Science fun – Is the beachball heavy?

So Teddy let’s have some fun……..

Looks like the beachball is bigger than Teddy 🙂

A fantastic way to show the concepts of big small /light and heavy-

Fun and very effective.

You can have great fun with your child/children – let them feel the difference in the weights.

You will need – Beachball, Basketball, table tennis ball, golf ball.

Explore the concepts

The golf ball is small but feels heavy

Allow the children to take turns examining the balls.

Prepare for giggles as they feel the difference in weights.

This is a very tactile concrete experience

What does the Basketball feel like? Is it rough or smooth….

This experiment is great for increasing vocabulary.

Chat to the children – making sure to include words like for eg.

Heavy – light – big – small – big – bigger – biggest – rough – smooth

Soft – hard – softest ….

Smaller than – heavier than – round – sphere

NB- remember the importance of open ended questions.

Expand on the above Experiment

The following can be explored but with safety in mind and only under strict supervison

 Have the children test out how the balls roll. What happens when you kick or throw the beachball.

Compare to trying to kick or throw the basketball .

Let the children take turns to roll the balls. You could investigate which ball bounces well.

Does a golf ball bounce


See how the above experiment may link into the Themes, Aims and learning goals of Aistear The Early Childhood Curriculum Framework


Aim 2 Children will be as healthy and fit as they can be.

Lg. 1. gain increasing control and co-ordination of body movements

They will feel the difference in the weight of the balls but also have to control their movements so they don’t drop it.

l.g. 3. discover, explore and refine gross and fine motor skills


Aim 1 Children will learn about and make sense of the world around them

Lg. 1. engage, explore and experiment in their environment and use new physical skills including skills to manipulate objects and materials

This experiment is a great way to help the children move towards achieving this learning goal.

Lg. 6. come to understand concepts such as matching, comparing, ordering, sorting, size, weight, height, length, capacity, and money in an enjoyable and meaningful way.


Aim 2 Children will use language.

Lg. 1. interact with other children and adults by listening, discussing and taking turns in conversation

The children will be interacting with the adult and their peers discussing what the balls feel like –

For example – Which ball feels the heaviest?

l.g. 3. use an expanding vocabulary of words and phrases, and show a growing understanding of syntax and meaning

See how this may link into the Aistear framework


Aim 2 Children will develop and use skills and strategies for observing, questioning, investigating, understanding, negotiating, and problem solving, and come to see themselves as explorers and thinkers

They will be investigating the difference in weight and size of the objects and noticing how even though the objects look similar they are very different in many ways.

Lg. 2. gather and use information from different sources using their increasing cognitive, physical and social skills

l.g. 5. develop higher-order thinking skills such as problem-solving, predicting, analysing, questioning, and justifying

l.g. 6. act on their curiosity, take risks and be open to new ideas and uncertainty


Aim 4 Children will see themselves as capable learners

l.g.4  demonstrate dispositions like curiosity, persistence and responsibility

They will be encouraged to be curious and try out different ideas whilst being careful.
