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.)

Travel Activity

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. 1. Your road trip must consist of 4 legs; the first leg beginning in Sacramento.
  2. 2. At least two of the legs must cover a minimum of 250 miles (North/South or East/West).
  3. 3. Your road trip must take you into Nevada at least once.
  4. 4. Clearly mark your map with your chosen route.
  5. 5. Average the speed limits for each leg to calculate average speed.
  6. 6. Use the average speed and the distance traveled to calculate the time.
  7. 7. Show all your work.
  8. 8. Round all numbers to the nearest tenth place.
  9. 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.

  1. Please convert or use metric units.

    Thank you

  2. Great idea! (PS. Fix the time units in your example!)

  3. Sounds great and meaningful. I will try to use it when we study Motion and Speed.

    Thank you. Have a great year!

  4. I love this concept! I am reworking the lesson right now to suit my location and needs, such as adding a requirement that each leg have non-freeway miles included (to prevent the slackers from slacking!)

    My only real concern is this statement, “Average the speed limits for each leg to calculate average speed.” We have to be careful with this at the 8th grade level, because depending on exactly what is being done here, this could promote common misconceptions. In my class, almost every students thinks that the average speed is an average of all the speeds. Unless we are using calculus, this is not true. For example, if I travel 100km at 100 km/hr and 100 km at 50km/hr, that is not an average speed of 75km/hr, but 67km/hr. I would never have my students average a series of speeds for any reason.

  5. Thanks for the tip about average speed. I will make the edit so I don’t contribute to misconceptions. As far as converting to metric… I do use metric regularly with my students, but for this activity I do think miles and miles per hour are appropriate. They are using a California State map, mileage and speeds in California are not typically shown in metric.
    I believe it is more true to the students’ experience to keep it as is. Certainly those who would like to make the conversions will do so.

Accelerating into NGSS – A Statewide Rollout Series Now Accepting Registrations

Posted: Friday, January 19th, 2018

Are you feeling behind on the implementation of NGSS? Then Accelerating into NGSS – the Statewide Rollout event – is right for you!

If you have not experienced Phases 1-4 of the Statewide Rollout, or are feeling behind with the implementation of NGSS, the Accelerating Into NGSS Statewide Rollout will provide you with the greatest hits from Phases 1-4!

Accelerating Into NGSS Statewide Rollout is a two-day training geared toward grade K-12 academic coaches, administrators, curriculum leads, and teacher leaders. Check-in for the two-day rollout begins at 7:30 a.m., followed by a continental breakfast. Sessions run from 8:00 a.m. to 4:15 p.m. on Day One and from 8:00 a.m. to 3:30 p.m. on Day Two.

Cost of training is $250 per attendee. Fee includes all materials, continental breakfast, and lunch on both days. It is recommended that districts send teams of four to six, which include at least one administrator. Payment can be made by check or credit card. If paying by check, registration is NOT complete until payment has been received. All payments must be received prior to the Rollout location date you are attending. Paying by credit card secures your seat at time of registration. No purchase orders accepted. No participant cancellation refunds.

by Holly Steele

The California Science Teachers Association’s mission is to promote high-quality science education, and one of the best practice’s we use to fulfill that mission is through the use of our Facebook group pages. CSTA hosts several closed and moderated Facebook group pages for specific grade levels, (Elementary, Middle, and High School), pages for district coaches and science education faculty, and the official CSTA Facebook page. These pages serve as an online resource for teachers and coaches to exchange teaching methods, materials, staying update on science events in California and asking questions. CSTA is happy to announce the creation of a 6th group page called, California Administrators Supporting Science. Learn More…

Find Your Reason to Engage

Posted: Monday, January 15th, 2018

I was recently reflecting on events in the news and remembered that several years ago, National Public Radio had a story about a man named Stéphane Hessel, a World War II French resistance fighter, Nazi concentration camp survivor, and contributor to the United Nation’s Universal Declaration of Human Rights. The story focused on a book he had published, Time for Outrage (2010).

In it, Hessel makes the argument that the worst attitude is indifference:

“Who is in charge; who are the decision makers? It’s not always easy to discern. We’re not dealing with a small elite anymore, whose actions we can clearly identify. We are dealing with a vast, interdependent world that is interconnected in unprecedented ways. But there are unbearable things all around us. You have to look for them; search carefully. Open your eyes and you will see. This is what I tell young people: If you spend a little time searching, you will find your reasons to engage. The worst attitude is indifference. ‘There’s nothing I can do; I get by’ – adopting this mindset will deprive you of one of the fundamental qualities of being human: outrage.  Our capacity for protest is indispensable, as is our freedom to engage.”

His words make me take pause when I think of the status of science in the United States. A general “mistrust” of science is increasingly pervasive, as outlined in a New Yorker article from the summer of 2016. Learn More…
