NGSS 1-PS4-3
Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.
At a Glance
THIS STANDARD FOCUSES ON
Discovering that different materials interact with light in different ways — some block it, some bend it, some split it into its spectrum of colors. The Rainbow Paper experiment demonstrates thin-film interference: a nail polish layer on water splits white light into all visible colors.
KEY SKILLS ADDRESSED
Observation of color and light, prediction, recording visual results, drawing as scientific documentation, making real-world connections
CORE CONCEPTS
Refraction, light spectrum, thin-film interference, wavelength, reflection, transparent vs opaque vs translucent
HOW BRAINIAC BUNCHSUPPORTS THIS
Episode 1's Rainbow Paper Magic is the most visually dramatic experiment in Season 1 — kids dip black paper in nail-polish-water and watch a full rainbow appear on the paper. White light's hidden colors, revealed.

Standard Code:
NGSS 1-PS4-3
Grade Level:
Grade 1
Performance Expectation:
Plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.
Disciplinary Core Idea:
PS4.B: Electromagnetic Radiation — Objects can be seen if light is available to illuminate them or if they give off their own light. Some materials allow light through them, others do not.
How Our Content Aligns
Mapping Brainiac Bunch resources to this standard
Little Lab Challenges supports NGSS 1-PS4-3 through Episode 1: Rainbow Paper Magic, where kids observe that a thin nail polish film changes how light behaves — splitting white light into the visible spectrum. This meets the standard's requirement to investigate how materials in the path of light produce different effects.

Little Lab Challenges • 8 minutes • Ages 5–10
Using This Standard Across Ages
For Younger Learners (Ages 5-6)
Focus entirely on the drawing area of the Color Observation Log — have kids choose colored pencils to match what they saw and fill in the circle. Ask verbally: 'How many colors can you count?' Count together. Skip the written question boxes; use the color dot row to circle observed colors instead.
For Grade-Level Learners (Ages 7-8)
Complete all three question boxes in the Color Observation Log. After the experiment, ask: 'Freddy said the nail polish splits light — what does split mean?' Check that kids can describe at least 3 colors and connect the nail polish film to the color appearance. Introduce the vocabulary strip words as three new science terms for the week.
For Advanced Learners (Ages 9-10)
Test multiple nail polish colors — does the color of the nail polish change the rainbow? (No — the film thickness matters, not the pigment color.) Look for rainbow colors on soap bubbles, oil puddles, and CDs — same science! Ask: 'Why does a bubble show more colors near the edges than in the center?' Connect to the concept that thinner films produce different colors than thicker films. This is a direct link to wave optics studied in middle school.
Evidence of Learning
Observable outcomes and assessment support
Students demonstrate mastery when they can:
✓ Predict at least 2 colors that will appear before the experiment.
✓ Record the colors they observed, naming at least 3 correctly.
✓ Explain in their own words that the nail polish changed how the light behaved.
✓ Connect the experiment to one real-world example of the same phenomenon (soap bubbles, oil puddle, or CD surface).
Assessment Note:
Color Observation Log (observation recording formative), oral exit: 'Show me the colors that appeared — which surprised you most?', portfolio: display the Color Observation Log alongside a sentence explaining why the colors appeared.
