Less than $5 7th Grade Physics Laboratory (by date, latest first)

One "mini" lab that will help students observe and make connections that energy cannot be created or destroyed.

These short activities reinforce or introduce concepts to students. I call these activities “mini labs” because they are simple activities that do not take the whole class period. They are also activities that are safe for use in the classroom and do not have to be done in a lab or with any specialty equipment or materials.

Materials Needed

• 1-1.5 m length of string
• Pencil with an eraser
• Meter stick
• Level
• Pendulum Bob (I have substituted a fishing weight or mass with a hook when I did not have these available in my lab)
• Nail or hook above whiteboard (A 3M hook is great for this, no tools needed to install and does not hurt the walls!
• Whiteboard/Chalkboard (I have also used large sheets of paper on the wall for multiple stations)

For Middle School this supports or extends NGSS: MS PS3-5

For High School this supports MS PS2-2

Engage your students with this lab experience designed to investigate mass, weight and calculating W=mg. This resource is a great way to practice the skills of measuring mass and weight, noting the difference in the measurements, calculating W=mg and connecting the relationship between mass and weight. 

This resource covers

• Making Predictions About Outcomes
• Using Measuring Tools - Triple Beam Balance/Scale and Spring Scale
• Measuring Mass
• Measuring Weight
• Calculating W=mg
• Comparing Calculated vs. Measured Values

Not every student needs the same support! This resource comes with 2 different student recording sheets. One to help learners that need more support and another for more independent students.

Includes:

• Teacher Guide
• 2 Versions of the Student Procedures and Answer Sheet
• Answer Keys
• BONUS Extension Activity: Acceleration Due to Gravity On Other Planets Research

Materials Needed:

• Triple Beam Balance or Digital Scale
• Spring Scale
• Several small objects of different masses
• Calculator
