A flashlight, three materials, and one fair comparison
An adult places a flashlight on a table facing a white card. A child observes the lit patch on the card, then predicts what will happen when a sheet of clear plastic, wax paper, or cardboard is placed between the flashlight and the card. Keep the light and card in the same positions. Aim the flashlight at the card, away from faces.
Explain the result
In this worked example, clear plastic lets a bright patch remain visible. Wax paper lets some light through but spreads it, making a less distinct patch. Cardboard blocks the beam and makes a dark area on the card behind it. The difference concerns how light passes through each material. The card is visible because light reaches it; opening our eyes does not create the light. Record what your own materials actually do rather than copying these expected observations.
What to check in the explanation
A dark area behind cardboard does not mean the flashlight stopped working. Remove the cardboard and check whether the bright patch returns. If the child changes the flashlight distance for each sheet, repeat the comparison with the distance held steady. Material thickness and surface can affect the result, so do not treat every kind of plastic or paper as identical.
Plan the next activity
- Draw the setup and predict which sheet will leave the brightest patch.
- Place one sheet in the beam at a time and record bright, dim, or blocked light in a simple table.
- Remove the sheet and repeat the baseline observation before testing the next one.
Ask the child to explain which material would work for a window and which would help make a shadow screen. Point to the observation that supports each choice. Later, compare a second sample of the same material to see whether its thickness changes the result. This activity introduces observation and comparison without requiring calculations about light speed.

How does Grade 1 science connect to ATLAS?
Grade 1 is outside the older-grade ATLAS science program. Early-grade literacy and mathematics assessments are separate. The activities and quizzes here are independently published learning resources, not official state assessments. Consult the school and state guidance for testing arrangements. Read the official guidance.
Why keep the flashlight and card in the same places?
Keeping the setup steady helps us compare the effect of the material. Changing distance and material at the same time makes it harder to tell what caused a different patch of light.
