    Science- Grade 2

    Cycle 3 43 Days The recommended number of days/lessons is less than the number of

    days in the grading cycle to accommodate differentiated instruction, extended learning time, and assessments days. Jan 8-Mar 9, 2018

    Unit # of Days/Lessons

    Texas Essential Knowledge and Skills/Student Expectations (TEKS/SEs) The student will:

    Unit 10: Weather In this unit, students will observe and record weather conditions and seasonal changes, and explore the processes in the water cycle.

    Suggested Pacing:

    ________-________

    Unit 10: Weather (8 lessons) 2.8A measure, record, and graph weather information, including temperature, wind conditions, precipitation, and cloud coverage, in order to identify patterns in the data 2.8B identify the importance of weather and seasonal information to make choices in clothing, activities, and transportation

    Sample Test Item 2.8A Weather I 2.8B Weather II

    Notes to Teacher • Students should be given opportunities to use tools to measure and record weather data.

    • Students should understand that weather data shows patterns and can be recorded in charts, tables and graphs.

    • Students might think that collecting weather data is not important, but it helps us make important decisions every day.

    Science Background Information

    Model how to use the weather instruments listed below and how to record their information before students engage in activities. Rain gauges measure the amount of rainfall, read in hundredths of an inch. The water level is read at the bottom of the meniscus (curved surface of water in a tube). Most rain gauges have numbers divided into tenths of inches. If the rain gauge is filled to the .50 line, that means that .5 of one inch or one-half inch of rain has fallen. Larger lines are inches, so if the line reads .50 above the 1-inch line, then one and a half inches of rain has fallen.

    Science- Grade 2 Wind socks (Kindergarten and 1st grade tool), used at many airports, for example, indicate relative wind speed and direction. Wind is caused by air pressure. Wind speeds change when different air pressures occur. Cool air forms high-pressure areas and hot air forms low-pressure areas. Cool air is above hot air and as it pushes down this cause wind. The larger the temperature differences between the high and low-pressure areas the higher the wind speed. The spin of the Earth also causes the air masses to move from west to east in the United States. Meteorologists use anemometers made of spinning cups to record wind speed. However, 3rd grade students will explore wind direction using a weather vane model constructed in the classroom and used outdoors. Wind vane (2nd grade tool), is a device that measures the direction of the wind. The use of a wind vane is usually combined with the anemometer. It is important to understand that wind direction is reported as the direction from which the wind is blowing. This can be confusing for young students because the wind vane points toward the direction that the wind is blowing, the exact opposite of the reported source direction. Thermometers measure temperature. Although Celsius temperature is used in the laboratory, Fahrenheit temperature is often reported on weather maps in the United States. The Teacher Toolbox has a helpful section on how to read and use both types of thermometers in the classroom. To prepare students for their weather investigations, try using simple symbols on a bulletin board for students to use to record daily weather information, such as a Sun without clouds or a Sun with partial clouds, or clouds with no Sun, rain falling from clouds, snow falling from clouds, hail or sleet falling from clouds. A paper thermometer with a movable red column can be changed to match the number of degrees on the actual thermometer. A large paper rain gauge with a moveable blue column can be changed to match the amount of rainfall in the actual rain gauge. Similarly, a large paper wind sock that has 3 or 5 positions of a paper sock can be changed to match the amount of wind on the actual windsock. Students will find out if the day will bring rain that might cancel a sport game, if it is cold enough for a jacket, or snowy enough for sledding. These are good reasons why paying attention to the daily weather information is important. The clothing business relies on bringing in a large amount of their income from rain and snow gear, like umbrellas, rain coats, snow boots, and parkas. Winter tourist attractions rely on snow and ice to help pack the mountain ski runs. Summer tourist attractions rely on clear weather at local beaches. Travelers to foreign countries usually check the climate for that region to plan activities, transportation, and clothing during the time of their visit. Students’ recess activities are often determined by the weather forecast. Even the closure of schools and business can be caused by severe weather. The recent hurricanes that devastated coastal cities profoundly affected human activity to the degree that many families lost everything in the storm and had to relocate. Personal inconveniences and huge financial risks are at stake when airlines have to cancel or reroute flights due to inclement weather. Long-term droughts can seriously affect farmers’ crops and impact the cost of groceries. Weather and climate directly impact human activity in both small and large ways.

    Essential Questions

    • What tools can we use to gather weather information?

    • How can we record weather data?

    • What weather information do we use to decide about clothing, activities, and transportation for the day?

    Science- Grade 2 —Inquiry Questions—

    • If it is raining in the morning, does that mean it will rain all day?

    • Does it always rain when clouds are in the sky?

    • Why does weather change?

    Key Science Concepts

    • We use tools such as rain gauges, wind vanes, and thermometers to gather weather information.

    • We can record weather data in charts, tables, and graphs.

    • We use weather and climate information to make decisions about clothing, activities, or transportation.

    Sample Test Item 2.8C Water Cycle

    Notes to Teacher • Students should be given opportunities to explore the stages of the water cycle.

    • Students should understand that the water cycle and weather conditions are connected.

    • Students might think that the water cycle does not affect the weather, but evaporation, condensation and precipitation occur because of changes in waters state during the water cycle.
