Mixtures and Solutions Concepts

In this video, Holly from the Lighthouse Lab introduces viewers to different types of mixtures: solutions, suspensions, and immiscibles. Through simple experiments, she demonstrates how salt and sugar dissolve in water to form solutions, sand remains suspended in water, and oil does not mix with water, forming an immiscible mixture. The video encourages viewers to try these experiments at home to better understand the concepts.
