In this program, concise explanations of the various types of precipitation provide students with insight into how rain, snow, sleet, hail, fog and mist form, as well as how the water cycle -- evaporation, condensation and precipitation -- constantly "recycles" water around the world. Students will also learn how the density of water changes in different states. See typical weather patterns across North America, and watch how a ski resort keeps slopes looking white. One of six volumes in the Weather Fundamentals DVD Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title correlates to the National Science Education Standards for Earth and Space Science -- structure of Earth's system, Earth's history and Earth in the solar system. A Teacher's Guide is included and available online that features additional information on the topic, vocabulary words, discussion questions, follow-up activities and lists of recommended books & Internet resources. 23 minutes. Grades 4 to 7.

Professional entry into measured value acquisition with the Robotics ADD-ON IoT! Together with the Robotics TXT 4.0 Base Set, the sensor station enables the measurement of temperature, humidity, air pressure, air quality and brightness. The sensor station can be programmed and controlled with the ROBO Pro Coding programming software and the ROBOTICS TXT 4.0 Controller and is ideal for teaching topics such as measurement acquisition and transmission as well as control and regulation of actuators and sensors. The measured value acquisition is carried out via the connection of the TXT 4.0 Controller with the fischertechnik cloud, in which the sensor data is stored, collected and graphically displayed. Via the user interface, the so-called dashboard, the various sensor data are permanently recorded (real-time) and the camera, which can be swiveled in two axes, is remotely controlled. The teaching material created to accompany the Robotics ADD-ON IoT set contains 6 experiments and associated solutions.
Includes access to tutorial materials with 6 different experiments.
