انضم إلى سيمون، أنيتا، إميلي وباقي فصل السيدة باتيل عند استيعابهم لطريقة عمل الأرض كمنظومة أثناء التحضير لنهاية مسرحيتهم المدرسية السنوية.
In this interactive game adapted from the Bigelow Laboratory for Ocean Sciences, build a food web that illustrates the flow of energy in an Antarctic ecosystem and the relationships between predators and prey.
ان موضوع هذا الفيديو الخاص بالوحدة النمطية هو كيفية تصنيف الحيوانات على أساس مدى ارتباطهم. ان الهدف التعليمي الرئيسي هو أن الطلاب سيتعلمون كيفية انتاج أشجار متطورة السلالات على أساس الخواص الفيزيائية وعلى تسلسل الحمض النووي معا. سيتعلم الطلاب أيضا لماذا تكون الموضوعية والطبيعة الكمية لتسلسل الحمض النووي هي الأفضل حين يتعلق الأمربتصنيف الحيوانات على أساس مدى ارتباطهم. تشمل معرفة المتطلبات الأساسية لهذا الدرس أن يتوفر لدى الطلاب بعض الاستيعاب لطبيعة الحمض النووي وأن يكون لديهم الإلمام بقاعدة-قواعد الاقتران ومع كتابة تسلسل الحمض النووي.
The Daisy World model is intended to illustrate a mechanism through which biota might optimize their environment by means of negative feedback. The model offers a very simplified approach to a feedback system and can provide an introductory lesson in how models work. The aim of the model is to implement and test a mathematical model describing possible influence of biota on an abiotic (climatic) system using GAWK and GNUPLOT. The model tests the hypothesis that biota can influence the planetary environment. This site contains the online model of Daisy World for use in introductory courses as well as an assignment based on the model.
Follow Simon, Anita and Dennis as they join Hannah, a local scientist, in making new discoveries at Willow Creek.
Scientists who are working to discover new medicines often use robots to prepare samples of cells, allowing them to test chemicals to identify those that might be used to treat diseases. Students will meet a scientist who works to identify new medicines. She created free software that ''looks'' at images of cells and determines which images show cells that have responded to the potential medicines. Students will learn about how this technology is currently enabling research to identify new antibiotics to treat tuberculosis. Students will complete hands-on activities that demonstrate how new medicines can be discovered using robots and computer software, starring the student as ''the computer.'' In the process, the students learn about experimental design, including positive and negative controls.
How many calories are in your favorite foods? How much exercise would you have to do to burn off these calories? What is the relationship between calories and weight? Explore these issues by choosing diet and exercise and keeping an eye on your weight.
In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano. This activity is a fun way for learners to investigate the sizes of different objects.
This video lesson shows students that math can play a role in understanding how an infectious disease spreads and how it can be controlled. During this lesson, students will see and use both deterministic and probabilistic models and will learn by doing through role-playing exercises. The primary exercises between video segments of this lesson are class-intensive simulation games in which members of the class 'infect' each other under alternative math modeling assumptions about disease progression. Also there is an occasional class discussion and local discussion with nearby classmates.

Build a gene network! The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.
تُوثِّق صفحة الويكي هذه لتحدي تصميم المنحنى الشمسي المستوحى من منحوتة حديقة المزرعة المائية "المنحنى الشمسي" بهدف تحدي المعلمين والطلاب بأن ينتجوا مواد جديدة للموارد التعليمية المشاعة ويدمجوا فكر التصاميم البيئية داخل الفصول المدرسية.
In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.
CK-12 Life Science Honors For Middle School covers seven units: Understanding Living Things; Cells: The Building Blocks of Life; Genetics and Evolution; Prokaryotes, Protists, Fungi, and Plants; The Animal Kingdom; The Human Body; and Ecology.
At Inside Mathematics, we’ve assembled multiple ways for educators to begin to transform their teaching practices. You might be in search of materials and tasks you can use immediately with your students; you can search by grade level and content area below to find core mathematical principles as well as materials developed by the Mathematics Assessment Resource Service (MARS). If you want to develop your understanding of the national Common Core Standards for Mathematical Practice, you can view connections between the standards and classroom videos. Here you will be able to observe exemplar lessons in different content areas and grade levels related to MP.8
Insert channels in a membrane and see what happens. See how different types of channels allow particles to move through the membrane.
This Protein Purification video lesson is intended to give students some insight into the process and tools that scientists and engineers use to explore proteins. It is designed to extend the knowledge of students who are already somewhat sophisticated and who have a good understanding of basic biology. The question that motivates this lesson is, ''what makes two cell types different?'' and this question is posed in several ways. Such scientific reasoning raises the experimental question: how could you study just a subset of specialized proteins that distinguish one cell type from another? Two techniques useful in this regard are considered in the lesson.
Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?

This activity lets learners participate in the process of reconstructing a phylogenetic tree and introduces them to several core bioinformatics concepts, particularly in relation to evolution. Groups of learners (at least 10) repeat a secret message (five to seven similar-sounding words) like the game "Telephone". In this version of the game, however, learners write and then code what they hear, creating a model of a phylogenetic tree and using a species distance matrix. This resource includes background information about phylogenetic trees, maximum parsimony, and matrix theory (see page 6-7 of PDF).
