In this experiment, you will measure the volume of a straw by two different methods. You are provided with: • two identical round straws • two set squares • a 30 cm ruler • a 50 cm³ measuring cylinder • scissors • paper towels to mop up any spillage. A container of water is available for you to use. (a) Method 1 (b) Method 2 Take the second straw. Immerse the straw fully in the container of water as shown in Fig. 1.2. [Figure 1.2] Move the straw backwards and forwards in the water several times so that the water enters the straw. Put a finger firmly over one end of the straw and remove the straw from the water. Put the straw above the open end of the measuring cylinder and remove the finger so that the water is transferred into the measuring cylinder. Repeat this process 5 more times for a total of 6 transfers.
