Designing your TerrariumUsing 2 d design draw your pieces for making your terrariumSelect the shape tool and say you want 5sides this will make a pentagon then saywhat length of side you want ok.Then select using the arrow tool and press the copy iconAnd tessellate as this will save materials.Make sure you makeenough shapes for thecomplete terrariumNow save and export to the laser cutter.
I have looked at how other designers use materialstessellations and how I can make a terrarium6I have looked at the materials I have used and haveshown I understand where they come from.5I understand why we need to use greenhouses foragriculture.4I Have looked at how architects use tessellation?3teacherlevelyouAF1 Understanding design and technology in societyAF 2 DesigningI have implemented maths theory about shapesand angles and used it creatively.6I have designed using sketching and CAD (googlesketchup)5I have built a successful model of a geodesic dome4I have looked how designers use tessellation in mydesigns.3AF 3 Making and reviewingI have tested and evaluated my product and suggested three sensible improvements6I have investigated how to join acrylic.5I have used CAD/CAM to make my panels4I have modelled my own terrarium from card3Designing skillsClarification and communication skills Aesthetic and sensory knowledge and understandingWorking and refining design briefModellingDeveloping existing productsUse of CADDesigning through exploring materials, Sketching on paperDesigning on paper modelling in cardImproving on prior knowledge of the builtenvironment,Understanding of the role of architects.Use of google sketchupdesigning using CADScientific and technological knowledge Materials and processesand understandingInfluences and issues moral ,cultural historical environmental etc.Using information from scientific testing on colour on growth toUnderstanding of how the development ofgrowth can be improved with correct condi-Using acrylicUnderstanding CAD /CAM (laser cut-
