The DK Super Simple guides are visually rich overviews designed to make intimidating subjects feel approachable. Each book breaks down core concepts into digestible chunks with colorful diagrams, charts, key-fact boxes, and clean layouts that are perfect for visual learners. These guides shine as supplements that are great for reference, quick review, or introduction before diving deeper into a topic. While they’re not meant to be full curricula, homeschoolers benefit from the clear explanations and bite-size format making science topics feel less overwhelming. Ideal for upper-elementary through high school as a companion resource.
You can find full courses for chemistry, physics, and biology at Khan Academy and CK-12. Not only are the courses free, but they give you a logical structure to follow, while still enabling the flexibility to pick and choose the topics you want to use. The CK-12 flexbooks include lesson planners and quiz creators. There are also chemistry and physics simulations and life science simulations.
Check out these sites with free experiments and activities you can do at home:
Kitchen Chemistry: Play around with fireworks in a glass to demonstrate buoyancy and density; explode some sandwich bags to learn about pressure; use household materials to make a simple thermometer and learn about expansion of liquids. With explanations of the science that’s happening.
Science Buddies Activities: Here, you’ll find instructions for building roller coasters, balloon cars, catapults and telescopes out of everyday materials, while learning about various physics concepts. You can also try out some human biology activities to learn about things like germs and hand-washing; fingerprint patterns; genetics and DNA and more. With videos, science explanations, and resources for further exploration.
