On September 20th, 2nd and 3rd graders from the Myron B Thompson Academy visited Chaminade University for a campus tour and a scientific laboratory experience with research scientists.
Since it’s never too early to start thinking about college, these students toured our campus by visiting the student center, checked out the library, looked in on classrooms, met professors, and explored a research laboratory.
They also spent time in our science teaching laboratory to learn about sugar by conducting experiments. They used a scale to weigh out the amount of sugar contained in a beverage to be able to see how much sugar they consume. They discovered that dissolved sugar is not easy to see, so they used hydrometers to determine the amount of dissolved sugar in various solutions. They used scales, graduated cylinders, beakers, and stir plates to see how quickly different amounts of sugar dissolves in water. Using test tubed and a vortex mixer, they discovered that there is a limit to the amount of sugar that can be dissolved in water. They also got to spend time with real live scientists and ask us all sorts of questions.
On Sunday, October 1st, I Am a Scientist and the Chaminade University of Honolulu School of Nursing will be participating in the Children and Youth Day (link) providing hands-on activities for the keiki.
This past August, our research staff and volunteers visited St. Mark Lutheran School in Kaneohe, HI. The 4th grade class compared the nutritional content of traditional Hawaiian foods to that of their modern diet. (IAS Modules Food chemistry and Hawaiian Traditional Knowledge)
Students took samples from their lunch and mashed it up with water using a mortar and pestle. Then they prepared several test tubes with a small amount of their liquid food sample. They used several chemical tests that produced a color change to detect if their food contained starch, sugar, protein and fat. For example fats will stain bright red, if there is no sugar it will turn blue, it there is sugar it will turn orange.
Traditional Hawaiian food items were also tested in the same way. The students made comparisons and determined the traditional food items were a lot healthier.
On September 7th, the I Am a Scientist program visited Aliiolani Elementary School for their Family Science Night. Students were transformed into scientists as they put on their very own lab coat. With help from Chaminade University’s Science undergraduate students, instructors, research staff & alumni, students and parents got to use real research equipment (microscopes, balances, vortex mixers, test tubes, pipets, graduated cylinders, hydrometers, and beakers) to have fun learning about sugar and nutrition.
By reading the nutrition facts label and weighing out the amount of sugar, students and parents discovered how much sugar they consume when drinking sweetened drinks.
They discovered its not easy to see dissolved sugar. Using a hydrometer they were able to tell plain water apart from sweetened liquid.
Students made a super saturated solution of sugar to understand how sugar dissolves in water. No mater how long they mixed the solution, it would not dissolve.
Students used microscopes to look at different forms of sugar.
To learn about density, they made a sugar gradient by layering different sugar solutions on top of the other. The liquid with less sugar is less dense than the others and will float on top.
“I am a Scientist” participated in the Hawaii DOE, Honolulu District STEM Exposition. Where an estimated 6,000 Elementary and Middle School students participated over 5 days at Kaimuki High School.
CUH alumni Caitlyn Tobita, Ho`oulu Scholar Hulali Kinilau, and CUH Professor Dr. Chrystie Naeole, helped students conduct experiments to understand the properties of density and why its easier to float in the ocean than in freshwater. Students also used micro pipettors to learn the density of different liquids.
Freshman Lina Tiaseu and Dr. Edna Monroe, Professor and Chief Nurse Administrator of the School of Nursing brought tools of their profession for students to use and learn about health and science.
Students were eager to use the stethoscopes, pulse oximeters and blood pressure cuffs to learn about their health and wellness.
WORKSHOP 2017_14 Hawai‘i’s Anchialine Pools and the Opae‘ula
Lori Shimoda, Environmental Studies, Chaminade University
» Hawai‘i’s anchialine pools are unique fragile environments. Make an Opae‘ula micro-habitat to learn the complexities of a sustainable ecosystem.
"I Am A Scientist STEM" is a mobile outreach program that shares our labs beyond the Chaminade University campus. Our services are FREE to Hawaii DOE schools. IAS STEM is part of a broader initiative by the Division of Natural Sciences & Mathematics at Chaminade University to encourage science awareness and education in Hawaii's public schools.
