Georgia 4-H at Camp Jekyll: Environmental Education

Student Journals

Many schools choose to have their students complete journals while they are here. You are welcome to use the journal questions we have provided. If you choose to make your own, please make sure we get a copy well before your visit so we can make sure we cover all of your questions. You might also consider scheduling journals as one of your teacher led activities (day or evening) as a structured time for students to reflect.
