Lesson Context
This KS2 scheme was based on Moving Toy DFES/QCA DT scheme of work. This project was carried out with 44 Yr.6 boys of mixed ability. It follows on from a foundation of developing drawing skills, particularly technical drawing with perspective.
Resources Needed
- Squared paper/tracing paper for designing
- Examples of cam movements to investigate
- Modelling: thin card, wire, corks
- Wooden model- ¾"¨ x 1½"¨ wood, 36cm length each (basic model - 2 x 11cm, 2 x 7cm, Dowel, cams (various sizes), snail, tear-drop, oval(optional)
- Wood glue/filler
- Tools: drill, saw, try-square, ruler, sandpaper, file, and reamer
- Materials for toy top (eg self hardening clay, balsa wood, foam, wire, pipe cleaners etc.
- Finishing- paint, marker pens, PVA (seal, varnish effect)
Teacher Preparation
- Collect various types of cam movement to investigate (eg toys, hand held whisk, mincer, barbecue spit, tin opener)
- If possible make one beforehand to understand the problems the pupils will overcome when designing and making
- Worksheets
- Camera to record development
Project Brief
To design a moving wooden toy with a cam movement for a specific aged child with a particular theme
Design and Manufacture
See QCA DT Moving Toy scheme of work
- Technical drawing skills: using photocopied laminated isometric/oblique drawing paper, practice drawing/ erasing basic forms e.g. stacking cubes
- Investigate cam movement in kitchen utensils/toys, resource objects from home
- Discuss brief, requirement of cam moving toy
- Visual thinking, spider diagram of ideas, collect visual resources for young child's themes
- Card/wire sketch modelling of crank movement
- Plans for model: listing materials, tools, processes, annotated technical drawing with measurements on isometric/oblique paper
- Plan movement/measurement using cereal packet frame, dowel, card cams (cut into shapes)
- Finished wood model
- Measure, cut, and sand 4 pieces of wood for frame
- Drill hole through centre of side panels
- Drill two holes in top panel (if making two drops)
- Drill hole in each cam for 2 offset cams
- Cut doweling for horizontal bar, thread on, position, glue off-set cams
- Assemble frame, glue together
- Push/glue cam on each end for handle and to prevent bar from sliding out, ensure tight fit
- Cut small pieces of doweling for drops, either push on two small cams, or drawing pins
- Make top characters
- Paint
- Draw and evaluate finished model with KS1 pupils, self/group assess
Expected Outcomes
Each pupil develops understanding of crank/cam mechanism as well as carpentry skills. Produce a moving wooden toy with supporting visual/technical designs
All will make the same basic mechanism in a frame which is unrestricted in size, number/size of cams, but the finish and decoration is individual choice according to design. e.g.: illustrate a nursery rhyme, tell a joke etc.
Classroom Organisation
Project took place in timetabled weekly lessons over 1 term inc. learning technical drawing skills, combining 2D and 3D visual thinking, final making, evaluating
Additional Information
Pupils must be aware of health & safety precautions with Risk assessment carried out. Pupils are familiar with/practice measuring, cutting, drilling, and finishing wood. Problems with storage, pupils willing to adapt designs during making, ensure plans state wood measurements, size of drill bit. Measuring accurately is vital and checking before cutting any holes or gluing anything in place. It is important to line up the cam and follower otherwise the mechanism will not work smoothly. When adding colour, be careful the paint does not block the holes
