Small scientific products are simple, and the production process is as follows:

Aluminum foil rocket, and the preparation materials: black cardboard, aluminum foil paper, red paper towels, handmade white glue or tape, pencils and scissors.

The specific steps are as follows:

1. Draw a rocket shape on the aluminum foil and cut it out. Tear a piece of red paper towel in half and stick it on black cardboard to make a fire-breathing shape. Then stick the aluminum foil rocket on the black cardboard to slightly cover some "flames" and stick some shiny stars around the rocket.

2. Paper tube rocket:

Preparation materials: scissors, glue or tape, pencil, toilet paper roll.

wrap the paper tube with colored paper, cut the paper with the length of toilet paper roll and wrap it. The colored paper is cut into a fan shape, rolled into a cone shape, glued and fixed at one end of the paper tube. Cut three small discs and stick them in front of the paper tube; Cut two small triangles and insert them on both sides of the paper tube. Finally, cut some pieces of paper and stick them on the inside of the bottom of the paper tube. The rocket to space is ready!

3. Hubble Space Telescope:

Preparation materials: toilet paper roll, aluminum foil paper, bamboo stick, cardboard and handmade white glue.

Punch holes in both sides of the toilet paper roll, pass them through with bamboo sticks, wrap the paper tube with aluminum foil paper, and glue it firmly with white glue. Cut two square pieces of cardboard, fold them in half and stick them on both sides of the bamboo stick. Our Hubble telescope is finished.

4. Big Dipper:

Preparation materials: blue or black cardboard, cotton candy and toothpicks.

The Big Dipper in the sky is spoon-shaped, which is the most easily recognized. It is also an important group of stars to indicate the direction and know the constellation. We strung toothpicks and marshmallows into the shape of a big dipper, stuck them on cardboard, and spread a few scattered stars around them as decorations.
