Moxlie Creek Field Trip and Request for Parent Volunteers

As I have told you in class next week we will be going on a field trip to Moxlie Creek in Watershed Park. The field trip will take place during normal school hours during 3rd and 4th period on Thursday October 16th. We will be back in time for lunch on Thursday. On that day you should be prepared for all weather possibilities, which means bring a rainjacket and shoes you don't mind getting muddy.

Also I am looking for 5-6 parents to come chaperone the field trip on Thursday. They should plan on being at NOVA at 9am and finishing at 12:30. If they can make it please ask them to email me

The Scientific Method

Don't forget you need to think up an experimental question about the NOVA garden to share with your classmates on Friday.

Also for fun check out these YouTube videos I found when I searched for "The Scientific Method".
