This is my Christmas acrostic poem. Enjoy!!
Christmas Acrostic Poem
Christmas ornaments decorate the lush, green tree beautifully
Happiness and joy fill people’s hearts with warmth
Reindeer obediently lead Santa’s sleigh with pride, gliding it through the air to deliver presents to the children of the world.
Icing on delectable cookies makes Santa jolly and plump.
Santa enjoys hearing the sweet sound of Christmas carols being sung by choirs.
Tree lights glow and flicker brightly, making houses look festive.
Mistletoe is hung lovingly on the doors of people’s houses to welcome guests.
A special time to appreciate family and friends
Stockings are filled with treats and goodies for those who have been well behaved all year.

Rainbow Water Density Tower
Rainbow Water Density Tower
Aim - To observe how substances with different densities interact
Materials
Glasses - 1 per group
Food colouring (red, blue, green and yellow - you can make purple and orange by combining two colours)
Sugar or Salt (and measuring spoon)
Measuring cup - 1 per colour (you can have 6 colours to work with, or limit it to 4 colours)
Measuring syringes
Water (warm water from a tap or kettle)
Plastic spoons to mix the sugar and food colouring in the water
Pots of water to rinse syringes between each colour
Plastic plates or trays to protect the table from sticky sugar water
Steps (Method) we took to do the experiment:
Put two spoons of sugar in the yellow dye. Put 6 in the red dye. Put 4 in the green dye. Finally,y put 8 in the blue dye. l Get the blue dye and with the syringe collect 200mls. Squirt the blue dye into the glass. Now ow. collect 200ml of red dye. This time carefully, get the syringe, go deep down and squirt. Now get 200mls of green dye. Again carefully squirt slowly. Do the exact same for the yellow. Wash the syringe every time before you add the next coloured dye.
Once you have finished squirting all the colours they should be separated into different lines. If you do it to fast the water will turn balack or dark green.
Results
All of the colours had different amounts of sugar, causing the colours to have different densities and refuse to mix together. Since it won’t mix, it instead makes a tower of all the colours from the first colour(the one with the most density) to the last colour laying on the top.it goe in order from the most density at the bottom and the least density at the top.
Explanation
Look at the websites below and also do research of your own - Then write a paragraph explaining ‘the science’ behind the experiment. Why do we see the results that we did?
