If you don't already have it, download the Voicethread app. It should be free. Using the voicethread app record information about the second part of the champion racer lab. As your image use your data table. Take a picture/screen shot of your data table. When you open voicethread, hit create, then hit the green plus sign. Add your data table. Hit comment and then the microphone symbol to begin your recording. When you are done you need to email the recording to your school email.
What variable you tested in the new experiment (or trials 9,10,11,12). Share your new question. Share what happened and why you think it happened. What did you learn? How does this experiment compare to your control?
Now your goal is to post your voice thread to your website. Post it under science experiments (which you may need to create as a subpage of science).
