Earthquakes and Safe cities 4 all with STEAM
Abstract

Greece ranks sixth in the most seismic countries in the world. During this educational scenario, students build their own seismograph by programming their BBC micro:bit (pocket-sized computer) to detect and react to earthquakes. They are introduced to the concepts of acceleration, velocity and gravity, acquire a basic understanding of earthquakes and realize how seismologists are analysing data. Using the micro:bit built-in accelerometer sensor, they record the magnitude of an earthquake. Each time an earthquake is detected, the micro:bit responds in various ways: lights up the led panel according to the intensity of the earthquake, creates a plot graph as a graphical representation of the earthquake’s vibrations, triggers a sound and visual alarm. They learn how to use technology (Tech4good) to solve major challenges like natural disasters (SD Goal 11: Sustainable cities and communities). Students also realize the importance of designing inclusive solutions by taking into account people’s disabilities: visual or sound alarm for people with visual or hearing impairment (SD Goal 10: Reduced inequalities). The activities of this educational scenario were implemented during the eTwinning project "Micro Circuits for Mega Solutions".

Description of the practice

First, the students recall their prior knowledge of Earthquakes and start investigated the causes of earthquakes and their impact on the geology of an area and on human societies. Then, through playful activities, they are introduced to the concepts of acceleration, velocity and gravity and they are asked to figure out, how technology and more specifically the BBC micro:bit could be used to detect and react to natural disasters like earthquakes.

 

Using the micro:bit built-in accelerometer sensor, the students measure the Earth's acceleration. When an earthquake is detected, the students program their micro:bit to:

a) light up the led panel according to the intensity of the earthquake.

b) simulate a seismograph by creating a plot graph as a graphical representation of the earthquake’s vibrations.

c) trigger a sound and visual alarm to warn people with visual and hearing disabilities.

Finally, the students create buildings from cardboard and other recycling materials to build a model city and simulate an earthquake using the BBC micro: bits as seismographs. They are working in teams of 3 or 4.

IMPLEMENTATION

Because of Covid19 issues, some activities were implemented both in-class and in remote teaching.

1rst didactic hour:

Brainstorming and discussion: the teacher introduces the topic of the learning scenario which is how we can use technology and more especially the BBC micro: bit controller to detect and measure an earthquake. The problem they have to solve is “We are living in one of the most seismic countries in the world. How can we use technology to detect an earthquake at its beginning, and trigger an alert to the population?” The teacher has mostly the role of the facilitator and encourages them to try to answer questions like (Inquiry-Based Approach): How can an earthquake happen? Where can it take place? How do we know about its magnitude? Is there any way to be prepared? How can we notify people before the main earthquake and protect them? Interdisciplinary activity between the teachers ICT and geography.

2nd didactic hour:

The students are working in teams and each team has to answer some questions (What makes an earthquake happen? Why are some regions more seismogenic than others? What impact do earthquakes have on human lives, on the economy and on nature? How can we better understand and predict these sometimes deadly events?) and add their responses to a collaborative online padlet. They can use educational resources their teacher had already prepared or search by themselves on the web.

3rd didactic hour:

The students are introduced to the notions of acceleration, velocity and gravity, by using everyday examples. Each team uses a cabriolet car toy and a human toy figure (the driver) to help them experiment on velocity and acceleration. In plenary, each team tries to complete an online collaborative mind map with the help of the teacher is needed.

The students are working in teams in the computer lab. They have a micro: bit and are connected to the online micro: bit online classroom, created by the teacher. They are using the MakeCode blocks editor. The first task is common to all groups: they have to experiment with the accelerometer sensor and the input value “Acceleration (mg) Strength”. At this point, the teacher helps them make the connection (by asking questions) between earthquakes and acceleration. The students connect their micro:bit to the computer, shake it and make the micro:bit panel display the strength of the earthquake magnitude in mg. The students take notes of those values on a paper manually. The students realize that the 2000 mg is the maximum acceleration that the micro:bit can record and that 1023 mg is when it doesn't move at all, but still has an acceleration because of the Earth gravity.

4th didactic hour: 

Each team has to design an inclusive solution for people with visual and hearing disabilities: they have to code their micro:bit to trigger a visual or a sound alarm when it detects an earthquake.

In class implementation:

micro:bit light alarm

micro:bit sound alarm

5th-6th didactic hour:

The students are introduced to the command “serial write value” which reads the acceleration values on the micro:bit in real-time and creates a plot graph as a graphical representation of the earthquake’s vibrations. The students experiment with this new command and realize how seismologists are interpreting the seismograph results and how easier is to understand a graphical representation instead of numbers are those they had written on paper (3rd didactic hour).

Next, the students work in teams using the radio control of their micro:bit to send remotely an alarm message from one micro:bit to another. Some teams choose to program the sender micro:bit and some others the receiver one.

Remote teaching implementation, co-teaching:

7th didactic hour:

Students have created buildings from cardboard and other recycling in collaboration with their art teacher. Each team adds its micro:bit on the roof of its building and simulate an Earthquake. The micro:bits are acting as seismographs and the students reflect on the output results, trying to make a connection between the acceleration and the height and the materials of the buildings. 

 

EVALUATION

During the entire project, the students were assessed using formative as well as summative assessment. The formative assessment takes place in the form of a survey, a mindmap, a digital wall, through the learning products, or quizzes with the purpose of gathering information if all learning outcomes are achieved (Kahoot quiz on earthquakes,  Quizizz quiz on Micro:bit programmingMindmeisterMind Map on Acceleration, GravityPadlet to reflect on earthquakes ). At the end of the project, students and teachers complete some questionnaires, as feedback ( student1, student2, teacher)

 

LESSONS LEARNED:

At the end of this project, the students learned how to use technology to solve real-life problems. They had a better understanding of earthquakes (causes and effect), understand by experiments the concepts of acceleration, velocity and gravity. They develop critical thinking and computational skills through designing, programming, inquiring and exploring, improved their communications skills practising collaborative learning and realized the need of designing inclusive solutions.
