Method and Materials

This is the next stage for my science project, method and materials.

This is what I will need and how I am going to do it...

Materials:

• Water tank; a 38 Litre under the bed type
• Source of water
• Wood, 2 inches (in.) thick x 4 in. wide x 8 in. long
• Permanent marker
• Ruler, metric
• Digital stopwatch
• Lamp; preferably a bright ceiling light directly under which you can position the water tank
• Hand towel
• Volunteer (1)
• Lab notebook
• Graph paper

Procedure:

1. Find an indoor space to work in preferably something that is alright for water to splash on it
2. Fill the tank of water with a few centimeters,have a few practise making and tracking the waves
3. Draw a small line with the permanent marker,around 2.5 cm below the rim of the tank.Draw another line shorter on the end of the rectangular shape.This is the height of where you drop the wood block,Use a volunteer to help you track the waves
4. Once you feel comfortable tracking the waves start the experiment
5. Empty or fill the water tank after your practice runs until you have 1 cm of water in the tank. Use the metric ruler for accuracy.
6. Have your volunteer ready with the stopwatch to start timing how long it takes a wave to travel from one end of the tank to the other. Hold the bottom of the wood block at the mark on the tank. As soon as you drop the block and a wave is created, the volunteer should start the stopwatch. The volunteer should stop the stopwatch when the wave hits the other end of the tank. Record the time in the data table in your lab notebook.
7. Repeat step 6 nine more times to ensure more-accurate data.
1. Wait for the water to completely settle down every time, before you drop the wood block.
2. Hold the wood block the same way each time your drop it into the water tank.
3. Record all data in the data table in your lab notebook.
8. Now fill the water tank until the water depth is 2 cm. Use the ruler to confirm the water depth. Repeat steps 6-7. Record all of the data in the data table in your lab notebook.
9. Fill the water tank until the water depth is 3 cm. Use the ruler to confirm the water depth. Repeat steps 6-7. Record all of the data in the data table in your lab notebook.
10. Empty the tank and repeat steps 5–9 two more times so that you have a total of 3 trials for each depth. Performing 3 trials for each depth ensures that your data is reproducible and repeatable. Be sure to record all of the data in the data table in your lab notebook.

Have you ever read and done a method right?
