Force and Motion

Inspired by Leonardo Da Vinci’s self propelled cart design in 1478, students construct cars powered by rubber bands and measure their performance. They will test their cars, make alterations and predictions. Students will gain lively insights into the mechanics, measurement and math of motion. Force and Motion, experimentation, and design all come together to make new discoveries. Great for a followup program on creative elaboration. Exploration and problem solving become obvious when a student has to question why someone's car went further or faster.

All creatures live in a web of resources that support or suppress their growth. Learn about ecosystems and create a dynamic model of an insect’s or bird’s world. Suspend a magnetized creature on a pendulum. Add food and shelter (with magnets) that attract the creature and predators and hazards that repel it. The creature navigates a complex and fascinating path.

Build a windmill with adjustable vanes. You will discover that in order to make it work, the vanes have to be adjusted just right to turn fast enough to work. Then apply that wind power to make it work. How? By making it lift weight, you can observe just how much power output it can produce. You will discover the problem of scale and its limitations but the potential is there.

Understand the gearing needed to manage the lift. About the relationship between speed and power. It's not necessarily intuitive.

Immigrants brought to America traditions of crafting simple playthings out of common materials. These toys develop dexterity and inventiveness. Two toys from the catalog of clothespin classics. Connect to Colonial curriculum or the geography of play.

The English Scientist, Neil Downie, has written three volumes of Saturday Science Projects. His designs are remarkably original and thoughtful, explaining the math and science of every project. Sometimes you have to strip away all the non-essential parts to see an idea at work. Neil Downie proposes a clever study of the exchange of speed for force. A second array of pulleys float between input pulleys and the output pulley. An elegant display of force in motion. Counting on friends: what can your little acrobats tell you about the changes in speed or power (torque)? nspired by: Neil A.

Study motion by building a spiral track for a marble to follow. Understand gravity, friction, inertia. Do you build from the bottom up or the top down? Make discoveries while creating a fun game. 
 

With your own set of acrobats, design, color, and have fun with a theme of your choice. You can also design both sides with opposing themes. Then stack, balance, and construct with these figures. Challenge a friend, build a domino inspired track, see how high and how many you can balance at once. This is a fun challenge and can be fun for all ages.
