Lesson 1.4: Graphs in science

(Unlock) Essential Question:­How are line graphs created?

Learning Target:­Describe and create line graphs.

Vocabulary: ­trend; linear; anamolous data point; CONSTANT SCALEWarm Up: Complete Socrative Assessment. Copy errors and confusions.

Teaching: Review LT; Vocabulary; Socrative Results Task: 1. Read over the information about a young girl named Sarah in the paragraph below:

At age 1, Sarah was 75 cm tall. By the time she turned 2,Sarah had grown by 10 cm. By age 3, she had grown another 10 cm. When she turned 4, Sarah was exactly 100 cm tall.

a. Use pencil to make a data table to organize the information.

b. Use pencil to create a graph that shows Sarah's change in height.

c. Use "Line Graph Checklist" to assess your graph

2. Enrichment: "Graphs in Science"

Summarize: Check your answers using the checklist
