This is another childhood favourite of mine - and something that we have done before growing beans in jar it's a fantastic opportunity for kids to observe the process of plant growth as the seed is visible at all times.
We used a glass jar although you could easily use a plastic jar but clear glass makes the experiment easier to see (if you are worried about the children using glass then like we did last year we grew the beans on our kitchen window sill which the children can't reach but can easily see inside and outside of the house watching them grow).
Scrunching up Paper Towel J pushed it into the jar and then we watered the paper. From the garden I found a pack of runner bean seeds and explained what they are (J is convinced we are trying to grow baked beans) we talked about how the bean is the seed the same as sunflowers and other seeds that we have been growing in the garden. Demonstrating how to put the beans between the paper and the glass J put in a couple with T observing closely and then T helped as well.
We have added the jar to our window sill nature table and are waiting and watching it grow daily - Last year we did the same experiment as part of the back to basics series E is for Experiments and used Broad Beans which we then grew on the kitchen window sill so that neither J nor T could get the jar off and break it.
It's great to introduce some simple science at home to your kids lives - we've currently got frog spawn in a tank (the tupperware container got too small when J decided we needed more frog spawn to observe) and some seeds growing.
