We thought you might want to put aside technology and worksheets and enjoy a few more creative learning opportunities.
Have a look at these lovely rainbow activity ideas…
Grow a Rainbow
Equipment: kitchen roll, scissors, felt tips, two beakers of water, paper clip, thread.
How to: cut the kitchen roll into a rainbow shape; colour the bottom edges of the side of the shape using the rainbow colours (to a height of around 2cm); tie a piece of the thread to the paperclip and place the paperclip in the top-center of the rainbow shape (to give something to hold it with); place each bottom edge of the rainbow in a beaker of water and watch your rainbow grow.
Taking it further: how long does it take your rainbow to grow? Does it grow at the same rate with other liquids? What happens if you use different colours on each side?
Equipment: 5 beakers; water; blue, green and red food colouring, 4 pieces of paper towel.
How to: place the beakers in a row; fill the middle beaker with water to its brim; do the same with the two beakers at each end; place blue colouring in one of the end beakers, red in the other and green in the middle one; twist each piece of paper towel to make 4 sausage shapes; between each beaker, place one end of a paper towel in one beaker and the other end in the one next to it; observe over the next hour or so. What happens and why?
Taking it further: what happens if the room is warmer/colder? Do different colours produce the same result? Do different liquids travel at the same rate?
Equipment: a single rose (or other flower with a sturdy stem), scissors, 2 different food colouring colours, 2 beakers, water, spoon.
How to: carefully cut upwards from the bottom of the flower’s stem so that the stem opens in two (only cut up to around 10cm); half-fill each beaker with water; into each beaker, place a different food colouring and stir so that the water changes colour; place the beakers next to each other; into each beaker, place one of the flower stem ends (the flower will need to be carefully balanced/lean against something); leave the flower overnight then observe your rainbow rose!
H&S: sharp scissors may be needed for the flower’s stem – this may need adult supervision.
Taking it further: what happens if other colours are used? Is it possible to use more than two beakers of colour? What is happening and why?
