Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.
Conjunto de Cráneo de Homínido. El Centro de Extensión y Educación en Ciencias Naturales colabora con la facultad de CSU, los Parques Nacionales y los programas de ciencia ciudadana para traducir su investigación científica actual en experiencias STEM únicas para los estudiantes en forma de kits educativos que se pueden prestar. Cada kit contiene casi todos los materiales necesarios (menos cosas comunes como agua y toallas de papel) para explorar algunos temas de investigación científica realmente interesantes. enviando un formulario de recogida local o un formulario de entrega disponible en el sitio web vinculado. Utilice la información de contacto en la página de descripción general del kit STEM para obtener más información. https://www.cns-eoc.colostate.edu/stem-kits/ Este kit se proporciona de forma gratuita para uso educativo.
This article from the free online magazine Beyond Weather and the Water Cycle provides appropriate science lessons for Grades K-5. The focus is on acquainting young learners with climate-change concepts that are not too complex for their grade level and will not frighten them. In each issue, the magazine develops articles around one of the seven essential principles of climate science. The author believes early lessons about water availability and extreme weather events will prepare students for complex climate concepts they will encounter in later grades.
Numerical models are widely used to simulate systems ranging from climate to traffic jams, yet a high percentage of college-level students have little awareness of how they are constructed and their limitations. This activity is intended to introduce students to the construction and use of a simple conservation equation model using MATLAB. Students will construct, with the help of the instructor, a MATLAB script to simulate inputs and outputs to and from a water tank and the tracking of water volume through time. The activity includes calibration and verification of their model using data on flows observed in the water tank.

Students explore angular momentum using a rotating chair and their own bodies.
Students analyze video clips of kids rolling down a hill on skates, scooters, and bikes to determine whether mechanical energy is conserved.
A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Students use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.
This active demonstration investigates the law of conservation of momentum using a person on rollerblades and a thrown medicine ball.
This simulation shows the difference between Constant Velocity vs. Constant Acceleration هذه المحاكاة تبين الفرق بين السرعه الثابته والتسارع المستمر في الفيزياء
The simulation shows five different motions in which objects experience constant acceleration, starting from rest. Although each motion is different, the underlying physics is the same. What features of the simulation reinforce the idea that the physics is the same?
Successful completion of this cooperative learning activity requires the active involvement of the individual, the small group and the entire classroom (collaboration). The goal is to make a simple task as complicated as possible by constructing a single complex machine.
Context-rich problem for electrostatics in an introductory physics class. The instructional setting uses cooperative group problem solving.
Bluetooth is everywhere—from smartphones to computers to cars. Even though students are exposed to this technology, many are not aware of how they can use it themselves to wirelessly control their own creative projects! For this challenge, students build on what they learned during a previous Arduino maker challenge, Make and Control a Servo Arm with Your Computer, and learn how to control a servo with an Android phone (iPhones do not work with the components used in this challenge). By the end of the exercise, expect students to be wirelessly controlling a servo with a simple phone application!
In this activity, students use a variety of materials to design and create headphones that absorb sound.
This activity describes the construction and use of a pneumatic cannon and free falling target used to teach the concepts of projectile motion in introductory physics.
In this activity, learners make their own heat waves in an aquarium. Warmer water rising through cooler water creates turbulence effects that bend light, allowing you to project swirling shadows onto a screen. Use this demonstration to show convection currents in water as well as light refraction in a simple, visually appealing way.
Students teams design and build shoe prototypes that convert between high heels and athletic shoes. They apply their knowledge about the mechanics of walking and running as well as shoe design (as learned in the associated lesson) to design a multifunctional shoe that is both fashionable and functional.
In this Cyberchase video segment, Matt uses subtraction to help Digit figure out how much time he has left in a cooking contest with Hacker.
Students learn about using renewable energy from the Sun for heating and cooking as they build and compare the performance of four solar cooker designs. They explore the concepts of insulation, reflection, absorption, conduction and convection.
In this video, Jonathan examines the biology of coral reefs and their importance to the marine ecosystem. Please see the accompanying lesson plan that discusses pH and ocean acidification for educational objectives, discussion points and classroom activities.
