Cup of Tea

Have you ever felt like your time is split between too many subject areas in your classroom and you’re torn on how to teach all of the content? As a 5th grade teacher in a self contained classroom, I have always struggled with integrating curriculum in my classroom instruction. Through my participation with the Next Generation of Science Standards (NGSS) Early Implementation team in Galt, I have learned how to take the science and engineering practices (SEP) and incorporate them into the other curricular areas using simple modifications to my instruction.
Instead of looking at science and engineering practices as only part of the three-dimensional learning of NGSS, I try to think of ways to incorporate them into other content areas, so I can create bridges for learning. For instance, inspired by the Boston Tea Party after my students studied the American Revolution, students engineered crates to hold tea.
Engineering Task: Design a crate that can hold a tea bag submerged into a tub of water without leaking.
- Design Phase: Students design and create a crate that will keep their tea bag dry for the longest period of time in a tub of cold water.
- Building Phase: Students worked in groups of 3. Each group was given 16 popsicle sticks, a 2 inch by 2 inch square of wax paper, one 6 inch strip of masking tape, 12 inch piece of yarn, 1 tea bag, and a tub of water. They had 20 minutes to complete this phase.
- Test Phase: Student groups tested their designs by submerging their tea crates in tubs of cold water. Leakage was determined by the color of the water around the crate. When the water turned dark, the timer would stop. One group’s crate went an entire 24 hours without leakage, so the class studied their design and tried to recreate their crates.
- Redesign and Re-build Phase: Students had 30 minutes to redesign and rebuild their crates using the same materials as before.
- Re-Test Phase: Students were more successful with their crates this time around and they didn’t leak as fast in the re-test phase.
During the engineering process, I noticed collaborative conversations and problem solving. Some students tried raft and pontoon designs, but those did not withstand the challenge while others tried a fully enclosed crate that was successful. The students who were the most successful completely encased their tea bag in the wax paper while binding it with yarn and then wrapping the Popsicle sticks around the bundle.
Thinking outside the box is the key to lessening the load in the classroom and incorporating multiple content areas; no pun intended. The three-dimensional learning called for in NGSS provides many opportunities to integrate in a cross curricular manner and provides rich learning experiences for students.

In June 2016 California submitted a waiver application to discontinue using the old CST (based on 1998 standards) and conduct two years of pilot and field tests (in spring 2017 and 2018, respectively) of the new science assessment designed to support our state’s current science standards (California Next Generation Science Standards (CA-NGSS) adopted in 2013). The waiver was requested because no student scores will be provided as a part of the pilot and field tests. The CDE received a response from the U.S. Department of Education (ED) on September 30, 2016, which provides the CDE the opportunity to resubmit a revised waiver request within 60 days. The CDE will be revising the waiver request and resubmitting as ED suggested.
At its October 2016 North/South Assessment meetings CDE confirmed that there will be no administration of the old CST in the spring of 2017. (An archive of the meeting is available at http://www.cde.ca.gov/ta/tg/ai/infomeeting.asp.) Learn More…

1) To celebrate the 100th anniversary of the National Park Service, Google has put together a collection of virtual tours combining 360-degree video, panoramic photos and expert narration. It’s called “The Hidden Worlds of the National Parks” and is accessible right from the browser. You can choose from one of five different locales, including the Kenai Fjords in Alaska and Bryce Canyon in Utah, and get a guided “tour” from a local park ranger. Each one has a few virtual vistas to explore, with documentary-style voiceovers and extra media hidden behind clickable thumbnails. Ideas are included for use in classrooms. https://www.engadget.com/2016/08/25/google-offers-360-degree-tours-of-us-national-parks/. Learn More…

CSTA is pleased to announce the winners of the 2016 CSTA Awards for Distinguished Contributions, Margaret Nicholson Distinguished Service Award, 2014 and 2015 PAEMST-Science recipients from California, and the 2016 California PAEMST Finalists. The following individuals and organizations will be honored during the 2016 California Science Education Conference on October 21- 23 in Palm Springs. This year’s group of awardees are truly outstanding. Please join us in congratulating them!
Margaret Nicholson Distinguished Service Award
The Margaret Nicholson Distinguished Service Award honors an individual who has made a significant contribution to science education in the state and who, through years of leadership and service, has truly made a positive impact on the quality of science teaching. This year’s recipient is John Keller, Ph.D. Dr. Keller is Associate Professor, Cal Poly San Luis Obispo and Co-Director, Center for Engineering, Science, and Mathematics Education, Cal Poly San Luis Obispo. In her letter of recommendation, SDSU science education faculty and former CSTA board member Donna Ross wrote: “He brings people together who share the desire to make a difference in the development and implementation of programs for science teaching. Examples of these projects include the Math and Science Teaching Initiative (MSTI), Noyce Scholars Program, Western Regional Noyce Initiative, and the Science Teacher and Researcher (STAR) program.” Through his work, he has had a dramatic impact on science teacher education, both preservice and in-service, in California, the region, and the country. He developed and implemented the STEM Teacher and Researcher Program which aims to produce excellent K-12 STEM teachers by providing aspiring teachers with opportunities to do authentic research while helping them translate their research experience into classroom practice. SFSU faculty member Larry Horvath said it best in his letter:“John Keller exemplifies the best aspects of a scientist, science educator, and mentor. His contributions to science education in the state of California are varied, significant, and I am sure will continue well into the future.” Learn More…

NGSS is a big shift. Teachers need to learn new content, figure out how this whole engineering thing relates to science, and develop new unit and lesson plans. How could NGSS possibly make life easier?
The idea that NGSS could make our lives easier came to me during the California State NGSS Rollout #1 Classroom Example lesson on chromatography. I have since done this lesson with high school chemistry students and it made me think back to having my own students do chromatography. I spent lots of time preparing to make sure the experiment went well and achieved the “correct” result. I pre-prepared the solutions and organized and prepped the materials. I re-wrote and re-wrote again the procedure so there was no way a kid could get it wrong. I spent 20 minutes before the lab modeling all of the steps in class, so there was no way to do it wrong. Except that it turns out there were many. Learn More…

Our evening twilight chart for September, depicting the sky about 40 minutes after sunset from SoCal, shows brilliant Venus remaining low, creeping from W to WSW and gaining a little altitude as the month progresses. Its close encounter within 2.5° N of Spica on Sept. 18 is best seen with binoculars to catch the star low in bright twilight. The brightest stars in the evening sky are golden Arcturus descending in the west, and blue-white Vega passing just north of overhead. Look for Altair and Deneb completing the Summer Triangle with Vega. The triangle of Mars-Saturn-Antares expands as Mars seems to hold nearly stationary in SSW as the month progresses, while Saturn and Antares slink off to the SW. Learn More…
