Kalama Intermediate's 8th grade Earth science OPIHI field trip (teacher Diane Banks) April 20th 2007


Straightening out the transect line


Ready for a great field trip!


Look how good the look boxes work!


The groups are spread out in a circular radiating pattern on the tip of one of the rocky spits from Waipuilani Beach


Holding down the quadrat with your feet prevents it from floating away


Different group members perform different tasks, such as writing and holding the ID cards


Sea urchin (Echinothrix calamaris)


Getting up close and personal with the intertidal means turning over rocks to find creatures hiding beneath


Using a pencil helps when doing point-intercepts to determine what is directly under the intercept


Groups radiate out from the tip of the first spit from Waipuilani Beach as seen here


Transects were 20m long and started about 3m in from shore


Getting a closer look at an organism


Even at sites where there initially does not appear to be many creatures - turning over rocks you can always find a lot of things!


This big rock is sure to have a lot of invertebrates associated underneath it


Look boxes are especially helpful when the water is a little deeper and ripples make it hard to see underwater


Examining and organism closely helps to identify it correctly


Waipuilani Beach's spits are revealed at low tide and are made of coral rubble


If an organism is not on the ID cards, we have to consult books!


Getting close to the transect lets you see things more accurately


The students show their teacher (Diane Banks) something exciting they just found


Even with all the hotel nearby, there are a lot of organisms at this beach!


Still hard at work


Brittle stars (Ophiocoma erinaceus) are common in Hawaii's intertidal and are fun to hold


We found a scorpion fish! (And very very carefully maneuvered it into this container - they are poisonous!)


Looking up the identify of our scorpion fish


Look boxes make good temporary holding tanks for organisms you want to show off - like our scorpion fish!
