Technology and Design

DiScoro writes about inquiry-based learning, digital resources, and ways to encourage higher-order thinking. We focus on STEM education and the use of technology.

This time we write about Technology & Design as a school subject or project for students (grade 6 to 10). In several countries Technology and Design has become a school subject.
Most commonly students work on a task during more than one hour. The tasks are interdisciplinary and require many different skills: planning, sketching, creativity, safety, use of tools, research , construction, experimentation etc.
Technology is not limited to the use of digital technology. Technology & Design tasks have a strong practical component and aim at problem solving skills. By nature the tasks are often low floor-high ceiling tasks. This implies that it is clearly understandable what the goal is, all students are able to get started (low floor). At the same time the tasks offer enough challenges and opportunities to dive deeper both in creativity as well as in complexity (high ceiling).

To make a plan is usually a step in the process. It is up to the teacher to ask for a report of the process or not. This can be written, visual, oral, with the use of multi-media (photos, video) or a combination.

Topics that could be part of Technology & Design are

    • design and create a rocking horse for children age 2-3
    • make a piece of household furniture using recycled materials
    • make a gripper stick for waste picking, or for elderly people at their homes
  • engineering (using concepts from chemistry and physics)

Technology and Design will certainly focus on the new economy where circular design and production, and no or minimal waste, are the ultimate challenges and goals.


Video Science

DiScoro writes about inquiry-based learning, digital resources, and ways to encourage higher-order thinking. We focus on STEM education and the use of technology.

Video Science produced by by Science House offers a large number of short videos on experiments. The videos focus mainly on chemistry, but some videos are about phenomena from physics or other science areas.
Students can watch the video’s or carry out the experiments themselves., although some experiments require substances or equipment that will not be readily available. For you as a teacher the videos may inspire you to let show students the experiments. Of course it is even more more interesting and instructive if the students carry out experiments themselves in class.

The future for industry and society lies in recycling, and even a step further ahead in cyclic production, and cradle-to-cradle production. Particularly interesting are therefore experiments such as “Green plastic” and “Recycling paper”.

The latest App (version 4.0) is designed for iOS 6. Unfortunately the App does not work on iOS 11. Hopefully this will be solved soon.

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.
