Classroom Teacher Preparation Earth Science 16: Weather Please use the following to prepare for the next SfS lesson. Description: This lesson provides an introduction to weather and its key components that influence it. Key components include temperature, humidity, pressure, ocean currents and air currents. The four main types of precipitation are also included in th th the lesson. This lesson was designed to focus on weather concepts that are introduced in 4 and 5 grade, or for students who have not yet had an introduction to weather. Lesson Objectives – SWBAT (“Students Will Be Able To…”): th 4 -8 th • • • • Define weather and where it occurs in the atmosphere Understand how earth’s rotation affects the weather Understand that there are several different factors that make up the weather in a place or time, including temperature, humidity and pressure. Identify the four main types of precipitation Preparation: No special preparation is needed; this lesson is an introduction to the topic. Vocabulary: Introduce these terms: • • • • • Longitude – lines that measure distances in degrees that run east to west on a globe Latitude – lines that measure distances in degrees that run north to south on a globe Condensation – water vapor (gas) changes to liquid water Evaporation – liquid water changes to water vapor Freezing – liquid water changes to solid water (ice) These terms will be defined in lesson: • • • • • • Fronts – boundaries between warm and cold air Pressure – the weight of air pressing down on earth Rain – drops of liquid water that fall to earth’s surface Snow – water vapor frozen into ice crystals Sleet – ice pellets that form when raindrops hit a subfreezing patch of air near earth’s surface Hail – a mixture of liquid precipitation made up of layers of ice Room Set Up for Activities: The activities for this lesson will be in stations where 4-5 students will work as a group. Tables or desks pushed together are ideal for these stations. There should be some paper towels kept at every station that contains water. Instructors will need a place to dump the used water from the Thunderstorms activity – if there is a sink available that would be best.

Students should be aware of the location of the kettle and not touch it. One activity involves a mixture of 70% rubbing alcohol with water and food coloring. Students are not allowed to drink this. Related Modules: This lesson may be taught as part of a sequence or group of related modules on Weather. Other modules in this sequence include: Chemistry 11: States of Matter – For younger students, this module introduces the three commonly-observed states of matter (solid, liquid, gas), the most commonly-occurring one (plasma, which makes up the stars), and allows them to observe many of the transitions between the different states. For older students, the topic is connected to heat transfer, as they consider how the flow of energy between materials allows the transitions to occur. Earth Science 17: Meteorology and Weather Mapping - Students will learn about weather patterns, weather symbols, and how to interpret a weather map. They will then use the skills they have learned to highlight the weather on a national weather map and identify pressure systems and weather fronts. For other module sequences and groups, look here: www.sciencefromscientists.org/sequences Standards Covered: Please click the following link to our website to review the standards covered by this lesson, listed by state: http://www.sciencefromscientists.org/standards/ Lessons are matched to both national NGSS and local state standards. Classroom Post and Activities: A link to the Follow Up Student activity can be found in the Classroom Post on our website at sciencefromscientists.org/cohorts. Use the name of your school/cohort and password to log in. Students will build and test their own barometer for measuring atmospheric pressure, which can help predict weather.
