My son turned 5 last week and I’m happy to report that we’ve seen some huge leaps in his fine motor skills development in the last month. WJ is so much more confident using a pencil to write letters and has moved on from his Lego Duplo sets and now spends hours working on his “big boy” Lego sets. It is truly amazing to see his development from just 3 months ago when he would get so frustrated at not being able to handle the smaller Lego pieces and would erupt into a full blown tantrum. Don’t get me wrong, he still throws tantrums but there are not nearly as many as before.
This week we spent time working on a science experiment — the Erupting Rainbow Volcano Experiment. WJ got a new science kit for his birthday called My First Mind Blowing Science and he couldn’t wait to try out the experiments.
This experiment from the kit required the use of a pipette to carefully measure liquid and drop the liquid into it’s location and WJ did really well, with very little help from this momma.
Here’s a picture of the science experiment:
We molded a volcano out of a paste of baking soda and red cabbage powder. Then we added a little purple water around the volcano. The next step was to create the explosion. WJ dropped a little water and citric acid into the middle of the volcano with a pipette and voila, an explosion. The volcano started foaming with a burst of bubbles and the purple changed to blue as the citric acid came into contact with the volcano.
Some science concepts we discussed:
- The change in color is because the baking soda is a base and turns the red cabbage juice blue.
- When an acid is mixed with a base, a chemical reaction occurs. In this case, we had foaming bubbles and changing colors.
You can recreate this experiment with more colors with food coloring.
You can click here for a similar experiment you can try out home without the kit, just using food coloring, baking soda, and vinegar.
WJ loves anything that erupts and the more colorful the better so I’m sure we’ll be doing this experiment again very soon.
Happy experimenting with your preschoolers!
