This is a great activity to see if student understand the organization of the Periodic Table. I made it simple compared to otheres out there. I have middle school students and this is a simple overview.
The students get 'clues' to figure out where the elements go based on our 'rules'. Then the students must predict the missing element that has not been discoved and tell us about it as Mendeleev did.
This inclues a direction sheet, a clue sheet, slips to 'turn in' the missing element, the workmat (blank periodic table that I laminate) and the answers.
There is also a power point and an excell spread sheet (that can be downloaded and a Google Sheet can be created). So check out my other listings. There is a bundle discount.
