Make Playdough:

Recipe can be found online, but here a ratio of 2:1 of Cornflour/Plain flour and cheap hair conditioner used.
Also food colouring gel: red, yellow, blue and black.

Mix big batch of white dough and divide into four to add each colour.

Make Oubleck (Cornflour and Water) - YP can play with oubleck while adults add food colour and mix play dough

Divide up coloured playdough into portions and let YP play.

Reflect/discuss experiment (different texture between Oubleck and playdough) and senses (how does it look, feel, smell)

Show pictures of planets and solar system.
Make into planets - teams of two to make each planet plus sun - discuss what colours to mix together.
Make solar system onto Tuff tray - chalk lines and name tags for each planet first
