Make a volcano!
For a great science experiment that will teach vocabulary and critical thinking, take a plastic cup and fill it with about ½ cup of baking soda and add a couple of drops of red food coloring. Explain to your child that volcanoes sometimes erupt, spewing lava and rocks. You can look at some great videos of volcanoes here and information about them here.
Once you have looked at the volcano videos and talked about lava, rocks, and perhaps even earthquakes associated with volcanoes, begin the experiment.
Tell your child that she will make the volcano erupt by pouring about ¼ cup of vinegar on the baking soda (make sure to place the cup with baking soda inside a small bowl to catch the “lava”). Explain to her that this is not real lava, which would be very hot!
Next, explain that combining the baking soda and vinegar is a chemical reaction. For a simple explanation of this click here.
Be prepared to make the volcano erupt again and again! Have fun!
