Steps to make an aerospace rocket model:
1. First of all, we need to prepare the materials and tools, a drink bottle, colored paper, a pair of scissors, a piece of aluminum foil, corrugated paper and paint.
2. Cut off the bottom of the drinks bottle, leaving a section of the neck of the bottle, about 20cm, like the body of the model rocket, and make a hole in the section near the neck of the bottle. .
3. Use corrugated paper to create a pointed cone shape and place it over the mouth of the drink bottle as the head of the aerospace model.
4. Use paint to color the drink bottles and corrugated paper used as the base support of the aerospace model. The rocket head can be wrapped in foil without applying paint.
5. Cut four openings at the bottom end of the beverage bottle, place thecorrugated paper on it, then stick the beans as decoration and add color.
6. Add a tail to the rocket model. You can tie it into a bundle with thin strips of paper and insert it like a tail. A stunning space rocket model made of drink bottles is ready. The overall appearance doesn't particularly resemble an aerospace model.
A little craft science for ages 7 to 12
Making handmade models is a stimulating and creative craft art. Here are the steps to follow to make handmade models. General steps:
Determine the model type: Choose the model type according to your interests and abilities, such as planes, cars, ships, etc.
Obtain Model Materials: Obtain the required model materials, such as cardboard, plastic boards, wood, metal wires, etc.
Make a sketchModel: Make an accurate model sketch based on the type of model chosen to determine the dimensions and proportions of each part.
Cutting out model parts: Use scissors, blades and other tools to cut model parts according to the model sketch.
Assemble the model: Assemble the model parts according to the model sketch, and use glue, tape and other tools to stick the parts.
Detail processing: Once the model is almost complete, details are processed, such as painting, labeling and detail lines.
Done: Complete the manual production of the model.
Making handmade models requires patience and skill. If you are a beginner, you can start practicing with simple patterns. At the same time, referring to some production tutorials and videos can also help you improve your production skills.skills and practical experience.
The period from 7 to 12 years old is a special period when children are simply curious and need to acquire various scientific knowledge and exercise their brain and practical abilities. We can make crafts or do scientific experiments, so that children can not only acquire knowledge, but also exercise their abilities. So, what are some handmade science products that are suitable for this age group?
1. Small scientific craft production for 7 to 12 year oldsName of production: automatic water dispenser
The materials are precisePreparation: a bottle of Coke 1000 ml, a bottle of mineral water and a plastic tube 0.5 cm in diameter and 40 cm long.
Production steps: (1) Drill 2 holes with a diameter of 0.5cm in the cap of the mineral water bottle.
(2) Dividesz the 40cm long plastic pipe into a 30cm long positioning water pipe and a 10cm long water supply pipe, and insert them respectively one of the longest is inserted into the bottom of the bottle, and the other is inserted into the neck of the bottle.
(3) Take 10 cm from the bottom of the Coke bottle, cut it into a basin of water, and drill a hole of 0.5 cm in diameter in the upper and lower parts of the basin. 'water.
(4) Insert the water supply pipe into the bottom hole and insert the positioning water pipe into the bottom hole.
(5) Use a wire to connect the water supply bottle and the water basin.
How to use:
1. Unscrew the cap of the water supply bottle, fill it with water and tighten it, then pour in an appropriate amount of water in the water basin.
2. When the water in the water basin is lower than the water level, thewater in the water supply bottle flows out. When the water in the catch basin is higher than the water level, the water supply bottle will stop supplying water.
2. How to carry out small science experiments for elementary school studentsPreparation materials: glass or jar, water, dropper, shaving cream, food coloring
Experimental steps: 1. Pour water into the glass, about an inch from the rim.
2. Carefully add a layer of shaving cream to the water, being careful not to make it too thick, otherwise the wait will take a long time. The shaving cream represents the clouds and the water the atmosphere.
3. Add a few drops of blue food coloring to the shaving cream. The weight of the food coloring will start to push the shaving cream and it will fall into the water in the glass! It looks like rain.
3. The great importance of small scientific experimentsicals for children1. Experiments satisfy children's desire for knowledge and curiosity. For children, curiosity is natural and the experiences themselves are full of unknowns and surprises. Through experimental operations, they can not only satisfy their curiosity, but also cultivate a dedicated spirit of exploration.
2. Cultivate children's ability to observe and remember. Scientific experiments are very rigorous and there is no room for carelessness or carelessness. Observation is the first step. In addition to observation, a strong memory is essential.
3. Cultivate a sense of rules. The purpose of experience is to find the rules of reaction and synthesis of things through failure and exploration, and then to understand their essence. The laws of things are objective and independent of personal will. Through experiences, thought is activated and consciousness iscultivated. Effectively combine theory and practice.
