All school assembly - Now we are ready for the one hour all-school assembly, which is actually a dress rehearsal for Family Night. We convene as a school in the gym or cafeteria and each grade level presents their piece of the puzzle. Kindergarteners have about five minutes. They sing their song about the "big blue marble" floating in space and we look at that slide. They show us how the continents drifted apart, and we look at that slide, and they show us how to walk around like scientists either star gazing or looking into magnifying glasses or microscopes. Then they chant "It isn't what you don't know that gets you into trouble, it's what you know for sure that just isn't so."

We use the same format with every other grade level, doing in five minutes (plus about two minutes to get organized) what we did in 30 minutes of class together. Now that we have learned about what is happening, I can introduce the jagged red line which shows how much CO2 is in the atmosphere in each season, and we can talk about why it is so and the implications of continuing the line. Then we close by quickly generating a list of things that we can do to help prevent the crisis, putting them on a slide or on a white board. I get the kids excited about bringing their parents back for the evening program, and even if the family had no plans for the evening, most will come back.
