Homework:
 - Review observations and inferences. Think about the inferences you can make from looking at dinosaur footprints (or any other trace fossil). Here were the observations. You should have an inference for each of these:
Qualitative:
1. Footprints have sharp toes.
2. Footprints have rounded toes.
3. The sets footprints are not the same.
4. The footprints intersect.
5. A set of footprints changes directions.
6. A set of footprints had shadows within it; the others do not.
7. A set of footprints leaves where the two sets intersected, the others do not.
Quantitative:
1. Footprints B have a stride 3-4mm (scaled) larger than footprints A.
2. Footprints B measure 9mm (scaled) in length, footprints A measure 4mm.
3. Footprints B stride increased from 3-4mm to 12-15mm. Footprints A remained unchanged.

Today in class we:
 - Received our unit four tests back
 - Finished our footprint observations and practiced making inferences
