This is a LARGE file... Why? I made this on Microsoft Publisher with the dimensions of 28"x22". It is a picture with a LARGE number of pixels (8400x6600) so that you can buy this image and then use it on a 'create your own' poster website. Upload the image and set the dimensions of your poster to 28"x22", then buy! Your poster will look great with clear images because of the original image was made to be large.
This is an image I made using multiple pictures to illustrate the exothermic oxidation-reduction reaction of thermite. A description of what takes place during the reaction is also on the picture.
Great for putting up on walls in any science classroom to spark students' interest in science.
Not only is it a great wall picture, but science teachers can actually perform these reactions as a demonstration to students!
