Innovations in Technology - Challenge 1
[ Home | Categories | Timetable | Challenge 2 | Judging the Innovations]

The challenge for Crafty Design is to create a craft that resembles some of the Macro invertebrates that live in and around the water. Macro means that we can see it with our eyes. Invertebrates are small animals and are a collective term used for all animals without a backbone which include spiders, crustaceans, worms, insects and molluscs. There will be a special prize for those who demonstrate they have met the objective.

One of the Macro invertebrates we at Waterwatch are intrigued with is the Mayflies; the mayfly nymphs can be identified by their three tails. They are found throughout Australia inhabiting streams, rivers, wetlands and pools, under bark, logs and rocks. The Mayfly nymphs all graze on algae or plants or consume detritus. Secondary students are encouraged to create other ways for craft to travel, e.g. craft must still have contact with water; under water.

Using construction materials such as TEKO, LASY and LEGO in conjunction with scrap material, create a stable craft (in keeping with the above theme) which will run under its own power, along a channel of 9.4 metres x 81.5 cm, carrying a full soft drink can. Please note that the water depth of the channel is approximately 12 cm. Craft must complete one full length of the channel. Craft dimensions: length and width to be under 81.5 cm.

The fuel source must be an alternative to fossil fuel. No dry cell batteries or capacitors permitted.
