You Don't Need to Pay for Good Science
P3 is when Science enters the picture in Singapore primary school, and many parents panic-buy assessment books or sign up for tuition before October. Most don't need to. Between MOE's own platforms and a handful of free international resources, you can cover every topic in the P3 to P5 syllabus without spending a cent.
The trick is matching the resource to the topic, and not letting your child wander into content that isn't in our syllabus.
Start With What MOE Already Gives You
Student Learning Space (SLS)
Every Singapore primary school child has an SLS account. It's underused. SLS hosts MOE-curated Science lessons aligned to our exact syllabus, including animations, quizzes, and interactive simulations. Log in via Singpass or your child's school credentials and search by level and topic.
Tip: filter by "ACE Lessons" — these are the higher-quality curated ones, not user-generated.
Science Centre Singapore Online Resources
Science Centre's website hosts free experiment write-ups, downloadable activity sheets, and short explainer videos. Most are pegged to local syllabus topics. Their Lab in a Box archive is excellent for hands-on weekend learning.
Topic-by-Topic Mapping
Here is where the free resources earn their keep — matched to your child's actual chapters.
P3 Science
Diversity (living and non-living)
- BBC Bitesize KS1 "Living things and their habitats" — short videos work well as introductions
- Khan Academy Kids has a free "Plants and animals" unit suitable for P3 reinforcement
- BBC Bitesize "Everyday materials" maps almost exactly to our P3 chapter
- The Royal Institution's Christmas Lectures clips on YouTube show real materials in action
- SciShow Kids on YouTube — search "magnets for kids," ten-minute videos
- MOE-uploaded SLS demonstrations for the textbook experiments
P4 Science
Human body systems
- Operation Ouch! on BBC iPlayer (or YouTube clips) is a Singapore-parent favourite — the digestive system episode covers our chapter exactly
- Crash Course Kids "Human Body" series, free on YouTube
- BBC Gardeners' World "Children" segments
- NIE OER (Open Educational Resources) plant biology materials, free to download
- Generation Genius has free preview videos on light — the full library is paid but the free ones cover the basics
- SLS has solid local-context simulations on shadow length and direction
P5 Science
Cycles in plants and animals
- Crash Course Kids "Life Cycles" playlist
- BBC Bitesize KS2 "Living things and their habitats"
- NASA's "Climate Kids" water-cycle interactive — free and visually clear
- BBC Bitesize "States of matter" videos
- PhET Interactive Simulations from University of Colorado — the Circuit Construction Kit is free, browser-based, and lets your child build circuits without a single battery
- SciShow Kids on series and parallel circuits
YouTube Channels Worth Subscribing To
A handful of channels consistently deliver age-appropriate, syllabus-relevant content. Use the Subscriptions tab, not the Recommended feed, to keep the experience focused.
- SciShow Kids — short, accurate, fun
- Crash Course Kids — slightly older audience, perfect for P5
- Free School — slow-paced and clear, good for P3
- TED-Ed (selected videos) — preview before showing; some are too advanced
- MOE Singapore — the official channel hosts curriculum overviews and specific topic clips
How to Use These Resources Without Burnout
More videos isn't better. A simple weekly rhythm works.
A Sample Weekday Plan
- Monday: 10 minutes — watch one short video on the current chapter
- Wednesday: 15 minutes — try the corresponding SLS interactive
- Friday: 15 minutes — your child explains the concept back to you in their own words
A Sample Weekend Activity
Pick one topic per fortnight and do a hands-on tie-in. Studying magnets? Walk around the flat finding magnetic and non-magnetic objects. Studying the water cycle? Boil a pot of water with a cold lid above it and watch condensation form. The hands-on link is what cements the concept.
A Caution About International Content
BBC Bitesize, Khan Academy, and Crash Course are excellent — but they teach a slightly different curriculum. A few things to flag:
- The UK uses states of matter terminology that mostly matches ours, but some experiments use Celsius alongside Fahrenheit references. Pause and clarify.
- US Science content occasionally introduces topics earlier or later than MOE. Cross-check the chapter heading in your child's textbook before assigning a video.
- Vocabulary differs in places — "torch" in the UK is "flashlight" in US content. Worth a 30-second conversation.
What to Do This Week
- Log into SLS with your child this weekend and bookmark the current Science topic for daily 10-minute use
- Pick one topic from the mapping above and queue up two videos and one hands-on activity for the next 14 days
- Subscribe to two of the YouTube channels listed and unsubscribe from anything that's been pulling your child toward unrelated content
