Describing rocks
working as a team select a rock from a pile and write down as many words or sentences that describe your rock.

After you have written the description put it back in the pile of similar rocks and the next group trys to find it (WOULD probably need older grade buddy to do the writing and reading and younger child to listen and find)

Everyone brings in rocks and maybe someone in the community is a "rock hound" and invite them. Label the rocks and read Magic School Bus Inside the Earth

What is alike and different
try different things like water

Using your collection line them up by attributes.. first with 1 attribute the same then on and on.

sort and classify venn diagram

Make stalagmites and stalactites using baking soda and VERY hot water (BE CAREFUL)
stir in until no more will dissolve. Pour an equal amount of the solution into each cup, and arrange the cups on the tray so that the saucer fits between them and is touching both of the cups. Fold the string in half and place an equal amount into each cup and let the string hang between the cups drape over the saucer. Cover the cups loosely with the foil or plastic wrap and set aside for a few days (capillary action moves the baking soda through the string until it reaches the bottom of the curve. Gravity forces the solution out of the string a drop at a time. Baking soda builds up and forms a desposit.

Create a list of facts your kids know about rocks and what makes up the earth
vocabulary

objectives where do rocks come from what are they made of what type are there how are sedimentary rocks formed igneous metamorphic how can they help us learn what went on long ago how do we use rocks everyday

Experiment
nectarine or freestone peach knife paper towels

cut the fruit so it can be pulled apart leaving the seed Refer to the drawings in MSB inside the earth so they can see the likeness examine the skin, flesh, and see. relate to earth core, crust etc.

Discuss Volcano's

MSB Inside the earth Rocks and Minerals by Illa Podendorf

If you found a new rock that had never been discovered how would you name it?

Make rocky creature using pebbles glue together for creatures.. make a pet rock etc.
make a crystal garden in a dish Line bottom of a aluminum pie pan with briquets. Mix 1/4 c of ammonia, salt and bluing. Pour it evenly over the briquets. sprinkle food coloring over each briquet. crystals in a few days make a volcano grow salt or sugar crystals

Peanut butter and jelly geology
sedimentary rock form in layers. bread, butter, jelly, peanut butter, knife & napkins
make the sand. layer by layer as the kids watch. describe as a sedimentary rock layers
being laid down one layer at a time over many millions of years one after another. You now have a 5 layered model. it it gets stale and hard it will show how sedimentary harden into rock
Bend and fold the sand. to show how layers can be folded after they form. cut the sand. into quarters and use t
2 of the pieces side by side to show how earth moves along crack(fault) to make mountains and earthquakes the knife cut is the fault.
