- Why does the tanker crush? Step 1. Observe the giff of the tanker. Step 2. Identify the variables that may be involved and record on CER form in OneNote. Step 3. Make a Claim and add it to form in OneNote. Step 4: Support your claim with evidence (mathematical, diagrammatic, graphically, and texual (observations)). Step 5. Construct an argument on the phenomenon from the giff. (NOTI ou may copy the gill right into your notebook.) Tanker crush from GiffereSolve correctly please. Will rate for correct ansAnswers to all activities will be written on the answer sheet provided. Activity 1 You will need water color or paint (color white and red/black), small container and plastic spoon. Materials may also be based on what is avail able in you place. Pour a small amount of white colored paint in the small container. Slowly add the colored paint then mix. Observe what happens. Repeat if necessary. Questions: 1. What is the resulting color? 2. Does the color produced differ from the original color? Why? 3. Do you think the color white and red/black disappe ar totally?
- 5. You will be given some samples to weigh on the electronic balance in the laboratory. Place a piece of weighing paper on the pan of the balance and push the zero (tare) button so the balance registers 0.000 g. Carefully place one of the samples on the paper and record its mass in table below. Carefully remove the sample. Repeat this procedure for the other samples. Determine the average mass and average deviation of the samples. Show all work. Record the individual masses of each item in the blanks to the left below.
