View Bozeman science video Systems and System Models

What systems can you see in where buildings are located?

• Where are places that people live located?

• Where are places that people work located?

• Where are places that people gather (shopping, sports) located?

• Where are places that store waste/recycling located?

• What does your neighborhood look like?

• Where are buildings, parks, green/wild spaces?

Choose two or three different areas of your yard to investigate over the next two weeks.

• What surfaces are being eroded in your area?

• What are the materials these surfaces are made of?

• What erosion forces might you find? (Rain dripping from a downspout, for example)

You might choose to identify these areas on the topographic map of your area if you made or found one online. (If you want to do that now, just look back at the last lesson set.

Materials

• Tape or other materials that can be used to attach pieces of your raceway together.

• Paper tubes, paper plates, cardboard cartons

• Marbles, small balls, cars, or other items that can toll through your raceway

The Challenge

• Design a structure using your materials that is either free standing or attached to a wall. This structure will be your raceway for marbles, a car, or another object of your choice.

More Ideas

• Try building the longest raceway that you can.

• Try building a raceway with curves and jumps

• Build two or more raceways and hold a competition

• Decorate your raceway.
