Recently, our 6th graders dove into the Engineering Design Process. Each student individually took on the challenge of designing and building an insulating device that can hold 200mL of hot water and trap the most heat for 20 minutes. To prepare for this challenge, the students studied the transfer of heat, differentiated between insulators and conductors, and researched good household materials to use as insulators.
Once the research and designs were created, it was time to build their devices! Each student built their own unique design and tested it. Once they tested their device the 6th graders had the opportunity to analyze their trial one data, reflect on the effectiveness of their design, and modify their thermos for a second trial!
To reflect on the whole Engineering Design Process from start to finish, the students wrote a personal narrative to add to their middle school writing portfolio. They published their narrative on Flipgrid and had the opportunity to encourage one another by commenting on each other’s videos.
Whew! Our 6th graders worked hard to sharpen their 21st Century skills as they thought critically, used creativity to design and build their thermos, collaborated with others, and communicated their experiences with the engineering design process!

Have you ever wondered what might happen to a bird species over 20,000 years? The 8th graders explored this idea in science while studying natural selection . First, students learned the concepts of existence, diversity, extinction, anatomy, genetic variations, mutations, survival, reproduction, traits, predominance, suppression, adaptations, and natural selection. Once they were confident in their understanding, they chose a bird specie and researched it. From this foundation, creativity was unleashed, synthesis took place, and depth of understanding was showcased.
Students had to envision realistic changes and adaptations that could take place with their bird over 20,000 years to enable it to survive and thrive. Students drew 2 dimensional drawings of the way their bird would look in the future along with the habitat it would live in. They also used the 3D CAD design tool Tinkercad to design a functional beak. Once the beaks were printed, students video recorded the testing process of their beak trying to pick up the intended food source. Students created the background production of their project using a green screen app by Do Ink. They used their two 2D drawings along with the video of their beak test to create the three layer background.
When students were satisfied with the three layers of their background production, they pulled the footage into iMovie. Here they synthesized the story of their bird specie from the present to the year 22,020 using realistic and deep explanations rich in factual scientific vocabulary. This science project gave the 8th graders the opportunity to explore an interest (each chose their own bird specie) to gain knowledge, understanding, application, analysis, evaluation and creativity of the science behind natural selection and adaptations.
