Stations Review Notes Please add additional information to your stations worksheets and notes in a different color pen.

Measurement Station Activity 1: Why are units important? Activity 2: Why do units need to be standardized?

Activity 3: Units of Mass, Length, Volume, Time & Temperature A dime is 1.132 mm thick. A metal sphere is measured to be 2.5 ML. A soccer ball is about 0.4005 kg. One mole of CO2 occupies 22.40 L. Professor Dumbledore ran 13.010 miles when he wanted to find Harry. Ginny Weasley would love to have 3125.0 mL of Cherry Coke. Mars measures 450 K.

Activity 4: Making Measurements

Significant Figures and DOUBT • Always go one digit past where the measuring tool is incremented for. This is known as reasonable doubt. For example:

A. 48.1 mL B. 44.9 mL C. 38.0 mL D. 27.2 mL E. 17.9 mL F. 7.1 mL

Activity 5 36.6 mL 41.45 °C

Notebook, Data Tables, & Graphs Station A good data table needs…. A good graph needs… Goods (Million tons) Time (years)

Data Tables Descriptive Title Date USE A RULER Independent variable in first column

A Graph TALKS to you Title Axis Labels Key Scale (even increments)

Accuracy & Precision Station The closeness of a measurement to the actual value of the quantity being measured (How Close) The ability of a measurement to be consistently reproduced under the same conditions (How Repeatable)

THE GOAL OF SCIENCE IS TO BE BOTH.
