We started our next Science Unit on Chemical Testing. We began our unit by making a list of things we thought we knew about chemicals.
Then, we made a list of things we want to learn about chemicals over the next couple of weeks.
Today, the children were presented with 5 unknown powders. First, they identified each powder's physical properties by using their senses.
Then, they observed each powder's chemical change when we added 6 drops of water to it.
Next, made mixtures by adding our powders to 10 ML of water.
The boys and girls had to determine whether the chemical reaction was a suspension or a solution.
Lastly, they poured their mixtures through a filter into a dish to see what will happen when it sits over the next couple of days in the window (filtration).
They were responsible for taking lots fo notes today! Hopefully by Friday, the boys and girls will be able to use their notes and identify these 5 unknown powders.
Tomorrow we will perform the Iodine, Red Cabbage, and Vinegar tests.
