Material Properties: Waterproof and AbsorbentActivities & Teaching Strategies
Active testing lets Year 1 students connect abstract ideas to tangible experiences, turning observations of beads and soaks into lasting memories. When children handle real samples and see water behave differently, the difference between waterproof and absorbent stops being words and starts being evidence they can trust.
Learning Objectives
- 1Classify materials as waterproof or absorbent based on experimental results.
- 2Compare the properties of different materials in relation to their ability to repel or absorb water.
- 3Explain why specific materials are chosen for products based on their waterproof or absorbent qualities.
- 4Design a simple experiment to test the waterproofness of a given material.

Stations Rotation: Water Drop Tests
Prepare stations with materials like tissue, foil, cotton, and plastic. Students drop water from a dropper, time absorption or repulsion, and record with tick charts. Rotate groups every 7 minutes for all tests.
Prepare & details
Explain why some materials are waterproof and others are not.
Facilitation Tip: During Station Rotation, place identical droppers and wipe cloths at every table so students focus on the material, not the tool.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Pairs: Fair Test Challenge
Pairs select two materials, predict outcomes, then test by adding equal water drops on identical samples. They swap results with another pair and discuss fairness. Extend by grouping materials.
Prepare & details
Compare materials that absorb water to those that repel it.
Facilitation Tip: During Fair Test Challenge, ask pairs to swap roles after one test so each child pours and records.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Whole Class: Use-Matching Sort
Display tested materials and pictures of uses like umbrellas or towels. Class votes and sorts into waterproof or absorbent piles, justifying choices. Record on a shared chart.
Prepare & details
Design an experiment to test if a material is waterproof.
Facilitation Tip: During Use-Matching Sort, have students place their matched pictures on a class Venn diagram to highlight overlaps and differences.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Individual: Prediction Sheets
Each student draws three materials, predicts water behaviour, tests alone, then colours results. Share one surprise in a circle talk.
Prepare & details
Explain why some materials are waterproof and others are not.
Facilitation Tip: During Prediction Sheets, model a think-aloud for the first sample so students see how to link prediction to observation.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Teaching This Topic
Start with a quick story about a soggy sock versus a dry umbrella to create an emotional hook, then let the materials do the teaching. Avoid long explanations; instead, prompt students to compare what they see with what they predicted. Research shows that when Year 1 learners articulate their observations aloud and hear peers confirm or challenge them, misconceptions fade faster than when teachers explain first.
What to Expect
By the end of the station work, every child will confidently point to a material and say whether it repels or absorbs, using simple vocabulary like bead, soak, and drip. They will also match the property to a real object because they have tested and discussed it themselves.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Station Rotation, watch for students who assume that shiny materials are always waterproof.
What to Teach Instead
Place both foil and shiny paper at one station, have students drop water on each, and ask them to describe the bead on foil versus the immediate soak on paper. Prompt them to compare appearance to evidence before they move on.
Common MisconceptionDuring Fair Test Challenge, watch for students who say absorbent materials drink water like people.
What to Teach Instead
Ask pairs to look closely at the paper towel sample while water soaks in, then sketch the fibres with arrows showing water filling the spaces. Label the arrows so students see water moves between fibres, not into a mouth.
Common MisconceptionDuring Use-Matching Sort, watch for students who believe thicker items are automatically waterproof.
What to Teach Instead
Include a thin plastic bag and a thick cloth square in the mix. Ask students to place each in the correct circle and explain why thickness alone does not decide the property, using the evidence from their tests.
Assessment Ideas
After Station Rotation, give each student three small samples (plastic wrap, paper towel, fabric swatch). Ask them to predict waterproof or absorbent, test with a few drops, and record with simple drawings or words to check their ability to apply the property labels.
After Use-Matching Sort, show pictures of a raincoat, sponge, and plastic bag and ask students to explain why each material is right for its job using the new vocabulary.
After Prediction Sheets, give each student a slip to draw one waterproof item and one absorbent item, then write the property word under each drawing to assess individual understanding.
Extensions & Scaffolding
- Challenge: Ask early finishers to test a fourth material, such as waxed paper or burlap, and draw a simple bar graph with ticks for waterproof or absorbent.
- Scaffolding: Provide picture word banks on Prediction Sheets for students who need writing support.
- Deeper exploration: Introduce a second drop after three minutes to see if any material changes from absorbing to repelling or vice versa, prompting students to think about saturation.
Key Vocabulary
| Waterproof | A material that does not allow water to pass through it. |
| Absorbent | A material that soaks up liquids, like water. |
| Repel | To push away or resist something, in this case, water. |
| Soak | To absorb liquid completely. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
