- Using the stethoscope place the end flat, near your heart
(located on the left side of your sternum, the hard bone in the center of your ribs)
- Have your partner listen to your heartbeat. Record your heartbeat for
30 seconds on your student sheet.
- Jog in place for 30 seconds. Repeat the steps above and record your
heartbeat on your student sheet.
Activity / Time / HeartbeatsAt Rest / 30 seconds
After Running / 30 seconds
QUESTIONS:
- What happened to your heartbeat after you exercised?
- Why do you think that your heartbeat changed?
Station 2: Measuring Body Temperature / Integumentary System
PART ONE:
- Use the SPARK to measure temperature. Make sure the temperature probe is plugged into
the SPARK (it’s the white wire with a bulb on the end).Press the button
on the left side of the screen that says TEMPERATURE.
- When TEMPERATURE is highlighted. Press the SHOW button at the bottom of the screen.
- Place the end of the white wire (the bulb) in the bend of your elbow and
bend your arm up so that you are flexing your muscle.
- Press the start button on the graph (green arrow) and observe the temperature for 30 seconds.
- When 30 seconds have elapsed, press the orange arrow button at the bottom to stop
graphing the temperature. Record your observations.
PART TWO:
- RUN in place as fast as you can for 45 seconds. Quickly place the bulb in the bend your elbow
and repeat the steps 4, 5, and 6 above to create a second graph. Record your observations.
Activity / Describe the temperatureAt rest
After Running
- When finished with observations and data, click the “Home” button in the top left corner.
Do not save your data.
QUESTIONS:
- Compare the graphs before running and after running. What happened
to the temperature of your body?
2. What predictions can you make about the change in temperature?
3. What body systems do you think control your temperature?
Station 3: Measuring Bones / Skeletal SystemHumans and gorillas are both primates. We both have a
major arm bone called a humerus and a major leg bone
called a femur. The STRUCTURE of each of these bones is
different, and their FUNCTION is different too!
- Measure the length of your humerus (the arm bone
from the shoulder to the elbow).
- Measure your femur (the leg bone below your hip to
your knee). Record your observations
3. Use a ruler and the scale to measure the length of the
gorillahumerus and femur (on back of this sheet).
Bone / Length (cm)Human Humerus
Human Femur
Bone / Length (cm)
GorillaHumerus
Gorilla Femur
Gorillas are knuckle walkers.
Which is bigger, a gorilla leg
or arm bone?
Station 4: Measuring Lung Capacity / Respiratory System- Select two group members. Each group member
should breathe in as deeply as they can and then
exhale to blow up the balloon with one breath.
Observe what happens to your chest and stomach
as you inhale and exhale.
- Repeat two or three times.
QUESTIONS:
- Which partner had a greater lung capacity? How do you know?
- What happened to your chest and stomach as you inhaled and exhaled?
Station 5: Observing a Stimulation Response / Nervous System
1. Close your eyes tightly for 30 seconds.
2. Open your eyes while looking at the mirror.
3. Record your observations on your student sheet.
4. Now experiment with the flashlight (you may use the flashlight on your phone). Observe how your pupil responds to the light stimulus.
1. A stimulus is something that causes a reaction. What was the stimulus in this station?
2. A reaction is what occurs because of the stimulus. What was the reaction in this station?
3. Why do you think our pupils do this?
4. Cameras are designed like a pupil. Can you think of how a camera might work in the same way?
Station 6: Drink It Up… / Digestive SystemProcedure:
Listen to your partner take a drink of water using a stethoscope.
Describe what you observe on the lab sheet.
- What path is the water taking when it is swallowed? Where is it traveling the human body?Use the above diagram to help you answer this question!
2. Do you think food would take the same path in the digestive system? Why or why not?
Station 7: Magic Arms / Muscular System1. Stand up straight with your arms down at your sides. Try to raise your arms up and out as your partner pushes down on your forearms to keep your arms at your side.
2. Hold this position for at least a minute. After a minute have your partner let go of your forearms. Observe what happens to your arms after they let go.
1. What do you think is happening?
2. Where does the muscle get the energy that it needs to perform this job?Think about where we get energy from!
Station 8: Name That System! / BODY SYSTEMS****************Use this week’s homework as a resource for this station************************
1. I am the body system that is responsible for transporting oxygen and nutrients to all parts of the body. I am also in charge of transporting waste away from cells.
2. I am the body system that controls the body. I respond to internal and external stimuli and cause responses that help the body.
3. I am the body system that obtains oxygen from the air for the body to use. I also get rid of carbon dioxide that is no longer needed by the cells of the body.
4. I am the body system that provides support for the body. I am also in charge of making blood cells for the body.
5. I am the body system that provides protection for the body. I perform a similar job to the cell membrane of a cell. I also help control the temperature of the body.
6. I am the body system that takes in and breaks down nutrients for the body.
7. I am the body system that is responsible for producing offspring.
