BioSleuths @ Springfield – Monday: Soil Life

BioSleuths @ Springfield – Monday: 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 sleuthers.

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)

 

Vital Signs @ Springfield – Monday: Chicken Wing Thing

Vital Signs @ Springfield – Monday: 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)

CSImsa @ Springfield – Monday: Observation 101

CSImsa @ Springfield – Monday: Observation 101

The detectives have called in the CSI unit, and our junior forensic scientists are on the case! The investigation is well under way, with students honing their observation skills by spotting hidden objects in various pictures. They also practiced their mastery of memory and recall by seeing a series of objects and attempting to remember what was shown.

Investigators will continue to utilize their observational talent throughout the week as they attempt to solve the case!

Ask your student:

What evidence have you collected so far in the case?

How did you do in your observation and memory skills practice?

A crushed can was found at the scene of the crime, surrounded by the shards of a broken vase. What was in the vase? Why was it so important to the perpetrator?

Our C.S.IMSA Investigators are designing an experiment to replicate the evidence to determine the approximate weight and height of the broken vase. Listen to their great explanation!
