1st one is about magnetic field, we just separate the magnet from the dirt. and we just put a piece of magnet under the paper to separate the magnet and the dirt. you can see the process online.

2nd one is about the reaction for the mixture, i will send you the note about that.

3rd one is about the Microscopic and the cells, i will also send you the picture of the note, and i have the name of each cells you can google the image of it , and you can describe how the the cell looks through the Microscopic a little bit.

Thanks a lot.
