Transcript Sleep loss affects gene function. Harry Potter's World Renaissance Science, Magic, and Medicine - Science. Road salt can change sex ratios in frog populations: Naturally occurring leaf litter can also alter sex outcomes. Naturally occurring chemicals found in road salts commonly used to de-ice paved surfaces can alter the sex ratios in nearby frog populations, a phenomenon that could reduce the size and viability of species populations, according to a new study by scientists at Yale and Rensselaer Polytechnic Institute (RPI).
The researchers found that the proportion of females within tadpole populations was reduced by 10 percent when exposed to road salt, or sodium chloride, suggesting that the salt has a masculinizing effect. They also found that exposure to fallen oak leaves also significantly altered the sex ratios in the frog populations, as well as the size of individual females in some cases. Maple leaf litter, on the other hand, had no effect. More than 22 million metric tons of road salt is applied to roads in the United States each year.
Maple and oak trees are dominant trees throughout temperate North America. The results were published in the Canadian Journal of Fisheries and Aquatic Sciences. Template - hybrid.pdf. Aurochs.pdf.

A chance to make a film about evolution and win a prize! Scientists and science educators of all stripes -- students, postdocs, faculty, and full- or part-time science communicators -- are invited to enter the Seventh Annual Evolution Video Competition, sponsored by the Duke Initiative for Science & Society, the Howard Hughes Medical Institute, the Society for the Study of Evolution, and the BEACON Center for the Study of Evolution in Action. To enter, please submit a video that explains a fun fact, key concept, compelling question, or exciting area of evolution research in three minutes or less. GoldFishLab. Origami Birds.

BetterLesson - Adaptation and Evolution of Populations: The Case of the Peppered Moth. In this section of lesson students elaborate on what they have learned through the Peppered Moth simulation by reading a passage from Readworks.
The passage, titled Naturally Selected to Survive, can be found for free by going onto that site, and searching for the title. The lexile level is 1090L, and there are a number of online resources that can be used to modify printed material to different reading levels. (Google app tldr (too long didn't read), Rewordify) The passage discusses in detail the environmental changes caused in England by the Industrial Revolution, and changes to the moth population as observed by scientists over the next 100 years. In having your students read this article, consider their academic language level which is different than their social language level. Once students have read the passage, they answer a series of Text Dependent questions that assesses their comprehension of text.
BetterLesson - Natural Selection - Survival of the Fittest. In this section of lesson students read an article on Natural Selection from cK-12. 1.
Inherited vs Acquired Traits. The Perfect Beak NGSS. To begin the lesson, have students complete the anticipation guide about natural selection, in order to gauge the students’ prior knowledge.
Review the guide together as a class, making note of misconceptions that students hold; you will want to tweak this lesson in order to address the specific needs of your students. Let students know that we will be exploring these concepts in a few simulation activities. Moby%20Pink-AIMS.pdf. Bird Communication. Have you ever wondered what birds are saying as they sing, call, quack, and drum?
With these dynamic activities, you and your students will investigate why and how birds communicate and learn to appreciate the songs you hear everyday. Your download includes the Lesson Plans and Student Journal. Students will… increase their awareness of the sounds they hear outside.be able to list the functions of bird calls and songs.use evidence to evaluate hypotheses about why birds communicate. Here are the four bird vocalizations mentioned in the Bird Communication lesson. Action%20potential%202013%20lessons.
