5th grade students will learn about physical and chemical changes as they perform this experiment. They will need baking soda, vinegar, 2 clear cups, a spoon and thermometer, a stopwatch or timer and safety goggles. Teachers notes will provide some guidance for teachers when it comes to the outcome and answers.

What to do:
1. Put on your safety goggles.
2. Place a spoonful of baking soda into one of the clear cups.
3. Pour an equal amount of vinegar into the other clear cup.
4. Measure the temperature of both cups using the thermometer and record it in a table.
5. Observe the two cups and record your observations in a table.
6. Slowly pour the vinegar into the cup with baking soda and immediately start the stopwatch or timer.
7. Observe the mixture and record your observations in a table.
8. Measure the temperature of the mixture using the thermometer and record it in a table.
9. Repeat steps 4-8, but this time, place the vinegar in the cup with baking soda.

What happened to the baking soda and vinegar when they were combined?
• Was there a change in temperature? If so, what happened?
• Did the mixture change in color or texture? If so, how?
• Was this a physical or chemical change? Explain your answer
