Kahala Elementary School 22 January 2018

On Monday, January 22, 2018, 4th graders from Kahala Elementary School were transformed into Food Chemists. They used chemistry to determine the make up of various 21st Century food items.

These young Scientists took a sample of food and made a prediction as to the amount of sugar, starch, protein and fat contained in their sample.

Samples of food, ready for the mortar and pestle!

They placed a small sample of food into their mortar, then added water using a transfer pipet and ground the food into a liquid slurry using a pestle. Using a transfer pipet, they transferred 1 milliliter of liquified food into 4 test tubes. Each tube was labeled and tested for the presence of sugar, starch, protein and fat.

Using a colorimetric assay that changes the color of the sample, the young Scientists could determine if the compound was present simply by looking at the color. They could also compare the amount of compound by comparing the intensity of the color change.

Some food items were really “gross” and “yucky” to process, while others were really “pretty”. The scientists were able to “see” the amount of fat contained in a lot of their food samples. They were able to “see” what food items contained sugar and what did not. They observed how artificial food colors affected their results. They also collaborated with classmates to compare multiple samples.

While they can not perform this test at home, this experiment encourages them to critically think about the nutritional content of the foods they eat.

Let’s think about how our modern 21st century diet compares to a traditional Hawaiian diet.

Boy Scout’s Food Chemistry, 19 January 2018

Honpa Hongwaji’s Boy Scout Troop 49 gathering goggle and lab coats, ready for a lab on food chemistry

On Friday, January 19, 2018. Boy Scouts from Honpa Hongwaji’s Troop 49 from wore lab coats, gloves and eye protection to perform a food chemistry experiment using potatoes. They examined the fat content from various forms of potatoes: plain baked, baked with butter, French fries, or chips.

Using a top loading balance Scouts weighed out 1 gram of a potato food item. The food sample was placed in a mortar. 3 milliliters of water was added to the food using a micro pipette and pipet tips. Scouts mashed the food into a liquid slurry using the mortar and pestle. The liquified sample was transferred into a test tube and a chemical indicator was added. The samples were mixed thoroughly using a vortex mixer. All samples were collected and sorted from least red to most red. The red color indicates the presence of fat, so the Scouts were able to rank the food items containing the least amount of fat to the most.

They determined French fries and chips contain a lot of fat.

Ahuimanu Elementary School 5 December 2017

On the 5th day of Christmas, my tutu gave to me, 5 scientists, 4 pounds of sugar, 3 lab stations, 2 second grade classes, and 1 school on the windward side…

On this sunny December 5th day, Chaminade Scientists and science undergraduate students took equipment and lab coats to Ahuimanu Elem.

IAS and the 2nd graders at Ahuimanu Elementary School

The “How Sweet It Is” lab allows students to experience science by weighing sugar, measuring dissolved sugar and making a super saturated solution of sugar. Using lab equipment and techniques that real scientists use on a daily basis made the students feel like real scientists. The goal of this lesson is to make students aware of how much sugar they unknowingly consume. By reading the nutrition facts label and being more aware of what is in their drink and food will allow them make healthy choices. Drink water!!

At the end of our visit we got hugs from the students, some asked if we could come back tomorrow, and a some said “This is the best day of my entire life!”

Myron B Thompson Academy 1 December 2017

On Dec 1st, 6th graders from Myron B Thompson Academy discovered that learning is fun and exciting when you do it in a newly renovated laboratory, using amazing equipment, and when your instructors are super cool Chaminade University science students.

During their “Gene Genius” module, students used colored beads to help them understand how DNA codes instructions for the diversity of life. They also extracted their own DNA, and were able to keep a sample of it in a small glass vial.

Their visit was capped off with a campus tour to see other classroom settings, the library and student center. While touring our research facility they were very excited and proud when they noticed that researchers used the same type of equipment they used in their lab activity.

Chaminade science undergraduates and Ho’oulu scholar recipients served as instructors and role models for their younger peers, demonstrating service and a path toward higher education.

IAS at Ali`iolani Elementary School 28 & 30 November 2017

On Nov 28 and 30, Scientist and students from Chaminade University visited 2nd graders at Aliiolani Elem.

Our “Germs On Me” module turned ordinary kids into “Germ Hunters”.

IAS with the 2nd graders at Ali`iolani Elementary School

Students and teachers participated in a fun activity to see how quickly a “germ” could spread from one person to the rest of the class in just a few minutes. In their experiment, a lot of kids got “infected” by the pretend germ. They discussed what to do when you get sick, and ways to prevent the spread of germs to friends and family.

Students also performed a hand washing experiment to see the effect of washing on the amount of bacteria on a their teacher’s hand. In their experiment, hand washing removed almost all the bacteria that was originally there.

The “Germ Hunters” explored their classroom to discover the living microscopic world they live in by taking samples from their environment, culturing (growing) it on an agar dish, then observing and describing what grew. They were introduced to microbiology and had a great time using microscopes.

IAS at Lunalilo Elementary 14 November

On Nov 14, the Lunalilo Elem school library was transformed into a sugar laboratory.

I Am a Scientist at Lunalilo Elementary school

Dressed in crisp white lab coats, 2nd graders participated in a sugar-science event with their parents.

  • They weighed, measured, mixed, and poured sugar.  They used top loading balances, vortex mixers, test tubes, graduated cylinders, and hydrometers to understand properties of solutions and to see just how much sugar they consume in their favorite drink.
  • They discovered a bottle of apple juice contains more sugar than a can of cola.
  • Read the nutrition facts label and make wise & healthy choices.

Girl Scout STEM Fest at the Pacific Aviation Museum

I am a scientist with the Girl Scouts of Hawaii hosted their annual Girl Scout STEM Fest at the Pacific Aviation Museum

Girl Scouts of Hawaii hosted their annual Girl Scout STEM Fest at the Pacific Aviation Museum.  STEM Fest offers a diverse opportunity for Scouts to experience scientific exploration and meet female professionals in the STEM field.

Chaminade University’s IAS program brought real scientists, Dr. Katelynn Perrault, Assistant Professor of Forensic Science, a Medicolegal Death Investigator with the Hawaii Medical Examiner’s office, and a research scientist at Chaminade University, along with their equipment, to let Scouts experience how much fun it is to learn and work in a research lab.  The equipment we use everyday help us do our job, but it’s also super cool and amazing, and we wanted the Scouts to experience that.

Scouts learnt about chemistry, density, solubility, physics, and math all while having fun.  They used top loading balances, graduated cylinders, pipettors & serological pipets, micro-pipettors & pipet tips, centrifuge tubes, vortex mixers and a centrifuge.  To experience the wonders of science using real scientific equipment with real scientists was fun and enlightening for the Scouts.

IAS at Astronaut Lacy Veach Day of Discovery, October 28, 2017

Chaminade science students shared their passion for learning with the younger generation at the Astronaut Lacy Veach Day of Discovery at Punahou School.

Ho’oulu scholars helped participants use Forensic Science techniques that they might see being used on TV or in movies. Participants made their own 10 print finger print card and learnt about finger print analysis and discovered how each finger print is unique. They also dusted and lifted latent finger prints from everyday objects to see how we leave our “prints” on everything we touch.

Environmental Studies students hosted two Ecology workshops. Participants learnt about the Ecology, Biology and Conservation of Hawaii’s Anchialine ponds. They also made a sustainable brackish habitat with ‘Opae’ula. By observing and learning from keeping their ‘Opae habitat healthy, they will continue to learn about nutrient, water, and life cycles that affect their ‘Opae.
