Governor Island MARINE RESERVE
VISITING RESERVES Governor Island MARINE RESERVE Governor Island Marine Reserve, with its spectacular underwater scenery, is recognised as one of the best temperate diving locations in Australia. The marine reserve includes Governor Island and all waters and other islands within a 400m diameter semi-circle from the eastern shoreline of Governor Island (refer map). The entire marine reserve is a fully protected ‘no-take’ area. Fishing and other extractive activities are prohibited. Yellow zoanthids adorn granite boulder walls in the marine reserve. These flower-like animals use their tentacles to catch tiny food particles drifting past in the current. Getting there Photo: Karen Gowlett-Holmes Governor Island lies just off Bicheno – a small fishing and resort town on Tasmania’s east coast. It is located Things to do about two and a half hours drive from either Hobart or The reserve is a popular diving location with Launceston. over 35 recognised dive sites, including: Governor Island is separated from the mainland by a The Hairy Wall – a granite cliff-face plunging to 35m, narrow stretch of water, approximately 50m wide, known with masses of sea whips as Waubs Gulch. For your safety please do not swim, The Castle – two massive granite boulders, sandwiched snorkel or dive in Waubs Gulch. It is subject to frequent together, with a swim-through lined with sea whips and boating traffic and strong currents and swells.

This includes fostering the wisest use of our land and water resources, protect- ing our fish and wildlife, preserving the environmental and cultural values of our national parks and historical places, and providing for enjoyment of life Athrough outdoor recreation. The Cultural Resource Programs of the National Park Service have respon- sibilities that include stewardship of historic buildings, museum collections, archaeological sites, cultural landscapes, oral and written histories, and ethno- graphic resources. Our mission is to identify, evaluate, and preserve the cultural resources of the park areas and to bring an understanding of these resources to the public. Congress has mandated that we preserve these resources because they are important components of our national and personal identity.

Disneynature DOLPHIN REEF Educator's Guide
Educator’s Guide Grades 2-6 n DOLPHIN REEF, Disneynature dives under the sea Ito frolic with some of the planet’s most engaging animals: dolphins. Echo is a young bottlenose dolphin who can’t quite decide if it’s time to grow up and take on new responsibilities—or give in to his silly side and just have fun. Dolphin society is tricky, and the coral reef that Echo and his family call home depends on all of its inhabitants to keep it healthy. But with humpback whales, orcas, sea turtles and cuttlefish seemingly begging for his attention, Echo has a tough time resisting all that the ocean has to offer. The Disneynature DOLPHIN REEF Educator’s Guide includes multiple standards-aligned lessons and activities targeted to grades 2 through 6. The guide introduces students to a variety of topics, including: • Animal Behavior • Biodiversity • Culture and the Arts and Natural History • Earth’s Systems • Making a Positive Difference • Habitat and Ecosystems for Wildlife Worldwide Educator’s Guide Objectives 3 Increase students’ 3 Enhance students’ viewing 3 Promote life-long 3 Empower you and your knowledge of the of the Disneynature film conservation values students to create positive amazing animals and DOLPHIN REEF and and STEAM-based skills changes for wildlife in habitats of Earth’s oceans inspire an appreciation through outdoor natural your school, community through interactive, for the wildlife and wild exploration and discovery. and world. interdisciplinary and places featured in the film. inquiry-based lessons.

WHALE HUNT: SEARCHING for WHALE FOSSILS: a SHORTER NARRATIVE More Suitable for Teacher-Directed “Whale Hunt”
WHALE HUNT: SEARCHING FOR WHALE FOSSILS: a SHORTER NARRATIVE More Suitable for Teacher-Directed “Whale Hunt” 1. We have NO fossils of modern whales earlier than about 25 million years ago (mya). However, for many years, we have been finding a number of fossils of various primitive whales (archaeocetes) between 25 and 45 million years old, and somewhat different from modern whales, e.g. with very distinctive teeth An example of these early whales would be Dorudon. Place the fossil picture strip of Dorudon at about 36 mya on your timeline (actual range about 39-36 mya); (“mya”= millions of years ago). 2. As more fossils have been discovered from the early Eocene (55 to 34 mya), we searched for a land mammal from which whales most likely evolved. The group of animals that had features like those distinctive teeth that are also found in the earliest primitive whales, was called the Mesonychids. A typical example of these animals was Pachyaena. Mesonychids also had hooves, suggesting that whales may be related to other animals with hooves, like cows, horses, deer and pigs. Place the Pachyaena strip at about the 55 mya level on your timeline. Mesonychids lived from 58-34 mya. 3. In 1983, all we had were these primitive whales and mesonychids, with a big gap in between. This year, paleontologist Philip Gingerich was searching in Eocene deposits in Pakistan, and found the skull of an amazing fossil. It had teeth like the Dorudon whale, with whale-like ear bones and other features, but it was much older (50 mya), and there were indications that it had four legs. -

ESHANESS – Inside Shetland’S Volcano
ESHANESS – inside Shetland’s volcano Explore Eshaness! The Eshaness coast is one of the walks on the Geopark Shetland Volcano Trail. We went up to Eshaness lighthouse and then took a walk around the coastline. We explored the Grind o da Navir and we had to find out how it was formed. There are magnificent cliffs and most of the land from the lighthouse to the Grind is easy to walk on. Discover Shetland’s volcano Discover coastal erosion We discovered that parts of Eshaness used to be a volcano. The rock in this At the Grind o Da Navier there is a big piece of land being eroded away by the sea. The sea is so area is igneous rock. powerful that it flings huge rocks as big as small cars over 50 metres inland. The blowhole next to the lighthouse, Kirn o Slettans, was a side cone on the There is a lot of erosion along the Eshaness coast as the sea works its way into cracks in the volcano. On windy days when the sea is rough water can shoot up out of rocks. The Hols o Scraada is a partially collapsed sea cave. the blowhole. The rock around the blowhole is made of volcanic blocks and bombs all stuck together. Erosion can make the coastline loose and crumbly but you should not take rocks from this area as it is part of our geological heritage. The cliffs are made of cooled lava called basalt. This is extrusive Conserving this heritage is an important part of being a Geopark. -

Rio Hondo Prep Arizona Geology Field Camp Geology Basics Let’s start off with a review of the major rock Sandstone whose layers are at different angles are classes. called cross-bedded sandstone. They are formed There are three different types of rocks, when winds change direction on sand dune deposits Sedimentary, Igneous and Metamorphic. Any rock which account for the different angles of the layers. that exists can be classified in one of these three categories, which are named dependent on how the rock formed. SEDIMENTARY ROCK Sedimentary rock is formed in a one of two ways, thus there are two types of Sedimentary rock, clastic and non-clastic (organic or chemical composition). Clastic Sedimentary rock is formed from bits and pieces of pre-existing rock that has been weathered (broken apart), eroded (transported away from its original location, usually by water or wind), and deposited. The loose deposits are then buried by other deposits, which compact the tiny grains together. The grains are then ‘cemented’ together to Limestone is found throughout Northern Arizona, form new rock. and is the surface rock type in most of Flagstaff and One of the common rock types in Arizona is the Grand Canyon. Sandstone. Sandstone is a clastic sedimentary rock formed when sand- sized grains (mostly quartz) eroded from other rocks are deposited in a layer which is later compressed by sediments above it. Compression is only part of the process; water from the surface which contains calcium and other elements form a cement to make the rock hard. If this Limestone is commonly formed in a clear, warm, shallow sea.
