7th grade students were learning about water density in science lab. Do you know what happens to water when you add salt to it and why?
Did you know that when salt is dissolved in fresh water, the density of the water increases because the salt adds mass (more weight to the water)? This then allows more objects to float on the surface that would sink in fresh water. This has many practical implications - one of them is being able to swim (or float) in seawater with much less effort than in fresh water.
Middle grades science provides a wide overview of all the major areas of science: physical, earth, and life sciences. Each grade learns about each area, building on the previous year, ultimately preparing for the same sciences on a higher level in upper school. Our middle grades floor has a science lab in order to enhance the hands-on learning that is so important at this stage of development. The curriculum units begin with a review of what they learned in a scaffolding method. The goal is to allow students the opportunity to sample each science and find one that they can thrive in, all the while making connections to the Bible and everyday life.
