The 5/6th graders have been studying ecosystems in science. Part of their lessons involved learning about food chains and food webs within each ecosystem. Today they got to see up close and personal what common barn owls eat by dissecting owl pellets. Owl pellets are the undigested remains of an owls diet. Owls swallow large portions of their food whole. The meat from the prey they consume slowly separates during digestion. The softer meaty parts separate from the harder unusable parts. The owl keeps the parts it needs and then regurgitates the extra materials like bones, feathers, and fur.

The roller coasters are starting to really take shape this week. The main structures are almost complete, and by next week we should see some tracks going in. The students are really excited to get to the next step in the building process, but they also know how important a strong and sturdy structure is to the success of their project.
In class today the 7/8th grade built models of DNA using licorice and colored marshmallows. The licorice represents the sugar-phosphate molecules and the marshmallows represent the 4 different nitrogen bases. The class had to build their DNA strand by remembering to always pair Adenine with Thymine and Guanine with Cytosine.
January marks the beginning of a long term STEM project involving roller coasters. We started off the month in the classroom looking at different roller coaster videos, learning about kinetic and potential energy, recording roller coaster data involving speed, angles, drop heights, and g-force; and calculating mean, median, and modes of different data sets. On Thursday we started constructing the framework of our own paper roller coasters. Here is a look at our first day of construction. Check back soon for more updates on our progress!
