Making Mixtures

Today in science, students were creating different kinds of mixtures.  Once the mixtures were made, the students decided on best methods to separate the mixtures.  When students mixed gravel and water, students used a screen to separate them.  When students mixed Diatomaceous Earth and water, students decided to use a coffee filter to separate the mixtures.  Next, students mixed salt with water, students immediately noticed that the salt dissolved making separation more difficult.  After further discussion, students realized they are going to need to let the water evaporate in order to get the salt back.  Through this experience, the students realized that the salt water mixture was different then the other 2 mixtures. They learned today that when something dissolves into water, this creates a special kind of mixture called a solution.  Ask your child today about the difference between a mixture and a solution.
