Plastic Fantastic explores chemical engineering in activities designed to develop understanding of materials and product design. Pupils will gain a nuanced understanding of plastic as a material through identifying environmental concerns whilst appreciating its properties. They will develop practical skills of measuring and following instructions during the skill builder. During tinker time, pupils will have the opportunity to use the plastic they made; either expressing themselves through a craft activity or 'thinking like an engineer' through a real life design challenge.
EXPLORATION
EXPLORATION
Pupils explore plastic as a material by thinking about its uses. Pupils will create a 'my button adventures' story to introduce them to buttons in preparation for the skill builder.
SKILL BUILDER
SKILL BUILDER
Pupils will make their own bioplastic using a step by step guide. The type of plastic they are going to make is called casein. It was used in the early 1900s mainly for making buttons.
TINKER TIME
TINKER TIME
There is a choice of activities for this Tinker Time. Pupils can get creative and express themselves with their casein and craft supplies or 'think like an engineer' to solve a real life design challenge making a bespoke pencil grip.

Yahaya & Charles - Chemical Engineers
This project has been inspired by Yahaya & Charles, Chemical Engineers. To help children better understand what engineering is and what engineers do, it is important that they have the opportunity to meet some (even virtually!) Use this video to introduce real engineers to your class.

There are 2 exploration activities for the Plastic Fantastic project.
The first introduces pupils to plastic as a material
The second gives children the opportunity to explore buttons in a very child-led way. It begins by asking pupils to explore buttons they can find at home. Pupils will continue in class by choosing a button from a selection in class. They will:
Choose the ones that interest them
Touch them
Describe them
Imagine where they came from and what they have seen

Buttons (You could ask pupils to bring in some of the most interesting buttons they can find from home too)
Can we turn milk into plastic?
(approx. 1 hours)Can we turn milk into plastic?
Pupils will follow the instructions to make a milk-based bioplastic (Casein plastic) that was widely used in the early 1900s - particularly to make buttons.
Pupils will need to do the Tinker time activity immediately after this skill builder (before their plastic sets hard).
Therefore, pupils will need to know what they are going to make before they begin this task (see the Tinker time activity below).
You may wish to give pupils a choice about whether they do a craft or engineering based activity or you can decide.

200ml full fat milk per pupil (warmed for 1 minute in the microwave)

Paper towels for cleaning up / absorbent surface for drying out models
Cookie cutters or playdoh cutters (optional)
Food colouring/powder paint (optional)
What will you use your Casein plastic for?
(approx. 2 hours)What will you use your Casein plastic for?
You have a choice of activity here. You may wish all pupils to do the same activity or perhaps match the activities to the interests and skill level of your pupils.

Use these slides to give your pupils a design problem to solve with their casein plastic!
For this Tinker Time, pupils will need to have made their prototypes before they make their Casein plastic
Explain to pupils that rapid prototyping with mouldable materials is a technique used by engineers. It helps them to be able to use the maker{cycle} (look, think, make and test) without having to make lots of Casein Plastic which might be time-consuming and expensive

What useful thing can you make out of polymorph plastic?
What useful thing can you make out of polymorph plastic?
Polymorph is a relatively inexpensive mouldable biodegradable plastic with a low melting point making it easy for children to use.
It would be great to set as an extension activity, a maker club activity or home project

We understand that there are elements of these projects that may be new to you or that you feel unsure about having a go at. If there are things you are unsure about or want to ask questions, please email Alison Buxton alison.buxton@sheffield.ac.uk so we can support you.
Don't forget to take lots of photos and videos for your show reel to show at our celebration event.
