Grammar Check for a Sentence About Baby Jellyfish for 8-Year-Olds

The sentence you provided is:

"Baby jellyfish stick to a rock and turns into a polyp, which later makes many little jellyfish."

Let's check the grammar step by step:

• Subject and verb agreement: The subject is 'Baby jellyfish', which is plural (more than one baby jellyfish). If the subject is plural, the verb should also be plural.
• In the first part, you wrote 'stick', which matches the plural subject, so that is correct.
• In the second part, you wrote 'turns', which is singular. Since the subject is still 'baby jellyfish' (plural), it should be 'turn' instead of 'turns'.

Corrected sentence:

"Baby jellyfish stick to a rock and turn into polyps, which later make many little jellyfish."

Also, note that one baby jellyfish turns into one polyp, but since many baby jellyfish are involved, we use 'polyps' and 'make' in plural form.

So, the final corrected sentence is:

"Baby jellyfish stick to a rock and turn into polyps, which later make many little jellyfish."
