Inside the Lab See how we breathe Make sure you do this activity only with You will need: the help of your teacher or an adult. three balloons, a pair of scissors, a knife, a large plastic bottle, two straws (that can be bent), clay and duct tape. You need to: a) b) Bend the straws at an angle. Insert the bent ends of the straws inside c) the balloons as Attach the straws to shown in the picture. each other forming a Secure them using ‘Y’ shape as shown in the duct tape. the picture. d) Add a ball of clay around the straight ends of the straws, leaving the holes of the straws open as shown in the picture. e) Place the straws in a bottle, and secure the opening of the bottle with clay as shown in the picture. f) 23 Cut the bottom of the bottle. Remove the neck of a 11-12-2019 16:00:44 balloon. Stretch the balloon to cover the bottom of the bottle. Secure it with a rubber band as shown. (The teacher should help the learners while cutting.) PNC_G3_SCI_T3_WB.indb 23

f) Cut the bottom of the bottle. Remove the neck of a balloon. Stretch the balloon to cover the bottom of the bottle. Secure it with a rubber band as shown. (The teacher should help the learners while cutting.) g) Now, blow air into the straws. What do you see? When the air comes out from the bottle, what do you see? The balloons in the bottle act as the lungs, and the balloon that is stretched at the bottom of the bottle acts as the diaphragm. When you blow air into the balloons, they expand. When the air comes out of the balloon, they return to their normal size. This is how we breathe in and breathe out air. 1) How can we explain the process of breathing using the model prepared?

Term Project Web of life Make sure you do this activity only with the help of your teacher or an adult. Let us create food chains using picture cards of animals. You will need: scissors, gum, chart papers, pictures of different plants/plant parts like grass, vegetables, fruits, cereals, pulses and pictures of animals. (Example: earthworm, grasshopper, rabbit, deer, elephant, wolf, lion, tiger, eagle, frog, fish, snake, hen, crow, crane, duck, squirrel, cow, cat, dog, mouse and human being.) You need to: a) Use a pair of scissors to cut the chart paper into equal-sized pieces. (Take help of teacher/adult while cutting.) b) Paste the pictures of plants and animals on the chart paper pieces to make picture cards. Your game cards are ready. c) Find out how many different combinations of food chains you can form using them. For example, grass, grasshopper, frog, snake and eagle will form one chain, while plant, rabbit and wolf will be another chain. 25 PNC_G3_SCI_T3_WB.indb 25 11-12-2019 16:00:48
