Join Curator of Paleontology, Dr. Julia McHugh, as she teaches you how to make her famous frosted sugar cookies and throws in some neat dinosaur facts! Dinosaur Cut-Out Sugar Cookies:
1 cup of sugar ¼ cup of softened butter ½ tsp. of vanilla extract 2 large eggs 1 tsp. of salt 1 tsp. of baking soda 2 ½ cups of flour In a separate bowl, sift flour, baking soda, and salt together and set aside. Cream together butter and sugar until fluffy, and sugar completely dissolves. Add eggs and vanilla to butter/sugar mixture and beat with mixer until well-blended (about 2-4 minutes). Gradually add the flour mixture, stirring well. Once entire mixture is well creamed together, divide into 2-4 “loafs” and wrap in waxed paper. Chill dough for 2-4 hours. Rolling out cookies: Cover surface with a light dusting of flour to prevent dough from sticking. Rub flour onto rolling pin and cookie cutters. Remove dough and roll “loafs” into a flat layer about ¼ inch thick (thinner for crispy cookies, thicker for doughy cookies). Use cookie cutters to cut dinosaur shapes. Peel away dough from in between shapes and add this remnant dough to the next loaf. Place cookies on non-stick or greased cookie sheet and bake at 400 degrees for 6-8 minutes, or until edges turn golden brown. Let cookies completely cool on wire rack or on parchment paper before decorating. Vanilla Butter Cream Frosting ½ cup of softened butter (not melted) 1 ½ tsp. of vanilla extract 5-6 Tbsp. of milk 4 ½ cups confectionary (powdered) sugar Cream butter using spoon or spatula until light and fluffy. Gradually add in the rest of the ingredients, beating the mixture as you add them. If too runny, add small amounts of additional sugar, or if too stiff add additional milk. Beat frosting until desired consistency. Divide into bowls and add food coloring.

In this classroom activity, students will work in groups to observe how patterns of topography, bathymetry, earthquake locations and depths, and the location of volcanoes vary across regions of the Earth. They will then use this data to predict and map the locations and types of major plate tectonic boundaries. Finally, they should begin to form an intuition about the 3D nature of these plate tectonic boundaries by sketching a cross sectional concept diagram through a convergent boundary, plotting surface topography, earthquakes' locations below the surface, the position of volcanoes at the surface, and inferring the location of the plate tectonic boundary at depth.

The Silurian coastal Maine magmatic province is characterized by commingled gabbroic and granitic magmas that have resulted in magmatic structures such as pillows and pipes that can be used to determine the kinematics of the magma chamber. On the Eastern Head of Isle Au Haut, students map and collect structural data on the contacts between commingled gabbroic and granitic/dioritic sheets and the pipes and pillows that form along the base of these. A bedrock geologic map and cross section are then made in ArcGIS showing the geometry of the magmatic sheets. We kayak out to the island to map it, but there is also a ferry there. Eastern Head is situated within Acadia National Park and, as a result, no hammers can be used.

This earth systems field lab begins with an in-class guided inquiry experience which uses Minnesota Geological Survey 3-D maps of the upper Midwest to determine where they believe glaciers may have had an influence. They will determine this by looking at landscapes and compiling their own evidence from the maps. They will also offer evidence for a hypothesis they generate which involves the direction that the glacier was traveling.

Middle School Paleontology Kit Module from Museums of the West in Grand Junction, CO. Lesson 5 on Mass Extinction. Students will learn about the causes of the "Big 5" mass extinctions in Earth's history and the effects of biodiversity over time. Lessons 1, 2, 3 and 5 can be completed without access to the Fossil Kit from Museums of Western Colorado. Lesson 4 uses fossile from the kit. District 51 personnel can request a kit to complete Lesson 4. See this URL for an overview of the module and a link to the Teacher's guide to Paleontology: https://www.museumofwesternco.com/classroom-resources/stem-lessons/

A spectacular gravel quarry near Rotterdam Junction, New York along the north shore of the Mohawk River is an ideal place to discuss deglaciation history and the development of the ancestral Mohawk Delta building into former Lake Albany. The sedimentary petrology, sedimentary structures, and cementation history of the outwash gravel deposits can be discussed in detail at the outcrop. The 3-D exposures of partially cemented, cross-bedded gravels are representative of the surficial unconfined aquifer system which provides groundwater to many communities in the Schenectady area. The locality is easily accessible via Route 5 westbound, and is an excellent site for sample collection. I use specimens from this quarry as teaching tools in many of my geology classes.
