Have you ever wondered why the yummy pieces in your cereal cluster in one area or why your trail mix is never well mixed? Watch this video and find out why this happens! This is our third entry in the @veritasium Science Communication Contest. It was made by Dr. Sabine DeBrabandere, a Science Buddies' staff scientist.

This video shows you how to train a K-Nearest Neighbors (KNN) model to classify breast cancer tumors as malignant or benign 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_p010/artificial-intelligence/KNN-breast-cancer?ytid=w5Ie1u4KW3o&ytsrc=description
A conceptual overview of the KNN algorithm:…
Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size, determine the measures of…
Do you know what kind of birds live in your neighborhood? Have you ever taken a closer look at what they look like and what they do all day long to survive? In this activity, you will build a bird feeder to attract birds, so you can study them. https://www.sciencebuddies.org/stem-activities/build-bird-feeder?ytid=_uruQS6EJyI&ytsrc=description

No one, not even a very strong human, is strong enough to lift a truck. However, our brains are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! This video explains how to build a hydraulic lift yourself!
