Spinning eggs and Newton's first law of motion, yes it's true. This really well done clip is perfect of class or homeschool use. It uses the example of a cooked vs. an uncooked egg to describe Newton's first law. Lots of light bulbs will...

A random sequence of events are recorded, then shown very slowly (with added emphasis). From a water balloon popping to a slap in the face, see exactly what happens at each stage of an event when it is slowed down enormously. Great for a...

How cool would it be to build a trebuchet 1/40th the size of one that would have been used to knock down a castle wall? Build this project with middle or high schoolers at any level (varying the information provided for each), and have a...

Students design a roller coaster and demonstrate their knowledge of Potential and Kinetic Energy. They determine the average velocity a given marble travels on their roller coaster and apply their knowledge of various measurement systems...

Young scientists investigate the scientific concepts and principles that help make common toys such as hula hoops, yo-yos, slinkies, and silly putty work. As a class, they read "Backyard Rocket Science, Served Wet" to get a look behind...

Middle schoolers conduct a series of experiments on conservation of energy and momentum. In this physics lesson, students investigate the factors affecting the period of the pendulum. They build a roller coaster and calculate the...

Scientific method, linear measurements, friction, inertia. Imagine learning scientific vocabulary in an ELA class. Before researching and developing a presentation about simple machines, class members build a common, but decidedly...

Here is a physics lesson that your 5th graders should love. They explore the physics behind roller coasters by viewing roller coaster simulations online. Then, they work in pairs in order to design their own roller coasters and track....

Twelfth graders perform dihybrid crosses and calculate phenotype and genotype ratios. In this series of science lessons, 12th graders explain the process of anodizing aluminum. They research on the benefits and harm caused by resonance...

Designed for a lower elementary school classroom, this presentation on simple machines is a wonderful way to introduce this topic. The resource begins by identifying and defining the six types of simple machines, and then goes on to...

An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...

Now this is a very good demonstration of the Doppler Effect and how it works. A police car with its siren blazing is filmed as it travels closer and then farther away. The effect is explained through text and an illustration. Good video.

A female narrator takes your class on a journey through the history of atomic theory. Not only are protons, neutrons, and electrons introduced but quarks and leptons are too. You will find this most appropriate for viewing in a high...

Sal defines and explains the premise of Hubble's Law and then uses trigonometry to show the relationship between velocity and distance. He explains that as the universe expands, objects get farther away from each other; as objects move...

Parallax is the apparent change of an object determined by the line of sight. Sal defines the concept of parallax and applies it to how we determine the relative distance between us and near-by stars. He draws a diagram to illustrate...

Help learners understand terminal velocity, gravity, and a basic concept of physics. Drag, air resistance, and force are described with excellent examples and easy to follow narration. Compose a worksheet containing key vocabulary...

This is the first clip in a two-part series on Newton's First Law of Motion. Excellent examples and comprehensive explanations truly describe this law of motion. View part two for even more good teaching.

The Theory of Relativity in just five minutes? Yes, and it actually makes sense! A great video, with wonderful analogous examples describing Einstein's famous Theory of Relativity. Comprehensive visuals and narration make this perfect...

With the understanding of space-time and fourth dimensional space comes the question of time travel and free will. The physics of time-travel and time relativity is well explained by leading physicists. This is a highly theoretical...

The conclusion of this excellent four-part series brings modern quantum mechanics and theoretical physics into the conversation of time. Coming full circle from the music employed as an allegory of time, we return to the piano,...

Mostly what you will find here is a history of quantum mechanics. Influential scientists are introduced (along with some of their recorded quotes), the progression of atomic models is reviewed, and finally experssions and equations are...

This is an information-intense presentation for any science class you might be teaching that will study ionising radiation. The material is specific to cancer diagnosis and treatment, and one of the forty-two slides also touches on using...

Sure to be a hit with your charges, here is a science lesson that has lots of hands-on activities packed into it. The focus is simple machines, and how they help us perform work. After a discussion and demonstration session, groups of...

Quiz those kids to assess what they've gleaned from your last lesson on Newton's laws of motion. There are 10 questions that have learners define force, acceleration, velocity, and speed. A bonus question has them write a motion story...
