NSDL Resources Highlight Solstice Science and Math

Winter officially begins during the third week of each December in North America. This calendar event known as the solstice is marked as the sun briefly “stands still” as its position in the sky reaches the greatest distance from the earth. This celestial alignment is experienced as the shortest day of the year by people in the northern hemisphere as they rush about making holiday preparations. Many cultures celebrate the winter solstice with community gatherings that ritually create more light and warmth during the longest night.

This photograph of the “Tyrrhenian Sea and Solstice Sky” by Danilo Pivato was featured in Astronomy Picture of the Day: “This stiking composite image follows the Sun’s path through the December Solstice day of 2005 in a beautiful blue sky, looking down the Tyrrhenian Sea coast from Santa Severa toward Fiumicino, Italy. The view covers about 115 degrees in 43 separate, well-planned exposures from sunrise to sunset.” Used with permission © Danilo Pivato, 2005, All rights reserved.

The following NSDL resources are designed to shed light on solstice math and science:

From PRISMS: Phenomena & Representations for Instruction of Science in Middle Schools

Earth-Sun Geometry: Winter Solstice Animation

This representation depicts the position of the Earth relative to the Sun during the southern hemisphere’s winter solstice and includes line of latitude and the angle of the Sun’s rays at the Tropic of Capricorn.  More information here.

From NSDL Engineering Pathway partner TeachEngineering: Resources for K12

Portable Sundial

Students will investigate the accuracy of sundials and the discrepancy that lies between “real time” and “clock time”. They will track the position of the sun over the course of a relatively short period of time as they make a shadow plot, a horizontal sundial, and a diptych sundial. More information here.

The Reason for the Seasons

Understanding why the earth has seasons is one of the most difficult concepts for middle school students to understand. This publication provides resources to help teachers uncover their students misconceptions about the seasons. More information here. 

From the GLOBE Program:Global Learning and Observations to Benefit the Environment, and DLESE: Digital Library for Earth System Education 

Modeling the Reasons for Seasonal Change

The purpose of this resource is to understand what causes the Earth’s seasons with a focus on the Earth’s tilt and spherical shape. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. More information here.

Teachers Test NSDL’s Science Literacy Maps

NSTA’s Science Scope is a peer-reviewed journal for middle level and junior high school science teachers. In the November 2008 issue authors Kerri Richardson, Catherine Matthews and Catherine Thompson offered on-the-ground insights into why proportional reasoning is particularly important for middle school teachers to understand in order to instruct their students in developing inquiry skills. Their article, “Linking Proportionality Across the Science and Mathematics Curricula Through Science Literacy Maps” takes a look at the powerful combination of high quality National Science Digital Library (NSDL) resources delivered through information and concepts represented in Science Literacy Maps as a way “to help students construct their own meaning.”

blog_sci_map.jpgThe strand maps developed by Project 2061 at the American Association for the Advancement of Science and published in the Atlas of Science Literacy, Volumes 1 and 2 (2001 and 2007, AAAS Project 2061 and the National Science Teachers Association) are also available as large format books.

The knowledge system that underlies NSDL’s Science Literacy Map Tool is the Atlas of Science Literacy maps that have been published by the American Association for the Advancement of Science (AAAS) and Project 2061. The article describes the Atlas and the NSDL-developed Science Literacy Map Tool as a way for teachers to understand science literacy and to align instruction with state and national standards.

The authors asked 50 middle school teachers to complete tasks and present their findings. After completing a set of 8 tasks related to thematic mathematical concepts represented on maps the group concluded that the content and process were a good match in finding appropriate resources for use in instruction. One teacher group reported, “[the science literacy maps] put it together in a big picture for us and gave us new meaning.”

The full article is available through the NSTA web site. NSTA members may access it for free. Cost to nonmembers is .99: http://www.nsta.org/store/product_detail.aspx?id=10.2505/4/ss08_032_03_64.

WGBH Teachers’ Domain Reaches Out to Student Video Producers and Makes Media More Accessible

“Youth Voices” is an open call from WGBH Teachers’ Domain for ideas from 13-18 year olds who would like to produce video segments about climate change. “Youth Voices” will kick off in January, with a series of three informative webinars for student filmmakers. To find out more check out WGBH Lab for details. Teachers’ Domain is also working to create science curriculum units that are accessible to blind and low-vision students.

blog_wgbh.jpgThe WGBH Lab web site. Follow the WGBH Lab Twitter feed for up-to-date news and information.

How do you teach a blind child about the wonders of the solar system? Or the anatomy of a frog? Thanks to funding from the National Science Foundation’s Research in Disabilities Program and additional funding from The Grousbeck Family Foundation, WGBH’s National Center for Accessible Media (NCAM) worked with the Perkins School for the Blind in Watertown, Massachusetts to create science curriculum units that are accessible to blind and low-vision students.

Teachers’ Domain asked Veteran Perkins instructor Becky Hoffman who wanted science to come alive for her students: How will Teachers’ Domain resources help your students? And how do you plan on using them in your classroom?

Hoffman responded: “One of my most time-consuming jobs is reformatting materials, so being able to turn to the Teachers’ Domain website for accessible lesson plans will leave more time for teaching-a definite plus. I am also hopeful that other teachers of the visually impaired will find the modifications and suggestions helpful for their students.”

“We feel that science should provide our students with concrete, functional lessons that they can relate to on a personal level, Hoffman adds. “Subjects such as growth and development, the weather, life cycles of plants and animals, nutrition, our bodies, basically things that affects their lives, are good topics to explore with our students. Teachers Domain covers these topics and with modifications and suggestions, we can use the website to enrich our science program.”

Teachers’ Domain hopes that these developments will enable teachers of the visually impaired across the world to make science come alive for their students.

Can You Taste It?

Few people are aware of how crucial the sense of smell is to identifying foods, or the adaptive value of being able to identify a food as being familiar and therefore safe to eat. In this lesson and activity, students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste.
