DaVinci Kindergarten

DaVinci Kindergarten is a pilot project in which we design, develop and try-out inquiry-based activities for children in the age 4-8. We have worked with children age 4-5 at two kindergartens in Norway. The activities focus on concepts from science, and technology and foster mathematical thinking.

We present some of the activities that have been developped. Contact us if you wish a complete description of the activity.

  1. Show-box– sight lines and mirroring.
  2. How big is the panther? – measuring, human-based measuring units e.g. foot, thumb(=duym/inch), span (=fathom), step.
  3. How do you get the light on? – electricity, battery, light, lightbulb, lamp, electrical wire, curcuit.
  4. What weighs most/least? – experimenting with balance scales and different materials with the same volume and different weight.
  5. Discover more about your toys. What kind of materials are they made of? – Categorise, recognise, examine the different materials and discover their characteristics.
  6. Bee-bot – programming a robot.

Solubility in water

Water is the most important chemical substance on earth. Water has specific chemical characteristics unlike other substances. One of these characteristics is its solubility.

Students build an understanding of solution concentration by varying amounts of solute,
solvent, and solution. Students can investigate which substance can have the largest concentration (solves best) even if they do not know  the substance. This can be an introduction to a hands-on practical.

The students can observe the amount of mol/L (molecules that can be solved in one litre) and find out what saturated means? What can be observed when the solvent is saturated?

Depending on how used the pupils are to carry out experiments, you can leave out some of the instructions (scaffolding). Purely inquiry-based would be:

  • Find out how you can influence the degree of solubility in water using the effervescent tablets and water.

Whereby the pupils have to set up the experiment themselves, record the results, and write a conclusion.
