Chemapalooza @ Aurora – Wednesday: Water Beads and Diffusion
Today, in Chemapalooza, the students investigated the nature of water beads. Our little chemists used the scientific method to design their own experiment and create a hypothesis on how they predict different liquids or different concentrations of liquids would have an impact on the growth-size of water beads. As the week progresses, the students will continue to work through the experiment and analyze their results and ultimately evaluate their hypothesis.
Ask your student:
What is osmosis? (Osmosis is a special type of diffusion- movement of water across a barrier form high to low concentration)
What is an independent variable? (An independent variable is the variable you are testing in an experiment: it is the variable that is changed)
