Have room arranged to accommodate the expected number of participants.

I would suggest having no more than 2-3 participants in each group as this will cut down on unnecessary chit-chat and annoying conversations that do not pertain to the module. Kindly ask all participants to place their cell phones on vibrate or place in off position, as this is another annoying disturbance that so often occurs during professional development sessions.

The first two activities included in this module are designed to get the participants excited and engaged for the day's lesson.

The first activity will demonstrate a simple physical science model that will parallel the physics inside the popcorn kernel.

If possible place all recyclable items in recycling bins.

Monitor participants throughout the session as outlined in the lesson for students.For further information on polymers and popcorn see the credit/ references section of this module. Elaboration The microwave popcorn lesson provides us with a unique opportunity that encourages the participants to plan lessons that utilize inquiry investigations and the use of technology for learning.The participants will be able to elaborate thoughts and opinions through reflective writing.“Upon application of heat, popcorn kernels are capable of large, instant expansion transitioning from regular to highly irregular granules with high force,” the paper said.“The ability of kernels to rapidly expand may be used to power miniature jumping robots.”Think of each un-popped seed as a hunk of reserved mechanical energy, which can be unleashed and transformed into force and motion when heated.Engage conversations throughout the lesson allowing for a question and "What do you think? Have participant's share journal reflections, thoughts and opinions. " The film canister in engagement activity #1 represents the popcorn kernel's pericarp.When the Alka-Seltzer is dropped into the water, carbon dioxide gas forms.The second engagement activity will demonstrate how a physical change takes place inside the popcorn bag.Both activities can be used as either engagement activities or extension activities.The enclosed canister allows the gas pressure to increase causing the lid to "pop", whereas the popcorn kernel's pericarp acts similar to the film canister.The heat forms steam inside the kernel, the pressure builds and the kernel "pops".
