First-year teacher, 9th grade bio - 40 kids per class. My goal on day 1, other than to communicate certain class rules and expectations, is to get kids intruiged about biological science. I have 3 mini-activities planned, each designed to faciliate a specific learning objective. My question to you is whether you think I have realistically alloted enough time for each of these activities. Objective 1: Students recognize that science begins by asking questions, and that biologists ask questions about living things. I will show the class images of a few strange and cool-looking animals, such as a two-headed snake or a star-nosed mole. After viewing an image, students will pair up for two minutes to discuss possible questions a biologist would ask about the animal (a Think, Pair, Share activity, 10 minutes). Objective 2: Students know the difference between qualitative and quantitative data. I will pass out bags of moldy bread, and ask students to verbally share observations about the mold. I will divide the board in half (qualitative data vs. quantitative data) and ask the class where (on which side) each observation belongs (10 minutes). Objective 3: Students understand that a hypothesis is a possible explanation for a set of observations. I will describe a situation where 50 people got sick after attending a popular sporting event. I will then asking students to come up with some possible hypotheses to explain the mystery illness, and perhaps brainstorm ways that the hypothesis could be tested (10 minutes). I figure this gives me about 15 minutes to introduce myself and review rules and procedures at the start of class, plus 5 minutes transition/settling down time (50 minutes total.) Am I off base with time allotment here? It has never been my strong point.
