Measuring Forced Vital Capacity with PocketLab Spirometer

Submitted by PocketLab on Fri, 06/02/2017 - 16:53

Exploration

A spirometer is an apparatus often used in the medical field to find the cause of shortness of breath. A spirometer can rule out lung diseases like asthma, bronchitis, and emphysema. A spirometer can measure forced vital capacity. Forced vital capacity is the amount of air exhaled during a forced breath. Explore what factors affect forced vital capacity.

Measuring Pressure Change from Chemical Reaction

Submitted by PocketLab on Fri, 06/02/2017 - 16:49

Exploration

After a change occurs, if the molecules of the chemicals involved do not change, it is only a physical change. Ice melting to water is an example of this. A change has occurred, but the H2 0 as ice, remains H2 0 as water. If however the molecules of the chemicals involved do change to form new chemicals, then a chemical change has occurred.

Pressure and Volume with a Syringe and Flask

Submitted by PocketLab on Fri, 06/02/2017 - 16:44

Exploration

Explore air pressure, temperature, and volume and how they work together. In a syringe sealed to an Erlenmeyer flask , when the syringe’s plunger moves back and forth, the volume of air in the syringe and f ask changes. Will the pressure also change if the temperature of the air sealed in the syringe and f ask changes? A PocketLab can be placed inside the Erlenmeyer f ask to measure the change in pressure as the the volume and temperature change.

PocketLab Bungee Jumper

Submitted by PocketLab on Fri, 06/02/2017 - 16:38

Exploration

A bungee jumper leaps from a tall structure and falls toward the ground. The bungee cord begins to stretch and transfers the kinetic energy of the fall into elastic potential energy, slowing the jumper to a stop.The cord then pulls him/her back up as the elastic potential energy turns back into kinetic energy. The jumper then oscillates up and down until their energy is completely dissipated.

Simple Pendulum Motion

Submitted by PocketLab on Fri, 06/02/2017 - 16:34

Exploration

A simple pendulum consists of a mass, m, hanging from a string of length, L, and fixed at a pivot point, P. When displaced from equilibrium and to an initial angle (amplitude, θ) and released, the motion will be regular and repeat. This is an example of periodic motion.

Magnetic Minesweeper

Submitted by PocketLab on Thu, 06/01/2017 - 19:37

Exploration

In the Magnetic Minesweeper Lab, you will recreate the classic computer game Minesweeper in real life! Using PocketLab’s magnetometer, you will try to discover hidden mines and mark their locations on a grid. You can do this lab with two people to create a Minesweeper competition. One partner hides mines in different grid locations while the other partner tries to locate the mines to not get blown up!

How does distance affect the strength of a magnetic field?

Submitted by PocketLab on Thu, 06/01/2017 - 19:31

Exploration

Can you throw a baseball without touching it? No, your hand needs to push the baseball forward as your throw it. Objects often interact like this, through contact. The baseball will then stop moving after contacting the ground or a catcher’s mitt. But can two objects interact when they aren’t in contact, when they are instead, at a distance from each other? Using PocketLab, you can explore how this might be possible.

Magnetic Field in a Slinky

Submitted by PocketLab on Thu, 06/01/2017 - 19:27

Exploration

Until the late 1800’s, electricity and magnetism were regarded as separate forces. A number of scientists, including Michael Faraday and James Clerk Maxwell, made important discoveries which led to our current understanding of electricity and magnetism. The interaction between positive and negative charges is, in fact, one force, the electromagnetic force, which results in both electrical currents and magnetic fields.

Projectile Motion of an Object

Submitted by PocketLab on Thu, 06/01/2017 - 19:22

Exploration

When an object is in free fall, the only force acting on the object is gravity. In general terms, an object moving upward is not considered “falling,” however, if gravity is the only force acting on the object (air resistance being negligible) then the object is in fact in a state of free fall. The projectile motion of an object is the trajectory of an object in free fall near Earth’s surface after being thrown or launched in the air. The curved path of the projectile is under the effect of gravity only after being launched.

Introduction to Free Falling Objects

Galileo Galilei is often considered one of the founders of modern science. This is because he investigated questions through experimentation and observations. One of his most famous experiments involved dropping cannonballs of different mass to determine whether they would accelerate to the ground at different rates.
