For each experiment you will: 1. Predict what you think will happen when you carry out the experiment. 2. Explain your prediction (using the concepts of fluid dynamics that you have learned in this activity such as Bernoulli's Principle). 3. Observe: Carry out the experiment and observe the result. 4. Explain the result (again using fluid dynamics concepts). At each stage, you are to record your thoughts. Part A - Paper Tent Airflow Fold a piece of paper in half lengthwise. Place the paper on a surface, such as a table, so that it forms a tent with openings on each end. Blow through the opening to create fast moving air flowing through the tent.Part B- Tabletop Coin Airflow Place a coin (the lighter the better - a dime is probably best) on the edge of a table. Blow air horizontally over the top of the coin.Part C- Straws and Water Airflow Danger . Make sure that there is nothing in the danger zone that might not mix well with moisture, such as an electrical device or a new hardwood floor. For maximum safety, perform this experiment over a sink. Fill a glass or other container with water; for the best results, fill the glass close to the top. Place a straw vertically in the glass; for the best results, cut this straw so it is as short as possible while still rising above the rim of the glass. Place a straw horizontally so that it is aimed at the top of the vertical straw. Blow through the horizontal straw.Part D - Blower and Ping Pong Ball Airflow O . You will need a device to direct airflow upward - this could be a straw (a bendy straw would work better since you can bend it to direct the flow without straining your neck) but a hairdryer or vacuum cleaner with the hose hooked up to the exhaust port will work best. Direct the airflow upward and place the ping pong ball directly above the outlet
