Real- life questions

We unconsciously use many disciplines together to solve a problem in our daily life. While teaching at school, we should not ignore interdisciplinary learning. With this learning scenario, Science and Information Technologies lessons were integrated and used. While sustainability and efficient use of resources are discussed in Science, they will be able to measure how much water a plant needs with coding in Information Technologies.
• Can you determine the water requirement of a plant by coding?
• What can the hygrometer be used for in daily life?
• In which parts of your house do you save water the most?

Course Goals

• Contributing to the efficient use of resources.
Informatics (ICT)
• Coding with Arduino.
• Measure the moisture of your soil with a hygrometer.


The teacher makes the students watch the 25 Lt documentary below.

The following questions are asked to the students in order to determine the readiness level of the students. Brainstorming is done by collecting the answers from the students.

  1. Why do you think water is so important?
  2. Do you think that water resources are used sparingly in our country?
  3. What problems can a decrease in potable water cause?
  4. What can be done to reduce water use in agriculture?
    The teacher said to the students who answered the questions, “Imagine you are an agricultural engineer. Can you design a device that will reduce water use in agriculture and provide efficient irrigation?” The problem situation is given.


Students were asked to conduct research on sustainable development and the efficient use of resources anAt this stage of the learning scenario, the students did research on sustainable development and the efficient use of resources. They gathered the information they obtained on the Canva Web 2.0 tool.


At this stage, students explain the subject by presenting the data they have collected in the class. The teacher fills in the missing parts of the students.


The world population is increasing rapidly and with it, the need for energy is also increasing. Conscious use of resources in order to meet the energy needs of future generations is called sustainable development. It is aimed to prevent the exhaustion of natural resources without ignoring today’s needs. Sustainable development has two main pillars. The first of these is the efficient use of resources and the other is recycling.


At this stage, students’ science, technology and engineering disciplines are integrated. Students will look for solution suggestions suitable for the problem situation and present their solution suggestions to their teammates. The most appropriate solution proposal will be selected by the teams. Here, our students have chosen to develop an irrigation system with Arduino as a suitable solution to the problem situation. In the system created by the students, watering is done when necessary by measuring the soil moisture with the soil moisture sensor.In the created setup, students used soil moisture sensors. They measured the soil moisture and watered when necessary.

Sketching the design and creating its three-dimensional version

Here, our students draw attention to the efficient use of water. Students first drew their prototypes in 2D and then designed them. For the irrigation system, our students wrote codes and built a circuit on Arduino. Science and technology integration is provided here.


The students presented the prototype they created to their friends in the classroom. At the end of the presentation, the teacher evaluated the product and process of the students with the rubric he prepared. The irrigation system created by our students was presented at the TÜBİTAK 4006 Science Fair.
