Have we overstepped Mother Earth's boundaries? What are the consequences? In this video segment adapted from Haskell Indian Nations University, hear a Native perspective on our relationship with the natural environment.

This is a lesson plan that will be utilized in the classroom in order for the students to learn about the sun. The lesson plan includes a song and dance, a book, lecture, and even a poster project presented by the students. The children will be graded based off of the children's understanding of the relationship between them and the Sun.

Write an informational letter to your friend answering the question “What is an estuary and what makes them so special?”. Use information from the reading/book, video, and your experience. Includes a reading booklet.

Students at grade K are asked to write stories about what it is like to visit a beach. Students listen to a picture book, go on a nature walk, and read a booklet to give information for their story. You will also visit a local beach! Includes a reading booklet.

PLoS ONE will be a high-volume, efficient and economical system for the publication of peer-reviewed research in all areas of science and medicine. It will provide a unique forum for community dialogue using the full potential of the web to accelerate scientific progress.

Pennsylvania System of School Assessment (PSSA) includes assessments in English Language Arts and Mathematics which are taken by students in grades 3, 4, 5, 6, 7 and 8. Students in grades 4 and 8 are administered the Science PSSA. The English Language Arts and Mathematics PSSAs include items that are consistent with the Assessment Anchors/Eligible Content aligned to the Pennsylvania Core Standards in English Language Arts and Mathematics. The Science PSSA includes items that are aligned to the Assessment Anchors/Eligible Content aligned to the Pennsylvania Academic Standards for Science, Technology, Environment and Ecology.

An overview of the STEM 9 program at Pequea Valley High School in Lancaster County, PA. Most 9th grade learners take this course which teaches Algebra I math concepts via physics concepts and tech ed building.

In this interdisciplinary lesson, students will apply the Engineer Design Process to design a structure to remove waste from the Great Pacific Garbage Patch. The lesson involves components of STEM and English Language Arts. This lesson results from collaboration between the Alabama Department of Education and ASTA.

Users can choose a time in geologic history, select the link, and see what the Earth looked liked in the far distant past. Each map features a brief written description of the events occurring at that time, and a link to additional information on the geologic era or period being shown. There are also maps that show what the Earth might look like in the future, 50, 100, and 150 million years from now.

Parkinson's disease (PD) is a chronic, progressive, degenerative disease of the brain that produces movement disorders and deficits in executive functions, working memory, visuospatial functions, and internal control of attention. It is named after James Parkinson (1755-1824), the English neurologist who described the first case.
This six-week summer workshop explored different aspects of PD, including clinical characteristics, structural neuroimaging, neuropathology, genetics, and cognitive function (mental status, cognitive control processes, working memory, and long-term declarative memory).  The workshop did not take up the topics of motor control, nondeclarative memory, or treatment.

In this interactive activity from ChemThink, examine the basic properties of matter at an atomic level and consider how various atoms affect the way a substance behaves.

A 36-year-old man presented with a large nasal tumor following a long history of multiple meningiomas. At the age of 13, the patient underwent surgical resection and received a single course of radiation therapy for a left optic meningioma. He did well until age 33, when he was found to have multiple meningiomas in three new locations: falcine (Figure 1a), right petroclival and right anterior foramen magnum. These were surgically resected but no additional radiation was administered. Three years later, the patient presented with nasal symptoms, headaches, and seizures. Imaging studies revealed a large mass with intracranial and nasopharyngeal component measuring 4.1 x 5.4 x 6.8 cm in greatest dimensions and causing right frontal lobe compression (Figures 1b and 1c). A systemic workup, including PET CT, for other malignancies was unremarkable. A two-stage surgical resection was performed. The mass was initially biopsied by transsphenoidal endoscopic approach and then partially resected by bifrontal craniotomy, frontal sinus obliteration, en bloc ethmoidectomy, and nasal cavity resection.

This is a patient with chronic normocytic normochromic anemia in the range of 8 to 10 g/dl. Further testing included Iron, TIBC, folate and B12 which were within normal range. Reticulocyte count was increased. Peripheral blood smear showed many target cells, nRBC and polychromasia.

A 47 year old woman from Honduras presented with severe headache and left eye pain. An initial evaluation by a local ophthalmologist revealed no significant findings. Diagnostic imaging at the time demonstrated a sellar mass lesion. She was commenced on cabergoline, but this was ceased due to nausea, vomiting, and tumor progression. Her headaches persisted and she subsequently developed left eye exophthalmos, ptosis, and ophthalmoplegia. Follow-up CT demonstrated significant growth of the mass and involvement of the left orbital apex and cavernous sinus. She was started on corticosteroids and it was recommended she seek care of this lesion at our center.

The patient is a 10 month-old girl who was born after a full term pregnancy via cesarean section secondary to failure to progress. The pregnancy was notable for polyhydramnios, well-controlled gestational diabetes, and decreased fetal movements late in the third trimester. At birth the baby was found to have a cardiac murmur and was mildly hypotonic, with difficulty feeding. An echocardiogram at 3 months showed mild asymmetric septal hypertrophy with possible biventricular hypertrophy, which at the time was attributed to gestational diabetes. Laboratory tests at 6 months showed elevated liver enzymes. The patient's development over time was notable for delayed achievements of new motor milestones, as well as the loss of achieved milestones.

The patient is a 10 year old female, active in dance classes. She is referred to rheumatology at UPMC following a week-long bout of malaise accompanied in the last several days by a pruritic lacy rash on her trunks and limbs (Figure 1). An anti-nuclear antibody (ANA) assay obtained by the outside physician at an outside laboratory was positive to a titer of 1:1,280.
