Topic: Density
Grade: Elementary (Club/Afterschool)
Duration: 45-50 Minutes
Learning Objectives
Students will define density as the amount of matter in a given volume.
Students will follow a multi-step procedure to create a three-layer density column.
Students will predict and test the density of solid objects relative to different liquids.
Materials Checklist
Per Student/Group:
Clear plastic cup (9-12oz)
Corn syrup (approx 2oz)
Vegetable oil (approx 2oz)
Water (approx 2oz)
Small testing objects (bead, raisin, clip)
Classroom Supplies:
Blue/Green food coloring
Paper towels (for spills)
Spoons or stir sticks
"Density Detective" Worksheets
Lesson Timeline
1. Warm-up & Inspiration
5 Minutes
"Today, you aren't just scientists—you are Science Artists! We are going to create a vertical masterpiece using only liquids and physics."
Show the Lighthouse Lab video. Use these specific timestamps for engagement:
0:57 (The Hook): Pause. Ask: "Think of a crowded elevator vs. an empty one. Which one is 'packed' more? That's density!"
1:12 (Predictions): Pause. Ask: "Before she pours, which of these (honey, soap, oil, alcohol) feels the 'heaviest' for its size?"
2. Activity Setup
10 Minutes
Distribute clear cups. Teacher Tip: Dye the water Blue or Green beforehand so students can clearly distinguish it from the clear oil and golden syrup.
3. Hands-on Experiment
25 Minutes
Layer 1
Corn Syrup (Bottom)
Layer 2
Colored Water
Layer 3
Vegetable Oil (Top)
Instruct students to pour slowly down the side of the cup to avoid mixing. Once layers settle, have them drop their testing objects (bead, raisin, clip) and record where they land.
4. Reflection: The Magic Trick
5 Minutes
Challenge students to explain their project to a parent as if it were a "Magic Trick." What is the secret? (Density! Most dense on bottom, least dense on top).
Common Misconception: "Heavy things always sink"
Students often think weight determines sinking. Remind them that a giant piece of wood (heavy) floats on water, while a tiny grain of sand (light) sinks. It's about how much matter is packed into that volume!

What is Density?
The amount of matter (stuff) packed into a given volume (space).
High Density
Like a crowded elevator! Lots of "stuff" packed tight.
Low Density
Like an empty elevator! More space for the "stuff".

Creating the Masterpiece
1
The Foundation
Slowly pour the Corn Syrup into the bottom of your cup.
2
The Middle Ground
Tilt your cup slightly. Pour the Blue Water slowly down the side.
3
The Sky
Carefully add the Vegetable Oil on top.
Where will it land?
Choose a small object. Predict which layer it will stop in before you drop it!

1. The Artist's Prediction
Before we pour, which liquid do you think is the most dense (will sink to the bottom)? Circle your guess:
CORN SYRUP
WATER
VEGETABLE OIL
2. Draw Your Masterpiece
Color in your layers exactly as they look in your cup. Label which liquid is in each layer.

4. The "Magic" Secret
If you showed this to your parents, how would you explain why the layers don't mix?
