3. Explore: How the Sun Warms Water Question: What can you observe about the temperature of water placed in sunlight? Materials: 2 cups masking tape water marker measuring cup

4. Explore: How the Sun Warms WaterWhat to Do • Label 1 cup Sunlight. Label the other cup NoSunlight. • Use a measuring cup to measure ½ cup of water. 3. Pour the ½ cup of water into the cup labeled Sunlight. • Repeat steps 2 and 3 for the cup labeled NoSunlight.

5. What to Do, continued • Hold a cup in each hand. Compare the temperatures of the two cups. Write your observations in your science notebook. • Place the Sunlight cup in the sun. Place the NoSunlightcup in the shade. • Wait 30 minutes. (continued on next slide)

6. 8. Then hold a cup in each hand. Compare their temperatures. Write in your notebook. Explain the Data: • What did you do? I compared the _________ of _______________. • What happened to the temperature of the water in the sunlight? The water in the Sunlight cup became _________ than the water in the No Sunlight cup.

7. Inquiry: Closed vs Open Question: What will happen to two containers with the same amount of water with one closed and the other left open for several days in a sunny place? Materials: 2 identical clear containers (cups) marker plastic wrap rubber band masking tape water permanent marker graduated cylinder or measuring cup

8. What to Do • Label 1 container: Closed. Label the other container: Open. • Use a measuring cup or graduated cylinder to measure 50 mL of water. Pour 50 mL of water in the first cup. Repeat for the second cup. • Mark the water line on both cups with a permanent marker. • Place a piece of plastic wrap over the top of the cup to be closed. Attach a rubber band to hold it in place. 5. Place both containers in a sunny place. 6. Observe over several days.

9. 8. Observe each cup. Record in your notebook. Repeat daily. Compare the observations. 9. On the last day, measure out how much water is left in each cup using a graduated cylinder or measuring cup. Compare. Explain the Data: • What did you do? • What happened to the amount of water in the water in the cups? What is your evidence? • What are you wondering now? Video: Water Vapor, Clouds, Dew and Frost

10. Explore: Sun Sensors, Too Materials: soil water lab sheet 4 light colored bowls or deli containers 4 thermometers Question: How can a thermometer help us know that the sun heats Earth’s land and water? Reading a Thermometer

11. Explore: Sun Sensors, TooWhat to Do 1a. Put a bowl of water and a bowl of soil in the shade. Measure the beginning temperature of both. Record. 2a. Wait about 30 minutes. Find and record the temperature of both on the Sun Sensors, Too lab sheet. 1b. Put a bowl of water and a bowl of soil in the sun. . Measure the beginning temperature of both. Record. 2b. Wait about 30 minutes. Find and record the temperature of both on the Sun Sensors, Too lab sheet.

12. Explore: Sun Sensors, TooExplain the Data • What was the temperature difference of the soil in the shade and the soil in the sun? (Show your work.) 2.

14. WEATHER Weather is hot, Weather is cold, Weather is changing As the weeks unfold. Skies are cloudy, Skies are fair, Skies are changing In the air. https://www.pearsonsuccessnet.com/snpapp/login/login.jsp?showLoginPage=true It is raining, It is snowing, It is windy With breezes blowing. Days are foggy, Days are clear, Weather is changing Throughout the year!

15. What is WEATHER ? Weather… • Tells how the air moves (wind) and describes anything it might be carrying such as rain, snow or clouds. • Thunder, lightning, rainbows, fog and other special events are all part of weather • describes the condition of the air at a particular time and place - the temperature and rainfall

16. What are the Building Blocks of Weather? • Clouds • Precipitation • Wind Video: Water Vapor, Clouds, Dew and Frost

17. What is Precipitation? Forms of Precipitation Weather Condition Rain or drops of liquid water fall from the clouds when water vapor condenses around dust particles in the clouds, forming tiny droplets that eventually get too big for the cloud to hold so they fall down. Snowform in clouds where the temperature is below freezing as ice crystals or groups of many ice crystals called snowflakes. Hail forms within thunderstorm clouds when upward moving air keeps pellets of frozen water from falling. The pellets grow larger as drops of very cold water hit them and freeze • Rain • Snow • Hail

18. What is Wind ? Wind Whoosh! Whoosh! Whoosh! Feel the wind push! Blow! Blow! Blow! Where’s my hat go? Answer: Moving Air What are some objects that wind can move?

19. Explore: What can we observe about the wind and how it moves things as we walk in our schoolyard? 1. Label a page in your science notebook: Evidence of Wind • Draw pictures of things and label them that can be moved by the wind. • Share with your group. • What evidence of wind did we see in the schoolyard? • Describe the way these objects moved in the wind? • What were some objects that did not move in the wind? Why didn’t they move?

27. Big Idea 7: Earth Systems and Patterns Grade 2 Pacing Guide Topic XIII: Severe Weather

28. Thunder and Lightning(sung to “Pop Goes the Weasel”) When a storm begins in the clouds, It sometimes may look frightening. You see a quick electrical spark- Flash! Goes the lightning! Long and thin and streaky and fast, Its glow is oh so brightening, Watch for the electric spark- Flash goes the lightning! When a storm begins in the clouds, It is truly wonderful. You hear a rumble loud in the sky- Clap! Goes the thunder! Lightning bolts are heating the air, Over clouds and under. When the air expands enough- Clap! Goes the thunder!

38. For the Teacher:Common WeatherMisconceptions • Wind originates in the trees. • Reality: Wind is a result of the sun warming the Earth’s atmosphere unevenly. • The seasons are the same everywhere. • Reality: Differing climates lead to different weather during the same season in other parts of the world. • Weather, seasons, and climate are the same thing. • Reality: Weather is the state of the atmosphere, while a season is one of the four periods of the year that begin at an equinox. Climate is the prevailing weather conditions of an area.
