Vital Signs Aurora: Chicken Wing Thing

Vital Signs Aurora: Chicken Wing Thing

On the first day of a jam-packed week, students delved into anatomy by learning the basics of dissection! Our budding scientists explored the structures of a chicken wing, discovering characteristics that are shared with the human arm. As they examined deeper levels of complexity during their dissection, they observed the interactions between systems and structures that allow the wing to function.

Students also learned how to preserve the bones of the chicken wing in order to use them in one of Friday’s lessons!

Ask your student:

What is the difference between the flexor and extensor muscles? (They work together to move the arm/wing, flexor curls the limb, extensor extends it)

What are the two bones of the lower arm/wing? (radius and ulna)

BioSleuths Aurora: Soil Life

BioSleuths Aurora: Soil Life

Whether you can see them or not there are many things living in the soil. This is one of the concepts your student learned today.  Students set up two experiments today to learn not only about where life comes from but also what kinds of organisms live in the soil. Students worked in groups to prepare their first experiment. They placed pieces of chicken in cans with different coverings; they will come back to these cans later in the week to observe what is new. After this experiment they collected soil samples to learn about all the living things inside of it. Many of the students found worms or other critters while they were on this mission.

These curious biosleuths shined light directly over the Burlese-Tullgren funnel to help them understand what organisms live in the ground.  “I think I’m going to find more worms in my soil.” hypothesized one of the sleuths.

 

Ask your student:

How did the light help you find organisms in the Burlese-Tullgren funnel set up? (organisms will tend to move away from the light/heat source, which is downward into the alcohol).
