Lab #6.3b Mechanics: Chapter 6  the Weight
Lab #6.3b Mechanics: Chapter 6 the Weight

Purpose In this activity, you will investigate the relationship between weight and mass. Discussion Mass and weight are different quantities. Mass is a measure of an object's inertia, the extent to which an object resists changes to its state of...

Wave Motion
Wave Motion

It’s the “wow” when kids realize the demo isn’t just entertainment…“We can’t drill to the center of the Earth, so how do we know about its crust, mantle, inner and outer core? How can we find the epicenter of an...

Lab #6.3a Mechanics: Chapter 6  Putting the Force Before the Cart
Lab #6.3a Mechanics: Chapter 6 Putting the Force Before the Cart

Purpose In this activity, you will observe the motion of a variety of objects under a variety of conditions. You will interpret your observations to learn the relationship between force, mass, and acceleration. Discussion Some of the most fundamental laws...

Pulleys: Fixed, Movable and Systems
Pulleys: Fixed, Movable and Systems

Students construct a complex system of six pulleys and determine its ideal mechanical advantage. They then use the system to lift a weight and measure the work input and energy output of the system. They calculate the actual mechanical advantage...

Quantum Energies Lab Inquiry
Quantum Energies Lab Inquiry

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...

Lab #5.5 Mechanics: Chapter 5  The Big BB Race
Lab #5.5 Mechanics: Chapter 5 The Big BB Race

Purpose In this activity, you will compare the path of a projectile launched horizontally with that of an object in free fall.DiscussionSuppose a ball bearing (BB) were launched horizontally at the same time another BB were dropped from the same...

Lab #4.7 Mechanics: Chapter 4  Sonic Ranger
Lab #4.7 Mechanics: Chapter 4 Sonic Ranger

Purpose In this activity, you will use graphs to investigate motion. The graphs will represent your own motion and will be drawn by the computer as you move. Discussion Graphs can be used to represent motion. For example, if you...

Conservation of Energy: Racing Marbles
Conservation of Energy: Racing Marbles

A marble will roll on different paths, starting and ending at the same height. Students will predict and then measure the final velocities of the marble. Ramp A is the nearly horizontal ramp, and Ramp B dips down in the...

Heat Transfer Radiation
Heat Transfer Radiation

Radiant heat travels in the form of waves. No physical contact between objects is needed to transfer heat by radiation. Students will fill black, white, and silver cans with water, and observe the temperature change in the water when the...

Tornado in a Bottle Inquiry
Tornado in a Bottle Inquiry

Tornado in a Bottle InquiryWe will use funnels, soda bottles, and a toy called a Tornado Tube to explore the concepts of moment of inertia, rotational motion, angular momentum, kinetic and potential energy, and air pressure in an attempt to...

Horizontal Projectile
Horizontal Projectile

Students will use a simple method, employing just a meter stick and stopwatch, to determine the initial velocity of a horizontal projectile. They will then predict the range of the projectile, precisely measure the actual range by using carbon paper,...

Heat Transfer
Heat Transfer

Ice Melting Blocks! Heat can be transferred by conduction, convection, or radiation. In this experiment, students will discover the different rates at which materials can conduct heat. Aluminum is a better conductor of heat than high-density foam. Download Teacher Notes...
