READ THE INSTRUCTIONS CAREFULLY :-

Write the following activity and Assignments in your science note book with your observations

(questions given below)

Submission : Upload your work as pdf / google form link which will be provided later /

instructed by Teacher later.

Q1. PROJECT/ACTIVITY:

Make a sky lantern at home with kite paper and record your video and upload it in your

drive link provided by your teacher.

(https://youtu.be/-_2waZUkNOc)- video link for reference

Q2. Study of osmosis with the help of a potato.

https://youtu.be/uixn83fA5_Q

Aim: To observe how water moves between cells in plants.

Requirements: A medium-sized potato, potato peeler, knife, sugar solution, pins, bowl/ plate

and water.

Procedure:

1. Take a potato and peel off its skin.

2. Make both ends flat by cutting off thin slices with a knife.

3. From one end carefully scoop out a cavity in the potato, leaving a thin layer of potato tissue all

around the cavity.

4. Fill half of the potato cavity with sugar solution.

5. Mark the level of sugar solution inside the cavity by inserting a pin into the potato wall.

6. Now place the potato cup in a Petri plate containing water, such that most of the potato cup is

dipped in water, but the level of water is lower than that of sugar solution (See Figure).

7. Keep the set-up for a few hours and observe the level of sugar solution in the cavity.

Water moves through different cells of potato through osmosis

Precautions:

• The wall of the potato cavity should not be more than 4-5 mm thick. Take care that the wall

remains intact while scooping the potato or while inserting the pin in the wall.

• For marking the level of sugar solution inside the potato cup insert the pin at an angle with its

tip coinciding with the level of sugar solution.

• Do not fill the potato cavity with sugar solution up to its brim as it may overflow.

• Take care that the level of water in Petri-plate is lower than the level of sugar solution in the

potato cavity.

Based on the activity, answer the following questions:

1. What did u observe after few hours and wat did u conclude from the observation?

2. What is the direction of movement of water in the above experiment? Give reasons.

3. What would happen in the above experiment if –

a) the level of water is higher than that of sugar solution?

b) wall of potato is quite thick?

c) skin of the potato is not peeled off?

4. How does water move from soil to the xylem of root?

5. How does water reach from the roots of a plant to the leaves?

6. Set up another experiment by reversing the water and sugar solution in the experiment.

Observe the level of water in the potato cup after a few hours. What do you conclude?

Q3. Identify any five plants around your home , take pictures and make a collage. Write

the name of respective plants on it. Upload it in your drive folder provided by teacher.
