Science Rules!

Preschool

The preschool children have been nurturing their curiosity through various science experiments. These experiments play a vital role in the continuous intellectual development of the children, as they are given the freedom to engage in goal setting, planning, and problem solving.

One of the science experiments that we introduced was the inflation of a vinyl glove. After presenting each of the ingredients on the table, Kayla asked, “What do you think will happen when the baking soda and vinegar mix?” Tanner exclaimed, “It’s going to bubble!” Bennett continued, “It’s going to get bigger.” The preschoolers observed the ingredients interacting with in the glass jar. Alex excitedly stated, “The fingers are growing!” The glove continued to grow bigger and bigger. Kayla asked the preschoolers, “Do you know what made the glove inflate?” Owen M exclaimed, “Vinegar and baking soda!” Sweety explained that the baking soda and vinegar are bubbling together along the bottom and creating a gas. Continuing, that it is the gas that is filling up the glove.

After the preschool class explored the reaction of baking soda and vinegar, we decided to introduce the addition of other ingredients, to see what will occur. The exploration of the “Dancing Rice Experiment” allowed the preschool children to experience cause and effect, as well as a chain reaction.
Sweety introduced the “Dancing Rice Experiment” while placing out each ingredient. The preschoolers then explored each through sensory. Individually they smelled the water, felt a rice grain, and watched the ingredients interact with one another. Although the rice did not dance we observed the ingredients separate. Sashin exclaimed, “It danced to the bottom.” While Adam continued, “There all done dancing!” This opportunity allowed for the preschoolers and educators to reflect on why the rice did not dance and what we needed to do differently next time! Alex questioned, “Maybe more baking soda?” Ethan added, “Or vinegar.”

These science experiments ensure the children have hands on experiences that lead to learning through all their senses. Participation in science, technology, engineering and mathematics activities (STEM for short) encourages children to develop their cognitive skills.. It also shows that these experiments don’t always work out the way you predict and sometimes need to be altered and that’s okay.
