Interactive, visual math puzzles that must be figured out to make the mobile balance. Starts with simple puzzles and builders. There is also an option to build your own puzzle.
• Guess My Number
By: CS Unplugged
This is similar to the game of 20 questions, but it is about guessing a number with the strict rule that you can only answer whether the secret number is greater than or equal to a guessed number.  Demonstrates how dividing larger problems in half, and then half again makes larger problems into smaller easily solvable problems very quickly.
• How Computers Work
By: Code.org
Age Group: All Ages
Six short (3-5 minutes) videos designed to be approachable for everyone and easy to understand. The series explains what makes a computer a computer, how digital information is represented in 1s and 0s, how computer circuits work to manipulate digital information, and how a central processing unit (CPU) and operating system control the inputs, outputs, memory, and hardware of a computer.
• Create Your Own Flappy Game
By: Code.org
Age Group: Ages 4-104
Use drag-and-drop programming to make your own Flappy Bird game, and customize it to look different (Flappy Shark, Flappy Santa, whatever). Add the game to your phone in one click.
• Minecraft
By: Code.org
Age Group: Grades 2 and up
Use blocks of code to take Steve or Alex on an adventure through various Minecraft worlds.  Select from underwater worlds, hero’s journey, adventurer, or designer options.
• Intro to App Lab
By: Code.org
Age Group: Ages 13+
App Lab is a programming environment where you can make simple apps. Design an app, code in JavaScript with either blocks or text, then share your app in seconds.
• Scratch
By: Code.org
Age Group: Ages 8-16
Scratch is a programming language and an online community where children can program and share interactive media such as stories, games, and animation with people from all over the world. As children create with Scratch, they learn to think creatively, work collaboratively, and reason systematically. Scratch is designed and maintained by the Lifelong Kindergarten group at the MIT Media Lab.
• How AI Works
By: Code.org
Series of short videos (3-5 minutes) will introduce you to how artificial intelligence works and why it matters. Learn about neural networks, or how AI learns, and delve into issues like algorithmic bias and the ethics of AI decision-making.  Final Panel Discussion Webinar Video (49 minutes) on the Ethics of AI sponsored by Microsoft and Code.org.
• Fermenting Yeast and Sugar
By: SciGuys
Welcome to science at home in this experiment we are exploring the fermentation between yeast and sugar. Yeast uses sugar as energy and releases carbon dioxide and ethanol as waste. Yeast and fermentation have been used for thousands of years when making bread. At the end of this episode you will be able to demonstrate fermentation, explain why yeast and fermentation make a balloon grow and explain the chemical reaction that occurs during fermentation.
• Science Snacks
By: Exploratorium
Age Group: All ages
Science Snacks are hands-on, teacher-tested activities that bring explorations of natural phenomena into the classroom and home. Each activity uses inexpensive, easily available materials, offers detailed instructions and images, provides a clear explanation of what's going on, and is adaptable to a wide range of curricula, content areas, grade levels, and settings.
• Bubbling Plants Experiment to Quantify Photosynthesis
By: TeachEngineering
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. Additional activities can be found at www.teachengineering.org.
• Bouncy Egg Science Experiment
This experiment shows how to convert a raw egg into a bouncy egg using materials in your kitchen. An explanation of the process and instructions for additional experiments are found at www.coolscienceexperimentshq.com.
• Making Kombucha Leather
By: Grow It Yourself Biobuddies
A tutorial that shows how to use the SCOBY (symbiotic culture of bacteria and yeast) that forms when the fermented beverage kombucha is made. The SCOBY can be dried, and dyed to make a product sometimes called “vegan leather”.
• Gummy Bear Osmosis
