In this experiment, middle school and high school students use their PocketLabs learn about angular velocity -- the rate of change of angular position of a rotating body.
What is a Theremin?
A theremin , named after its Russian inventor in the early 1900's, is an electronic musical instrument that is controlled without any contact by the musician. Volume is controlled by moving one hand near one antenna, while pitch is controlled by moving the other hand near a second antenna. The sound is generated by a pair of high-frequency oscillators.
RC Car Fun!!!
Here is a fun summertime activity! Race an RC car with PocketLab Voyager. Challenge your friends to see who can negotiate a series of cones in the shortest amount of time without hitting any of the cones. Start and end times are obtained by Voyager's magnetometer as the RC car passes by magnets.
What causes the seasons on Earth?
Weather is always changing. Humans have been dividing up the year based on these changes in weather for thousands of years. A division of a year based on weather is called a season. Different regions of the Earth have different names for seasons and different types of seasons. The most common seasonal names used are Winter, Spring, Summer, and Fall.
On a hot, sunny day, would you rather wear dark or light-colored clothes? Have you ever walked across dark pavement barefoot on a hot day? How did that feel? Would you rather walk on the dark pavement or a lighter colored sidewalk along green grass? In this experiment you will investigate how the color of objects can affect it’s temperature.
Objective: The objective of today’s lab is to determine if water or sand heats up more quickly and “keeps” its heat longer. You will then use your collected data to answer the following question: How does a hot, sunny day at the beach affect a fish in the water differently from a crab on the sand? Explain.
The law of conservation of energy states that the total energy of an isolated system remains the same. Over time, all energy is conserved. Energy is neither created nor destroyed – instead it transfers from one form to another. Objects in motion have kinetic energy. Thermal energy is energy in a system due to its temperature.
Engage your students in engineering practices and classic force and motion and energy concepts in a fun and unique way. With a PocketLab attached to a Hot Wheels car and a track full of magnets, you'll be able to collect data on position, velocity, acceleration, and energy as your car zips up an over hills and around loops. Turn your students into theme park engineers and have them design "roller coaster" tracks, iterate on car designs for races, or teach basic concepts on position and velocity. This activity is sure to help engage your students in a meaningful way.
Almost everyone enjoys watching the figure skating events in the Winter Olympic Games! But only a select few worldwide with the required skills and God given talent have the opportunity to compete. What about the rest of us? We can’t even imagine how the Olympians manage to perform all of those fancy quad jumps and camel, layback, upright, and sit spins. But we can sit in a chair, and with the right chair, we too can do a sit spin of sorts! Add PocketLab and we can also learn some physics about conservation of angular momentum.
Have you ever wondered what your dog does all day long while you are at work? Is resting the major “activity” or is there some occasional wandering? Is there silence or periodic barking, such as when the mailman comes or a squirrel is seen through a window? The author of this lesson has a couple of schnauzers, known for their predisposition for barking. “Welcome to the Bark Side” is a frequent phrase voiced to passersby while I am taking the schnauzers for a walk. But how much do they bark when cooped up in the house and I am out someplace? And do they move around a lot or mostly nap
