Grilli che c(a)ontano! (Crickets that sing/matter!)

A Multidisciplinary activity that involves the STEM disciplines

The focus is on the study of climatic factors and the causes leading to an increase in temperature. Age : 14-15 years STEM : math, science, biology, physics, English. Teachers: Mario Di Fonza, Sabrina Nappi, Rosanna Busiello, Josephine Iannone


Song of crickets First, the students listen to the cricket song Students answer questions :
  • Why do crickets chirp?
  • Did you know that only male crickets chirp?
Pupils take a quiz on
Possible answers: Crickets sing to…. 1. Call the female: male cricket’s challenge is to be loud enough to be heard 2. Courting ritual 3. Drive other males away. The song of crickets is the nocturnal soundtrack of our collective rural, suburban and even urban lives. Some other questions:

The species

Crickets are insects belonging to the orthoptera family, and as such they emit sounds called chirps.

The song of the cricket

The students listening with greater attention to the song of a cricket The most bizarre and interesting thing to observe is that this song is discontinuous and is related to the temperature. The temperature rises and you can hear the cries of crickets. The crickets “sing” rubbing their legs. The warmer the weather is, the faster they “sing”. The focus is on the study of climatic factors and the causes which are leading to an increase in temperatures as a function of the perceived chirps of crickets.

Thermometers of the poor

Crickets are considered the thermometers of the poor, an expression that comes from the observation that the chirping of these animals increases or decreases in relation to the temperature of the environment. Crickets are cold-blooded, which means they take on the temperature of their surroundings. The temperature rises and crickets chirp more easily. The temperature drops and the reaction rate of the crickets slows down, causing their chirping to decrease as well. The Engagement is curious and the students are invited to verify this discovery.

Investigation phase

In this paragraph, the Students are provided with data taken from a research carried out in 2007 in Boulder (Colorado, USA), and are asked if it is possible to find a relationship between the number of crickets’ chirps (f) and the location temperature (t).
The students analyze the data on the table and build a scatter chart by observing how the points are arranged through the use of google sheets, and discuss it in groups. The students, from reading the graph, create a mathematical model that relates the temperature to the song of the crickets: t = a ∙ f + b, number of crickets’ chirps (f) and the location temperature (t). The relation: t = a ∙ f + b gives the value of the correlation between the increase in temperature and the song of the crickets. Students write the equation of the regression line passing through the points in the graph and calculate the correlation coefficient.

Deepening on the blog

Dolbear’ s Law

From the analysis of the data, students move on to analyze Dolbear’ s Law in physics. Amos Dolbear, was a 19th century American physicist, professor and inventor who studied various species of crickets to determine the relation between the number of chirps per minute and the ambient temperature. In 1897 Amos published an article “The cricket as a thermometer”, where the formula is reported (Dolbear’ s Law): T = 50 + ((N – 40) / 4) , where T is the temperature in Fahrenheit degrees and N is the number of chirps per minute. The students convert Fahrenheit to Kelvin. They convert them to Celsius as an exercise too. Dolbear’ s law, applied to the chirping of crickets, allows us to estimate temperatures between 55 and 100 degrees Fahrenheit. On summer evenings the crickets feel at their best.

Deepening with the sciences

The students reflect on the question: What happens in human beings if the internal temperature increases? The consequence is the link between physics and the sciences: the heart beats faster if the internal temperature increases. Pupils are asked, in pairs, to determine and share their body temperature by measuring the frequency of heart beats per minute, taking into account the relationship between heart activity and the internal body temperature reported: Resting adult
Resting adult Fever inside the abdomen
with 70 beats per minute 37°C
with 80 beats per minute 37/38°C
with 90 beats per minute 38°C
with 100 beats per minute 38°C
with 110 beats per minute 39°C
with 120 beats per minute 40°C
Pupils discuss the table, observing how each degree Celsius of body temperature increase corresponds on average to 8 beats per minute increase in heart rate. In this way, the focus is on the study of climatic factors that increase temperatures. Exercises To get different results, the pupils tried to “warm up” by running or doing some physical exercise.

Deepening with the biology

The activity ends with the experimental part in biology which concerns the use of crickets to study the effect of temperature on the metabolism of cold-blooded organisms. Small insects have a trachea where diffusion occurs, carrying oxygen and removing the carbon dioxide necessary for cellular respiration. The students use the chemical reaction:   and the image: Students are asked to: – find the correlation between the two images; – specify the reactants of this reaction, and the products; – describe what they observe; – specify what are the factors that can slow down or speed up a chemical reaction, and explain why? On a padlet (, the students enter their thoughts.

CO2 and temperature

The purpose of the activity is to determine how the temperature affects the respiratory rate of crickets by monitoring the production of carbon dioxide with a CO2 gas sensor at different temperatures. The amount of CO2 produced will determine the effect of temperature on the metabolism of crickets. The outline of the procedure for monitoring data collection of cold, intermediate and hot temperatures is provided to students divided into groups. The students enter data into tables and create graphs to read, they focus on the study of climatic factors and the causes which are leading to an increase in temperature.

The outline of the procedure

The CO2 sensor must be connected to the data collection device. If your CO2 gas sensor has a switch, set it to “Low” (0–10,000 ppm) placement. Change the data collection rate to 0.1 samples / second and the data collection duration to 600 seconds. Weigh 10 adult crickets, in a 600 mL beaker and record their data in Data and Observations.

Data and Observations

Temperature (c °) Concentration (ppm / s) Respiration Rate (ppm/s/g)
Assigned range Current
Mass of crickets: 1.6g Student collect data as follows: 1st stage: The students, in the group, construct a graph and relate the measured CO2 concentration and temperature. 2nd stage: The students prepare tubs with water at different temperatures, and The groups collect data on respiration at 5–10 ° C, 10–15 ° C and 15–20 ° C. 3rd stage: The students prepare a water bath for the desired temperature. This ensures that the crickets will remain at a constant and controlled temperature. To prepare the water bath, get fresh water and ice. 4th stage: The students mix cold water and ice in a 1 liter beaker. The beaker is filled with approximately 600–700 ml of water. The thermometer is placed in the water. The breathing chamber is in the water. 5th stage: The students use a pipette to remove or add hot or cold water as needed. 6th stage: Record the water bath temperature in Data and Observations.


Grilli che c(a)ontano! is focused on the study of climatic factors and the causes that lead to the increase in temperatures, aims to sensitize pupils to the issue of climate change consequences of environmental conditions. Thanks to the use of the IBSE methodology, the pupils observed how mathematical relationships are concretely found in nature, or how life, as we know it, depends on physical and biological factors. The purpose of this activity is to provide evidence on how the effects of global warming can cause negative impacts on ecosystems and on the metabolic activities of individuals. Furthermore, the students reflect on the important theme of energy emitted by the sun that is captured from the planet Earth and used by individuals to produce energy and work (metabolism).

Şebnem Gençtürk, a science teacher, conducted this study with 10 teachers and 78 students from 8 different schools.In the last few years, we have needed to explore and understand the power of nature more. We have volunteered to be aware of and protect the opportunities that the world we live in offers us. Who are we? All of us partners of the eTwinning project “STEAM for Green Nature”.

We crossed paths with some of them in the “Digital Science” eTwinning project last year and this year we continue to work on the project with new partners. We made our project application in January and started STEM learning scenario activities in February. Our projeject will finish on April 30. The basis of our work is a STEAM learning scenario. We apply the steps of the learning scenario in our schools.

My learning scenario is below link.

Aim of the project

Our aim with our project is to raise awareness for a sustainable climate, first among our students and then in a larger audience. To explain the importance of our students adapting less harmful activities to climate change into their future lifestyles. When we started the project preparations to popularize STEAM studies, we determined studies suitable for the participation of our colleagues from different branches. Because, the “Global Climate Crisis” is a problem for all of us. We worked with teachers from Science, Social Studies, and English branches. In addition, our group teachers, and visual and technical design teachers in our schools also supported us.

In the implementation of the learning scenario, we carried out our work both face-to-face and remotely. Mixed country teamwork and collaborative work were also included in our work.


There are many activities in our scenario, which we integrated with our course topics. After the pre-test we applied, our students prepared posters and logos. We constantly updated our activities according to the decisions we made with our partners and students at our monthly meetings.Our partners attended seminars for the safe internet day, and each school organized seminars for its own students.

Expert Support

As expert support, we have planned an online seminar with the responsible of the Turkish Anti-Erosion and Afforestation (TEMA) Foundation. ITU Environmental Engineering Environment Club made an online presentation on “Tears of Water” to our students on World Water Day.


outdoor activity

We did an outdoor activity. With the Plantnet phone application, our students became aware of the diversity of plants in our school’s garden.

On April 15-16, Turkey II. We attended the Scientix workshop and introduced our project. Also, we shared our project in the İzmir ETwinning İzmir News bulletin and in the book “Turkey Scientix Ambassadors Project Studies”.


Learning Outcomes

Students learned the causes and consequences of climate change. So, they discovered what they could do to reduce global warming. They became aware of the vegetation around them and realized the importance of biodiversity. On the other hand, their digital competencies have improved,

NBS to Prevent Carbon Emission


How will the new generations growing up in environmental problems such as carbon emission and global warming deal with this problem?

In this Learning Senario it is aimed to find a solution to global warming and to increase awareness.
First, the students answer the pre-test questions. Then, by watching videos on the subject, discussion is started, brainstormed and they share their thoughts in the pedlette. They watch scientific resources, global warming studies and videos on climate change. After that, Reviews IPCC 2020 and IPBES 2019 report. To learn about citizens’ views on environmental problems, students go to a park and try to identify problems by meeting with the citizens there.But, the park was not visited (due to the epidemic)

Using Web 2.0 tools, they make posters, videos, and puzzles about the environment they want to live in. In the first activity, it calculates the carbon emission per person with the carbon footprint calculator. Accordingly, they calculate the number of trees we need to plant per person. Then they try to find nature-based solutions to prevent carbon emissions. In second activity, “What can we do to reduce plastic waste? “They look for the answer to the question. They are doing a “Let’s make bioplastic” activity. Finally, they answer the final test questions.

Brainstorming and discussion

Environmental problems are increasing day by day. Think of yourself as an environmental engineer. İf you were, how would you solve this problem? Discuss the problem.

What are the causes of environmental problems? Do you have any solution to avoid Carbon Emissions? Can we find solutions to reduce the effects of environmental pollution? Firstly, students discuss the questions. Secondly, they share on pedlet the problems they face in their environment. After that,they comment on each other on the topics they share in Padlet. Pupils design posters reflecting environmental problems with Web 2.0 tools. They, prepare a puzzle game from the posters they have prepared.


Students go to a nearby park and make interviews. Questions should be prepared in advance and answers recorded or noted. For example, what do you think about environmental problems like carbon emission and global warming? But we did not do this activity due to the pandemic. A word cloud on environmental issues was created with Wordart.

Students are asked what kind of world they want to live in. They make a video about “my dream world” using Web 2.0 tools. Thus, the students shared their beautiful dreams with each other.

My dream world

Activity 1:


What is global warming and, greenhouse effect and climate change? What is recycling?

Our world is warming up… According to measurements made in recent years, greenhouse gases in the Earth’s atmosphere cause more of the heat they lose. As a result, glaciers are melting in our increasingly warmer world. Snowfall is decreasing. In short, the climate of our world is changing. In other words, carbon dioxide gases accumulating in the atmosphere cause global warming and climate changes.Therefore, if we recognize the factors that affect global warming and act consciously, we can reduce our carbon footprint.

The amount of carbon dioxide released into the atmosphere can be measured by the carbon footprint, meaning the damage individuals and companies leave to the world.Following the explanations, students calculate their carbon footprint using the Carbon Footprint Calculator, If desired, a tree-planting campaign can start.

Last, students create avatars with pixton and make them talk to chatterpix to design slogans on environmental problems such as global warming.


The results were evaluated and recorded. According to the survey results, the average carbon footprint per person is shown in the graphic below.

survey results and footprint per person

According to the results of our school, the average carbon footprint is 6.3 tons. As long as a tree lives, it breathes 0.73 tons of carbon dioxide. As a result of, the number of trees to be planted per person in our school is 9. At the end of the activity if possible, a tree planting campaign can be started.

They are asked to produce solutions on this issue. After that, answers to the question of how to prevent carbon emission and global warming were noted on pedlet.. Nature Based Solutions To Prevent Carbon Emissions:

answers to the question of how to prevent global warming were noted.

Activity 2:

İntroduction: What is the role of plastics in carbon emission and global warming?

We use plastic materials in many areas of our daily life. Because, plastics are easy to shape. It also provides heat and electrical insulation. Some of the plastics are recycled. However, plastic waste that cannot be recycled is becoming a huge threat to our world. If you were a biochemist, what solution would you find? Could using bioplastics be a solution? Students will learn with information about the subject using various resource.

Let’s make bioplastics

First, the materials required to make Bioplastics are informed to students. Than, they make bioplastics.


1 tablespoon starch, 4 tablespoons water, 1 teaspoon glycerin, 1 teaspoon vinegar, Pot or coffee pot, Food Dye, Aluminum foil and Heater


Firstly, put the water and starch in the pot and mix. Secondly, add vinegar and glycerin on it. Add food coloring to the mixture that we prepare optionally. Than,Heat, stirring, to a gel-like consistency and spread it on aluminum foil and let it dry for two to three days. Finally, Keep it in the mold for two or three days.

The Shelter STEM

This Shelter STEM project is designed for children between the ages of 7 and 10. This activity has been designed within the scope of Step by Step STEM eTwinning project activities.  Students learn the impact of climate change and global warming on our lives, towns, cities. They learn to measure temperature of some objects and the air on different places and they create a model of a shelter.


Firstly the children (7 years old) discuss the story about elves (the class is called elves):

Our friends Elves, they live in the forests. They like cool and fresh air. They are going to visit our town and there are not many shelters to have cool air. So they will go and measure the surface temperature on different places. (worksheet1) . Then they compare they results.


Secondly, the children watch YouTube video about city warming. Then they discuss what they saw and they speak about their town – how do they feel about it.

MY WATER OF LIFE / “The Effects of Drought Increase on Plant Diversity and Forests”


Global warming and climate change threaten even water-rich countries by dragging the world into an uncertain future. Therefore, water literacy is extremely important for the conservation and conservation of water, which is a vital resource for life. With this project, students will learn by observing the behavior of water in their daily lives, by experiencing how it gets polluted and how it should be protected. The widespread use of water literacy among students will make an important contribution to the protection of the ecological system.


With this project, it was aimed to make students water literate by creating water awareness against the increasing water pollution in the world. In addition, it was aimed to use water, which is one of the most important resources in the world and used irresponsibly, among our students, parents and teachers in a more careful and economical way. In addition, with web 2.0 tools, it was aimed to improve students’ foreign language skills and to use technologies such as computers and mobile phones safely.
