Guest Speaker at McKendree

Dr. Bowden, Guest Speaker at McKendree

Dr. Bowden was our guest speaker on Thursday. He spoke about assessing injuries and determining the need for an x-ray-a great follow up from yesterday‘s lesson on breaks, sprains, and strains. We can’t thank him enough!

Math@IMSA: Thursday

Today participants worked in small groups to design a scavenger hunt for their peers. Using cryptography and pattern recognition, students designed and shared their scavenger hunt across campus. The process of checking their clues, accurately modeling them and distributing them to their classmates was an exciting time for all! The hunt is on!

Ask your student:

Which pattern or cryptography pattern worked the best for you today?

What is the purpose of cryptography? Explain a time in your life when you might want to use it.

What’s Up with Water? Thursday: Sink or Float?

What’s Up with Water? Thursday: Sink or Float?

What floats and what doesn’t? What if it’s saltwater, or freshwater? Inquiry and imagination lead our “water-ful” scholars today as they set out to answer these questions. Students worked together to come up with rules on floating items in water, then tested their hypotheses using common household items like straws, corks, and bottle caps.

The students quickly began to notice the effect of density, but still had questions. One student asked, “How are boats able to stay afloat if they’re so heavy?” Their observatory skills were put to the test and they stood up to the challenge!

Vital Signs @ McKendree – Thursday: The Blood Part 1

Vital Signs @ McKendree – 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)

Math@IMSA: Wednesday

Math@IMSA: Wednesday

Today students took their knowledge of sequence and applied it to encrypted text. Learning to decrypt a Vigenere cipher was an adventure today as students worked together to understand permutations. Students manipulated materials such as cardboard, construction paper, playing chips and represented permutations as functions, cycles and graphs. Students are preparing and excited for the next step where they will design scavenger hunts for their partners using techniques from the past few days!

Ask your student:

What clues might you want to give to someone during a scavenger hunt?

Which encryption technique did they like the best and why?

What’s Up with Water? Wednesday: Solubility

What’s Up with Water? Wednesday: Solubility

Throughout the week, our newfound water enthusiasts have conducted various experiments to help them gain a better understanding of the unique properties of water. Today, they learned the difference between a physical and chemical change.

Students collected data for the heating curve of a solution and later compared their results to the heating curve of pure water. The knowledge they have accumulated has already become applicable to their exploration of solutions to global water issues.  “I never realized so many things naturally reacted with one another,” one student mentioned. We can’t wait to see what they come up with next!

Vital Signs @ McKendree – Wednesday: Banana Sutures

Vital Signs @ McKendree – Wednesday: Banana Sutures

Today, our junior medical practitioners performed their first procedure! Students practiced sutures (or “stitches”) the same way that real doctors practice: on banana peels. They primarily investigated the layered nature of the skin, and how it relates to its main function: protection. Some students were surprised to learn that our skin is actually the largest organ in our bodies!

Our fledgling scientists will continue to use their rapidly developing medical skills in the days to come!

Ask your student:

What are the names of the three layers of the skin? (epidermis, dermis, and hypodermis)

What layer of the skin is the thickest? (hypodermis – 26 mm)

Math@IMSA: Tuesday

Math@IMSA: Tuesday

Students are exploring the patterns and relationships between the numbers in the Fibonacci Sequence. Using manipulatives, cut-outs and graph paper students dove into the construction of sequences. Continuing their exploration of patterns students used street maps to explore Pascal’s Triangle. Working in small groups students explored the relationships between Fibonacci Numbers, Pascal’s Triangle and the Golden Ratio. This lead to the exploration of irrational numbers and the embedded fractions within each challenging sequence!

Ask your student:

Ask your student to summarize some of the properties they learned about today!

Ask them what was the most interesting thing they learned about a sequence of numbers?
