California Road Trip – An Activity for 8th Grade Science
Posted: Thursday, September 1st, 2011
by Lisa Hegdahl
California Science Content Standard 1c for 8th Grade states: “Students know how to solve problems involving distance, time, and average speed.” After years of teaching the basic calculations, and tired of word problems, I designed an activity that gives students independent practice while at the same time providing them with an engaging activity. There is probably a faster way to do what I did using current technology, but reading the steps I took will guide you to create the handouts by whatever method you would like. On the old Automobile Association of America California road map, there is a smaller map that shows just the main roads in California (and part of Nevada). Between the cities, which are designated by large dots, two numbers are written on the roads – one for the distance and one for the estimated driving time. I photo-copied and enlarged the mileage map so it fit an 8.5” x 11” sheet of paper and I used white out to cover up the estimated driving times replacing them with average driving speeds.
I decided on some guidelines for the ‘road trip’ and made a grid for students to keep a record of their destinations and travel calculations. For guided practice, my students and I complete one leg of the trip together. We all start in Sacramento and ‘drive’ to Bakersfield. Students look at their maps and read me the numbers for our calculations. Below are the instructions showing the part of the chart I fill in with them. (Note: on my example in my class, I show the calculations in the boxes. I have left them out here to save space.)
Instructions: You are taking a road trip!!! You may travel anywhere indicated on the California/Nevada map as long as you follow the simple guidelines that are listed below.
- 1. Your road trip must consist of 4 legs; the first leg beginning in Sacramento.
- 2. At least two of the legs must cover a minimum of 250 miles (North/South or East/West).
- 3. Your road trip must take you into Nevada at least once.
- 4. Clearly mark your map with your chosen route.
- 5. Average the speed limits for each leg to calculate average speed.
- 6. Use the average speed and the distance traveled to calculate the time.
- 7. Show all your work.
- 8. Round all numbers to the nearest tenth place.
- 9. Clearly mark your map with each leg and attach it to your worksheet.
The example is left on the white board while students work so they can refer to it during independent practice. Students trace the route they take on the map, cut it out along with the worksheet, paste them onto construction paper, and post them in the room.
Student engagement is high during this activity. Conversations about where they are ‘driving’ fill the room as they read their maps and work with the numbers to finish their calculations.
I’m confident that you and your students will also find it enjoyable and worthwhile.

The California Science Teachers Association (CSTA) stands with our science and science education colleagues in endorsing the March For Science and its associated activities.
The decision by the CSTA Board of Directors to support the March for Science was based on the understanding that this is an opportunity to advocate for our mission of high quality science education for all and to advance the idea that science has application to everyday life, is a vehicle for lifelong learning, and the scientific enterprise expands our knowledge of the world around us. The principles and goals of the March for Science parallel those of CSTA to assume a leadership role in solidarity with our colleagues in science and science education and create an understanding of the value of science in the greater community. CSTA believes that the integrity of the nature of science and that the work of scientists and science educators should be valued and supported. We encourage your participation to stand with us.
There are over 30 satellite marches planned for the April 22, 2017 March for Science in California (to find a march near you, click on “marches” in the upper right of the main page, select “satellite marches” and use the search feature). We encourage members who participate in the March for Science to share their involvement and promotion of science and science education. Feel free to promote CSTA on your signs and banners. For those on social media, you may share your involvement via Twitter, @cascience and our Facebook groups.

The pre-publication version of the new California Science Curriculum Framework is now available for download. This publication incorporates all the edits that were approved by the State Board of Education in November 2016 and was many months in the making. Our sincere thanks to the dozens of CSTA members were involved in its development. Our appreciation is also extended to the California Department of Education, the State Board of Education, the Instructional Quality Commission, and the Science Curriculum Framework and Evaluation Criteria Committee and their staff for their hard work and dedication to produce this document and for their commitment to the public input process. To the many writers and contributors to the Framework CSTA thanks you for your many hours of work to produce a world-class document.
For tips on how to approach this document see our article from December 2016: California Has Adopted a New Science Curriculum Framework – Now What …? If you would like to learn more about the Framework, consider participating in one of the Framework Launch events (a.k.a. Rollout #4) scheduled throughout 2017.
The final publication version (formatted for printing) will be available in July 2017. This document will not be available in printed format, only electronically.

The 2017 Award Season is now open! One of the benefits of being a CSTA member is your eligibility for awards as well as your eligibility to nominate someone for an award. CSTA offers several awards and members may nominate individuals and organizations for the Future Science Teacher Award, the prestigious Margaret Nicholson Distinguished Service Award, and the CSTA Distinguished Contributions Award (organizational award). May 9, 2017 is the deadline for nominations for these awards. CSTA believes that the importance of science education cannot be overstated. Given the essential presence of the sciences in understanding the past and planning for the future, science education remains, and will increasingly be one of the most important disciplines in education. CSTA is committed to recognizing and encouraging excellence in science teaching through the presentation of awards to science educators and organizations who have made outstanding contributions in science education in the state and who are poised to continue the momentum of providing high quality, relevant science education into the future.

If you attended an NGSS Rollout phase 1-3 or CDE workshops at CSTA’s annual conference you may recall hearing from Chris Breazeale when he was working with the CDE. Chris has relocated professionally, with his passion for science education, and is now the Executive Director at the Explorit Science Center, a hands-on exploration museum featuring interactive STEM exhibits located at the beautiful Mace Ranch, 3141 5th St. in Davis, CA. Visitors can “think it, try it, and explorit” with a variety of displays that allow visitors to “do science.” To preview the museum, or schedule a classroom visit, see www.explorit.org. Learn More…
