Maintaining Summer Engagement

Sunblock and beach towels, car trips that stretch out too long, and visits with friends. While summer can be a relaxing, wonderful time to unwind and rejuvenate, too often our students go far in the opposite direction, causing August/September to be a month of solid review of concepts from previous years before diving into new information. Although we cannot escape that entirely, keeping students engaged in learning new things via fun experiments throughout the summer can be a great way to keep their young brains going!
Most students have seen (or done) the “Diet Coke and Mentos” experiment (YouTube it if you haven’t seen it- it is GREAT!), and love it. Why stop there? Have students experiment with other colas, with fruit sodas, name brands against store brands, maybe peppermint vs fruit-flavored Mentos. Grocery stores regularly have 2-liter bottles of soda on sale for a dollar or less per bottle, and while Mentos are not on sale on a regular basis, Costco/Sam’s Club normally has large packs (individually wrapped in tubes of 14ish) for pretty cheap. They can measure it by height (if there is a grassy area near a brick wall for reference), by mass (measuring how much is left in the bottle), or any other way the scientists can think of!
Have some active kids who love to kick around a soccer ball? Turn it into an experiment! Deflate the ball until it is as flat as possible. Using a hand pump, pump it 10 times, and then kick it. If you happen to have an air pressure gauge that is sensitive, the students can get detailed results- otherwise, knowing the number of pumps on the hand pump will work for a summertime experiment. Yes, there is also the variable of the strength of the kick- the students can create a contraption to do the kicking for them! Every 10 pumps, measure the distance the ball travels, and see if there is a “sweet spot” for the ball to get the furthest kick.
This one is a personal favorite of mine-making bubble solution! 6 cups distilled water to 1 cup liquid dishwashing soap, and ¼ cup of light corn syrup works really well, and lasts for a long time. Dawn really does work the best… but what is the second best? Does any kind of liquid soap work? If you have young children or pets running around, be careful, as some kinds of soap can be toxic. They can make their own wands as well, using pipe cleaners, but sometimes the wands do not make good bubbles- if you can find extra bubble wands around, those may work out the best.
Making ice cream is a classic, uses a bit of science, and is a reward in itself at the end! Traditionally it was done using 2 coffee cans, but you can find balls to put the ingredients in online, and occasionally at local stores. Create some new flavors! How about root beer ice cream! Raspberry-chocolate chip? The students can run off some energy making the cans or ball move around for 20 minutes, can test the temperature of the forming ice-cream every 5 minutes, and when it is all ready to consume, have earned the reward of a dessert!
These are only a few ideas- the concept is to get the students out and into the world! Look at a bug, climb a tree, track the clouds or the stars- the sky is the limit!

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…
