Have star shapes cut out for your students to decorate. They can use crayons, markers, paint or glitter. While they are decorating, talk about the stars, such as how many are in the sky or how bright they shine. Once the children's stars are dry, glue Popsicle sticks to the back. Have the kids hold the stars while you sing "Twinkle, Twinkle Little Star" with them.
Gather enough empty paper towel rolls for each student in your class. Let each student choose a sheet of construction paper to glue around the tube to give it color. If you want, they can draw on the construction paper first to decorate it. Then you or the students can cut four 2-inch slits on one end. Slide two triangle pieces into the slits to create the base of the rocket (the triangles also should have slits so they fit together). Create cones with circular pieces of construction paper and glue them on the top of the rocket. Further decorate the rocket with stickers or other items.
Have each student bring in a tin can, then discuss what constellations are and the names of major ones. Have the students pick their favorite constellation and draw it with a marker on the closed end of the can. Then the teacher can put holes in the cans with a hammer and nail for each necessary star. Shine a flashlight through the cans to show the students how to see their homemade constellations.
You will need a coffee filter for each student as well as washable blue and green markers. Flatten the coffee filter and have the students draw what Earth looks like from space to the best of their ability. Then let each student drop a little water over the coffee filter so the colors bleed into each other. After the filter dries, each student can glue it onto black construction paper. If you want, add sticker stars or drop glitter onto glue spread on the black paper to create a space effect.
