Body Temperature

Have you ever felt really warm after running around
or really cold after standing outside in chilly
weather? Today, we’re going to explore why that
happens. Our bodies are amazing at keeping a
steady temperature, no matter if we’re moving
around a lot or the weather changes. Let’s find out
how our body does this and why it’s so important!

• Install Vizeey™ on your
  Smart device.

Topics: Temperature Regulation,
Circulatory System

The human body has a remarkable ability to maintain
a stable internal temperature, a process known as
thermoregulation. The average core body temperature
for humans is around 37°C (98.6°F), with a normal range
typically between 36.5°C and 37.5°C (97.7°F to 99.5°F).
This stable temperature is important because the
body’s organs, like heart and brain, can only work
properly within a narrow temperature range. If your body
gets too hot or too cold, it can cause problems.

During exercise, muscle activity generates heat, causing
the body's temperature to rise. To prevent overheating,
the circulatory system increases blood flow to the skin,
allowing heat to dissipate into the environment.
Sweating also helps cool the body. As the sweat
evaporates, it cools the body down.

When it’s too cold, the body conserves heat by reducing
blood flow to the skin, shivering to generate warmth,
and creating "goosebumps" to trap heat. This balance
helps keep the internal temperature steady at around
37°C (98.6°F), so the body can function properly.

We can help our bodies keep a stable temperature by
adopting healthy habits like eating a balanced diet,
which provides the energy needed for heat production;
drinking enough water to support bodily functions such
as sweating and blood flow; dressing appropriately for
the weather; and planning activities based on the
temperature and humidity.

Learning Objectives

In this investigation you will master the following knowledge and skills:

• Visualize, collect and analyze data

• Measure and record temperature in C or F

• The body’s ability to maintain a stable internal temperature is essential for proper
  function and health.

• The circulatory system helps regulate temperature by adjusting blood flow to the skin’s
  surface to release or retain heat.

Temperature regulation: also called thermoregulation, is the process your body uses to
keep its internal temperature steady. Even when it’s really hot or cold outside, or when
you’re being active, your body works hard to stay at about 37°C (98.6°F).

Circulatory system: the system in your body responsible for transporting blood, oxygen,
nutrients, and waste materials. It acts like a delivery network, ensuring that every part of
your body gets what it needs to stay alive and function properly. Parts of the Circulatory
System are heart, blood vessels and blood.

In this lab, you will measure skin temperature before and after
exercise to understand how your body responds to physical
activity. You’ll learn how the circulatory system works to regulate
body temperature and why maintaining a healthy temperature
range is essential for preventing disease and supporting overall
health.

Your Body Loses Heat in Water Faster Than Air: Water transfers heat 25 times faster than
air, which is why you feel colder swimming in cool water than standing in the same
temperature air!

Your Body as a Thermometer: Ever touched a surface and instantly known if it was hot or
cold? Your skin senses temperature, but it can be tricked—holding one hand in warm water
and the other in cold, then putting both in lukewarm water makes the temperatures feel
reversed!

Temp Probe

In order to work with the experiment you need to launch the Vizeey application and click on
+ in the upper right corner.

Then select “Add experiment from QR code” and scan the QR code prepared for this
experiment. Your experiment will appear in the list.

Press this button to start the
experiment.

When you start the experiment you will be immediately
offered to connect to your databot. Make sure that databot
is enabled.

Don’t forget to check that the temperature probe is
connected to the Temp 1 port.

During the experiment, you need to record the temperature values every 30 seconds.

Press the "Fix Temp Value" button every 30 seconds to capture the next values for your
data table.

Once you have captured the values, write them down in the table to avoid losing any
information and prepare to capture the values at the next 30 second mark. Be fast and
accurate!

• Here you will see a graph of temperature
  change over time.

• The temperature value you can
  fix at the current moment by
  pressing the button.

• General information
  about the experiment

• Stopwatch from the start of the
  program (If you want to reset the timer
  to 0 you need to restart the experiment).

Part 4: Data Analysis

1. Graphing Your Data:

Create a line graph to compare skin temperature before and after exercise.

• • X-axis: Time (seconds)

  • Y-axis: Temperature (°C)

  • Use different colors or labels for "During Exercise" and "After Exercise" conditions.

2. Observing Patterns:

Examine how your skin temperature changed from exercise to post-exercise
measurements. Consider what this pattern suggests about how your body responds to
physical activity.

Part 5: Concept Questions

Part 6: Reflection

1. What did you learn about how your body’s temperature changes during physical
   activity?

2. Why is it important to stay hydrated and rest after exercise to help your body maintain
a healthy temperature?

3. How does keeping a stable temperature help prevent disease and promote healthy
body function?

Part 7: Healthy Habit Tips

To maintain a healthy body temperature, here are some habits that support temperature
regulation and overall health:

• Stay Hydrated: Drinking water helps your body cool down during exercise and
  maintains fluid balance.

• Rest After Exercise: Allow your body to recover, which helps it return to a normal
  temperature range.

• Wear Weather-Appropriate Clothing: Dressing appropriately for the weather helps
  prevent overheating or excessive cooling.

• Eat a Balanced Diet: Provides your body with the energy needed to support temperature
  regulation processes.

Understanding Body Temperature Regulation:

1. How does the circulatory system help your body regulate temperature during exercise?

2. What are some ways the body tries to cool down when it gets too warm?
