Stations-ID: A014

Instruction:

Press your hands on the different boards. Compare the different surfaces. What do you notice? Which boards are warmer, which are cooler? Is it a sunny day?

Stations-ID: D002

Instructions:

A normal pendulum swings back and forth steadily and predictably. But what happens when you attatch a second pendulum to it?

• What do you think, will both double pendulums move in the same way?

• Hold the longer pendulum and set the short one in motion.

Now let the longer pendulum go. What happens?

Based on his calculations in the field of astronomy, the French physician and mathematician Jules Henri Poincaré (1854-1912) posed the question if all physical phenomena are predictable. In his bestseller “Science and Method” (1912) he gave the following answer: „It is possible, that small differences in the initial circumstances lead to big differences in the results (…) prediction becomes impossible and we are left with a random phenomenon.“

Stations-ID: D007

Instructions:

Start and endpoint are the same for both spheres. One of the spheres rolls along an inclined plane, the other takes a longer way. 

• Which will reach it’s goal first?
• Which sphere arrives at the destination with a higher velocity?
• What would happen, if the spheres where of different sizes?

Marbles are not a new invention. The oldest finds are from Egypt and around 5.000 years old. The first glass marble on the other hand was made in Lauscha, Thuringia, Germany in the 19th century.

Stations-ID: D087

Instructions:

Whose sphere is the slowest?

Find a partner and build the longest possible marble run. You determine the rules yourself, e.g. whether all the slats are to be used, or only a certain number.The inclination of the surfaces can be changed by turning the rear ball feet. Please only turn it as far as is necessary to ensure a secure stand.

Light-machine: Turn the red crank wheel. Now press the three red buttons in turn. What happens? What difference is there between the 3 lamps? Do you also notice a difference when cranking?

Stations-ID: D089

English instructions:

Wooden channels adhere to a metal wall with magnets.
• Who will build the most clever, the fastest or the slowest marble track?

Stations-ID: D097

Instruction:

Pumping heat :
Turn the red crank wheel for a while. Now grasp the two copper coils with one hand each. Do you notice a difference? Where do you think it comes from?

Stations-ID: D086

Instructions:

Start and endpoint are the same for both spheres.

One of the spheres rolls along an inclined plane, the other takes a longer way.

• Which will reach its goal first?
• Which sphere arrives at its destination first, which arrives quicker?
• What would happen, if the spheres were of different sizes?

Playing with marble runs is not just a nice physics’ pastime. Designers of roller coasters or toboggan runs can not do without a solid knowledge of rolling curves and their mathematical description.
