High schoolers assess and explore gravity in the Universe via several short video lessons. They analyze why this science matters and the history of Sir Isaac Newton's law of gravity. A variety of questions are asked within this...

Students use the reaction time to figure out problems. They use the following example to get them started with reaction time: the edge of a ruler is placed near a person's thumb and index finger and, without warning, the ruler is...

Learners calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to measure...

Students investigate different forces and draw arrows to signify specific directions of force. Students are then shown a brick and they are asked to draw a diagram which will include labels for the forces that are acting on the brick....

Seventh graders identify the factors that determine the strength of the friction forces when two objects push against each other. Describing the difference between weight and mass, they participate in experiments. They state the law of...

Students write a sketch of an artist or athlete that has pushed the limits on gravity. They explore concepts of rhythm, balance and friction. They examine how engineers design sports equipment.

Students observe examples of gravity, friction, and force on the playground. They then experiment and participate in a variety of activities in centers back in the classroom.

Students role-play the jobs of space shuttle astronauts, conduct experiments, and research space using the Internet and offline experiments. Student-astronauts hold a "press conference" to share their information with others in a...

Eighth graders engage in an experiment which uses an inclined plane and balls of various masses to determine the effect a large object has on a small object. They study velocity, momentum, gravity and forces.

Students see that light and heavy objects fall at the same rate, as established experimentally by Galileo. They see that falling objects, and balls rolling down an incline, tend to accelerate at a constant rate a. Their velocity...

Students, by way of the Olympic Games event of ice skating, are introduced to the concepts of gravity. They try some hands-on gravity experiments and explore the concept of gravity through art.

Students use a coffee cup to demonstrate weightlessness. After a lecture/demo, students read an article on free-fall. They perform a simple experiment which helps them explain the concept of weightlessness.

Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Students read and discuss the book about the butterfly and create their own butterflies using liquid watercolors and pipe cleaners. They then create a butterfly development book, included in the lesson, and color the pictures using...

Students observe falling objects. They discover the rate of falling is based on air resistance and not the weight of the objects. They discuss how engineers use this type of information to design aerodynamic shapes.

Third graders demonstrate that gravity is a force.

Eighth graders use Newton's Laws of Motion to assist a troop in making a winning car in the Pine Wood Derby.

Tenth graders devise a computational model to explore how the orbit of the Earth might change if its velocity were different. Using accurately recorded data, 10th graders defend a scientific argument.
