Hands On Science Cool Body Tech
Exploring Amazing Body Technology Grade 5 Science Adventure Get Ready to Move and Learn!
Warm-Up Challenge!
Look at your hands right now! How many different ways can you move your fingers? Try making a fist, then spread them wide! What helps your fingers bend and move?
Hand Movement Challenge
Stand up and follow along! Make a fist - hold for 3 seconds Spread fingers wide - wiggle them! Point with one finger Give a thumbs up! Now touch each fingertip to your thumb
Meet Your Amazing Tendons!
Tendons are like strong ropes inside your body They connect muscles to bones When muscles pull on tendons, your fingers move! Feel the back of your hand while moving fingers
Motion: How We Move
Motion means movement from one place to another Your brain sends signals to muscles Muscles pull tendons to create motion Practice: slowly bend and straighten your fingers
Grip: Your Super Power!
Grip is how strongly you can hold things Different grips for different jobs Try holding a pencil vs. a basketball Your thumb is the grip champion!
Flexibility Test!
Flexibility means how much you can bend and stretch Try these moves with your hands: Bend wrist up and down Rotate wrist in circles Touch thumb to pinky finger Stretch fingers as wide as possible!
Sensors: Your Body's Detectives
Sensors in your skin detect touch, heat, and pressure Close your eyes and touch different textures Your fingertips have the most sensors! Sensors send messages to your brain
Prosthetic: Amazing Replacement Parts
A prosthetic replaces a missing body part Modern prosthetics can move like real hands! Some use sensors to detect muscle signals Technology helps people do amazing things!
Science is Amazing!
Your hands are incredible machines with tendons for motion, sensors for feeling, flexibility for movement, and grip for holding. Scientists and engineers study how hands work to create amazing prosthetic technology that helps people do wonderful things!
