Thinking Like a Scientist: ClassifyingBy classifying the information related to a chimp’s resting, climbing, or feeding, a scientist can better understand chimp behavior. Use the chart to classify the details from the field notes.

Measurement—A Common Language

SI PrefixesSI units are similar to our money units, in which a dime is ten times more than a penny. Name the example for each of the SI Prefixes.

Some SI Units of Measure

Measurement—A Common Language

Compare and ContrastName the similarities and differences of mass and weight.

Measurement—A Common Language

Volume of LiquidsMeasuring the volume of liquids and rectangular solids requires different methods.

Measurement—A Common Language

Densities of Some Common SubstancesKnowing the density of an object helps you predict how it will float and identify what it is made of.

Measurement—A Common Language

Temperature ScalesZero on the Kelvin scale (0 K) is the coldest possible temperature. It is called absolute zero. What is the boiling point and what is the freezing point on the Celsius thermometer?

Measurement—A Common Language

Mathematics and Science

Accuracy and PrecisionIn a game of darts, accurate throws land close to the bull’s eye. Precise throws land close to one another. Where would darts land in the situations described on boards C and D?

Mathematics and Science

Significant FiguresSuppose you are tiling a bathroom. You might estimate that the tile is 5.3 cm long. The measurement 5.3 cm has two significant figures, or sig figs. You are certain of the 5, but you have estimated the 3.

Mathematics and Science

The percent error in the calculation of the density of copper was 5.04%.

Percent ErrorThe experimental density of copper is 9.37 g/cm3. The true value is 8.92 g/cm3. To calculate the percent error, use the following formula and substitute.

Mathematics and Science

Hognose Snake Egg DataWe can use math to analyze the data in the table about the number of hognose snake eggs in seven nests.

Think Like a ScientistHow and why are the number of sea turtle nests in Florida changing?

Graphs in Science

A Line GraphThis line graph plots the data from the table.

Graphs in Science

Panda GrowthPanda cubs grow quickly in their first few months of life.

Graphs in Science

Linear TrendsData plotted in a line graph may show a trend. Is the graph linear or nonlinear? What is the graph’s trend?

Graphs in Science

Data VariationEven though some points do not fall on the line, this graph shows a trend. What is the anomalous data point?

Graphs in Science

Distance BikedThis graph shows the distance two friends biked in one hour.

Developing a HypothesisOffer two hypotheses for why the student's digital music player stopped working.

Scientific Inquiry

Scientific Inquiry

Design and Conduct an ExperimentIdentify the independent variable, the dependent variable and the other two variables in this experiment. Think about a hypothesis for this experiment.

Scientific Inquiry

Collecting and Interpreting DataA data table helps you organize the information you collect in an experiment. Graphing the data may reveal any patterns in your data.

Scientific Inquiry

Drawing ConclusionsSometimes the same experiment can have very different data.
