Ice rings

Children can help make an ice ring one session by gathering herbs and flowers, filling a container with water and putting it in the freezer (or just watching), then on another session they can see what has happened to it when it freezes, and then watch what happens over the course of the session as it melts.

Equipment required

  • Cake ring
  • Water
  • Herbs and flowers
  • A freezer


What do we do?

  • Place herbs and flowers in a cake ring
  • Fill with water and place in a freezer overnight (or two)
  • In the morning remove from cake tin and hang at child height
  • Children can use all their sense to explore the feel, smell and taste of this hanging object, and over time can watch what happens to it as it melts


What are we learning?

  • Using all our senses - see, touch, smell, taste (and hearing if there are two rings banging together in the wind)
  • Sensory experiences - cold, wet, smell
  • What happens when it melts?  Does it melt faster in a sunny area or shaded area?

Bubble prints

Bubble prints are created by blowing bubbles in coloured water and using a piece of heavy paper to take an imprint of the bubbles.  Allows children to experiment with different techniques for creating prints and explore some of science behind making bubbles.

Equipment required
  • Cups of watered down paint, dye or food colouring
  • Dishwashing liquid
  • Straws
  • Heavy paper


What do we do?
  • Add some dishwashing liquid to a cup of coloured water/paint
  • Have the child blow through a straw into the water, creating bubbles
  • When the bubbles have reached the top of the cup, place your paper on top to capture the shape of the bubbles


What are we learning?
  • To follow a process
  • How bubbles can be made
  • Transference and mirror images
  • Shapes (circles)
  • What happens if we make a mistake (tip the cup over, blow too hard/gentle, suck, etc)

Potions



Potion making allows children to experiment with mixing different materials and colours together to discover their own end results.  It allows creative expression and can incorporate elements of fantasy play as children imitate activities they have seen at home (e.g. cooking).

Equipment required:
  • Individual containers for all children (we used ice cream containers here)
  • A selection of scooping and stirring instruments
  • Water
  • Liquid dye with droppers
  • Foam (not shown in first picture), dishwashing bubbles, or other messy play concoction
  • Some kind of plant material (lavender buds are used here, however anything can be used, e.g. grass, petals, leaves, etc)
  • The children should be allowed to add any other ingredients they wish (e.g. sand)
  • Glitter should be discouraged in case children try to drink their potion

What do we do?
  • Allow children to freely experiment with scooping, tipping, mixing, pouring, whichever ingredients they wish.


What are we learning?
  • Fine motor skills (holding cup/spoon, stirring, squeezing eye dropper)
  • Colour mixing/changing
  • Turn taking with other children
  • Measurements (full, half full, etc)
  • Properties of objects in water (floating, sinking, etc)
