Primary 2 Electronics Kit

Primary 2 Electronics Kit

The Primary 2 is a large electronics science kit for children aged 8 to 11 years, and produced in China by the UK based company Cambridge BrainBox, which is part of Akhter group of companies. It covers the National Curriculum for Key Stage 1 and Key Stage 2, and simultaneously makes science fun. It has over 100 experiments involving motors, lights, switches, and sound, and is suitable for home and classroom use.

Snap Board View

The instructions are extremely simple and it all begins with the “Snap Board” for mounting the components. The board has nodule shaped poppers, onto which the snap fasteners connect, and it is instinctive to mount components with this system.


The Primary 2 Kit, costs approximately £24.99, and follows Key Stage 1 and 2 of the National Curriculum, allowing for up to 100 experiments. The Primary plus 2 Kit costs £34.99 and allows for 500 experiments. It is a stepping-stone for Key Stage 3 and 4, and augments Key Stage 3. Both versions come in a large box for storing all the parts.

If you are not sure if your whippersnapper might like these kits, just get the introductory kit, Making Science Fun, however Primary 2 would also be a good place to start. If you find that they are losing interest, then you could also get the Solar Racer and Walking Robot as well. If you have the big bucks, then jump for the Explorer 2, which has over 900, exciting experiments, and costs only £64.99.

Snap Fasteners

Snap Fasteners

The connecting system employs snap fasteners usually found on coats and fabric. Also sometimes known as “Poppers” or “Pop Buttons”, they are usually riveted in place and consist of two halves that make a “Pop” sound when pressed together.

Fan Experiment

Motor and Fan

If your fan does not fly, then chances are that it is rotating the wrong way round. You will need to connect the motor terminals the other way round!



Foam Packing

One of the problems with storage is that if the box turns on its side, all the components fall out of their respective places and mix up. To prevent that from happening, a layer of foam or bubble wrap over the components holds them in place.

Cost / eBay


If your whippersnapper has had all the fun out of the kit and has to move on to the next stage, then why not buy the next Brainbox kit, and simultaneously sell the old one on eBay. If you are just starting out and need to buy your first kit, then Primary 2 is the best place to start. You can get these for a reasonable price on eBay and Amazon.
