 * __[[image:Group3.JPG width="651" height="457"]]

We are conducting an experiment that is going to show the best time to soak stained clothing to ensure the best results possible.
 * __Introduction: __**

Many people say that putting clothes straight in the wash prevents staining. Our experiment is going to find an accurate answer for sure!
 * __Myth: __**

Our myth is based on the sentence, “put that shirt in the wash before it stains!” often heard shouted by a mother or grumpy granny.
 * __Observation: __**

media type="youtube" key="1TzT9G3NMw0" height="344" width="425"media type="youtube" key="dWxm_O1jyi0" height="344" width="425" Does putting stained white shirts in a bucket to soak straight after they are stained really work?
 * __Background Knowledge: __**
 * __Question: __**

<span style="font-size: 12pt; color: black; font-family: 'Arial', 'sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-weight: bold;">We are staining four shirts at the same time with a cap of tomato sauce. We will put the first shirt in our bucket as soon as the stain is on the shirt for half an hour to soak. We are putting the second shirt in our bucket of water to soak Half an hour after the stain is on the shirt. We are putting the third shirt in the bucket a whole hour after the stain is on the shirt. The fourth shirt is going in the bucket 24 hours after the stain is on the shirt. We will wash the shirts the same way using the instruction found on the back of the Dynamo Liquid container (for soaking). <span style="font-size: 12pt; color: black; font-family: 'Arial', 'sans-serif'; mso-fareast-font-family: 'Times New Roman';"> <span style="font-size: 12pt; color: black; font-family: 'Arial', 'sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-weight: bold;">We think the first shirt (the one that is going in the bucket immediately) will be the one that has the least of a stain after the soaking.

Make a mark where the stain falls on the section of the colour wheel. 4. Do the same with the other 3 shirts. <span style="font-size: 12pt; background: black; color: aqua; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-weight: bold;">The mark that is closest to the white in the middle of the colour wheel is the one that shows the best time to soak a stained shirt. <span style="font-size: 12pt; color: black; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-weight: bold;">

<span style="font-size: 12pt; color: black; font-family: 'Arial','sans-serif'; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-weight: bold;">The first shirt was the one that had the least of its stain left proving our hypothesis correct. The second shirt had the second best score. The third had the second worst score and the fourth shirt had the worst score out of the four.

We can finally conclude, after days of working, that putting clothes straight in the wash really does prevent staining.
