Most school STEM clubs fail in the same quiet way: the first few sessions are exciting, then the teacher runs out of ideas, sessions turn into lectures or unsupervised free time, and students drift away. The club does not fail for lack of enthusiasm. It fails for lack of a plan. A STEM club weekly activities plan — a full term of sessions, each with a clear task, a materials list, a time structure and a learning outcome — is the difference between a club that survives the term and a club that becomes a memory by midterm. This guide provides exactly that plan, designed for Pakistani schools with ordinary budgets and mixed-age groups.
The plan rests on one principle: every session must end with something students made, tested, or discovered. A session where students only listened is a lesson, not a club session, and students can tell the difference immediately. The twelve activities below follow that principle, using cheap and local materials, and each one can be run in 60 to 90 minutes with a group of 20 to 30 students. A teacher who follows this term plan will never face the blank question of "what do we do this week?" again.
Setting Up a Club That Lasts
Before the first activity, settle the structures that keep a club alive. Fix a weekly slot in the timetable and protect it — a club that meets "whenever possible" meets rarely. Cap membership at a number the teacher and the materials can handle, usually 20 to 30 students, and keep a waiting list so departing members are replaced rather than leaving the club to shrink. Appoint student roles that rotate: a materials manager who collects and returns supplies, a timekeeper who watches the session clock, and a reporter who photographs the session and writes two lines about what happened for the school noticeboard or WhatsApp group.
Set three club rules on day one and enforce them kindly: everyone builds, everyone cleans up, and no one mocks a failed experiment. The third rule matters most, because a club where failure is laughed at becomes a club where only the confident try anything. Frame failure as data: an experiment that did not work taught the group something, and the group should be able to say what. With those structures in place, the activities themselves can be ambitious, because the club has the habits to handle them. Schools that already run structured annual function planning will recognise the pattern: a good club, like a good event, runs on roles, routines and a calendar, not on inspiration alone.
The Term Plan: Twelve Weeks of Activities
Weeks one to three build structures and circuits. Week one is the spaghetti-and-tape tower challenge: teams build the tallest tower that holds a small weight, learning about stability and teamwork while the teacher learns which students lead, which follow, and which need encouragement. Week two is the paper bridge challenge: a bridge of paper and tape spanning a gap, tested with coins until it collapses, which teaches load, structure and honest measurement. Week three is the first circuit session: a battery, a bulb and a switch on a simple board, followed by a circuit quiz where teams wire a working circuit from a diagram.
Weeks four to six move into energy and motion. Week four is the water rocket: plastic bottles, water and a bicycle pump, launched on the school ground with a measured distance competition, teaching pressure and forces in a session students never forget. Week five is the balloon car race: cars built from cardboard, bottle caps and balloons, raced down a corridor, which teaches design iteration because every team rebuilds after the first race. Week six is the egg drop: protect an egg dropped from a first-floor height using only paper, straws and tape, a classic that rewards careful engineering over brute padding. Weeks seven to nine introduce code and control: a block-coding animation challenge, a simple Arduino blinking-LED session, and a sensor session where students measure light or temperature and graph the results by hand.
Weeks ten to twelve bring the term together. Week ten is a design-and-build free challenge: teams choose a problem in the school — a door that slams, a tap that wastes water, a noticeboard that is hard to read — and prototype a solution. Week eleven is testing and improvement of those prototypes, with teams visiting each other's work and giving structured feedback. Week twelve is the showcase: prototypes, rockets, bridges and circuits displayed for other classes and parents, with certificates for every participant. A term that ends in a showcase gives students a reason to finish well, and gives the club its best recruitment event for next term.
Session Shape
Materials and Budget for the Term
The whole term plan is designed to be cheap. Spaghetti, tape, paper, straws, balloons, cardboard, bottle caps, plastic bottles, coins and chart paper cost very little and are available from any Pakistani bazaar or stationery shop. The electronics sessions need a small investment — a few batteries, bulbs, buzzers and, for the Arduino weeks, one or two shared boards — but as a typical 2026 range the full term's consumables for 25 students usually cost under Rs. 5,000 to Rs. 8,000, with the reusable electronics lasting for years. Ask parents to contribute recyclable materials from home — bottles, cardboard, old newspapers — which costs families nothing and gives the club a steady supply.
Store materials in labelled boxes by activity, not in one mixed box where everything disappears. Keep a simple stock sheet: what was bought, what was used, what remains. At the end of the term, the stock sheet and the activity plan together become the handover document for next term's teacher, which is how a club survives a teacher transfer — the commonest cause of club death in Pakistani schools. A club whose plan and materials are documented can be picked up by a new teacher in a week; a club that lived only in one teacher's head dies with their posting.
Making Mixed-Age Groups Work
Most school STEM clubs mix ages, because there are rarely enough students or teachers for separate clubs per class. Mixed-age groups work well when roles are designed for them: older students take design and measurement roles, younger students take building and testing roles, and every team has a mix so that younger students learn by watching and older students learn by explaining. The research is consistent on this point — explaining something to a younger student deepens the older student's own understanding — so mixed-age teams are a learning advantage, not a compromise.
Adjust difficulty within the same activity rather than running different activities. In the bridge challenge, younger teams build for height while older teams build for load-to-weight ratio. In the coding challenge, younger students animate a character while older students build a simple game with scoring. The teacher's job is to circulate with questions, not answers: "Why did that tower fall?" teaches more than "Your tower needs a wider base." Keep teams small — four to five students — and mixed by gender as well as age, because diverse teams produce more creative solutions and because every student deserves a fair chance to build. Good parent-teacher communication about the club's activities also helps, since parents who understand what the club does support it far more readily.
Measuring Whether the Club Is Working
A club's success is not measured by how impressive its best project looks. Measure attendance across the term: a club that keeps 80 percent of its members to week twelve is working, whatever its projects look like. Measure participation within sessions: does every student touch materials every week, or do two confident students build while others watch? Measure the showcase: did every team present something, and did parents and other classes attend? And measure the soft outcomes teachers notice — students asking better questions in science class, volunteering for tasks, persisting when an experiment fails.
Collect this evidence lightly: a weekly attendance sheet, a photograph per session, and a one-page end-of-term note from the teacher recording what worked and what did not. That note, shared with the principal, is the club's case for next term's budget and timetable slot, and it turns a pleasant extracurricular into a documented part of the school's programme. A STEM club that plans its term, documents its materials, mixes its ages well, and ends with a showcase does not just survive — it grows, because students recruit their friends far more effectively than any notice ever will.
