I am/was in the same situation.... I think you should there is actually quite a lot to say about the little critters :D
I think a good topic would be rocks,what kind of rocks there are and write some information.

If it is a science speech, yes
a speech is good when the topic you've brought forward involves your audience and you present it in a simpler way as possible and lastly a speech is good when you understand your topic
A good speech topic is one that interests both you as the speaker and your audience. It should be relevant, timely, and have a clear purpose or message. Additionally, a good speech topic should be specific enough to be manageable within the time frame of the speech.
