By making an ecodesigned dinosaur, students will be able to recognize building materials in everyday trash, use those materials to create artifacts for school and for fun and apply concepts of reduce, reuse and recycling.
Step 1: Materials
- 1 case for orthodontic retainer (for the head. You can replace it with a computer mouse, but it will be more tricky to build the mouth)
- Plastic caps and cases from shaving foam, liquid detergents, beverage and other plastic stuff (look at the picture)
- Screws, nuts and rings
- 2 plastic circles (for the eyes. I use two from alcoholometer mouthpieces)
- Red rubber or EVA foam (for the tongue)
- For the arms, I use pieces from a damaged Transformer (the legs of an Animated Bumblebee)
Dremel Rotary Tool
And don't forget:
1. If you don't have it, replace it!
2. Use protective equipment (dust mask and goggles)
3. Beware of drilled and soldered hot surfaces
4. Work in a good ventilated area.
5. Always have junk in stock
Step 2: Drilling Joint Holes
Drill holes in the upper part of the toothbrush cases (for the legs articulation)
Step 3: Head, Neck and Body
In the end, screw a ring and a nut.
Step 4: Legs
Using screws and bolts, attach each leg to each side.
Step 5: Tail
Put the beverage cap and fix it with screws. Now, you have the tail.
Step 6: Arms
Cut the joystick piece in half, making two talons, and attach them in each arm.
Attach one arm in each side of the dinosaurs neck.
Step 7: Face
Glue the red rubber piece (or red EVA foam) to the mouth, for making the tongue.
And now, YOU HAVE YOUR ECODESIGNED DINOSAUR TOY!
