Our next unit after density was fossils. In this unit, we did experiments based on the placing of fossils. We did a booklet on fossils and their era. It was a masterpiece. The booklet taught me a lot on the different era and what animals existed during the era's. We also went to the White Desert as a exploration trip to investigate and find some fossils. We did not succeed, but we sure did see a lot of clean and mysterious sites.
