The Newton Show – Home Science Experiments for Kids

Science can be so much fun. Kids love discoveries. They love the world around them. Simple science experiments can be crafty too. Each week the Newton show will virtually explore  ‘at home science experiments’ for kids. We will look at life science, physical science and planetary science.

 


Life Science- The Hot and Cold – DO  NOT BE NERVOUS!


 

It would be great to always tell the difference between hot and cold.  Now let’s talk about skin. Do you realise that without skin you couldn’t tell the difference between thick and thin, smooth or rough? It is all about the nerves!

Nerve endings send out signals at every second, That is a lot of information for the brain to process. How does th e brain keep up?

It ignores. It uses a process known as habituation to keep from overloading. New sensations like cold water splashed on you or if you stub your toe gets immediate attention,

Everyday things like putting your shoes on do not get the brain excited. The nerves in your feet send out messages to the brain, but the brain is not paying attention. Habituation is followed to make the brain deal with what is important

Home experiment to test your nerves: The  socks method

 

Make sure you wear pants or shorts. If you choose pants, roll them up your legs and take off your shoes.

Spend time doing an activity that takes attention like a puzzle

Now it is time to put on the socks. Keep your eyes closed and try to locate the tip of the socks. You most probably will get close.

 Keep the socks on and go back to you puzzle

After some time, close your eyes and try pointing the tip of socks again.This time it will be harder.

 

What has happened?

The first time the socks was a new sensation. The brain paid attention to the socks, it was easy to find the tips.  When the brain started concentrating on the puzzle it became harder to find the tips the second time.  The same happens for smell or taste. Once there is a habit it is not noticeable.

 


Physical Science: Marvellous Marbles


Marble Paper experiment

Marble Paper Creations

This is where art needs science to come together!

What you need:

White construction paper

Food colouring

An Aluminium Roast Pan

Cooking Oil

Plastic cups

Fork

Lay out three plastic cups. Measure on a tablespoon of the cooking oil and a teaspoon of food colouring in each cup. Beat the mixture well.  This can take up to three minutes. Use different colours.

 

Fill the aluminium pan with a small amount of water.  Pour the mixture of food colouring and oil into the pan. Watch the oil spread in sparkles of colour.

Lay the white paper on top. After thirty seconds carefully lift it. Hang the marbled paper up and leave it to dry.  There you have it. Homemade decor of marbled paper!

How was it created?

Oil floats on water since oil weighs less than water. That is why oil spills are bad for the environment.  A little oil spreads quickly to cover a large area. It is why the mixture spread out in the pan. Marbled!

 


Planetary Science: How does the wind blow?


 

This is a very simple science experiment and it is crafty too. It will work best on a day when it is windy.

Get together a kitchen roll tube, cut tissue or crepe paper strips.  Stick the strips on the inside of the tube and hang the tube out in the wind. Watch the wind blow the tube.

Make a pinwheel and watch the power of the wind. This is a great activity for young children

 

    Cut out a square of paper

    Fold the square and unfold it

    Make pencil markings  about one-third away from the centre

Cut along the folds

 

Pull each point to the centre

 

The head of the pin will form the pinwheel centre.  Stick beaded pin stick in the dowel. and there you have it.Pinwheel ready to fly with the wind.

 

 

 

Other ways to learn which way the wind blows is by getting out there and about flying a kite. Let the wind blow you to the next Newton Show in a region close to you coming soon….
