### Description

During this lab students will change three variables on the pendulum- length of string, angle of release, and mass of the bob. They will test and understand the relationship between the variable being tested and the period.

Materials needed for each group: Ring stand (or some way to hang the pendulum), string, hanging masses (or a cup full of pennies, marbles, etc), stopwatch, and a protractor.

Included are 2 versions of this lab:

1. IN PERSON VERSION: This inquiry version in class takes 2 class periods. Day 1 is spent understanding the variables and figuring out relationships, and day 2 is spent collecting data. At the end of day 2 they will either write a conclusion based on their findings or fill out a CER chart.

2. AT HOME VERSION: In this distance-learning version, students will make their own pendulum and collect data. If you are worried about students not having needed materials, a youtube video is included that students can watch and record data from.

Both versions are completely editable!

This is great for a high school physics class or can also be used in any science class to reinforce the scientific method, variables, and understanding why we only change one variable at a time.

NGSSMS-PS3-2
Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system. Emphasis is on relative amounts of potential energy, not on calculations of potential energy. Examples of objects within systems interacting at varying distances could include: the Earth and either a roller coaster cart at varying positions on a hill or objects at varying heights on shelves, changing the direction/orientation of a magnet, and a balloon with static electrical charge being brought closer to a classmate’s hair. Examples of models could include representations, diagrams, pictures, and written descriptions of systems. Assessment is limited to two objects and electric, magnetic, and gravitational interactions.
