1. Boil the solution: Heat the saltwater mixture in a container until the water evaporates.2. Collect the salt: As the water evaporates, the salt will be left behind in the container.This method works because salt doesn't evaporate as easily as water, so it remains behind as the water turns into vapor.The students can also use a "simple distillation" setup to collect the water and separate it from the salt.This method is a fun and easy way for grade 6 students to learn about separation techniques and the properties of mixtures!
