Hands-on science
Science activities for every age
Each activity lists its recommended level, estimated time, and a checklist of common household and classroom materials. Every step favours careful observation over demonstration alone.
Scientific method
How an investigation unfolds
01
Hypothesize
Ask a precise question and write a prediction before starting. Learners state what they expect to observe and why.
02
Assemble materials
Gather the listed materials and set up identical conditions. Keep one variable to change and note everything else.
03
Conduct trials
Run the test several times, at the same time of day when possible. Repeated trials make results easier to trust.
04
Record data
Note measurements, drawings, and observations in a table. Compare the results with the prediction, even when it was wrong.
Activities by theme
Three investigations to try this week
Each activity suits a specific age bracket and requires only everyday materials. Check the level and materials before you begin.
Level: primary grades
Seed germination rates
Time: about 2 weeks. Compare germination of beans kept in light, in darkness, and with varied water. Materials: bean seeds, damp paper towels, clear cups, a notebook.
Level: lower secondary
Soil composition jars
Time: 1 to 2 days of settling. Layer a sample of garden or park soil in water to observe sand, silt, and clay separate. Materials: a clear jar, soil, water, a ruler.
Level: upper secondary
Fossil casting
Time: about 1 hour, plus drying. Press a shell or leaf into modelling clay, then fill the impression with plaster to compare a cast with a real trace. Materials: modelling clay, plaster, a shell or leaf, water.
