🔍 Part 1: Graph Type Detective

I can identify different types of biological graphs and their purposes.

1. Which graph type is BEST for showing how bacterial population changes over time?

Bar graph

Line graph

Pie chart

Scatter plot

2. A scientist wants to compare the average height of plants grown with different fertilizers. What graph should they use?

Line graph

Bar graph

Histogram

Scatter plot

3. Check ALL graph types that could show a correlation between two variables:

Scatter plot

Line graph

Pie chart

Bar graph

4. What type of graph would best show what percentage of a forest ecosystem is made up of different tree species?

Line graph

Scatter plot

Pie chart

Histogram

📊 Part 2: Data Trend Analysis

I can interpret data trends and analyze correlations in biological graphs.

5. A graph shows enzyme activity (y-axis) vs. temperature (x-axis). The line goes up from 32°F to 98°F, then drops sharply after 98°F. What can you conclude?

6. In a scatter plot showing plant height vs. amount of sunlight, the points form an upward trend from left to right. This shows a _____________ correlation.

positive

negative

no

7. A line graph shows that as predator population increases, prey population decreases. Explain why this biological relationship makes sense:

🎯 Part 3: Graph Matching Challenge

I can match appropriate graph types to specific biological scenarios.

Biological Scenario

A. Comparing average blood pressure in different age groups

B. Showing how heart rate changes during exercise over 30 minutes

C. Displaying the proportion of different blood types in a population

D. Investigating if there's a relationship between study time and test scores

Best Graph Type

1. Scatter plot

2. Bar graph

3. Line graph

4. Pie chart

8. Extension Activity (Honors): Design your own biological experiment and explain what type of graph you would use to display your results. Include your hypothesis and variables.

9. Differentiation Support: Circle the key words that help you choose the right graph type: "changes over TIME" → _______ graph, "COMPARING categories" → _______ graph, "parts of a WHOLE" → _______ chart
