The bus will leave at 9:00 am in the morning and we will be returning around 5:00 pm. Be on time because we will be leaving promptly. Remember to bring your lunch because we won't be taking special trips into town to get food. You should also bring some warm clothing in case the weather changes.
I'll put together a small handout to orient you during the trip. Please pick up the handout after class and read it tonight. In the handout I discuss the various types of creatures we will see in the tide pools. The sketches in the handbook should help you to distinguish between the different types of creatures that live on the seashore.
This should be a fun experience and hopefully you will learn something too. As your leader I will try to make the trip a rewarding one.
