Lesson Focus

Lab Equipment: Mechanics

Physical Science

You will get to find out what it’s like to work in a real laboratory environment by first exploring an interactive, virtual lab. Learn the basics, from proper safety procedures to the equipment used in the physical sciences, all without any of the hazards or messes of an actual lab.

Now You Know

After completing this tutorial, you will be able to complete the following:

• Explain the purposes of equipment in a mechanics laboratory setup.

Everything You'll Have Covered

What purpose does a 90-degree rod clamp serve in a laboratory?

~ Ninety-degree rod clamps are often used in laboratories to attach two metal rods perpendicular to one another.

How many centimeters and millimeters is a metric ruler usually divided into?

~ Most metric rulers are usually divided into 100 centimeters and 1,000 millimeters.

What was carbon paper originally designed to do and how is it commonly used in laboratories today?

~ Originally, carbon paper was designed to make copies of typed documents. In today's laboratories, it is commonly used to acquire data on an object's motion.

What graduations are indicated by each of the three beams on a triple beam balance?

~ The first beam indicates 100-gram graduations, the second indicates 10-gram graduations, and the third indicates 1-gram graduations.

A rod clamp, metric ruler, trajectory apparatus, carbon paper, triple beam balance, and white craft paper are apparatuses mentioned in the animation. What would you do to demonstrate the use of each of these to another student?

~ To demonstrate the use of the rod clamp, I would place the metal rods in the holes, which are perpendicular to each other, and screw the clamps tight. With the metric ruler, I would measure the length, width, or height of something in meters, centimeters, or millimeters. I would use carbon paper to gather data on an object's linear motion by examining the dots left from sparks that pass through the carbon paper. Additionally, I would use the metric ruler to then measure the distance between the dots left through the carbon paper. I would use the triple beam balance to measure the masses of various objects in grams. I would use the trajectory apparatus to put objects into motion. Finally, I would use the white craft paper to wrap items in the lab or cover books.
