in matter are happening all around you. But not everything changes in the same

Choose one team member to record your team's observations on your "Data
Chart" student handout.
Start at the station designated by your teacher and follow the directions on
your "Station Instructions" handouts for each station.
When you have completed all the stations, discuss your observations as a
team. Come to an agreement about whether each change was physical or chemical
and discuss what observational evidence supports your claim. Finish filling in
the chart with your answers.
After the chart has been completed, your team will participate in a class
discussion about the types of changes that occurred at each station.
After you have completed the stations part of the activity, you will
complete the "Changes in Everyday Life" student handout individually.
