Angular Rotation Game

Submitted by PocketLab on Fri, 06/02/2017 - 18:43

Exploration

Angular velocity is the rate of rotation of an object along a specific axes. For example, the blades of a ceiling fan rotate around the fan’s central axis. Angular velocity is often measured in the number of degrees the object rotates every second (°/sec) or the number of complete revolutions every minute (RPM). The PocketLab’s gyroscope measures the angular velocity of the PocketLab about the x-, y-, and z-axis.

Soup Can Race

Submitted by PocketLab on Fri, 06/02/2017 - 18:39

Exploration

When two cans of different geometries are released from rest at the same time at the top of an inclined plane the results of the race may not be what you predict. The moment of inertia of each soup can will affect whether it reaches the end of the inclined plane first.

Objective

In this experiment, students will:
1. Determine the order in which each can will reach the bottom of the ramp first and explain why in terms of the energy in the system and the moment of inertia in each can.

Intro to Angular Velocity

Submitted by PocketLab on Fri, 06/02/2017 - 18:24

Exploration

We have previously learned that velocity is an object’s rate of change in displacement. Velocity is often measured as meters/second. Angular velocity however, measures the rate of change in the displacement of an object as it moves around a central point.

Pressure and Volume with a Syringe

Submitted by PocketLab on Fri, 06/02/2017 - 18:11

Exploration 

Explore air pressure and how it works. In a sealed syringe, as the plunger moves back and forth, the volume of air in the syringe changes. With a large enough syringe, a PocketLab can be placed inside to measure the change in pressure as the the volume changes.

Objective

In this experiment, students will:
1. Determine the relationship between air pressure and volume using a syringe.
2. Explore what is happening to the air molecules when there is a greater or less air pressure.

Ceiling Fan in Winter

Submitted by PocketLab on Fri, 06/02/2017 - 18:08

Exploration

When it is cold outside, it is often thought that fans aren’t needed. However, it may be that a fan can bring warm air near the ceiling down to floor level, increasing comfort without raising the thermostat. Energy could therefore be saved.

Objective

In this experiment, students will:
1) Determine how a ceiling fan affects the temperature in a room, both near the floor and near the ceiling.

Saving Energy with Curtains

Submitted by PocketLab on Fri, 06/02/2017 - 18:04

Exploration

Does closing blinds or curtains save energy? Often the blinds or curtains in a room are left open when it is cold outside, even when no one is using the room. Would closing them save energy?

Objective

In this experiment, students will:
1. Determine how to use curtains to save energy when it is cold outside.

What is temperature?

Submitted by PocketLab on Fri, 06/02/2017 - 18:02

Exploration

What does it mean to change temperature? What is temperature? We know what it means to be hot or cold, but what does it mean when you measure the temperature of an item?

Objective

In this experiment, students will:
1. Understand how the temperature of the water is related to the movement (kinetic energy) of the water molecules.
2. Use observations to describe the principle of thermal expansion.

Take a hike!

Submitted by PocketLab on Fri, 06/02/2017 - 17:51

Exploration 

As a hiker changes elevation during a hike, the atmospheric pressure will change. The air pressure at sea level, is vastly different than the air pressure at the top of a mountain. In some regions, it can be even be difficult for people who are not from that region to breathe, because they are not used to the changes in altitude. Using PocketLab, determine the relationship between elevation and air pressure.

Objective

Measuring Weight Using PocketLab

Submitted by PocketLab on Fri, 06/02/2017 - 17:28

Exploration

Barometric pressure is the pressure from the force or weight of air exerted on a surface. The PocketLab’s barometric pressure sensor measures the force of the air molecules that push against the sensor.

Objective

In this exploration, students will:
1. Use the barometer to measure the weight of different objects.
2. Observe how pressure (force) inside a plastic bag is affected when weight is added to the plastic bag.

Use Ratios and Proportions with PocketLab

Submitted by PocketLab on Fri, 06/02/2017 - 16:56

Exploration

Barometric pressure is the pressure from the force or weight of air exerted on a surface. The PocketLab’s barometric pressure sensor measures the force of the air molecules that push against the sensor

Objective

In this investigation students will:
1. Design a system that uses PocketLab’s barometer and an understanding of ratios and proportions to build a scale.
2. Use the given supplies to find the weight of unknown objects.
