Students will explore the three forms of matter; liquid, solid, and gas. In the first activity students will experience all three forms of matter by using vinegar and baking soda to blow up a balloon. In the second activity students identify all three of the states of matter while they make waffles. Students will also use their writing skills to write an explanatory text about the process of making waffles. This activity can be taught independently or can be connected to the National Geographic Reach Grade 3 Unit 5 Mysteries of Matter.
