In this lesson, we will be learning about the inner workings of the skeletal and muscular systems by creating a paper model of a hand. The fingers will be bendable, and the movements will demonstrate how the bones and ligaments in our fingers move. The recommended age group for this project is 7-10, though all ages are welcome.
MATERIALS NEEDED:
- paper (preferably construction paper)
- a pencil - scissors - 4 to 5 plastic drinking straws (preferably 2 different colors- 2 of each) - tape - at least 30 inches of string - ruler HOW TO
Step 1, trace your hand onto the paper. *a larger size is better, so trace an adult hand, or draw it bigger if possible*
Step 2, cut the straws into 14 pieces that are around 1/2 inch long. You can also measure this by measuring the size of the finger, and dividing that into thirds. You can use this length in place of the 1/2 inch to get a more exact fit. Step 3, tape the straw pieces in a row on each finger. Step 4, cut and measure straw pieces to go from each finger to the base of the palm. Step 5, tape down the straw pieces going from each finger to the palm. All of your straw pieces should now be taped down. Step 6, cut 5 lengths of string long enough to run down from the tips of the fingers to slightly past the wrist. Step 7, tape a string to the backside of each finger tip. Pull the string to the front of the hand, and string it through the plastic straws on that finger, then through the straw running to the wrist. Tip: place the finger off the edge of a table to make it easier to string through. Step 8, now you can pull the strings to make the fingers bend open and closed! THE LESSON
As we are making this skeletal system diagram in our free live session, we will be describing the basic topics of bones, ligaments, tendons. This includes the functions of the skeletal system and muscular system. The kids would learn what each of these topics are, the basic ideas of each, and how it is shown in their hand and in their diagram. This project uses critical thinking skills and since it is a hands-on activity, kids are more likely to remember what they have learned and are able to make connections with information they already know, and what they will learn in the future. You can find our explanations in the presentation below! And, you can click on the video file below to watch the finished hand model in action, it can contract just like a real hand!
