A Galaxy Far, Far Away — From Your Living Room
May the 4th is the perfect excuse to turn screen time into STEM time. The Star Wars universe is packed with science your child can recreate at home — orbital physics, robotics, simple machines — and most of these activities cost less than a kopi at the void deck. Pick one or two for the school holidays and watch your child engage with concepts they will meet again in P5 Science and beyond.
Coding: Program a BB-8 Maze in Scratch
Scratch (scratch.mit.edu) is free, browser-based, and used in many MOE schools' Code for Fun programme. Building a droid maze takes about 90 minutes and reinforces sequencing, loops, and conditionals.
What Your Child Builds
- A small grid maze (sprite background drawn in Scratch)
- A BB-8 sprite that moves with arrow keys
- "Stormtrooper" sprites that patrol on a loop
- A win condition when BB-8 reaches the Resistance base
Why It Works
This project sneaks in real computational thinking: your child has to break the problem into parts (movement, collision, win state), debug when BB-8 walks through walls, and iterate. A P4 student in Tampines spent an afternoon on this and ended up adding a "Force shield" power-up of her own — that is the moment learning becomes play.
If your child is brand new to Scratch, start with the official "Animate a Name" tutorial first, then move to the maze.
Physics: Paper Stomp Rockets
Forget the lightsaber duels — the most photogenic activity is a paper rocket launched by stomping on a plastic bottle. It takes 20 minutes to build and demonstrates Newton's third law beautifully.
What You Need
- Empty 1.5L plastic bottle (Ice Mountain, F&N — anything works)
- 1.5m of garden hose or PVC pipe (Daiso has both)
- A4 paper, tape, scissors
- Duct tape to seal the bottle to the hose
How to Run It
- Roll an A4 sheet around the hose to form a tube; tape the seam.
- Fold and tape one end shut; add paper fins near the open end.
- Slide the rocket onto the hose. Stomp the bottle.
- Measure how far it flies. Change one variable — fin size, nose weight, paper thickness — and try again.
Engineering: Cardboard X-Wing Build
A flattened delivery box from your last Shopee order is enough to build a respectable X-wing. This is open-ended engineering — no instructions, just constraints.
The Brief
- Wingspan no wider than 60cm (so it fits through your front door)
- Must have four "S-foils" that open into attack position
- Must balance on its landing gear without tipping
Extension for Older Kids
P5 and P6 children can add a simple lever to make the S-foils open and close from a single pull-string. This connects to the systems strand of the upper-primary Science syllabus.
Astronomy: A Two-Sun Sunset
Tatooine has two suns. Your child can model why that looks the way it does using two torches and a tennis ball.
- Darken a room. Hold the tennis ball (planet) at arm's length.
- Have your child shine two torches at it from slightly different angles.
- Notice the double shadow on the wall behind.
Robotics on a Budget: Brushbots
If your child already loves coding and wants something physical, brushbots are the cheapest entry into robotics.
Parts (under $10 total)
- One toothbrush head (the angled bristle kind works best)
- One small vibration motor (Sim Lim Tower, level 3, about $2)
- One coin-cell battery and holder
- Double-sided tape
Tying It Back to School Learning
These activities are not just holiday filler. Each one connects to the upper-primary syllabus your child will meet this year.
- The Scratch maze develops algorithmic thinking, a thread woven through the MOE Code for Fun curriculum.
- The paper rocket and the brushbot both require a fair test — change one variable, keep the others constant — which is exactly how P5 and P6 Science experiments are graded.
- The cardboard X-wing build rewards iteration and prototyping, the soft skills that pay off in any project work later in secondary school.
What to Do This Week
- Pick one activity above and block out 90 minutes — Saturday morning before the heat sets in works well.
- Take a short video of the build and the result; your child can narrate what they learned.
- Bookmark Scratch and the NLB e-resources for more guided projects during the June holidays.
