A teacher along with his students is carrying out a study on germination of seeds. They take some dry seeds of different kinds and plant them in different physical conditions. They observe, measure and discuss the growth over a period of time. During the course of the activity, teacher asks questions which require various process skills. The questions asked by the teacher are given in column I Match these with the appropriate process skills Column I Column II (A) What are the differences between seeds of different type (i) communication (B) Why do you think some seeds are growing more quickly than others? (ii) predicting (C) Draw a diagram to depict the changes in the seeds (iii) observing (D) Based on your observation what do you think would happen if we double the amount of water (iv) hypothesising

In simple words, Science process skills are the processes that are being used by various scientists while doing science. Some common science process skills are Observing, Classifying, Communicating, Measuring, Predicting, and Inferring.
Key Point(A)- What are the differences between seeds of different types? this question allows students to make observing regarding seeds.
- Observing means using our various senses to obtain information (or data) about objects or events attended”. Observations are not to be limited to seeing things only. We use more than one sense organ to collect data (or information) about the objects in our daily acts.
(B)- Why do you think some seeds are growing more quickly than others? this allows students to their hypotheses.
- A hypothesis is a tentative generalization, the validity of which remains to be tested. In its most elementary stage, the hypothesis may be any guess, hunch, imaginative idea, which becomes the basis for action or investigation”.
(C)- Draw a diagram to depict the changes in the seeds this will enhance the communication skill of students.
- Communication in science is a specialized skill through which scientific knowledge is being shared and communicated among the scientific community.
(D)- Why do you think some seeds are growing more quickly than others? this question asks the students for the reason of enhancing predicting skills after their observations.
- Predicting is to forecast what a future observation will be. Predictions are based on our observations, measurements, and inferences that we make about relationships among various observed variables
Hence, we can conclude that the correct match is (A) - (iii), (B) - (iv), (C) - (i), (D) - (ii).
Additional Information, Therefore, match with the appropriate process skills is as follows:
| Column I | Column II | ||
| (A) | What are the differences between seeds of a different type? | - | observing |
| (B) | Why do you think some seeds are growing more quickly than others? | - | hypothesizing |
| (C) | Draw a diagram to depict the changes in the seeds | - | communication |
| (D) | Based on your observation what do you think would happen if we double the amount of water? | - | predicting |
