In this Grade 3 science lesson from Science: A Closer Look, students learn how to describe an object's position using relative location words such as over, under, and next to, as well as by measuring distance in standard and metric units. Students also explore the concept of motion, discovering that an object is in motion when its position changes, and identify different types of motion including straight line, zigzag, and back and forth. The lesson connects to real-world examples like snowboarding to help students understand how position and motion are observed and described.
Section 1
Scientists Compare Objects to Describe Position
Position is the location of an object described by comparing it to other objects. Words like over, under, left, and right give clues about position, while distance measures space between objects.
Section 2
Objects Change Position During Motion
Motion occurs when an object's position changes. Objects can move in different ways including straight lines, zigzags, back and forth, or round and round, creating various types of movement patterns.
Section 3
Speed Measures How Quickly Objects Move
Speed describes how far an object travels in a certain amount of time. Fast-moving objects cover more distance than slow-moving ones in the same timeframe, measured in units like kilometers per hour.
Section 4
Technology Helps People Travel Farther
Throughout history, humans created machines like airplanes and spaceships that extend our ability to travel. These technologies solved problems of distance and helped people explore distant places on Earth and beyond.
