(12 to 15 year olds)



Age-group: 12-15 years old

Number of hours: 20 hours


Short description of activity: 


In this multi subject project students will research the usage of energy around the world and in their own country. Students innovate smart solutions to save electricity and design smart spaces in which these solutions will be implemented.  




Data collection and Analysis









  • -Students learn and understand why it is important to save energy and how it is possible via everyday choices. Students are challenged to ponder how much electricity is being used in different parts of the world.

  • -Students find out, learn and understand renewable energy sources as part of an electricity production. 

  • -Students learn how to calculate the amount of used electrical energy, how much does it cost in different countries and how much money you can save by using smart solutions.

  • -Students learn and understand the meaning and importance of saving energy via everyday life actions.

  • -Students learn to design, build and code simple automated smart solutions which tackle the problems introduced in the project


Realistic STEAM-context




Part 1 - Introduction - Lights from space (Timing 1h)

Multi subject: Science


Lights From Space


Teacher introduces a map of the earth shot at night. Guided discovery. What do you see? How come there is light on some parts and not on the others? Is this sustainable, what could be done? See Appendix 1


Why is it important to save energy?


Discuss the importance of saving energy and the fact we have only one earth -> sustainable energy usage in everyday life

Part 2 - Cost and expanditure of electricity  (Timing 1hr)

From this part onwards students will be divided into small groups.

Multi subject: Science/Math

Students will learn about electrical energy: how to calculate the amount of used electrical energy, how much does it cost around the world and in their respective country and how much money you can save by using smart solutions. See appendix 2.

Part 3 - How to save electricity in everyday life at school/home (Timing 1hr)

How to save electricity in everyday life at school/home

Multi subject: Math/Science


Students work in groups and find ways to save electricity in everyday life.


See appendix 3.

Part 4 - Microbit - Introduction (Timing 1hr)

Multi subject: Science/Arts and crafts

Teachers’ note: the smart solutions in this project are designed to be implemented with microbit microcontroller. If your school doesn’t have microbits you can simulate everything from this project in

Teacher introduces microbit and students do exercises on how to use it and how to measure light level. See Appendix 4.

Part 5 -Designing the space (Timing 1hr)

Multi subject: Science/Arts and crafts


Students need to design a miniature space in which the energy saving automated solutions will be implemented (smart lighting is the minimum requirement) 


See appendix 5.

Part 6 -Building the space (Timing 2-3hrs)

Multi subject: Science/Arts and crafts


Any material can be used (cardboard, clay etc.) in the building process. 3D-designing & printing furniture is also possible, but furniture can also be built out of traditional materials (cardboard, wood).


When building it’s important to think & plan how to implement smart solutions. 

Building may require extra time.

Part 7- Automated smart solutions (Timing 2-3hrs)

Integrating automated smart solutions.

 See appendix 6 & 7.

Part 8 - (Optional) Timing 2hrs)

(Optional) Integrating other smart solutions, automated window or door or fan

See appendix 8.

Part 9 - Testing and debugging (Timing 2hrs)

How to code, do you have to change code to get the effect you require?

Example: Lights go on too early, change the light level on which lights go on

Part 10 - Implementing changes (Timing 2hrs)

Part 11 - Presentation and feedback (Timing 2hrs)

See Appendix 9?


Students make an expedition for the school and give a tour of the space. Students make a presentation for example with imovie or a virtual tour




  • wood, plastic, cardboard, straws, wire, servos, electric motors, LEDs, popstickels, batteries, hot glue, tape, 


Use of ICT: 


Microbit for coding of smart solutions, 3D printing for printing parts and furniture (not necessary), makey makey, scratch, project can be implemented without any of the previous but we recommend using microbits. If the school doesn’t have microbits everything involving them can be simulated in 


Opening of classroom:


Useful questions: 

  • 1. Introduction/Lights From Space

  • See Appendix 1


  • 2. Cost and expenditure of electricity

  • See Appendix 2

  • 3. How to save electricity in everyday life at school/home

  • Are the lights on unnecessarily at school or home?

  • What kind of solutions do you already know for saving electricity?

  • How do the automated solutions work? What do they measure?

  • 4. Microbit introduction

  • 5. Designing the space

  • What is the space like? Room, house, road, public space, treehouse, castle? Open or closed?

  • How big is the space?

  • What materials will be used?

  • Is there any furniture etc. in the space?

  • What automated smart solutions will be implemented and how?

  • 6. Building the space


  • 7. Automated smart solutions


  • 8. Optional part


  • 9. Testing and debugging


  • 10. Implementing changes


Stimulation of self-management: (concrete opportunities/remarks adapted to the project)


Stimulation of cooperation: (concrete opportunities/remarks adapted to the project)

  • Teamwork: 

  • Groups consist of 3-4 students. 

  • Competences needed in a group:

  • Decide responsibilities


  • Builder

  • Coder

  • Documenting

  • 3D-designer


Students have the chance to assign responsibilities for each other. Giving students specific roles and responsibilities assures that every part of the project has a student taking care of that part.


Formative assessment: (concrete description/summary adapted to the project)


Data collection and Data analysis:

  • find out the true cost of electricity in your country

  • measuring light levels in different conditions and collect data


  • energy expenditure


  • lights from space, analysing what is shown in the picture. What is similar for the places that are well lit


  • microbit


  • find errors in microbit coding




-Documentation using for example keynote, powerpoint or imovie. Exhibition of the finished spaces.



  • General ideas: Advanced students can design their own smart solutions with motors, servos and LEDs

  • Ideas with younger/older children: (3-6 <-> 6-9 / 9-12 <-> 12-15)

  • Use only minimum requirements (smart lighting). Give easy to assemble parts for the building. Coding is optional, code can be provided partially. If your school doesn’t have microbits, can be used to virtually simulate microbits or simulated with
