How does the angle of a solar panel relative to the sun affect its power output? How does this affect the speed of a model solar-powered car? You should take this into account when building your own solar-powered car for a competition like the Junior Solar Sprint. See the Science Buddies website for an NGSS-aligned classroom lesson plan: https://www.sciencebuddies.org/teacher-resources/lesson-plans/solar-powered-cars-junior-solar-sprints?ytid=SyQQt0jzLu4&ytsrc=description and instructions for…
The Planetary Society's citizen-funded mission, LightSail-1, will launch on a SpaceX Falcon Heavy in 2016. It will test solar sails to propel low-cost "cube-sats," with technology that could open highways to the planets. STORY: http://goo.gl/7t
Test the limits of solubility! In this fun science activity, you will find out how much of a compound is too much to dissolve in water. https://www.sciencebuddies.org/stem-activities/solubility-limits?ytid=6nEH2XlcJt8&ytsrc=description
Science Buddies also hosts a library of instructions for over 1,000 other hands-on science projects, lesson plans, and fun activities for K-12 parents, students, and teachers! Visit us at https://www.sciencebuddies.org/?ytid=6nEH2XlcJt8&ytsrc=description to…
You probably know that light travels in straight lines. So, how can you guide a light beam through a maze and around obstacles to a target? You can use mirrors to do that! As light bounces off of reflective surfaces, you can redirect a light beam to wherever you need to if you place the mirrors correctly. Can you solve the mirror maze challenge shown in this video? Written instructions as well as free maze and target templates are available on our website at…
This video shows you how to create a K-Means model to categorize songs into a set number of categories using machine learning and libraries on Google Colab. Written instructions and example code are available on the Science Buddies website: https://www.sciencebuddies.org/science-fair-projects/project-ideas/ArtificialIntelligence_p012/artificial-intelligence/K-Means-Spotify?ytid=PnLz0L7LGhE&ytsrc=description
K-Means overview video: coming soon!

Sound waves in a tube of gas create flames of different heights that dance to the music. A metal tube with holes in it is filled with gas. The gas is lit to create a row of tiny flames. A speaker at one end plays sound into the tube, which creates a standing wave of sound: areas where air molecules are vibrating rapidly separated by areas where the air is fairly still. This produces the different heights of flames and allows the wavelength of the sound wave to be estimated.
This video is a quick overview of our sound-following Arduino robot project. The robot uses two microphones to drive toward a sound source. You can find written instructions, including a parts list, circuit diagram, and example code, on our website: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Robotics_p048/robotics/sound-tracking-robot?ytid=AUguvwpnJ5M&ytsrc=description We also have a separate tutorial video about using a microphone with an Arduino:…
This video provides an introduction to squishy circuits as a classroom activity, for teachers and educators who want to use squishy circuits in an in-school or after school setting. This is the first video in a two-part series. The second video goes into more detail about the basic circuit terminology and concepts that can be taught with squishy circuits. Kit available here: https://www.homesciencetools.com/product/squishy-circuits-kit/?aff=SB1
To view full directions for this activity, see…
This video is an introduction to the Squishy Circuits kit, which lets you use electrically conductive play dough to make simple circuits and add lights to your sculptures. This kit is used in three different Science Buddies project ideas (intended for science fair use).
