Start class with a bang! Your students will be spreading the word around campus about how cool your science class is! This lesson allows you to set lab safety expectations and remind students what a hypothesis is and how to develop a hypothesis correctly in a totally engaging way. I use this as my first day of school activity, but could be used as a regular hypothesis / scientific method lab and lesson. The lab is exciting for students, and covers important academic topics (lab safety, hypothesis). I do this as a teacher-led demo, but would work well as a whole class activity in lab groups. Addresses many common core and Next Generation Science Standards (NGSS). Works well with interactive notebooks! Only a few simple materials required. Bundle includes: a detailed description (with photos) of how to perform the lab, student lab sheet, student worksheet (covers writing hypotheses correctly and developing experiments that test hypotheses), student example of interactive notebook entry with instructions, links to many web based videos as enrichment, additional resources, and answers and explanations to common student questions! Lesson was created for elementary and middle school students and reinforces many English language arts common core standards (such as: “Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context”). RST6-8.3, RST6-8.4
Approximately one to two class periods in length (as a point of reference, I teach a 50-minute class). Created by Mister Science

Next Generation Science Standards (NGSS) addressed in this lesson:
Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.
This standard is covered in the experiment itself. The can implodes due to the differential between the air pressure in the lab and the air pressure in the can.
Ask questions that can be investigated within the scope of the classroom, outdoor environment, and museums and other public facilities with available resources and, when appropriate, frame a hypothesis based on observations and scientific principles.
This standard is covered when students develop their own hypothesis and then answer that hypothesis by conducting the experiment.
