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.
قم بالتجربة مع بالون هيليوم، منطاد ذو هواء ساخن، أو كرة صلبة مليئة بالغازات المختلفة. اكتشف ما الذي يجعل بعض البالونات تطفو ويجعل البعض الاخر يغرق.
لماذا يلتصق البالون بكنزتك؟ قم بفرك البالون بكنزتك, ثم دع البالون و ستجده يطير و يلتصق بالكنزة. شاهد الشحنات على الكنزة, على البالون, و على الجدار.
This learning video uses a simple analog setup to explore why earthquakes are so unpredictable. The setup is simple enough that students should be able to assemble and operate it on their own with a teacher's supervision. The teaching approach used in this module is known as the 5E approach, which stands for Engagement, Exploration, Explanation, Elaboration, and Evaluation. Over the course of this lesson, the basic mechanisms that give rise to the behavior of the simple analog system are explained, and further elaboration helps the students to apply their understanding of the analog system to complex fault systems that cause earthquakes
This video lesson aims to motivate students about chemistry and to raise their awareness about how chemistry helps in solving certain environmental problems. In this lesson, the air pollution problem created by cars and other vehicles is presented. The lesson will highlight causes of this problem, harmful products from it and possible solutions. There will also be discussion of ways to convert the pollutants produced by burning oil in vehicles into more friendly products.
Follow Simon, Anita and Dennis as they join Hannah, a local scientist, in making new discoveries at Willow Creek.
كم عدد السعرات الحرارية في الأطعمة المفضلة لديك؟ كم تدريب سيكون عليك القيام به لحرق هذه السعرات؟ ما هي العلاقة بين السعرات الحرارية والوزن؟ قم باستكشاف هذه المسائل عن طريق اختيار النظام الغذائي والتدريب ومراقبة وزنك باستمرار.
العب الهوكي مع الشحنات الكهربائية. ضع الشحنات على الجليد، ثم قم بضربة البداية لمحاولة توصيل القرص المطاطي الى داخل المرمى. شاهد الحقل الكهربائي. تتبع حركة القرص المطاطي. اجعل اللعبة أكثر صعوبة من خلال وضع أسوار أمام المرمى. هذا هو استنساخ لعملية المحاكاة الشعبية التي تحمل نفس الاسم و يتم تسويقها من قبل أكاديمية برمجيات الفيزياء والتي كتبتها البروفيسورة روث شاباي من قسم الفيزياء في جامعة ولاية نورث كارولينا.
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.
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!
In this activity, learners use their hands as tools for indirect measurement. Learners explore how to use ratios to calculate the approximate height of something that can't be measured directly by first measuring something that can be directly measured. This activity can also be used to explain how scientists use indirect measurement to determine distances between things in the universe that are too far away, too large or too small to measure directly (i.e. diameter of the moon or number of bacteria in a volume of liquid).
This task can be used as a quick assessment to see if students can make sense of a graph in the context of a real world situation. Students also have to pay attention to the scale on the vertical axis to find the correct match.
Short exercise designed to give students practice in determining what information is needed to answer a question, estimating an answer, and calculating an answer (including unit conversions and scientific notation). Emphasizes the relevance of large numbers to society (population, debt, etc).
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.
Packet of activities to assist in explaining solar and lunar eclipses, night and day, the four seasons and much more.
A dynamically simplified solar system is constructed from online data to explore the real solar system on many different scales.
The realistically scaled solar system is surprising because nothing is visible due to the presence of many different scales. That is why it is usually rescaled in animations or illustrations. This is nice but gives us a wrong sense of distances and sizes. This Demonstration is intended to show the solar system's different scales in their full glory.
Since it is hardly possible to see anything when the real scales are used, controls have been added to modify the sizes of the celestial bodies.
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.
