With the teacher's assistance, students complete the lab worksheet by offering their observations and conclusions. Each student first writes a hypothesis on the lab sheets. The teacher then inserts the sharp point of a straight pin into the large end of an inflated balloon. If done correctly, the balloon will not pop. A student volunteers to insert the pin into the side of the balloon, which should cause it to pop.
Students independently write their observations and conclusions.
Explain the difference between observations and conclusions. They must find 3 things to share with the class the following day. Rewrite the information found on the web. Include the specific website on which the information was found. Explain how it relates to the classroom activities.
