This is my seventh science project. It is about how molecules stick together.

Objective: Explore the way atoms stick together to make molecules.

Procedure: 

1. Get some Lego blocks, some toothpicks, some marshmallows, and some gumdrops.

Data:

How many Lego 1x2’s can you stick on a 1x2 Lego block?

1,2 blocks.

How many Lego 1x2’s can you stick on a 2x2 Lego block?

1,2,3,4 blocks

How many Lego 1x2’s can you stick on a 2x4 Lego block?

1,2,3,4,5,6,7,8 blocks

With 4 toothpicks, how many shapes can you make?

6 expected.  9 found.  Sarah got 14.

With 1 toothpick, how many shapes can you make?

1 expected.  1 found.  Sarah got 1.

With 2 toothpicks, how many shapes can you make?

1 expected. 2 found.  Sarah got 2.

With 3 toothpicks, how many shapes can you make?

9 expected. 5 found.  Sarah got 6 (but had one wrong).

Conclusion: Using models of hydrogen and oxygen bonding with up to 4 possible electron bonds, we found 3 combinations: H2O, O2, and H2O2. I thought that was neat and interesting how these molecules formed by random using rules. Without rules, the universe would go into chaos because there would be no order.
