Vital Signs @ Belle Valley & IMSA – Thursday: The Blood Part 1

Vital Signs @ Belle Valley & IMSA – Thursday: The Blood Part 1

Today, our scientists delved into the study of blood type and the genetics that help determine it. Students first discovered the physical basis behind the ABO blood type group, analyzing different antigens. In the lab, they attempted to determine the blood type of different samples by creating antibody reactions.

The analysts-in-training also learned the basics of Mendelian genetics, discovering how blood type traits are inherited and why some are dominant over others.

Ask your student:

How many total possibilities are there for blood type? (there are 8 including both genes: A+/-, B+/-, AB+/-, and O+/-)

What is one method to predict the blood type of the offspring when you know that of the parents? (use a Punnett square)

Extreme Math & Science – Thursday: Modeling

Extreme Math & Science – Thursday: Modeling

Today in Extreme Math and Science, students created their own model from scratch on VenSim. They came up with their own ideas for their model and then created it. After it was created they ran different checks on it and then saw how the unknown factors affected the model.

Ask your students: How did your group create your model?

Engineering Explorations @ Aurora – Thursday: Solar Cars

Engineering Explorations @ Aurora – Thursday: Solar Cars

Today, our engineers explored how their knowledge could be applied to the real world, by building solar cars! In this first part of a two part lesson, the students tested how different types of light effected their motors. Then, they got the wheel rolling by creating the body of their solar cars. Tomorrow they’ll complete their cars and put them to the test!

Ask your student: What is a solar cell? (It’s the “battery” of the car; it converts light into energy)

Fun fact:  The first solar cars were built in the 1950’s.

CSImsa @ Belle Valley – Thursday: Drops to DNA Part 1

CSImsa @ Belle Valley – Thursday: Drops to DNA Part 1

Today our CSI technicians began what will be a two day process to extract DNA from a broken vase found at the crime scene. In order to prepare themselves to discover what should be the most convincing piece of evidence, students learned about the extraction process by using their own DNA!

After their training, investigators are ready to process the last piece of evidence tomorrow!

Ask your student:

What was one substance you used in the extraction of your own DNA? (Gatorade, soap, alcohol)

BioSleuths @ Belle Valley – Thursday: Grasshopper External Dissection

BioSleuths @ Belle Valley – Thursday: Grasshopper External Dissection

Today, our young anatomy investigators set their sights on grasshoppers! Students mainly focused on the grasshopper’s appendages and other features that were easily visible, observing how the structure of each part might enable it to function most efficiently. Our biosleuths even got the chance to identify some correct or incorrect features on famous cartoon insects like Jiminy Cricket!

Students will continue their grasshopper dissections tomorrow by exploring the internal features of the same insects they worked on today.

Ask your student:

What are the three body segments of the grasshopper called? (head, thorax, and abdomen)

Why are the grasshopper’s back legs different from its front legs? (they need to be bigger for jumping)
