Air Transportation

Air Transportation

Science Experiment by Mummy Jing Er

Science activities and experiments encourage children to ask questions and promote scientific thinking such as making predictions, observations, comparison, reasoning, data gathering, experimentation and evaluation.

Other Learning Opportunities:

  • Language development: Using descriptive words to express ideas and opinions.
  • Cause and Effect
  • Concentration

My son is very familiar with normal air transport as he is fascinated with air planes. I wanted to show him that not all air transportation works on engines. Hence, I introduced the hot air balloon to him.

First & foremost, show your child the following YouTube video on the hot air balloon to let them have a better understanding of what a hot air balloon is.


1. Two containers

One filled with hot water and the other with ice and cold water.At first, we could not get the balloon to ‘stand’ when it was in the hot water but I changed the container to a narrower one so that the hot water can cover the entire bottle. The effect was better.

2. One balloon

3. One empty plastic

The larger the bottle the more room the air has to push up and expand.



  1. Do get your child to make predictions and question before conducting the experiment. “What will happen to the balloon when the bottle is in the hot water?” “Why?”
  2. Blow the balloon up to stretch it and help make it more flexible and let the air out.
  3. Place the balloon over the mouth of the empty plastic bottle.
  4. Stand the bottle in the centre of the container filled with hot water. Wait a few minutes and notice the balloon start to inflate and expand.
  5. Remove the bottle from the hot water and place it in the container with cold water and ice. Wait a few moments and notice that the balloon starts to deflate and contract.

My boy was very excited! He was fascinated with how the hot air can cause the balloon to inflate. He wanted to do the experiment again and again.

‘Purposeful Craft’ by Janice Ong

I love crafts because it is a great way to bond with your child and spend time to create something together!

Other benefits of Arts and Crafts:

  1. Bilateral Coordination
  2. Fine Motor Coordination
  3. Self-Regulation
  4. Self-esteem booster

I decided to do ‘Purposeful Craft’. It is a craft done with an objective to learn beyond craft! This sounds weird!

Materials you need for ONE aeroplane:

  1.  One wood peg
  2. Three ice-cream sticks. Two in its original length and the other snipped at the ends.I did not have ice-cream sticks with me and used corrugated board instead
  3. Double sided tape or glue


I got my boy to assemble and create 5 aeroplanes!

AP5   AP8

With a marker, hanger and some paper strips, I created this to enhance the purpose of the craft.


I got my boy to fly his aeroplane as if he was in a race! The first aeroplane to reach the hanger would get into 1st position and so forth. Here, he was being taught ordinal numbers. I did it in both English and Chinese. This purposeful craft aids in fine motor skills when he was attaching the aeroplane to the strips.

My boy had fun and learnt a great deal! I even got him to award each plane with a ‘star medal’ to reinforce the concept of ordinal numbers.
