Stalactites and Stalagmites - create your own

As part of our Geography topic, we are now doing Stalactites and Stalagmites we use this book as our base



(click on pictures)

This is the experiment we are doing from the book



You need 2 jars, a small plate or saucer, washing soda ( we bought ours from Wilkinsons), string, and warm water.




First mix the washing soda with the warm water in the jars, we had put the string in already.



Then put the jars with the saucer/plate in the middle between the jars on a sunny windowsill, it needs to be a warm place.






Then you WAIT !!!

A friend did this experiment and it didn't work the first time, she felt it was because it wasn't put in the right place by a sunny windowsill, we put about 5 - 6 tablespoons in each jar of the washing soda, if our experiment fails, we will probably need to add more. I will keep you all updated on how this one works.

About Stalactites and Stalagmites how can you remember the difference?

I always remembered tites (as tights) as hanging down (from your waist)

I was taught to remember tights come down!! Looks like a great experiment.
