Elizabeth's school science fair is this week, and she's been busy preparing for weeks. She decided over winter break to do an experiment with sprouted mung beans. She had 4 sets of beans that were soaked in 4 different liquids overnight and then she measured the rate that each liquid would sprout the beans.
She soaked her first set of beans in vinegar.
The second set of beans were soaked in milk.
The third set were soaked in water.
And the last set of beans soaked in orange juice.
She observed that the growth of the sprout was largely determined by the pH of the liquid, although the milk sprouted a tiny bit better than the water. The vinegar didn't sprout the beans at all, in fact left them hard and shriveled.
A very fascinating experiment for learning about the acidity of liquids and the impact that acid has on sprouting. And now we have some mung beans left to sprout for some sandwiches and salads next week. :)

this is a very interesting experiment, it reminded me of garden soil and how it is very important for it to have all the right components to grow successfully... the correct ph, acidity etc. good job elizabeth!
ReplyDeleteThat is wonderful! (This comment is from a totally objective grandpa ;-) )
ReplyDeleteThat's a great experiment. My daughter has a science fair coming up. Coming up with a good idea to test seems to be the hardest part!
ReplyDeleteI bought some beans and a sprouter/strainer lid thingie a year ago and have yet to use them. MUST do so! well done, Elizabeth!
