how to write procedure
Procedure:
1. Cut a white cotton t-shirt into 4 strips that are 10 by 3cm, and cut a coffee filter into quarters.
2. Draw a 5cm line on each of the pieces that you just cut out.
3. Pour 250mL of water into a bowl that is wide enough to fit your strips of fabric.
4. Place one strip of fabric into the bowl of water. Set a timer for 20 minutes.
5. After the 20 minutes is up start a stopwatch and scrub the fabric for up to 5 minutes.
6. When the marker has dissolved out of the fabric stop the time.
7. Record the time in a chart.
8. Repeat steps 3-7 with vinegar, Tide and Dish soap.
Materials:
No Name lemon fresh dishwashing liquid
Co-op pure white vinegar
Original Tide
Water
Safeway disposable coffee filter
Sharpie permanent marker
4 medium size Bowls (large enough to fit the fabric and coffee filters.)
Stopwatch/timer
Scissors
Ruler
Hypothesis:
Our hypothesis is that the Tide will take the Sharpie out of the cotton the fastest. We think this because we know that laundry detergent is made to take stains out of fabric. we assume that the dish soap will take it out of the coffee filters the fastest because dish soap can take sharpie out of your skin.
Errors:
The coffee filters easily ripped. The sharpie permanent marker could be old. The measurements on the ruler could be inaccurate. Future improvements:
We could have put the line of permanent marker on the cotton and coffee filter right before we put it in the liquid. We drew the line of marker on all the material at the same time we shouldn’t have done this because it may set in the fabric.
Conclusion:
Our conclusion is that the vinegar dissolved the permanent marker out of the coffee filter the best and the quickest. The majority of it dissolved within twenty minutes. Tide dissolved the sharpie out of the cotton fabric the best and the quickest within twenty three minutes and forty five
