Write down the essential elements for seed germination.

Arun germinated some seeds. He measured the height of one of the seedlings every two days. He wrote down its measurements.

Day $2: 10 \mathrm{mm}$, Day $4: 15 \mathrm{mm}$, Day $6: 25 \mathrm{mm}$, Day $8: 35 \mathrm{mm}$, Day $10: 40 \mathrm{mm}$

Draw a line graph of Arun's results.

Present Arun's results in a table. Remember to give each column a heading.

Observe the bar graph carefully to answer the question.

Class $5$ investigated germination. They put seeds on damp cotton wool and placed them into plastic bags. They then put the plastic bags in different places. They checked the seeds after three days. This is the bar chart of their result.

What do the result tell you about the condition that seeds need to germinate?
