Description

Moon Sand

Resources

 8 cups plain flour
 I cup of baby oil (or any oil if you prefer)
 Plastic Moulds
 Pastry Cutter
 Spoons
 Mixing Bowl

Instructions

Aim of Badge To discover STEM (Science, Technology, Engineering and Maths) in an easy and fun way through simple experiments and activities.

This Badge has 12 options of which 5 must be completed
(1 Leader Demonstration Option and 4 Ladybird Options)

Introduction
• Moon sand is given its name because of its crumbly texture and how similar it looks to the surface of the moon.
• It can also be molded when compressed, making it excellent for open ended play!

Instructions
1. Place the 8 cups of flour in mixing bowl
2. Gradually add the baby oil
3. Stir well.
4. Transfer your dough to a bin or basin
5. Place pastry cutter, plastic moulds and spoon in basin
6. Encourage Ladybirds to experiment and enjoy making shapes

How does this experiment work?
 The presence of this hydrophobic compound ((causes the grains of sand to adhere to one another and form cylinders (to minimize surface area) when exposed to water.
 When the sand is removed from water, it is completely dry and free flowing.
 Magic sand is also known as Aqua Sand. Moon sand is also known as kinetic (moving) sand, or cloud dough

Examples of Hydrophobic Substances. Oils, fats, alkanes, and most other are hydrophobic. If you mix oil or fat with water, the mixture will separate. If you shake a mixture of oil and water, the oil globules will eventually stick together to present a minimum surface area to the water.
