Primary science when equipment, devices or preparation time are limited

Not every worthwhile investigation needs a cupboard full of equipment. Bottlebrush includes no-materials activities and classroom experiments with everyday items—but teachers should still check setup, safety and how students will record evidence.

No-materials activities in the catalogue

Currently 82 of 147 lessons are marked “No materials needed” in the lesson data. This label refers to hands-on equipment: a digital activity may still require an iPad or a shared classroom display. Check the topic and lesson before teaching.

If my class shares one iPad, what works?

Project one source, simulation or data comparison so pupils can predict the result and propose the next trial. Pause before revealing a conclusion, then record predictions, data and explanations on paper. A shared-device method must be appropriate for the lesson; not every interactive task is automatically equivalent.

If there are no student iPads, what works?

Choose activities supported by printed records, teacher demonstrations or simple materials. Use the public topic list to check the lesson requirements. A source-comparison lesson can be completed in exercise books, whereas a digital-only investigation requires an alternative planned by the teacher.

What should a relief or time-poor teacher check first?

Read the key question, method, materials, safety notes, expected evidence and independent exit question. Allow time for students to explain the science; adding more worksheets is not the same as improving scientific inquiry.
