The pictures are not mine.
Please don't sue me because my students loved your pictures. The pictures were very useful in their learning of Science and in English too.
This is a presentation made and presented to my Thai students -- non-native English speakers.
This PowerPoint can be edited to accommodate what you want to be removed or inserted.
Thanks for downloading and not suing me :D
