Learning benefits
- 💡 This activity enhances observation skills as children carefully layer liquids and note their distinct boundaries. It fosters an understanding of basic scientific principles like density and immiscibility, while also refining fine motor control and patience through precise pouring.
Safety notes
- ⚠️ Adult supervision is required throughout this activity, especially with the use of rubbing alcohol, which is flammable and should not be ingested. Ensure children do not drink any of the liquids. If liquids get on skin, wash with soap and water; if in eyes, rinse thoroughly with water.
Cleanup
- 🧹 Carefully pour the rainbow tower liquids down the drain, rinsing with plenty of water. Wash all containers, spoons, and pipettes with warm soapy water. Wipe down the work surface and any spills immediately.
