Step-by-Step Guidance
1. Prepare the space on a wipe-clean surface, placing a spill tray or mat underneath where the tray will sit. Set out aprons and cloths within adult reach.
2. Pre-mix coloured water in clear, unbreakable jugs or bottles using a small amount of food colouring. Use only a few colours to start, keeping the liquid level low to reduce spill risk.
3. Place the empty ice cube tray in the centre. Put pipettes beside it, and position the coloured water slightly to the side so the adult can control access if needed.
4. Share Mouse Paint briefly, pausing on pages where colours are shown clearly. Keep the reading short so children can move into exploring without waiting.
5. Invite children to choose a colour to add to one section of the tray. Model how to draw up liquid and release it slowly into a single compartment, using calm, minimal demonstration.
6. Offer the book nearby so children can refer back to it. Some children may match the story colours; others may choose their own combinations.
7. As children add a second colour to a compartment, allow time for them to watch the change. Support them to keep some compartments as “single colours” for comparison if they choose.
8. If children want to change a colour again, offer a way to rinse the pipette or provide a second pipette, depending on what you have available. Keep the focus on noticing rather than producing a perfect result.
9. Use simple language to name what is happening (for example, colour names, lighter/darker, more/less). Avoid over-directing; follow children’s experiments.
10. Close the activity by helping children decide what to do with the tray (leave it to observe, tip away with adult support, or photograph the tray for later discussion). Wipe the surface together where appropriate.
Learning Objectives
Children may develop fine motor control as they squeeze and release a pipette with intention (Physical Development). Children may build early understanding of cause and effect and simple changes in materials as colours combine (Understanding the World). Children may extend colour vocabulary and talk about what they notice, linking ideas to a familiar story (Communication and Language; Literacy).
Adult Role
Stay emotionally attuned by keeping the pace unhurried and noticing when a child is frustrated by squeezing or waiting. Model language that matches what children can see, naming colours and simple changes, and reflecting children’s ideas back to them. Scaffold only as much as needed: demonstrate pipette control once, offer hand-over-hand support only with permission, and step back when a child is repeating an experiment independently. Observe closely for patterns in how children plan, persist, and compare results, and use those observations to decide whether to add complexity (more colours, fewer prompts) or simplify (fewer choices, larger droppers). Hold responsibility for safe handling of liquids, preventing mouthing, managing spills promptly, and keeping materials within safe reach.
Observation Cues
Selects a droplet size deliberately, watching until it falls before releasing more liquid. Pauses to compare two tray sections side by side, using gesture rather than words. Moves the tray closer or further to catch the light when checking a new shade. Links a colour mix back to a page in Mouse Paint without an adult prompt. Waits for a peer to finish before reaching for a jug, showing awareness of turn-taking.
