    Please note: Two week's notice is required for a refund for cancellation.


    If you are a STEM Den 'regular' and have completed the activity already on offer on the day you would like to attend, then please do email Mrs McSween as quite often we can tailor the program to accomodate your specific needs. If you are building a portfolio for a STEM or DT&E scholarship this could be you!


    Monday 12th February - Lanterns of light

    We couldn't resist the opportunity to build our own lanterns using willow and tissue paper. Learn about strong framework structures both 2D and 3D and how they are used in the world around us. Take home your creation to put in the garden. NEW!


    Tuesday 13th February -  Mesmerizing Mechanisms

    Have fun learning by playing with gears and levers. Design and make projects which can be taken home. Outcomes will be different depending on age and experience.


    Wednesday 14th Feb - 'If you were an Engineer what would you do?' National Competition

    Join in an interview with engineer Amanda May from the National Grid. Talk about what it takes to be an engineer and the different types of engineer. Have fun preparing an entry for the national competition ‘If you were an engineer what would you do?’ We can send off design work to the competition if it is ready or work on it a bit more at home and send it in yourself, NEW! Click here for further information. 

    VEX Go, VEX IQ or Lego WeDo kit building and programming for the rest of the day!

    April 2024


    Monday 8th April - What floats my boat?

    Investigating how things float and the science behind it. Make your own boat using reclaimed materials. Consider how it will be powered and what its role will be. Child centered learning about different types of boat. Boats can be taken home.

    Crest Award Day


    Tuesday 9th April - Double Duo

    Woodland Activities for one half of the session. Outdoors, building dens, learning about knots and looking carefully at nature in our beautiful School grounds. In the other half of the session, use VEX robotics (or our younger studentsLego WeDo) to build and program in real life situations. Woodland crafts can be taken home.

    Crest Award Day 


    Wednesday 10th April - Wobblebots

    Learn how to connect together a simple circuit. Learn about conductors and insulators along the way as you make your own switch. Find out about flywheels and cams as we make an off centered cam which should make our reclaimed materials ‘wobblebot’ move… all over the place.

    Crest Award Day


    Thursday 11th April - Back to the Future Challenge!

    As this year’s Science week was based on the theme of TIME, then it is most appropriate for a TIME related challenge. Work in teams to solve the puzzles, collaborate to engineer a solution to get Marty back to 1984 on this exciting and fun day. (from the film Back to the Future)

    (Nothing to take home apart from hopefully a smile.)

    What are the Science Crest Awards all about?

    Plan, carry out and evaluate your own STEM based investigations to achieve a Nationally Recognized Award. Children aged between 5 and 10 will need 8 investigations all stamped off in their book, Children aged 10 and above take an all day challenge. Click here to find out more.


    VEX robotics kits will be available every day on request, depending on availability. There are two different levels of kit depending on age and experience. We have VEX GO and VEX IQ. For our younger students from Rec to Year 3 we have VEX 123 or Educational Lego kits are ideal to start the journey of programming. For our youngest students aged 5 to 7 we suggest this is taught in small bitesize chunks around half an hour long. Click the link to find out more.


    Our LEGO, CRUMBLE and VEX kits are to be used within the camp only and cannot be taken home. You might like to buy a CRUMBLE kit. They are available from Redfern electronics to purchase for around £25 and can be used for hundreds of other project ideas. Software for this is a free download. For more details click here.)

    We may make changes to our program from time to time without notice but do our best to stick to the plan as much as possible. Adaptive teaching allows us to tailor the sessions to accomodate the children being taught, please do not be surprised if our advertised plan of action changes its course.
