Our first grade scientists have made their second attempt in creating carbon dioxide. This time, we got the right ingredient - baking soda (not powder)! Again, we followed the procedure and observed intently of the chemical reaction as the baking soda was mixed with the vinegar. Instantly, the liquid (vinegar) changed its color, from transparent and flat to cloudy and bubbly, creating carbon dioxide. As the gas began to form more and more inside the bottle, the balloon got blown bigger and bigger by the second. Our scientists then recorded the steps that was followed and reflected on what they observed and learned from the experiment.
Then we explored the viscosity (thickness) of different liquids by
playing Racing Drops. Students, working with their partners, were given four different liquids to compare and race... most found out that water had the lowest viscosity...making it
the speediest racing drop, and hand soap had the highest viscosity, which took forever for the drop to reach to the end of the race. Our scientists really had fun in this experiment. This weekend, ask your child which two liquids came in the middle in the race and what properties different kinds of liquids have. Please continue exploring
solids, liquids and gasses with your child at home. We wish we could
continue our experiments in class but it is time to investigate the
solar system starting next week. Enjoy the photos on our weekly slideshow!
