Things you need to have set up ahead of time... 1. Each student needs a straw of their own for stations I and 3. Station 1: Index cards, folded width-wise in the middle, so that they stand up like little tents on the lab table. Station 2: I or 2 liter soda bottle. I piece of scrap paper Station 3: 2 plastic cups Station 4: pre-cut aluminum foil squares, all the same size. I usually make them about 4 or 5 inches on each side. A tub of water. Station 5: pile of pennies. I cup or beaker of water, I cup or beaker of shampoo or other thick liquid you can easily clean up later. I use shampoo in a plastic cup so I can dump most of it back into the bottle and toss the cup instead of washing it.Station 5: Viscosity In front of you are two small beakers, each with different fluids in them. Drop a penny into each beaker at the same time. 1 . What happens? Viscosity is a fluid's resistance to flow. 2. Which fluid do you think has the higher viscosity? 3. Rank the following fluids from least viscous to most viscous: corn syrup, water, shampoo. a . 4. What is another word for 'viscous?'A T A V Station 3: Cup Collapse Set up two plastic cups upside down about one inch from each other (at the bottom). Using a stream of air from your straw, blow between the cups at their base. You may not blow air directly at the cups 1. What happens? 2. If a brisk wind blows between two sky-scrapers, would the windows blow into or out of the buildings? 3. Whose theorem are we demonstrating with these examples? Station 4: Archimedes at Work You have two equal squares of aluminum foil. Fold the first in half, then again and again until you cannot fold it anymore. Place it in the water 1. What happens? Take the second square (that is the same size and therefore the same mass as the first piece) and make a small boat. You want it to float. 2. Can you get it to float? 3. If the pieces of aluminum foil were the same size (and mass), why did one float and one sink? Station 5 Viscosity In front of you are two small beakers, each with different fluids in them Drop a penny into each beaker at the same timelearning.uhv.edu/bbcswebdav/pid-9837309-dt-content-rid-86051340_1/courses/V_20223_SCIE_3320_25653_MAI... - + A Name Properties of Fluids: Minilabs Station I: Tornado! Bernoulli's Theorem states that an increase in fluid speed creates a decrease in pressure. Using your straw, and without touching the index card, flip it over. You must use Bernoulli's theorem to solve this problem. Draw what you need to do to flip the index card Station 2: A Hole in One Make a small ball of paper (like a spit ball, without the spit ) Place it just inside the opening of the bottle. Holding the bottle horizontal, and without using your straw, lightly try to blow the ball into the container. 1. What happens? Why? 2. Use Bernoulli's theorem to explain why this occurs.
