Here is a bit of background about the lesson I gave this past week. My lesson was designed for my Grade 7 class of 32 students. We have been studying several aspects of Earth, the moon, and the sun this month including seasons, tides, and phases of the moon. After watching Magnificent Desolation, narrated by Tom Hanks, students were really interested in how the moon got so bumpy. So, I designed this week's lesson on impact craters taking them from a historical perspective of what people used to think about the moon and how they once thought it was smooth until the invention of the telescope. Students looked at images of craters on the moon and discussed the relationships they could see on each.
The structured inquiry part of the lesson was all about: What affects the appearance of a crater?
Here are a few images from this week's lesson: Grade 7 scientists at work.
The students fully enjoyed this week's lesson on impact craters and you will see multiple links below which show the outcome of the lesson within their science blog posts. Students learned about the importance of following instructions the most as well as making sure that each test was done the exact same way. 
Students also learned this week that the dropping height affects the velocity of the 5 gram marble which is a direct relation to the depth of the impact site into the flour as well as the crater diameter. Students learned how to measure diameter of the crater as well as depth which was not an easy task in delicate flour.
Students also learned throughout the week that, just one investigation that is structured is just one example of how scientists can investigate a hypothesis or research question. They all came up with a variety of further inquiries they could test after this initial structured inquiry.
Below are student work samples which you can find by following the links to their blogs. You will see the data, the graphs, and their data analysis, conclusions, and further inquiries. In some you will see that they have included images from Google Earth as well.
