Evidence of a Chemical ReactionOur state standard is 6.5D identify the formation of a new substance by using the evidence of a possible chemical change such as production of a gas, change in temperature, production of a precipitate, or color change.
In order to understand this, students must be able to differentiate between a physical and chemical change. They must also explore the different types of evidence that can indicate a chemical change. |

Ms. Jones has made a quizlet!There are different ways to practice with vocabulary for physical and chemical, including flashcards and games. If you play the Gravity game, make sure to set "Start With" to Definitions (the second choice down)

Digital Lab to practice Physical and Chemical Properties and ChangesWant to check your answers? Go to Google Classroom (classroom.google.com) and there is a form that will help you check both your answers and your evidence for each Event presented!

Here's another set of flashcards to practice! |
Evidence of Production of a Gas• Bubbles
• Fizzing • Smoke • Production of an Odor |
Unexpected Color Change• NOT dissolving something
• NOT food coloring • Rusting • Tarnishing • Adding two clear liquids and getting a yellow substance |
Formation of a Precipitate• Liquid + Liquid = Solid
(The yellow in the video below is a solid!) |
Unexpected Change in Energy• Temperature increases (without adding heat)
• Temperature decreases (without cooling it) • Light is produced |
