We were sent a Great Gizmos Grow A Maze Set to review to celebrate National Science and Engineering Week. National Science and Engineering Week, is a ten day celebration of science, engineering and technology which runs from the 15th-24th March 2013 across the UK and is coordinated by the British Science Association.
As H is a natural scientist with a very enquiring mind, this kit seemed just the thing for us. First of all you need to get the seeds to germinate by placing them on dampened cotton wool. H loved using the little dropper to add water to the cotton wool. Then we placed the seeds. Once we’d done this he wanted to check the seeds progress several times each day.
As the plants get bigger you transfer them into compost and start experimenting with the effect of light on growth. H has had endless fun constructing potential mazes for the young plants to negotiate in their quest to find light. We haven’t finished all of the experiments in the set yet because bean seeds can take about a week to germinate (depending on the variety).
One thing to bear in mind is that the set does not contain the bean seeds or compost, so you will need to provide these separately. I think it would have been a nice touch if these had been included in the set as it adds to the cost if you have to make special purchases to conduct the experiments.
This set is a great way to teach your child, in a practical way, about concepts like:
- the germination process
- roots grow down (there’s a see through holder for the compost so you can see this in action)
- shoots grow upwards and search for light
I like the fact that you can repeat these experiments again and again, so the first time you can talk about roots growing down and roots growing up. Then a few years later you can talk about positive and negative geotropism (the scientific terms for the same traits).
