are welcome to use these ideas in your classroom, within your science
department, within your school district, or to distribute to any
teacher who may find these lessons useful. I only ask that:
1. You cannot sell these lessons or make a profit on them in any way.
2. You cite the lessons original source, and do not white-out the
copyright footer on the pdf files
3. Do not copy and paste lessons onto your website. A link to the
original is to be used.
4. Do not claim these lessons as your own work.

Spot and Middle School Science. Thanks, teachers!

contain exercises covering this topic also. All mine are copyrighted

A good way to
of rock sequencing is to present each step with a separate sketch. We
usually just give students the finished product and many students have
trouble with seeing how the finished diagram came to be. Here are a
couple of good sequencing games. I give each team the four sketches
along with 4 sticky notes. They have to put the sketches in order and
put a sticky label with each sketch explaining what cause the change in
each sketch. Click here for the first
game and click
here for the second game.
These are in worksheet form. Run off and cut out for the game. I use as
many teams as I need to put 4 or 5 in a team--often 5 or 6 teams, each
identified by a different color.

I don't use this too often anymore. Don't see the need for quiet
seatwork when we could be doing something more lasting,
like a game or
