# Measurement & Analysis

Arbor Scientific is providing physics and physical science teachers with a collection of student lab activities for the development of measurement and analysis skills. Here you can browse lab activities by title and get teachers notes, student worksheets and a list of equipment and supplies needed for each activity.

• ## Density Rods

Posted on January 1, 2011 by Arbor Scientific

The Density Rod Set consists of two rods. The aluminum rod sinks in warm water and floats in cool. This is because cool water is more dense than warm, and the aluminum rod is made to be between those two densities. The PVC rod does the reverse – floats in warm water and sinks in cool. This time, the rod changes more than the water, becoming more dense when it is cool.

• ## Quantum Lab (Inquiry)

Posted on January 1, 2011 by Arbor Scientific

Something that is quantized exists in multiples of a set quantity. Examples are charge [1.6 x 10-19C] or quantum energies of photons. Planck and Einstein predicted that light existed as discrete bundles called photons. Since they could not see a unit of photon energy, this lab constructs a model of how quanta was derived and visualized by scientists. In this INQUIRY lab, students will develop their own method for finding the pennies' mass.

• ## Picture of a Lab: Different Graph Types

Posted on January 1, 2011 by Buzz Putnam

Picture of a Lab – Different Graph Types Station #1 investigates the relationship between force and displacement of a stretched spring. Students will discover a direct linear relationship, with an equation of the form y = mx + b. Station #2 demonstrates Boyle’s Law, or the relationship between the pressure on a gas and its volume. The graph is a hyperbola, y = 1/x. Station #3 relates light intensity to distance from the source. The graph shows an inverse-square relationship, with an equation y = 1/x2. Station #4 uses staggered, stacked blocks to result in a simple parabolic graph, where y = x2.

• ## Density of a Solid

Posted on January 1, 2011 by Arbor Scientific

Regular and irregular objects will be used. Students will devise a way of finding the volume of each object - calculating the volume of a cube or using water displacement for irregular objects. They will calculate the density of each and compare to standard values.

• ## Density of a Liquid

Posted on January 1, 2011 by Arbor Scientific

Measure the mass and volume of a quantity of liquid, and calculate its density. Students will have to account for the container's mass.

• ## Acceleration Force and Mass

Posted on January 1, 2011 by Stephen Rea

Students love fast moving experiments, but higher speeds often require higher technology. That can challenge the budget and students' ability to use the technology. These simple, but highly accurate photogates remove both barriers. No costly computers are needed, and set up is easy. Students literally ‘get up to speed’ fast!
