Each year eighth graders at RCLS design a science fair project and complete experiments at home. Nico chose to do an experiment about which solution (lemon juice, dish soap, coke, water, vinegar, etc) would take the tarnish off US coins. Here Nico is taking before pictures of his coins before dropping them into each solution. The coins will be in the solution for 24 hours and then he will remove them, wipe them off and take more photos.

Ready to begin:
Nico watching the beginning of his experiment.
After he wrote the time the experiment started and the end time he realized he wrote it is German! Oh!
With five kids and two adults we needed a closed trailer to transport bikes.
We took Nico to Douglas Trail for an autumn inspired bike ride.
After 8 miles of biking we stopped for a picnic.
Then we headed back.
