In this interactive activity from ChemThink, take a closer look at atomic structure, properties, and behaviors.
This pathway introduces the building block of all matter, the atom, and some of the key experiments that helped scientists discover the subatomic particles that give atoms their unique properties.
A visual representation of how atomic clocks work
This video segment adapted from A Science Odyssey takes a look at the scale of the atom and the tremendous amount of space between the electrons and the nucleus. If all this empty space exists in matter, how can any substance be solid?
In this activity, students will explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms, as well as the implications of heating or cooling a system. This activity focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.
In this lesson, the students will discover the relationship between an object's mass and the amount of space it takes up (its volume). The students will also learn about the concepts of displacement and density.
We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.
In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.
The impact of natural disasters is made vivid in this video segment adapted from NOVA. A small town in Iceland, prepared for recurrent avalanches, is devastated when one takes a new and damaging path.
Have you ever seen a mobile? These are structures hang from the ceiling and are usually made up of many layers of rods to which differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air.
This lecture/activity on force will further a students' understanding of forces on an object, as well as the difference between a balanced and unbalanced forces.
This activity is a lab investigation where students design a balloon car to collect data about speed and velocity.
Make a balloon powered car out of recycled material
This activity enables students to apply concepts of 'newton's laws of motion' that are learned in class to a realworld situation by having them create a car powered by a deflating balloon that travels as far as possible.
This activity is a hands-on investigation that teaches students that air resitance affects how things move and that pressure from compressed air can move things.
In this structured inquiry activity students will work in groups/ teams to build a balloon rocket of their own design. The rocket will race in one dimension and require that they apply their knowledge of position, time, and velocity.
Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn about volume, buoyancy and density to help them iterate more successful balloon designs.Applying their newfound knowledge, the young engineers build and test balloons that fly carrying small flip cameras that capture aerial images of their school. Students use the aerial footage to draw maps and estimate areas.
CK-12 Basic Physics - Second Edition updates CK-12 Basic Physics and is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically.
In this video from DragonflyTV, Jai and Jonathan track, graph, and analyze the motion of basketball shots as they investigate what factors influence the accuracy of their game.
This video segment describes how the Australopithecus afarensis skeleton known as Lucy could have been fossilized. Footage courtesy of NOVA: "In Search of Human Origins."
