The Great Lessons - Montessori method Part 1

Every education philosophy have it’s own beauty. As I was looking for good resources to help big L to further his interests in learning Science and Astronomy, I chanced upon The Montessori Method on The Great Lessons. Intrigued, I went to read, research and find out with people whom have prior experiences in conducting this.

There are a total of five Great lessons and the first lesson focuses on the coming of universe and Earth. There are many experiments and hands-on activity that kids will love them.

I love the script and learning activities from Miss Barbara and I follow it closely to ensure that the lesson was carried out correctly. And having said that, I also added a gist of OurJoyOfLearning style into the lesson.

I have done up this learning activity to help big L to record his observations. It includes some parts of Missbarbara‘s script for easier referencing as some Science concepts can be difficult to comprehend. You may download here.

We have watched the first great lesson from Montessori Laboratory. You can access the course for free here,

And special thanks to these mummies and for introducing useful sites for me to conduct the first great lesson.

And instagram @3mm.montessori and @jaslearningwithkids for the useful readings and sites to conduct this lesson.

The beginning

Following Missbarbara's script before conducting the activity, you can ask them questions like draw what did you see while outside today? Draw what do we see at night?

Big L draws rain and tree for day and constellation for night time.

Paper experiment

Purpose : Over the next 5 billion years, the particles continued to join together unable to resist the force. (Missbarbara's script)

Things to prepare

1) A tray of water.

2) Punch hole papers or teared papers

How to conduct?

Get your child to pour the teared papers into the water.

Ask them not to touch the tray of water and only observe what would happen to the papers.

Some papers will move towards each other while some other papers will repel.

You can explain to your child that this is called Force. Thereafter, I got him to draw his observations on the learning activities that I have done for him.

The Milky way experiment

Purpose : Our Milky Way has a hundred billion stars and our sun is only one of them. Our galaxy is not a typical galaxy - only spiral galaxies are rich in the metals our kind of life needs. (Missbarbara's script)

Things to prepare

1) A tray of milk.

2) Food colouring.

3) Cotton buds.

4) Liquid soap.

How to conduct?

Get your child to add some food colouring in the milk. Dip the cotton bud with soap and observe what happened to the milk.

We added some OJOL's style by making a milkyway craft.

Things to prepare

1) Snow Colour paint from

2) Black paper.

3) Spray

The density experiment

Purpose : When it first began to form, the Earth was so hot that it was just made of whirling gasses. As the Earth spun in space it began to cool quickly as its size is so small. The particles at the outer edge became cold and they shrank, huddling together they hurried toward the center of the earth. They then became hot though and as they became hotter they expanded and hurried back toward the edge - the coolness of space. For hundreds of million of years this dance continued. Finally, the particles cooled and settled down. The heavier particles sank to form the core, the lesser particles formed the mantle and the lightest particles remained on the outside and slowly formed a crust. (Missbarbara's script)

Things to prepare

1) Honey

2) Water

3) Oil

4) 3 cups for these liquids and 1 big cup for observation.

How to conduct?

Get your child to pour all these liquids into the big cup to observe what happened. They will observe that oil being the top layer followed by water and honey.


Sink and float experiment

To extend big L's learning on density, we tried the sink and float activity.

Things to prepare

1) Ice-cream stick

2) Clay or playdough

3) Wooden block

4) A bunch of ice-cream sticks

And here are some great phenomena that big L observed.

The clay is the only object that sinks while the other objects float on water.

Here are the books that are great to conduct the Great lesson.

Thank you and I hope that this post has inspired you to try some engaging activities at home with your little ones. The Great lesson is indeed interactive and engaging and big L has enjoyed learning on the origin of universe and planets. Beyond that, I didn't know that we can link Science concepts like force, states of matter and density to it.

Do check out these accounts for The Great Lessons too.
