1 ACTIVITY-1 Which month has larger and smaller day time? Problem: Which month has larger and smaller day time? Aim: Finding out which month has larger and smaller duration of day in the Year Format for Observation Table Tools: Wall calendar mentioning sunrise and sunset time. Procedure: To do the experiment fallow the below procedure. 1. Get the calendar which shows sunrise and sunset time for each day of the year. 2. Fill the observation table with the time of Sunrise and Sunset. Theory: There are countable reasons for larger and smaller duration of the day and night. Some of them are: (i) Earth rotate on its axis (ii) Earth s axis of rotation is not exactly vertical (iii) Earth is spherical in shape and hence observers position on the globe is not same for all etc. All these reasons give rise to the difference in length of the day and night.

2 ACTIVITY-2 Path of the Sun in the Sky Aim: Tracing out path of the Sun in the Sky. Tools: Comparatively dark room, Calendar and Watch. Procedure: To do the experiment follows the procedure below. 1. Find the room having window/door facing the sun. 2. Make the room darker by closing the doors and windows but keep a small portion of the window open through which sunlight can come. (Better through a small hole). 3. If your window is glass window then get a black paper of the size of window and make a small hole through which sunlight can come. Now paste this dark paper on the window. 4. Allow sunlight to come through the hole in the form of beam that can fall on the floor. 5. Set the time in the watch (this will remain same for all observation dates in future days, preferable time could be 1200 hrs). 6. Mark the beam position on the floor as shown in figure 1. Now repeat the procedure for all the observation dates. Theory: If you observe the sun in the sky quite frequently then you will observe that the sun s position is not same everyday. It goes on changing. Of course it is true that the sun is not moving but it is the Earth! In reality what we observe is the sun s changing position throughout the year. Observation Table Result : Draw the figure of traced marking available on the floor. Now connects all the points with free hand (smooth curve).

3 ACTIVITY-3 What are Dakshinayan and Uttarayan? Aim: Understanding the Dakshinayan (Sun s declination to South) and Uttarayan (Sun s declination to North). Tools: 1 meter stick, Calendar and Watch. Procedure: To do the experiment follows the procedure below. 1. Locate the plane surface from where you can see the Sun without any obstacle. 2. With the help of magnetic compass mark the South- North line on the ground and furthermore East- West line; crossing each other in an exact proportion. This will make 4 quadrants as shown in figure below. 3. Fix meter stick exactly at the intersection of these lines i.e. at the origin (point O). Be sure that the stick is Direction at observation location & exactly perpendicular to the plane surface. You can use Shadow length plumb line to see the exact verticalness of the stick. 4. Fix the day time observation which is to be constant for all the year. 5. Shadow of the stick will fall in any one of the quadrants made earlier. 6. Mark the tip of the shadow as a point in the quadrant. 7. Mark such points for four dates in the year. For more details look at the observation table. Theory Ayan means movement. Dakshinaya and Uttarayan indicate the Sun s movement to South and North respectively. The correct definition is the sun s declination to North or South. Since the earth s axis is tilted by 23 ½ degree, the sun appears more to the north for 6 months and to the south for rest of the 6 months in a year. This is the reason that we experience winter in the northern hemisphere and summer in the southern hemisphere at the same time e.g. Australia is cold and India is hot at same time. Sun reaches its maximum to the south (South declination) on 21 December and to the north (North declination) on 21 June. These are called Winter and Summer Solstices respectively. These dates may vary with ±1 or ±2 days. Observation Table Time of Observation: 8:00 AM (You can fix up any day time!) Result : Draw the figure similar to what you observed at your observation location.

4 ACTIVITY-4 Phases Of The Moon Aim: Understanding the phases of the Moon Tools: Notebook, pencil, eraser etc Procedure: To do the experiment follows the procedure as given below :- 1. Select the Full moon day from your calendar. 2. Start observing moon s phase in the night sky. 3. Draw the phase of the moon in observation table as you see in the night sky. 4. Go on repeating the drawing as mentioned in the observation table. 5. Complete the observation table. Theory: Moon is the natural satellite of Earth. And hence, moon revolves around the Earth. As shown in the diagram below, the new moon occurs when the moon is positioned between the earth and sun. The three objects are in approximate alignment. The entire illuminated portion of the moon is on the back side of the moon, the half that we cannot see. At a full moon, the earth, moon, and sun are in approximate alignment, just as the new moon, but the moon is on the opposite side of the earth, so the entire sunlight part of the moon is facing us. The shadowed portion is entirely hidden from view. The first quarter and third quarter moons (both often called a half moon ), happen when the moon is at a 90 degree angle with respect to the earth and sun. So we are seeing exactly half of the moon illuminated and half in shadow. Once you understand those four key moon phases, in between should be fairly easy to visualize, as the illuminated portion gradually transit between them. Observation Table Result: 1. After. days we saw the Full moon again. 2. On 15/16th day after Full Moon we saw.. Moon. (Full/Half/New) 3. The night when you could not see the Moon is called

6 ACTIVITY-6 Composition of different colors in the Sunlight Objective: Understanding how many colors sunlight have. Material required: prism, pen and notebook. Procedure: 1. Arrange comparatively darker room. 2. Allow very small sunlight to pass in the room; may be through hole. 3. Put the prism across the sunlight. 4. Now look at the darker region of room. 5. You will see the different colors of sunlight. 6. Note down the colors that you have seen. Explanation: The observed sun light always look yellowish in color that is because sun emits maximum light in yellow wavelength/ frequency such light is called as white light. But actually white light is not a single wave length/ frequency in nature, it is a combination of all seven colors viz. red, orange, yellow, green, blue, indigo and violet. As shown in figure To conform this, one has to perform above experiment. One can also see the different colours of light on a Compact Disk used in computers made out of very tiny magnetic strips/ grooves whose size is in micron. When sunlight falls on the CD or on this strips/grooves sunlight is get diffracted in different wavelength/frequency and hence we see the different wavelength lights as different colors. Please remember CD can not be prism which can give large angle diffraction. Observations: 1. Write the colors that you have seen. Ans: 2. Write the colors in a sequence; as they appeared.

7 ACTIVITY-7 Observation on full moon days why we see only one side of the moon? Aim: Observation of Moon on every Full moon day. Apparatus: Telescope, calendar, drawing paper, pen/pencil Procedure: Do the following: 1. With the help of calendar, locate any approaching Full moon day. 2. Note the date of observation. 3. Point the telescope towards Moon. 4. Observe the moon thoroughly. 5. Try to draw an image of Moon in the observational table. 6. If you are good enough for taking the photographs through the telescope then capture the photograph of Moon. 7. Follow the above procedure for next few Full moon days and draw the image of Moon or take the photographs. Theory: Astronomical objects revolve around its parent object e.g. Moon revolve around Earth, Earth revolves around Sun, Sun revolves around center of galaxy etc. While most of them rotate on its axis. This holds true for Earth and Moon as well. Earth rotates around its axis and takes 24 hours to complete one rotation. The fact is true for Moon as well! i.e. Moon rotates on its axis at same rate within 24 hours. Therefore, Moon being a natural satellite revolve around the Earth, hence we see only one side of the Moon all time from Earth. The only way to see the other side of moon is to send a space probe that can fly to other side of the moon. Result: Are the images/photographs same? If yes, why? Ans: What you understood from this experiment?
