Turn your kitchen into a learning laboratory with just a few household items and have fun with these simple, early science experiments.
Chromatography - What's inside a colour? Water can help you find out!
Cut coffee filter paper into circles and draw a small ink blot in the centre with a felt tip. Then make two cuts in the paper and fold the middle down. Next place the paper on top of a glass of water making sure the strip touches the water.
One colour is often a mixture of several colours. Here, you used water to dissolve the spot of felt pen dye into it's different compounds. These different compounds travel across the filter paper at different speeds, leaving the colourful patterns you see. Scientists call this process chromatography, which means 'colour drawing'.
Build a bridge with a piece of card and two plastic cups. How many carrot slices can the bridge hold?
Try folding the card into different shapes and testing them out.
Strength isn't just about what something is made of, shape is important, too.
An orange has a life jacket!! Yes, it's true!! See for yourself by dropping a small orange into water and then try peeling another and dropping that in too!! Did you think the one without peel would float? Well, the peel is filled with thousands of tiny air bubbles that make it buoyant.
Make some snowflakes with coloured paper or card.
Wrap it around a tall glass and tape into place.
Add a tea light candle and turn off the lights!!
Did your lantern make a snowflake on the wall?
The bright areas of the snowflake are where light passes thought the holes in the pattern. The dark areas are shadows caused when light is blocked out by the solid paper.
Have fun with your little ones and simple science experiments!!! :)
