This is the last post highlighting one of the eight Scientific and Engineering Practices and spotlighting a few lessons related to the practice. I hope that this series of posts has given you some ideas to use in your classroom. Have a great 2016-2017 school year!

print and cut apart the 8 cards for each part of the lesson
to set up the cards, use large 4×6 index cards and store in ziptop bags.
on one side of the index cards, glue on the nonsense letters
on the reverse side, glue on the fossil layers
laminate for durability
Replace the letters for each fossil layer, see my ppt for new random letters
spelling out the word “ORGANISM“ is way too easyfor students to figure out and they will not really have a chance to work on the activity with the depth of thinking and problem solving that you want them to do
be sure to stagger cards so that the order of the cards is not the same, otherwise they will flip over the cards and have the answer for part 2
This is a fantastic lesson and I have used it successfully with both 5th and 6th grade students. When introducing this lesson I use the analogy of a laundry hamper, or in most cases, the pile of dirty clothes on the floor in their bedroom. Today’s clothes would go on top of the pile, each day adding a layer of dirty clothes. The older clothes would be on the bottom of the pile, kind of like a timeline of what they wore this week. When that laundry is collected and moved to the laundry room, the layers would get disrupted. With rocks, the layers form on top of each other, and the older layers are on the bottom. We then brainstorm how those layers can be disrupted: earthquakes, tectonic plates moving, landslides, digging, etc…
For this activity, they have to figure out the pattern of how these layers are formed, and there are clues in each layer, they just need to know what to look for. For the nonsense letters, there is a pattern that connects all the layers together. Many will think it is alphabetical, but I tell them that it is not. Once they have worked on it a few minutes, I have them share their theories. Once each group has shared their theory, I give them the clue. And suddenly, the pattern is clear now that they know what to look for. Using the same strategy, they will then sequence the fossils on the reverse side of the index cards.
