Get a glass or plexiglass cube. Pick out your different cell parts (robosomes, nucleus…yadada.)

Once you have chosen all of the parts of the cell, pour a little of the jello(clear jello) stuff in the bottom of the cube and work your way up. I guarantee this will land an A++ for anyone. Its a little difficult, yet it will draw more attention than a piece of poster board with pasta glued to it.

-Something edible (such as a cake mix) and enlarge the model so that the whole class can have some when you are finished presenting (food always gets to kids.)

wood

cardboard

pipe cleaners and pompoms

different size bowls in side of eachother

thats all i can think of, hope i helped!
