Hello there, I am new to this forum and am looking for a little advice. I have to conduct a 7-minute lesson plan in front of a high school biology class as part of a selection process for a teacher residency program. I seem to be stumped on finding an activity that will; a. be within the 7-minute time frame b. show evidence of student learning c. designs lesson to incorporate student interaction d. encourages all students to participate I've been looking at various lesson planning / activity books for science teachers and websites with lesson plan / activity ideas, but they are all at least 20 minutes in length or more. I was trying to think of food web activities, for example; ask them what they ate for breakfast/lunch/dinner, then break down the food products into individual ingredients on the board and categorize them into producers, consumers, etc, and then break that down even further and ask them questions. But, I am not 100% confident in this idea. I would greatly appreciate any advice!
