We all know that writing is an important task for students. It helps their communication skills, but beyond that it also helps them to focus and develop their ideas. It's the same for teachers! Writing a lesson plan can help us to really think about our goals for the day. If we reflect on those objectives it's more likely that we're planning meaningful experiences for our students instead of just filling up the day with activities.
Planning lessons can also help us to stay organized. In the middle of a dynamic classroom, it might be easy to lose sight of our goal for the day. With a lesson plan we have a road map that can help us to get back on the right track. It can also serve as a quick last minute checklist to make sure we have all of our supplies- that way we won't be standing in front of 20 seven-year-olds who are ready to see a volcano explode and realize we forgot the vinegar at home...
There are a lot of important parts of an elementary science lesson plan, but two that stand out to me are safety considerations and assessment tools.
First, safety considerations. It's easy to take some basic safety rules for granted as adults, but for kids these ideas may not be so obvious. In the last few weeks I've seen students try to taste their glue sticks on the sly and one particularly enterprising boy try to add some holes to his shirt with a pair of scissors- and this was during a reading lesson! In science, we do a lot of hands-on work with different materials, chemicals, and even living organisms. It's really important that we think about our lessons from a safety point of view and keep reviewing safety procedures with our students.
The second piece is assessment. Maybe I planned the best science lesson in the world, but how will I know if my students really learned from it unless I plan some good assessment too? There are a lot of ways to assess kids (observing them, using a checklist, having a discussion, asking them to do a little writing, etc.). For each of our major objectives, we need to make sure we have a way to see how our students are doing. Using assessment also helps us to revamp our lessons when we need to and to see what we need to go over again tomorrow in a different way. Assessment should inform our teaching decisions.
So make a plan!
