Body Movement Inspired Design
Starter Activity • You have 2 mins to complete the worksheet. • Cut up the bottom in the small parts and place them where you think they go on the skeletal frame.
What Are we Learning Today
What I am Looking For
• Identify some of the different types of joints, levers and muscles • Identify where they are found in the body • Identify some products that generate movement or the ability to be moved. • Understand how some products generate movement or the ability to be moved. • Identify where products have copied or simulated the same movements in the body. • How to generate movement using ICT – CAD; Seri Drawplus.
• All students to complete start activity • All students to complete mix and match activity • Most students to complete Product Poster • Some students to complete their body movement inspired design product stop frame animation on Serif Drawplus.
Re-visiting the starter activity
Who thinks they have placed the parts in the right place? Have a go and place them on the large scale skeletal frame.
Joints • A ball and socket joint: found in the shoulder and hip. This joint allows the greatest range of movement. • A hinge joint: found at the elbow and knee. The range of movement is limited to one plane just like a door hinge. • A pivot joint: found in the neck. Part of the bone fits into another ring of bone as in take atlas and axis, allowing rotation of the head.
Levers •
First order levers: The pivot is between the effort and the load. Both effort and load are in the same direction. – An example ; where the head pivots on the atlas. The load is the weight of the head going down. The effort is the muscles at the back of the neck pulling down.
•
Second order levers: The pivot is at one end of the lever. The load is in the middle of the lever. The effort is at the opposite end of the lever to the pivot with the direction of effort opposite the load. – An example; stepping up onto your toes. The pivot is at the toes. The load is that of the body going through the middle of the foot and the effort is in the calf muscles pulling the body upon to the toes. This is the most effective lever as a relatively small force can move a large weight.
•
Third order levers: The pivot and load are at opposite ends of the lever but the effort is off-centre towards the fulcrum. – An example; biceps curl. The load is in the hand, the pivot is at the elbow and the biceps make the effort.
Muscles • Cardiac muscle or Heart Muscle is specialised muscle that contracts constantly and automatically. Some factors can affect the speed of the contractions such as exercise and the release of hormones such as adrenaline. • Skeletal muscle are the ones that can easily be seen as a shape under the skin. Unlike smooth muscle or cardiac muscle, we can control skeletal muscles and because of this it is sometimes known as voluntary muscle.
Activities
• Complete the mix and match activity worksheet. Use the handling collection to help you understand what joints, levers and muscles are used. • In your group on your table, complete the product poster. Identify what joints, levers and muscles are being used. Don’t worry of you make a mistake it wipe-able. Make sure everyone in your group inputs.
Now I want you to go make animation of a product from the poster. Use Serif Drawplus – stopframe animation to show how the specific joint, lever or muscles enables it to move.
