Classic Folk and Fairy Tales Paired With Engaging STEM Challenges:
These STEM activities relate to the characters and plots by turning the story’s challenges or problems into hands-on investigations for students to solve. For example, students might design a sturdy house for the Three Little Pigs, build a tower or elevator for Rapunzel, or create a way for the Gingerbread Man to cross the river.
This approach encourages problem-solving, creativity, and engineering thinking, as learners use the context of familiar stories to brainstorm, design, test, and improve their solutions.

Progressive Complexity
If you’re learning about a particular science concept, you can start with a beginner’s experiment, then build upon the same concept by progressing to a more challenging activity. At the Science Buddies site, you can find experiments of increasing complexity using their difficulty scale. Let’s say you want to do some experiments with bubbles. Start out with a beginner’s project to make your own bubble solution. Learn about what makes good bubble solution and learn science concepts like surface tension and physical and elastic properties. Then, use the solution you made to progress to a second experiment to determine which materials can catch bubbles without popping them.
Another example involves experimenting with seeds. Do an investigation to determine the number of seeds produced by different fruit. Then do a harder project to investigate how the size and shape of fruits or seeds affect their dispersal by the wind.
These activities start simple and gradually become more challenging, helping kids build confidence and skills as they go. Early experiments, like blowing up a balloon without using your mouth, introduce basic scientific concepts with easy-to-find materials. Later activities, such as testing what’s inside coins or exploring whether a magnet can be “turned off”, delve into more advanced ideas in chemistry and physics.
With projects covering biology, engineering, and even outer space, this book encourages kids to explore, experiment, and discover the science behind everyday questions at their own pace.

Cross-Disciplinary Connections
You can stick to studying concepts within a particular branch of science. For example, do a series of experiments involving chemical reactions by making a volcano, or making different slimes. Or you can investigate energy and motion by building a balloon-powered car or paper helicopter.
Another option is to do experiments that combine different branches of science to get a more holistic view of scientific principles. For example, make a lemon battery and learn about chemical reactions, the flow of electrons through a circuit, and design aspects of engineering. Or put physics and engineering to use when you make a hovercraft and learn about air pressure and friction.
Over 100 hands-on experiments, each with clear explanations of the science behind them. Activities span physics, chemistry, biology, engineering, and art, helping kids explore everything from chemical reactions (like making a fizzy rocket) to engineering (building a magnet-powered car) and earth science (creating a pencil sundial). Each experiment highlights which scientific concepts are involved, making it easy to connect the activity to broader learning.

Historical Time Travel
Take a journey through time and do experiments that correspond to a particular time period.
Make a sundial and learn about how ancient civilizations used them and other implements to measure time and seasons.
Make papyrus and learn about the paper-making process of yesterday and today.
Another way to link history and science is to read biographies of famous scientists and do simple experiment recreations. For example, you can do a version of Galileo’s falling objects experiment.
