1. Cut at least 28 pieces of 100% cotton fabric into approximately 3 inch squares. 2. Use a permanent marker to label each of the fabric pieces using all of the combinations of stain and detergent mixture. (stains= ketchup, mustard, blueberry syrup, prune juice; detergent mixtures=water, vinegar, vinegar and baking soda, commercial pre-treatment, commercial laundry detergent, vinegar and baking soda paste +laundry detergent, commercial pre-treatment + laundry detergent. 3. Place a stain on each sample according to the labels. W=water (50mL) V=vinegar (50mL) V+bs=vinegar +baking soda solution (30mL vinegar/20mL baking soda) cpst+w=commercial pre-stain treatment +water (20mL commercial pre-stain treatment +30mLwater) ld=laundry detergent +water (20mL laundry detergent+30mL water)vbp+ld=vinegar, baking soda paste + laundry detergent (10mLvinegar+40mL baking soda)+(20mL laundry detergent +30mL water) cpst+ld= commercial pre-stain treatment + laundry detergent 20mL commercial pre-stain treatment +30mLwater) + (20mL laundry detergent+30mL water) 4. Place each sample in the detergent mixture and scrub for 2 minutes. 5. Remove excess liquid and compare the samples when they are dry.

What is bias?

Poll

PIck the two correct types of observations

• qualitative is how many and quantitative is numerical values.

• qualitative is description and quantitative is how many

• quantitative uses instruments for recording

  qualitative uses photographs

Station #1- The Scientific Method (Experiments)

• Hypothesis- An explanation for an observation.

• Variable- Anything that can change in an experiment.

• Independent Variable- A manipulated variable that determines the change in the dependent variable.

• Dependent Variable- the observed variable that is affected by the independent variable.

• Control- the standard that remains constant in the experiment. They remain constant and are not manipulated during the experiment.
