Yesterday, students turned into forensic investigators to solve a classroom mystery! To determine who wrote a mysterious "evidence note," the students used paper chromatography to analyze the ink of several different black markers. While the inks all looked identical to the naked eye, chromatography allowed the students to separate the hidden pigments. They watched as water traveled up the paper, revealing that each black marker was actually made of a unique blend of blues and reds. By comparing the colorful  "fingerprints" of the suspect markers to the evidence note, students successfully cracked the case. *I didn't get a good picture of the chromatography results from the day of the lab. I attempted to recreate the results, but mine do not look as brilliant as theirs did!

Lab Highlights Foil Impressions : Students pressed their shoes into heavy-duty foil to capture clean, detailed impressions of their soles right in the classroom. Dirt Casts : They also took realistic shoe print casts in the dirt, learning how real investigators preserve outdoor evidence. Class vs. Individual Characteristics : Students analyzed various shoe prints to separate class characteristics (like brand, size, and pattern design) from unique individual characteristics (like wear marks, cuts, and specific rocks stuck in the tread). We will take the cast out Monday and learn to clean it in order to analyze the print better.

Mrs. Moss's gifted 5th-graders recently stepped into the shoes of forensic scientists for a hands-on lesson in fingerprint analysis. Using authentic, law-enforcement-grade materials, students learned the precise techniques professionals use to lift and record latent prints. Students also learned to identify the 3 main types of fingerprints: loops, whorls, and arches. Later, they used a clever macro-science trick: printing their own fingerprints onto balloons and blowing them up. This giant expansion allowed our young detectives to clearly identify and analyze the unique minutiae—like bifurcations, bridges, ends, and dots—that make every individual truly one of a kind.

Mrs. Moss's gifted 5th graders recently tackled the ultimate physics and engineering test with a high-energy Apples A-Head STEM challenge! Balancing Act & Engineering Design The Mission: Students designed and constructed custom, wearable headwear meant to securely cradle an apple. The Obstacle Course: Students had to navigate a high-stakes relay course without using their hands to stabilize the fruit. It was a fun way to combine critical thinking with active movement!

In Mrs. Moss's classroom, a surprising trend is taking over. Given the choice between free computer time and tangible, real-world puzzles, students are overwhelmingly choosing to unplug. Here is a quick look at the random, imaginative fun taking over our room: DIY Wordle: Moving the popular digital word game to the whiteboard has turned vocabulary practice into a high-energy, collaborative brain-teaser. Next-Level Snap Circuits: Instead of just following the manual, students are inventing their own complex gadgets, pushing the limits of engineering with highly imaginative new designs. Dominos: Classic dominos have become lessons in physics and persistence as students continue to create longer and more impressive domino runs. It makes this teacher happy to see students choosing hands-on learning and entertainment over computer games!

Recently, Mrs. Moss's gifted 5th graders stepped into the shoes of structural engineers for a hands-on STEM challenge. The mission? Design and build a functional, free-standing swing set using a strict budget of materials. Armed with nothing but spaghetti noodles, string, an index card, tape, and marshmallows , these bright minds had to collaborate, brainstorm, and think outside the box. They quickly discovered that turning fragile pasta into a sturdy, weight-bearing frame requires serious strategy! This is definitely one of the more difficult STEM challenges they will see this year! Check out the video at the end! Engineering in Action The Blueprint: Teams had to figure out how to balance flexibility with stability. The Pivot: When frames collapsed or spaghetti snapped, students analyzed the failure and redesigned on the fly. The Result: Students discovered how to evenly spread out weight, increase stability with the use of triangular shapes, and persevere even through repeate...
