Science Week lesson plan: Chocolate structures (EYFS/KS1/KS2)

Demonstrate how to use melted chocolate to ‘weld’ together edible items to create super-yummy chocolate structures.

Science Week lesson plan: Chocolate structures (EYFS/KS1/KS2)


  • Lots of chocolate in all shapes, sizes and types
  • Marshmallows, cereal hoops and other small food items
  • Reusable, metal water bottles
  • Hand-hot water


  1. Add hand-hot water to the metal bottle and put the lid on firmly.
  2. Hold the edge of a piece of chocolate against the bottle’s side, keeping hands away from the bottle’s surface.
  3. When the edge of the chocolate piece has melted, use as a ‘cement’ to join it to another piece of chocolate or to other edible items.


When heated, chocolate undergoes a physical change, from a solid to a liquid. As it cools it returns to being a solid. Chocolate melts between 30–40°C which is why chocolate is ‘melt in the mouth’.


  • Can you make a tall chocolate tower?
  • What other super-structures could you make?
  • Does some chocolate make better ‘cement’ than others?
  • How strong are your chocolate structures?

Love to Investigate

Love to Investigate is a set of 126 scientific investigations that encourage children to be curious, ask questions and explore the world around them.

Our series of practical, exciting investigations cover tricky topics in new and unusual ways, including evolution, mechanisms and air resistance. All activities come with background knowledge for teachers who haven’t taught the topic before and method boards to help children work more independently.

Love to Investigate is included as part of Curriculum Maestro and Curriculum Maestro Lite (Love to Investigate is no longer sold separately).

    We are in a much better place with CM than with our old curriculum. We will be making it more bespoke in the second year.

    Conrad Fox – Headteacher, Hunmanby Primary School, England


    I have used Cornerstones from its first launch. The product has been refined over time as it is driven by feedback from schools and teachers delivering the content. The company is also responsive to a school's needs.

    Lindsey Wain – Deputy headteacher, Hartburn Primary School, England


    Maestro is a real time saver, particularly for leadership teams and subject leaders. There is a wealth of information and resources which can be used and adapted by creative skills teachers. The way the curriculum is mapped is excellent and was commented on in a very recent Ofsted inspection.

    Charlotte Gibbins – Thurlstone Primary School, England


    I have recommended and told many other schools and school staff about it. I would always though suggest that they need to ensure it is right for their school setting and the needs of their staff and pupils.

    Kathryn – Teacher, Langton Primary School


    It has been a revelation. Staff are finding their way through it and if we have any questions, the support from Cornerstones is amazing. We always get answers to our questions. It is now our one-stop-shop for curriculum with linked up thinking and approach through an intuitive and user-friendly system.
