Learn to create and interpret bar graphs and line graphs through interactive data visualization activities.

50 minutesData VisualizationWeather TrackingReal-World Applications
Learning Scenario: Weekly Temperature Tracking

The Challenge:

You're tracking the temperature each day this week: Monday 75°F, Tuesday 80°F, Wednesday 78°F, Thursday 82°F, Friday 85°F. Create both a bar graph and line graph to show this data.

Weather Tracking Challenge

Graph Solutions:

Bar graph: Show each day's temperature
Line graph: Show temperature changes
Label axes: Days and Temperature
Use different colors for each day

Graph Types Guide

Bar Graphs:

Compare different categories

Show how much of each category

Bars don't touch

Each bar represents one category

Examples

Favorite colors, number of pets, test scores

Line Graphs:

Show changes over time

Connect points with lines

Lines connect points

Shows how data changes

Examples

Temperature over time, plant growth, test scores

Practice Examples

Bar Graph Examples:

Favorite Colors: Red: 8, Blue: 12, Green: 6

Books Read: January: 3, February: 5, March: 4

Test Scores: Math: 85, Reading: 92, Science: 78

Pets: Dogs: 10, Cats: 8, Fish: 5

Line Graph Examples:

Temperature: Mon: 75°, Tue: 80°, Wed: 78°

Plant Growth: Day 1: 2cm, Day 2: 3cm, Day 3: 4cm

Savings: Week 1: $5, Week 2: $10, Week 3: $15

Steps: Mon: 5000, Tue: 6000, Wed: 5500
