How Light Travels Activity: 8 Hands-On Stations for Teaching Reflection, Refraction, and Absorption (TEKS 5.8C)

Chris Kesler · 8 min read

Drop a straw in a glass of water and watch it appear to bend at the waterline. That bend isn't real. The straw is still straight. But the light coming through the water is doing something to your eyes that you've ignored your whole life until someone points it out. 5th graders have seen this a hundred times in cups and pools, and never once asked why. Now they will.

That's TEKS 5.8C. It asks 5th graders to demonstrate how light travels in a straight line and how it is reflected, refracted, or absorbed when it interacts with different materials. They have to recognize transparent, translucent, and opaque materials. They have to predict what a flashlight beam will do when it hits a mirror, a glass of water, or a black piece of paper.

The How Light Travels Station Lab for TEKS 5.8C turns each of those into a hands-on test. Kids shine a flashlight at a mirror and watch the beam bounce. They put a paper of arrows behind a glass of water and watch the arrows flip and warp. They hold plastic wrap, wax paper, and black construction paper up to a flashlight and rank them from "see everything" to "see nothing." By the end, they can sort materials into transparent, translucent, and opaque, and they can explain in their own words why the straw looks bent.

8 hands-on stations for teaching how light travels

A station lab is a student-led activity where small groups rotate through 8 stations (plus a 9th challenge station for early finishers) at their own pace during one to two class periods. You become a facilitator instead of a lecturer. You walk around, spot-check, and break misconceptions while kids work through the rotation.

The How Light Travels Station Lab has four input stations (where students take in new information on reflection, refraction, absorption, and how materials affect light) and four output stations (where they show what they learned). Here's what's at each one.

4 input stations: how students learn how light travels

🎬 Watch It! —

A short YouTube video introduces reflection, refraction, and absorption with an alien scene and an ancient-Egyptian-mirror reference that catches 5th graders off guard. Three questions on the answer sheet check the big ideas: why the alien appears green, why ancient Egyptians used mirrors to reflect sunlight deep into stone buildings, and why light waves bend when they travel through a new material. The Egyptian-mirror question is the one kids will bring home to their parents.

📖 Read It! —

A one-page passage called "From Darkness to Light: Reflection, Refraction, and Absorption" opens with a kid stubbing their toe on a toy truck in a dark hallway and uses that to set up the question of WHY we need light to see. The passage walks through light traveling in a straight line until it hits something, then breaks down reflection (mirrors vs. crumpled foil), refraction (the straw-in-water example), and absorption (opaque walls vs. transparent glass vs. translucent frosted glass). Vocabulary is bolded throughout (reflection, refraction, absorption, opaque, translucent). Three multiple-choice questions follow, plus the vocabulary section. Comes in two reading levels (Dependent and Modified) plus a Spanish version.

🔬 Explore It! —

This is a three-part hands-on station and it's the heart of the lab. Part 1 (Reflection): students shine a flashlight at a mirror with a white piece of paper in front of it, watch the beam reflect, then rotate the mirror and watch the beam shift. Part 2 (Refraction): they fill a glass with water, place a paper with arrows behind the glass, and slowly move the paper up and down to watch the arrows flip and warp as they cross the waterline. Part 3 (Absorption): they hold plastic wrap, wax paper, and black construction paper next to each other and shine a flashlight through each, then categorize each as transparent, translucent, or opaque. Six questions total. Kids who never volunteer in class won't stop talking at this station.

💻 Research It! —

Ten reference cards visualize what's hard to see: light reflecting off a mirror in a clean V, light absorbing into a red strip and turning into heat energy, a prism splitting white light into a rainbow, and color squares showing exactly which color is reflected and which are absorbed (a red square reflects red and absorbs the rest). The HOW WE SEE COLOR card and the black-shirt-feels-hot-in-the-sun example are the ones to watch. Four questions tie it all together: compare smooth shiny surfaces to a prism, explain why a red apple appears red, predict what would happen if white light hit a black object vs. a white object, and explain how reflection, refraction, and absorption together explain a rainbow.

4 output stations: how students show what they learned

📋 Organize It! —

A three-column term-definition-picture sort. Six terms (reflection, refraction, absorption, transparent, translucent, opaque) get matched with their definition AND a small diagram. Reflection matches "light bouncing off an object at the same angle it struck the object" plus an arrow diagram. Refraction matches "light bending as it passes through an object." Absorption matches "light staying inside an object." Transparent shows clear cows visible through windows; translucent shows the same cows but blurred behind frosted glass; opaque shows red curtains that block everything. Forces kids to match three pieces, not two, and confirms whether they really understand each idea.

🎨 Illustrate It! —

Students draw a quick sketch showing all three ways light interacts with a medium, with each labeled: reflection, refraction, absorption. Most kids draw a flashlight aimed at three different objects: a mirror (with the beam bouncing off), a glass of water with a pencil in it (with the pencil appearing bent), and a black square (with the beam disappearing). The labeled drawing is the easiest tool for review — kids can look back at their own sketch and explain it.

✍️ Write It! —

Three open-ended questions in complete sentences. First, explain why you can see your reflection in a mirror but not on a wall (smooth vs. rough surface reflection). Second, how different materials (transparent, translucent, and opaque) affect the way we see objects, using evidence from the Explore It! activity. Third, how the color of an object (red apple, black shirt) affects how much light it reflects or absorbs. The black-shirt question is the one to watch because it ties absorption directly to a real-world thing every 5th grader has experienced — the black shirt that gets unbearably hot in the sun.

📝 Assess It! —

Three multiple-choice questions plus a fill-in-the-paragraph that uses the five Read It! vocabulary words (reflection, refraction, absorption, opaque, translucent). The multiple choice covers the definition of absorption, what happens when a flashlight hits a mirror, and which of four materials allows the most light through (a wooden door, frosted glass, clear plastic wrap, or black construction paper). The paragraph uses a decorate-your-room scenario with a frosted glass vase, a mirror, a dark wall, bookshelves, and a glass ornament to weave all five vocabulary words together. If you're grading the lab, this is the easiest station to grade.

Bonus Challenge It! station for early finishers

🏆 Challenge It! —

Four optional extensions: create a flipbook animation of a light ray reflecting, refracting, and absorbing (with a how-to website provided); create a four-panel comic strip illustrating the behavior of light using every Read It! vocabulary word; complete an interactive online light activity at primaryschoolscience.co.uk and show the "unlocked all items" screen; or pick one technology (reading glasses, telescope, microscope, camera) and research how it uses reflection, refraction, or absorption. Requires teacher approval before they start.

How this fits into a complete How Light Travels unit

This Station Lab is the Explore day of our full How Light Travels Complete 5E Lesson for TEKS 5.8C. The complete two-week unit follows the 5E method of instruction and includes an Engage hook, the How Light Travels Station Lab for Explore, PowerPoint slides and interactive notebook pages for Explain, student choice projects to Elaborate, and an Evaluate assessment.

Most 5th-grade teachers grab the full 5E because the Station Lab lands hardest with the days around it. But if you just need a strong hands-on day on light and how it interacts with materials, the Station Lab on its own does the job.

Materials needed to teach how light travels

Materials beyond what's in the download:

1 small flashlight per group for all three parts of the Explore It! station. A dollar-store LED flashlight works fine; phone flashlights work in a pinch but eat your students' attention.
1 small mirror per group (a stand-up makeup mirror or a hand mirror flat on the table both work).
1 clear glass cup per group for the refraction activity (a clear plastic cup also works).
1 sheet of white paper per group for the reflection backdrop, plus 1 printed paper with arrows on it for the refraction observation.
A small square of plastic wrap, wax paper, and black construction paper per group for the absorption sort.
Colored pencils or markers for the Illustrate It! station.
Pencils and the printed answer sheets (included)
A device with internet for the Watch It! station

Common student misconceptions this lab fixes

"Light is just there. It doesn't actually move from one place to another."
5th graders treat light like air — present everywhere all at once, no source needed, no path. The Read It! passage names it directly: light travels in a straight line from a source until it reaches an object. The Explore It! reflection activity makes the path visible. When you shine a flashlight at a mirror with a white sheet of paper in front, you see TWO clear straight lines: one going in to the mirror and one coming back out. Rotate the mirror and the reflected line moves to a brand new spot on the paper. The light didn't "appear over there." It bounced from here to there along a path you can see. By the time they hit the Assess It! questions, they can predict where a beam will land before turning the flashlight on.
"Mirrors are special. They reflect light, but other things don't."
Kids think reflection is a property of mirrors alone, and that walls and clothes just "are colors." The Research It! HOW WE SEE COLOR card flips this idea. A red apple looks red because it reflects red light AND absorbs every other color. A black shirt looks black because it absorbs ALL colors. EVERY object you see is reflecting some light (otherwise it would be invisible). The Write It! mirror-vs-wall question makes the distinction sharper: mirrors reflect light in a clean predictable pattern because they're smooth and shiny, so you see a full image. Walls reflect light too, but they scatter it in many directions because they're rough, so you only see the wall (not your face in the wall). Same process, different surfaces.
"If a material is "see-through," all light passes through it the same way."
5th graders use "see-through" as a single category. The Explore It! absorption activity splits it into three sharp categories with three real materials in their hands. Plastic wrap: shine the flashlight through it and you can read text on the other side (transparent — almost all light passes through, objects clear). Wax paper: shine the flashlight through it and you see a blob of brightness but no detail (translucent — some light passes through, objects blurry). Black construction paper: shine the flashlight at it and you see nothing on the other side (opaque — almost no light passes through). The Organize It! card sort confirms it with three diagrams (clear cows visible, blurred cows behind frosted glass, red curtains that block everything). By the end, "see-through" is replaced with three precise words.

Tips for teaching how light travels in your 5th grade classroom

Two things make this lab go smoother the first time:

1. Dim the lights for the Explore It! station.

The reflection and absorption demos pop ten times harder in a darkened room. Bright overhead lights wash out the flashlight beam and the refraction effect on the arrows is much harder to see. Pull the blinds, kill the overheads, and let the flashlights do the work. If your classroom has a corner that's already darker, set the Explore It! station up there. The wow-factor difference is worth the 30 seconds it takes to flip the switch.

2. Pre-print the arrows page for refraction.

The refraction activity needs a piece of paper with clear arrows pointing left or right placed behind the glass of water. The cleaner the arrows, the sharper the warp effect. Print one master page with three or four large arrows pointing in different directions, copy enough for every group, and store them with the station kit. Don't ask kids to draw their own arrows in the moment — you'll lose 10 minutes of station time to debating which way the arrow should point.

Frequently asked questions

What does TEKS 5.8C cover?

Texas TEKS 5.8C asks 5th grade students to demonstrate how light travels in a straight line and how it is reflected, refracted, or absorbed when it interacts with different materials. Students should be able to predict what happens when a beam of light hits a mirror, a glass of water, or a dark surface; identify materials as transparent, translucent, or opaque; and explain why we see colors (reflection of one color, absorption of the rest).

What's the difference between reflection, refraction, and absorption?

Reflection is when light bounces off an object (like off a mirror or a wall). Refraction is when light bends as it passes through a new material (like the straw appearing bent in a glass of water). Absorption is when light enters an object and stays there, usually turning into heat (like a black shirt warming up in the sun). The Read It! passage and the Research It! cards walk through each one with diagrams and real examples.

How long does this How Light Travels activity take?

One to two class periods (45 to 110 minutes total). The Explore It! station has three parts (reflection, refraction, absorption), so plan for two periods the first time you run a station lab. Once your class has the rotation routine down, most groups can finish all 8 stations in one period.

Do I need expensive lab equipment for this?

Not at all. A dollar-store flashlight, a small mirror, a clear cup, a sheet of paper with arrows, and three textures of paper (plastic wrap, wax paper, black construction paper). Total cost for a class of 30 in groups of 3: under $15. Everything else (pencils, markers) you already have. Phone flashlights work as a backup if a kid's flashlight battery dies.

Can I use this in a 1:1 digital classroom?

Yes. The full digital version (PowerPoint or Google Slides) works in 1:1 classrooms and Google Classroom. Students drag digital term-definition-picture cards at the Organize It! station and type their answers. The Explore It! flashlight activities are harder to digitize, but the primaryschoolscience.co.uk interactive in the Challenge It! station (also free online) lets kids drag light through materials and watch the results.
