Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA...

In this activity, students' will use a force sensor and a motion detector to study the relationship between the force applied to a rubber band and the distance to which it stretches. They will then model force versus strech data with a...

Students must find the value of the amount of stretch that will occur to a spring on another planet.

Students must find the value of the spring constant and the original length of a spring based on data that was collected from stretching a spring different amounts using a force probe.

Students will learn about composite materials, tension as a force and how they act on structural components through the design and testing of a strip of plastic chair webbing.

This lab is designed to have students discover the relationship between the work that is done and the stretch of a spring. Students will get the area under a Force/Stretch graph to find the work given to a spring for a given situation....

Students use balloons (a polymer) to explore preconditioning a viscoelastic material behavior that is important to understand when designing biomedical devices. They improve their understanding of preconditioning by measuring the force...

An interactive simulation that teaches about force and potential energy by changing variables to stretch and compress springs. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

Stretch and compress springs to explore the relationships between force, spring constant, displacement, and potential energy. Investigate what happens when two springs are connected in series and parallel.

[Free Registration/Login Required] This unit gives children experience of forces including attraction and repulsion between magnets, compression and stretching of springs, and stretching of elastic bands. They learn that these forces...

To learn how friction affects motion, students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces...

Hooke's law says that the opposing force of a spring is directly proportional to the amount by which the spring is stretched. How accurately Hooke's law describe the behavior of real springs? Can springs be used to make accurate scales...

In this activity, students study Hooke's Law. They understand that stretch on a spring is directly proportional to the force applied to the end of the string. Students observe a spring being stretched as candies are added to a cup...

Activity 1 of this module investigates: How does potential energy change when things are pushed or pulled? Exploring how force is related to potential energy, this activity investigates how potential energy is changed when a spring is...

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.
