the processes, the energy involved, and gravity.
Join Tarissa and Sabrina as they measure and compare the volume of different sounds across New York City in this video from DragonflyTV.
Play with a bar magnet and coils to learn about Faraday's law. Move a bar magnet near one or two coils to make a light bulb glow. View the magnetic field lines. A meter shows the direction and magnitude of the current. View the magnetic field lines or use a meter to show the direction and magnitude of the current. You can also play with electromagnets, generators and transformers!
Investigate Faraday's law and how a changing magnetic flux can produce a flow of electricity! Best used as a demonstration and not a full lesson.
Light a light bulb by waving a magnet. This demonstration of Faraday's Law shows you how to reduce your power bill at the expense of your grocery bill.
The CyberSquad tests which broom can travel the furthest in five seconds in this video from Cyberchase.
In this video segment from Cyberchase, through addition and regrouping in base sixty, Matt helps Digit figure out what time his CyberSoufflŰ__ŰÖ will be done.
This activity is designed to be used with the Feature Story, A Whale of an Ocean, and students in grades 4-5. After reading the text, students work in pairs to match questions and answers posted around the classroom. The PDF document includes questions and answers, directions, and an answer key.
In this video segment from Cyberchase, Harry decides to train as a firefighter and uses line graphs to chart his physical fitness progress.
This informational text discusses the unique property of ice - that it floats in liquid water. Students focus on real-world examples and how ice is necessary for life in the polar regions. The text is written at a kindergarten through grade one reading level. This is a PDF containing the informational text and a glossary.
Explore pressure in the atmosphere and underwater. Reshape a pipe to see how it changes fluid flow speed. Experiment with a leaky water tower to see how the height and water level determine the water trajectory.
The is a google sites learning hub all about force and motion. There are different activities that cover what force is, pushing and pulling, and simple machines. There is also a fun activity to learn about some famous scientist (some of whom contributed to the knowledge we have of force). Activities included use google earth, google forms, google slides, and other google tools.
The goal of this lesson is to assist students to relate the forces acting upon particular objects and the “unseen” resolution of those forces. The video begins with a story line involving Adam, who helps his father in the garden by disposing of a garbage bag of leaves—the very act that involves resolution of forces. This lesson includes embedded video clips, animations, diagrams and inquiry-based experiments where students are required to work collaboratively and answer thought-provoking questions. The experiments will involve the study of the resolution of forces on objects placed on varying planes or on platforms of different angles, using materials that are easily found. Finally, students are required to discuss and apply what they have learned to determine whether it is easier to push or to pull a luggage bag with wheels. The lesson will take about 50 minutes to complete.
Students will conduct a number of investigations involving density and buoyancy to understand the forces applied to objects and the resulting interactions among them.
Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.
