Sixth grade scientists are learning about the makeup of substances in the unit Mixtures and Solutions. They are gaining knowledge about how things go together and how they can be taken apart. Learning about changes in substances is important because changes can be controlled to produce new materials. Recent investigations include:

• Testing for water quality in a watershed
• Oil Spill
• Acid/Base Fizz Quiz
• Creating elephant toothpaste
• Designing a bouncy ball

Sixth graders discussed their favorite solutions. Some included the ocean, the air, and lemonade. What is your favorite solution?
