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.

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.

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...

[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...

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.
