🔬 Understanding Chromatography

1. What is chromatography? (Choose the best answer)

A way to mix colors together

A method to separate mixtures

A type of photography

A way to make new chemicals

2. In chromatography, substances separate because they:

Move at different speeds

Change colors

Get bigger

Disappear

3. Which materials do we need for paper chromatography? (Check all that apply)

Filter paper or coffee filter

Water or other liquid

Markers or ink

Microscope

🧪 Hands-On Exploration

4. Prediction: Before starting your chromatography experiment, which marker color do you think will separate into the most different colors? Why?

5. Observation: Draw what you see happening to your marker dot as the water moves up the paper:

6. Results: Complete this sentence about your experiment:

The _____________ marker separated into _____ different colors. The colors I saw were _________________, _________________, and _________________.

7. Compare Models: How is this chromatography model different from the one you used before? List two differences:

Difference 1: _________________________________________________

Difference 2: _________________________________________________

8. Real-World Connections: Scientists use chromatography to solve problems. Circle one way scientists might use this method:

Test if medicine is pure

Make food taste better

Build stronger buildings

Grow taller plants

9. Extension Challenge: If you wanted to separate a mixture of salt and sand, would chromatography work? Explain your thinking:

10. Success Check: Rate how well you understand chromatography (circle one):
