In this activity, students are introduced to static equilibrium by learning how forces and torques are balanced in a well-designed engineering structure. A tower crane is presented as a simplified two-dimensional case. Using Popsicle sticks and hot glue, student teams design, build and test a simple tower crane model according to these principles, ending with a team competition.

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.

Working in teams of four, students build tetrahedral kites following specific instructions and using specific materials. They use the basic processes of manufacturing systems – cutting, shaping, forming, conditioning, assembling, joining, finishing, and quality control – to manufacture complete tetrahedral kites within a given time frame. Project evaluation takes into account team efficiency and the quality of the finished product.

In this lesson, students will learn that forces can change the speed or direction of motion. Students will observe what happens to a toy car as it moves down a ramp and then encounters "speed bumps" that are added at different lengths away from the ramp. Students will also add a clay figure to the top of the cars to see what effect the ramp and "speed bumps" will have on the figure.

In this activity, students will build their own catapult to help them understand the concept of force and its effect on an object.

This is designed as a challenging PLTL workshop in calculus-based introductory physics. It may also serve as as module in workshop physics. This is intended to indicate to the student the level of mathematical skill appropriate upon finishing the introductory courses in physics, and to encourage them to reach for this level of mathematical rigor. Text, problem sets, and associated activities are provided.

Students will construct a CD hovercraft and apply Newton's Laws of Motion to make them work. They will also investigate how hovercraft reduce friction, learn how the technology is used in training astronauts for space missions, and design their own hovercraft competitions.

This brief video lesson describes gravity and explains it as a pulling force that draws objects together. Discussion/assessment questions and suggested supplemental resources are also included.

This lesson is the first of a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. In this activity students examine different scientific aspects of hurricanes, all in an effort to begin to understand the nature of motion?particularly how changes in speed or direction of motion are caused by forces.

This lesson is the second in a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. In this activity students? study of hurricanes is broadened by exploring how technology and science are used today to identify, measure, and track powerful tropical storms to better warn and secure people from their often-devastating impact.

Fun learning inquiry labs on Newton's Laws using common materials. Explore the Physics behind cars, rockets, seatbelts, planets, common "magic tricks" and more.

In this activity students will investigate the paths that marbles take once set into motion and then how to change those paths, noting if and how they change.

In this lesson, students will be given objects and asked to make predictions on how far each object will move after they blow in it. Then they will measure the distance and record their observations in their science journals. After their science investigation into motion students will read Move It! by Jaime A. Schroeder to reinforce the hands-on learning activity.

In this physics interactive lecture demonstration, students will observe the constancy of gravity in a variety of different situations. They will predict what will happen if a plastic bottle, filled with water and having a hole near the bottom, is dropped. Will the bottle fall at the same rate as the water inside the bottle?

In this lesson students learn about bond strengths/bond types by observing a demonstration. They apply this knowledge in their own experiments so they can predict bond strengths /bond types based on the locations of the bonding atoms on the periodic table. Students will illustrate the type of bond formed between atoms using 3-D models made from foam balls, toothpicks, rubber bands, and pipe cleaners.

In this interactive lesson, students rotate to different sports activity stations to determine if a push or a pull or both are being used for that sport. Students record their observations by writing a simple phrase to explain the push or pull force they used. At the end of the rotations, students compile their data onto a class tally graph. Extension activities include involving the Olympics and Para-Olympics and their family members. Probing questions that include determining if the age of the thrower affects force and distance and assessment extend and complete the lesson.

This brief video lesson introduces Newton's three laws of motion, using the motion of a bicycle as illustration. Discussion/assessment questions and suggested supplemental resources are also included.

The People's Physics Book v3 is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically

In this lesson, students will observe and record the amount of work done by marbles rolling down a plane and more fully understand the relationship between potential and kinetic energy.

In this interactive second lesson in a two-part series, students explore ramps. They design and create plans for ramps; and then they build, test, evaluate and adjust the make up of the ramps they create to determine the ramp that will allow objects to roll the longest distance. Lesson extensions include probing questions, a Ramp Builders activity sheet, an assessment suggestion and alternative activities using the ramps which include timing the rolling objects, building ramps where items go up, a web link for differentiated learning and real life applcations.
