We are so happy that you are joining us for the STEM Investigation Camp! Welcome to Day 3. We hope that you enjoyed Day 2 of the camp and are ready to have some cool new experiences with STEM and gain some additional skills to help you solve the overarching mystery presented in the introduction for this camp!

Based on the DNA samples collected at the scene of the crash, scientists estimate the time of death to have been approximately 6 minutes after take off.
Day 3: Life Science
Day 3: Life Science
Life Science is a branch of science (such as biology, medicine, and sometimes anthropology or sociology) that deals with living organisms and life processes.
Jobs in Life Sciences: If you would like to know more about careers in Life Sciences, here’s a link to information on what it takes to get a career in Life Sciences, as well as some of the jobs that they do:

STEM@HOME Challenge
STEM@HOME Challenge
The STEM@HOME Challenges are hands-on STEM activities and challenges, designed to utilize materials many families may have at home or can easily source at the grocery store.
Check Your Pulse:
Check Your Pulse:
In this cool experiment you will make a device that will allow you to actually see your heartbeat and time it!
Materials Needed:
Materials Needed:
Pencil with eraser
Bubble gum or clay
Straw or tooth pick
Watch or timer
Instructions:
Instructions:
If you have playdough or clay at home, take a small lump of clay and knead it so that it is soft enough to shape. If you don’t have play doh or clay, take a piece of bubble gum included in your STEM Toolkit and chew it until the gum is soft enough to shape.
Turn your arm over so that your wrist is facing upward and rest it on a table or other support surface.
Shape the playdough, clay or chewing gum into a small disc roughly the size of a quarter.
Place the lump of playdough, clay or chewing gum on your wrist just below your hand. Make sure that the gum or clay is well attached to your wrist.
Insert the straw from your toolkit or a toothpick from your home into the clay or gum with the straw or toothpick standing vertically out of the clay/gum.
If you are very still and watch the tip of the straw/toothpick you will see the tip of it twitch with every beat of your heart. You are actually watching your heartbeat!
Time your heartbeat for 10 seconds. Record your observation in the table below. Multiply the 10 second rate by 6 to get the number of times your heart beats in 60 seconds or one minute. You now have your heart rate in beats per minute. Record this rate on the resting heart rate line.
Now do moderate exercise like lifting a can of food 10 times, walking around the room 3 times or doing 5 sit-ups. Repeat steps 2-7, but this time you will record the rate on the moderate exercise line.
Now do a little more energetic exercise like lifting heavy books with both hands 20 times, 10 knee bends, walk around the block, go up and down the stairs three times, or do 20 sit-ups. Repeat steps 2-7, but this time you will record the rate on the strenuous exercise line.
