We were very kindly gifted a Letter Box lab subscription box to review as part of our Subscription Sunday series.
Letterbox Lab is a monthly subscription that arrives through your letterbox containing everything your child needs to start playing with science. It’s designed for children aged 6+ and 8+ and although Krystabelle is only 4 this box was perfect for her. I have always known that Krystabelle is quite advanced for her age but I would honestly recommend this box for any four year old.
It’s a great way to encourage children to start experimenting with science at an early age.
There are two different series to choose from, The Investigate Box and The Explore box. The Investigate box is designed for ages 8+ and starts from £20.50 per box (plus £2 postage)
There are 5 to 10 activities in every box and throughout the series you build up an impressive collection of lab equipment and gadgets. From marvellous mixtures, through slippery slimes to dinosaur droppings there’s something for every budding scientist in the Investigate Series.
The Explore box is the box that we received which is the one designed for ages 6+ and starts from £9.50 per box and that also includes postage.
Each one has 3 to 5 fun science activities. The first Explore Box is called Hidden Rainbows, this is the introductory science kit and it’s also the box that we have been lucky enough to review.
When we opened our box we found the booklet and instructions, a spinning top and two paper bags which contained scissors, a petri dish, two rainbow glasses, felt tip pens, a pencil, chromatography paper, coloured sweets and two bottles of salt.
As well as the booklet it also contained a Read Me sheet for the grown ups.
The first experiment was Incredible Inks, Krystabelle needed to find the hidden colours in the inks. Firstly I added some water to the bottles of salt, inserted the dropper tip and screwed the cap on. Krystabelle then gave the bottles a good shake until all of the salt had been dissolved. Next she poured some of the salty water into the petri dish.
Krystabelle then took the lid off one of the felt tip pens and drew a big black line across the bottom of one of the chromatography paper about 2 or 3cm from the bottom and then dipped it into the watery petri dish to see how the colour would run.
Krystabelle also did the same with the sweets.
You can also try some of your very own experiments using the same techniques with different types of paper you may be able to find in your household such as kitchen roll, toilet paper and even newspaper.
And of course you can also use different kinds of sweets or maybe some food colouring too.
The second experiment was Rainbow Glasses. Krystabelle got to colour them in however she wanted, she only really coloured in some scribbles here and there as was very eager to get on with the experiment. She then transferred some glue dots onto the glasses and stuck on the diffraction grating which is a material that contains lots of tiny grooves that make different coloured lights shoot off in different directions. The colours are all mixed up in the white light, travelling in the same direction towards your eyes, but when they pass through the glasses they are split up and you see them as tiny rainbows.
We then moved on to the rainbow spinners, I cut all around the cardboard discs and Krystabelle helped to to push the coloured disc over the spinning top spindle, for this experiment she did not want to take off her glasses.
Although Krystabelle didn’t want to take off her glasses for the last experiment, she really enjoyed experimenting with all the different colours and all three experiments had her full attention, she has the best memory ever, especially for such a young child so I really hope she remembers what she learnt from these experiments for when she starts school in September.
All in all, I would highly recommend this science box for any child who loves learning new things, learning through having fun! You can purchase your box here.
