The experiment was done in a special room where scientists could control the temperature, humidity, and oxygen levels. The person taking part in the experiment was connected to monitors to keep track of their body temperature, heart rate, and blood pressure. As the temperature dropped from a comfortable 21 degrees Celsius to 10 degrees Celsius, the body started to react. Sweating stopped, hairs stood up to keep warm, and blood vessels in the hands got smaller to keep the important organs warm.
The effects of cold weather on the body were also shown by the person's muscles shaking and changes in blood flow to the brain. The brain didn't get as much oxygen and glucose, which made it harder to think clearly. But the body's main goal of keeping warm stayed the same, even though it had to work harder. The heart had to pump harder to keep warm blood flowing, and blood pressure went up, which can be dangerous for the heart.
It's really important to know that cold weather can be dangerous. In fact, it's more dangerous than hot weather. Cold weather also makes it easier for viruses, like the flu, to spread, and it increases the risk of getting infections like pneumonia. When we're indoors with the windows closed and no fresh air, it's easier for viruses to spread. Cold air also weakens our immune system in our nose, which makes it easier for viruses to grow.
To protect ourselves from the effects of cold weather, we should wear warm clothes, like woolly clothes. It's more important to wear gloves and warm socks than a hat, but a hat can also help. Eating foods with lots of carbohydrates can help keep us warm, and staying active instead of sitting still can also help. Overall, it's really important to know how cold weather affects our bodies and take the right steps to stay healthy.

Group or Classroom Activities
Warm-up Activities:
– News Summary
Instructions: Divide the class into pairs. Each pair will read the article together and then summarize the main points in their own words. After a few minutes, ask each pair to share their summary with the class and discuss any differences or similarities between the summaries.
– Sketch It
Instructions: Give each student a piece of paper and a pen or pencil. Instruct them to sketch a visual representation of the effects of cold weather on the body based on the information in the article. After a few minutes, have the students share their sketches with a partner and explain their drawings. Then, invite a few students to share their sketches with the whole class.
– Vocabulary Pictionary
Instructions: Write a list of vocabulary words from the article on the board (e.g. temperature, humidity, glucose, immune system). Divide the class into two teams. Call out one vocabulary word at a time and have one student from each team come to the board to draw a quick sketch to represent the word. The rest of the team must guess the word based on the sketch. The team that guesses correctly earns a point. Continue until all the vocabulary words have been used or until time runs out.
– Pros and Cons
Instructions: Divide the class into two groups. One group will discuss the pros of cold weather, while the other group will discuss the cons. Give the groups a few minutes to brainstorm their ideas. Then, have a representative from each group present their arguments to the class. Encourage the class to ask questions or challenge the arguments presented. After both groups have presented, facilitate a class discussion on the topic, allowing students to share their own opinions and perspectives.
– Future Predictions
Instructions: In pairs or small groups, have the students discuss and make predictions about the future effects of cold weather on our bodies. They should consider potential advancements in technology, changes in climate, and other factors that may influence how cold weather affects our health. After the discussion, ask each group to share their predictions with the class. Encourage the class to ask follow-up questions or challenge the predictions presented.
π€ Comprehension Questions:
Living in a cold home can seriously affect our health. Even at a temperature of 10 degrees Celsius, which is the average temperature in homes without heating, our heart, lungs, and brain can be affected.
The experiment was conducted at a temperature of 10 degrees Celsius.
Scientists were able to control the temperature, humidity, and oxygen levels in the special room.
As the temperature dropped, the body went through various changes. Sweating stopped, hairs stood up to keep warm, blood vessels in the hands got smaller to keep the important organs warm, and the person's muscles started shaking.
The person's muscles started shaking in response to the cold weather.
In the cold, the brain didn't receive as much oxygen and glucose, which made it harder to think clearly.
Cold weather is more dangerous than hot weather because it can make it easier for viruses, like the flu, to spread. It also weakens our immune system, making it easier for viruses to grow. Additionally, cold weather increases the risk of getting infections like pneumonia.
Cold weather makes it easier for viruses to spread because when we're indoors with the windows closed and no fresh air, it's easier for viruses to circulate. Cold air also weakens our immune system in our nose, making it easier for viruses to grow.
