What is matter? Matter-any substance that has mass and takes up space Matter-any substance that has mass and takes up space

How is matter measured in science? Mass-the amount of matter a substance/object has (grams) Mass-the amount of matter a substance/object has (grams) Volume-the amount of space a substance/object takes up (liters) Volume-the amount of space a substance/object takes up (liters) Length-the distance between points (meters) Length-the distance between points (meters)

What are the tools of measurement in science? Mass Mass Volume Volume Length Length Triple-beam balance Graduated cylinder/beaker Meter stick/ruler

Mass-Triple-beam balance

Volume-Graduated Cylinder

Length-Meters

How are graphs used in Science? Visually shows the relationship between two variables Visually shows the relationship between two variables Independent variable (x-axis)-causes a change in the dependent variable Independent variable (x-axis)-causes a change in the dependent variable Dependent variable-measureable outcome (y- axis) Dependent variable-measureable outcome (y- axis) Graphs are used to display and analyze data from experiments and observations Graphs are used to display and analyze data from experiments and observations

Data Analysis in Science Data is collected. Data is collected. The data is displayed in graphs. The data is displayed in graphs. The data is analyzed (ie patterns, trends, and insights). The data is analyzed (ie patterns, trends, and insights). Scientific Thinking-Evaluation of results and hypotheses Scientific Thinking-Evaluation of results and hypotheses

When are the different types of graphs used? Line Graph Line Graph Pie Graph Pie Graph Bar Graph Bar Graph Used to track changes over short/long periods of time. Compare parts of a whole. Used to compare between different groups or track large changes over time.

Summary Questions: How is matter defined? How is matter defined? What are some of the tools scientists use to measure matter? What are some of the tools scientists use to measure matter? How are graphs used in science? How are graphs used in science?
