First we dressed for India - I used eyelash glue and rhinestones to put the girl's Bindi's on. We just got scarfs and jewelry we had - we used white muslin for the turban.
To make the diorama we used shoe boxes (oversized -like for boots works best), fiber fill for clouds, glue gun to attach it, newspaper and tape to form and attach the mountains, and paint.
We then painted the background of the shoebox sky blue, then formed various size mountains with the newspaper (if you open up a sheet of newspaper and then grab it at the middle and pull the rest down it will make a "peak" then you can form it around that). We taped them in and then painted them and added the clouds at the end with the glue gun.
To make the model for the Science, we just used cardboard from a box that I cut into rectangles, glue gun to attach everything, cracked eggs I washed and dried, a horse/baby they colored, and air dry clay to model the worms for the fragmentation.
