Challenge 1
To immobilise the thumb:
- 2 cloth gloves
- 2 rolls of masking tape
- 10 lollipop sticks
- 5 jumbo lollipop sticks
- 10 rubber bands of different lengths
- 2 Velcro strips - male and female (length about 20 cm) for attaching
- 1 pair of scissors
- 2 pieces of cardboard or another hard surface (approx. 10 X 5 cm)
- 2 narrow and short cardboard tubes (size of thumb - diameter about 2 cm and length about 5 cm)
For the challenge:
- 2 pencils/pens
- 2 connect-the-dot picture pages, e.g.:
Challenge 2
To immobilise the elbow:
- 1 tube (about 9-10 cm wide and 25 cm long), cut lengthwise (to insert the hand into it and prevent movement of the elbow)
- 1 wooden board (approx. 7 X 25 cm)
- 4 wide Velcro straps (approx. 30 cm long) (to attach the board to the arm).
For the challenge:
- 2 spoons
- 2 thick, insulated, flexible power cords (each about 30 cm long)
- 2 rolls of masking tape
- 10 rubber bands of different lengths
- 1 spool of wire / string
- 10 strips of Velcro - male and female (each about 3 cm long)
- 10 large paper clips
- 10 lollipop sticks
- 1 pair of scissors
Challenge 3
To immobilise the fingers:
- 2 cloth gloves
- 2 thin, stiff surfaces like cardboard or foam board (10 X 10 cm)
- 4 thin strips of Velcro (each about 25 cm long) (to attach the board to the hand)
For the challenge:
- 2 markers
- 1 pair of scissors
- 2 pieces of paper
- 2 thick, insulated, flexible power cords (each about 30 cm long)
- 2 rolls of masking tape
- 10 rubber bands
- 1 spool of wire / string
- 10 pieces of Velcro, 2 cm
- 10 paper clips
- 10 popsicle sticks
Challenge 4
To immobilise the fingers:
- 2 cloth gloves
- 2 thin, stiff surfaces such as cardboard or foam board (10 X 10 cm)
- 4 thin strips of Velcro (each about 25 cm long) to attach the board to the hand
For the challenge:
- 1 pair of scissors
- 2 hard cups without handles
- 2 thick, insulated, flexible power cords (each about 30 cm long)
- 2 rolls of masking tape
- 10 rubber bands of different lengths

Preparation
Organization and purchase of equipment and materials.
Goals, messages & concepts
Specific goals
- Understand the importance of joints while attempting to complete daily activities with immovable joints
- Use engineering to solve challenges
Specific messages
- Keeping the joints rigid simulates the decreased range of motion that occurs with joint impairment
- Impairment of joints makes it difficult to perform daily tasks
- Working in a team makes it possible to reach a variety of creative solutions

Course of activity
step 1
First, students will recap the purpose of joints in the body, and consider the impact of having limited movement in your joints. They will try to accomplish simple tasks with some of their joints ‘fixed’ in place.
step 2
- The activity illustrates the importance of the joints, encourages empathy for people with disabilities, and provides a new and different type of educational experience. It is based on an activity developed by Forth (formerly FixEd).
- Students will work in pairs/threes in stations; each of the four stations will have a defined task, an array of possible materials and equipment that can be used for accomplishing the task, and pencil and paper.
- Challenge 1: Connect the dots with an immobilised thumb
- Challenge 2: Use a spoon with an immobilised elbow
- Challenge 3: Use scissors or a pen with a hand limitation
- Challenge 4: Drink from a cup with a hand limitation
For challenges 2-4, design and build an accessory that will help accomplish the task. Student instruction sheet for this activity are in the resources (title: The fixed joint challenges) which includes tasks and photos. Photos for ideas and inspiration can be found here.
step 3
Presenting their inventions (give 5 minutes to prepare the presentation, 1 minute for each presentation). Students can name their invention, point out pros and cons, and discuss how it could be improved. Possible extension activity – show the following video, produced by Forth organisation, about design students who help solve a problem of a person with impaired mobility: https://www.youtube.com/watch?v=L4jGOZMOJ1c
