Explains how a spring scale works and what it is used for.

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...

Definition and explanation of a weighing scale. Includes balances, spring scales, hydraulic scales, and electronic scales.

Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By...

Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the...

Students learn about weight by building a spring scale and observing how it responds to objects with different masses.

Students further their understanding of the engineering design process (EDP) while being introduced to assistive technology devices and biomedical engineering. They are given a fictional client statement and are tasked to follow the...

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

In the first of two lessons of this curricular unit, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Student teams use spring scales to drag objects, such as a ceramic...

With a simple demonstration activity, students are introduced to the concept of friction as a force that impedes motion when two surfaces are in contact. Then, in the Associated Activity (Sliding and Stuttering), they work in teams to...

Students' use force sensors to investigate forces and learn about force as a vector. Similar concept to the common "spring scale" force vector lab, but with a real-world twist.

In this lesson plan young scholars experience friction by sliding a block of wood over sandpaper. Students will experiment with frictional forces by measuring with spring scales or rubberbands.

This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.

This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics. It is intended to provide hands-on activities to teach the overarching concept of energy, as it relates to...

On this site you will find the application to the National Park Service to include the Bagg Bonanza Farm as a National Landmark. The first part describes what is found on the land now, but if you'll scroll through the history of...
