Group project example
A group project presentation that shows the research and who did it
A four-person college seminar on a plastic-free campus, for students presenting group work. It reports six weeks of bin audits, a survey and interviews, compares rewards with charges from a café trial, sets out the group's proposal and credits each member's part.

03Section
What we found
Six weeks of bin audits, a campus survey and four interviews.
04Key numbers
Campus bins 9,400 plastic items every week
Most of the waste comes from just two places: the main café and the library vending machines.
- 9,400 — Plastic items a week
- 62% — Of bin waste is plastic
- 412 — Students surveyed
- 78% — Would use a refill station
05Chart
Reusable cups caught on once the café offered a discount
Chart: Disposable, Reusable across Week 1, Week 2, Week 3, Week 4.
- Disposable: Week 1 1340 · Week 2 1290 · Week 3 1050 · Week 4 880
- Reusable: Week 1 110 · Week 2 140 · Week 3 360 · Week 4 520
Daily cups at the main café. A 20p discount from week 3 nearly quadrupled reusable cups.
06At a glance
Our research at a glance
- Price beat posters in our café trial — Two weeks of posters barely moved behaviour. A 20p discount on reusable cups cut disposable cups by a third in two weeks.
- 412 survey replies — From all five faculties.
- 4 interviews — Staff and union officers.
- 6 bin audits — Every Friday, 3 sites.
- 3 refill points — For 9,000 students.
07Points
Three things stop students going plastic-free
None of them is a lack of interest: 81% said they care about campus waste.
- There are only three water refill points, and two of them are in buildings most students never visit.
- Reusable cups cost £8 at the union shop, while a disposable cup is free with every drink.
- Recycling bins are labelled differently in every building, so 40% of plastic ends up in general waste.
08Two columns

How our project came together
- Week 1Chose the topic and split the research into four strands.
- Weeks 2–4Ran bin audits, the campus survey and four staff interviews.
- Week 5Trialled the cup discount and the cup charge with the café.
- Week 6Analysed the results and wrote our proposal for the union.
12Process
How we ran our research
- AuditCounted plastic in bins at three sites every Friday.
- SurveyTen questions, shared through course group chats.
- InterviewSpoke to café, estates, union and staff.
- TrialTested a discount and a charge for two weeks each.
13Composed
Our proposal follows a student's day from first coffee to last bin
- Arrive: Buy a coffee at the main café (Student)
- Discount: 20p off with a reusable cup (Campus)
- Refill: Water points beside every lecture hall (Campus)
- Sort: Matching bin labels in all buildings (Campus)
- Return: Borrowed cups back at any café (Student)
Rollout
- Term 1: discount and labels
- Term 2: six new refill points
- Term 3: cup-loan scheme
Action Who leads Cost 1 Reusable cup discount Café manager £1,200 a term 2 Six refill stations Estates team £4,800 once 3 Matching bin labels Students' union £350 4 Cup-loan scheme Students' union £900 a year Why it will work
- Low cost: Under £10,000 in year one
- Student-led: The union owns two actions
- Measured: Bin audits repeat every term
Our target: Half as many disposable cups by June

Refill points students will actually use
Our survey map showed students walk past the library and lecture halls most. We propose six new refill points along that route.
- Placed on the busiest walking route
- 78% of students said they would use one

Questions
Give each person a section they researched, and say so on a 'who did what' slide like the one in this example. Agree on one storyline first, so the handovers between speakers follow the argument rather than the order you worked in.
