Some parts of the primary science national curriculum positively fizz, crackle and pop with excitement. Which child hasn’t been wowed by the wonders of the solar system or grossed out by the way marsupials give birth (probably worth a google)?

Other parts, such as solubility, are about as exciting as, well, a cup of tea.

What they’ll learn

• Some materials will dissolve in liquid to form a solution
