(1)
Problem1:Adhesive tape

Problem1:Adhesive tape

Determine the force necessary to remove a piece of adhesive tape from a horizontal surface. Investigate the influence of relevant parameters




(2)
Problem2:Air drying

Problem2:Air drying

Table utensils (dishes, cutlery, etc.), after being washed, dry differently. Investigate how the time of drying depends on relevant parameters.




(3)
Problem3:Bouncing flame

PlacProblem3:Bouncing flame

Place a flame (e.g. from a Bunsen burner) between two charged parallel metal plates. Investigate the motion of the flame.




(4)
Problem4:Breaking spaghetti

Problem4:Breaking spaghetti

Find the conditions under which dry spaghetti falling on a hard floor does not break.




(5)
Problem5:Car

Problem5:Car

Build a model car powered by an engine using an elastic air-filled toy-balloon as the energy source.Determine how the distance travelled by the car depends on relevant parameters and maximize the efficiency of the car.




(6)
Problem6:Convection

Problem6:Convection

In a container filled with a liquid, heat transport will occur when the bottom of the container is heated and the top surface is cooled. How does the phenomenon change when the container rotates about its vertical axis?




(7)
Problem7:Cup drum

Problem7:Cup drum

A plastic cup is held upside-down and tapped on its base. Investigate the sound produced when the open end of the cup is above, on or below a water surface.




(8)
Problem8:Domino amplifier

Problem8:Domino amplifier

A row of dominoes falling in sequence after the first is displaced is a well known phenomenon. If a row of "dominoes" gradually increases in height, investigate how the energy transfer takes place and determine any limitations to the size of the dominoes.




(9)
Problem9:Escaping powder

Problem9:Escaping powder

When a hot wire is plunged into a beaker of water with powder (e.g. lycopodium) floating on the surface, the powder moves rapidly. Investigate the parameters that alter the speed of movement of the powder.




(10)
Problem10:Faraday heaping

Problem10:Faraday heaping

When a container filled with small spheres (e.g. mustard seeds) is vibrated vertically with a frequency between 1 – 10 Hz, so called Faraday heaping occurs. Explore this phenomenon.
