## [Science] DIY Catapult

The 2 younger boys (Jae and El) made a catapult to shoot toy balls at home, accidentally hitting the ceiling fan. *gasp* I quickly showed them how to make a simple one with things we already: 7 ice-cream sticks 3 rubber bands 1 milk bottle cap poster putty (aka white tack) to stick the milk […]

## [Activities] 10 Things We Did During The Haze

Ever since the haze worsened last week, Jae has been having a slight yet persistent cough, so I’ve been voluntarily keeping the older kids away from school. So it’s homeschool time for 3 kids again. What are some things we’ve been doing? Simple Science experiments & math demonstrations following the school textbook topics on mass,

## [Engineering] Building a mini wind-powered car

Due to a persistent cough from the serious haze, Jae (7y10m) has been staying home the whole week. He received a Science kit for his last birthday and we finally got to fix it today. It’s a simple and interesting kit where he explored questions like: Why does the car slow down when turning? Why

## Science kits from… Daiso

I was about to leave a Daiso store in Japan when some Science kits caught my eye. Yes, you read it right, Science kits! At 100 yen (~S\$1.40) each! One of the sets was on Animation. Today, El (5y10m) and I made a phenakistoscope and a zoetrope, which were invented by mathematicians Joseph Plateau and

## [Science] Introduction to atoms & molecules

El (5y6m) has been really into Science recently. Today, he chose the atoms and molecules set from the shelf and asked for a lesson on how to build carbon dioxide. I showed him and then we moved to building water, oxygen and other simple molecules. While we were at the water molecule, he built two

This post is on Science — exploring travel adapters. Vee loves The Young Scientists ® magazine. We’ve been subscribing to it since he was 5.5 years old. Initially we tried the Chinese version (宝宝科学) since he’s learning Science in Chinese at school. However we often had to stop to check the dictionary for technical terms

## [Montessori] Learning about flowers & more

During my morning walk with hubby today, I collected two fallen flowers. Once home, I quickly dug out the printable saved in my laptop for a long time. (Sorry, I could’t trace the author for this set. You may download a fabulous set at The Helpful Garden here)  Jae looked up the flower samples from

## Simple magnets activities

7yo Vee & I read the Young Scientist magazine yesterday and it introduced magnets. I dug out our 2 Daiso magnets and a bunch of paper clips. Some simple activities: explore how like / unlike poles repel / attract see how many paper clips we could link try rubbing and magnetising paper clips My mum

## Egg science & math

A fellow mummy gave me half a tray of kampung eggs. The hospitality among Malaysians is amazing! Anyway, the eggs sparked off some rather interesting conversations & learning: – our commercially-farmed eggs (on the left) are brown; the kampung eggs are pale. Why?!? – the kampung eggs are taller than our regular eggs. Why?!? –
