Step1 Noticing and questioning when various things are heated or cooled
What happens when things are heated or cooled?
Demonstration 1: Placing a plastic bottle in hot or icy water
Demonstration 2: Putting a plastic bottle filled with water into hot or icy water
Demonstration 3: Putting an empty can in hot water or ice water
The students will learn about temperature and volume through the demonstrations.
Write down what you learn from the demonstrations on cards.
Summarize the questions raised through the three experiments.
Set a theme based on the questions that emerged.
Step2 Experiment to confirm and discuss the relationship between temperature and volume of air, water, and metals
Let's investigate the relationship between temperature and volume of air, water, and metal.
Experiment 1: What happens to the volume of air when the temperature of air changes?
Experiment 2: What happens to the volume of water when the temperature of water changes?
Experiment 3: What happens to the volume of metal when the temperature of metal changes?
Students will conduct three experiments in the pattern of "prediction → experiment → result → summary" and summarize the results on a candy chart.
Compare the results of the three experiments and summarize what can be learned from the three experiments.
Step3 Let's devise a way to make it easy for even the weakest person to open the metal lid!
Let's try to make it easier to open a lid that won't open.
Question: What is the easiest way to open a metal lid?
1) Think about the reason why it does not open.
2) Think about what should be done to open it.
3) Think of a way to open the lid based on what you have learned so far.
4) Consider the experimental method
1) Think about what should be done in order to open.
2) Choose one or two experimental methods in the group and summarize the experimental method
3) Conduct the experiment and summarize the results and findings
In order to use the knowledge gained in this unit in their daily lives, students will be given assignments using the content they have learned so far.
After considering the reason why the lid of a metal box does not open, think about how to open the lid based on the characteristics of air, water, and metal boxes. At this point, the students are encouraged to think of an experimental method that has a basis in the previous experiments.
After thinking about how to open the door individually, the group will discuss and decide on the experimental method.
After the experiment, summarize the results and findings.
Step4 Thinking about the "life innovations" in the textbooks
Think about something that uses the temperature and volume of things.
Q1: What are the joints in a bridge?
Q2: What was the ingenuity when the Tokyo Sky Tree was built?
Summary of the unit
Think about the things in our daily life that use "temperature and volume".
→Be able to explain in your own words.
Write a summary in your own words as a summary of the unit and share it with the class.
Also, review the class.
Comment from the teacher
The lesson plan was designed to connect the content of the study to daily life by asking questions that will be useful in the future, and by placing the questions at the top of the thinking process, the children will be able to utilize what they have learned and further deepen their thinking.
