22nd September 2016 - Lava Lamps!

 

This week the children voted to make their own lava lamps. This is a fun activity that you can do at home with your child and you only need three simple ingredients!

 

Equipment:

 

  • A bottle (large or small), or a cup. If you use a bottle I would advise using a funnel.
  • Oil
  • Water
  • Food colouring
  • Salt or alka-seltzer

 

Method

 

Using a funnel, fill the bottle 3/4 with water. Add some food colouring to just slightly change the colour of the water (this will make it easier to see the bubbles). Add 1/4 of oil to the bottle. Wait for the oil and water to separate and settle. To create the bubbles you can either add one teaspoon of salt to the mixture, and watch as the bubbles form as the salt dissolves, or you can add an alka-seltzer. Try experimenting with both options and see which one you enjoy more. 

15th September 2016 - Slime!

 

Today we have had great fun creating slime! The slime should last approximately two weeks in an air tight container. The slime does contain washing powder, so please reiterate to the children not to put the slime in their mouths.

 

The children have had such fun an enjoyment over making the slime I have included the recipe below, so you can make more at home together. If you have any questions please don't hesitate to contact Mrs Farrell.

 

Ingredients

 

  • PVA glue
  • Aldi Almat laundry gel. Sadly, not all laundry detergents create the borate ion when added to water and will not create slime.
  • Water
  • Food colouring of your choice and glitter.
  • Bowl and teaspoons.

 

Method

 

Using a teaspoon, add 5 level teaspoons of PVA glue to a bowl. Add one teaspoon on water to the glue and mix until incorporated. At this stage add a few drops of colour to the glue and any glitter you want to add. Mix well. One teaspoon at a time add the laundry detergent to your PVA mix. Mix well before adding anymore. If the glue is making sticky strings to the side of the bowl, add more detergent a half teaspoon at a time until it forms a smooth lump. Take the slime from the bowl and using your hands stretch and fold the slime until it is malleable. 

 

If you make a mistake with your slime, for example it breaks apart and becomes slippery, you have added too much detergent and need to counter it by adding more glue.
