Activity No. 2: Experimentation (15 Minutes) 11. Objective(s): At the end of the lesson, the learners shall be able to: a. conduct an experiment to prove hypothesis; and b. determine the procedure in a given experiment. III. Materials Needed: Reading Material, activity or science notebook IV. Instructions: Experiment Procedure For this activity, the students will be grouped into four. Each group will have their assigned station. On each station, there will be illustrations, text, and simple simulations to show the experimentation Reading/Viewing Guide STATION 1 (Figure A) Manuel is a farmer. He noticed that there were mice that were pests on their rice crops. Their harvest of rice crops decreases. The supply of rice affected their town. Which resulted in a high price of rice. He uses three steps. First, he mixed 20g bait phosphorus material into the soil; second, he placed a scarecrow on the farm and lastly, he planted peppermint in between the rice crops. FigureA STATION 2 (Figure B) Figure B Mary's mother is a "plantita". During the pandemic, she planted tomatoes. Because of lack of space, some tomatoes were planted on the garden soil, while others were on the small pots. She observed that her plant growth and its fruits differ, although she planted them simultaneously. Because of lack of space, there were tomatoes planted in the garden, others were in small pots. The tomatoes planted in the garden receive enough sunlight. The tomatoes planted on the pots were placed inside their house. Both were watered and were given the same amount of fertilizers,STATION 3 (Figure C) During the Brigada Eskwela, teacher Mara is cleaning her room. She mops the floor and cleans the board and chairs.

His mom told him to put a slice of bread inside an air- tight container, the other alice to put in a paper bag and the remaining slices he left in the bread plastics. Guide Questions 1. How many experiments were done in each station? 2. Can you describe the procedure of the experiment on the first station? How about the 2nd? 3rd? and 4th station? 3. Which of the experiments in the first station worked? How did you say so? How about the 2nd station? 3rd station? 4th station? 4. How will you say that the experiment worked well? 5. Does the experiment show a fair testing? How did you say so?​
