Suggestions for small science assignments are as follows:
1. Make a Windmill: Use materials such as paper cups, bamboo sticks, and glue to make a windmill. which can turn with the wind.
2. Make a Volcano: Use red clay, white gypsum, and paint to create a realistic volcano model.
3. Make a Simple Solar Water Heater: Use plastic bottles, black tape, insulation materials and other materials to make a simple solar water heater.
4. Make an electric car: Use materials like batteries, wires, and small motors to make an electric car that can drive.
5. Make a Simple Phone: Use two paper cups, a piece of cotton thread, and other materials to make a simple phone.
6. Make a dialsolar: Use a disk, pen, ruler, and other materials to make a sundial that can show the time.
The above are some suggestions for a little scientific hand-making. You can choose suitable materials and production methods according to your own interests and hobbies, and use your creativity and imagination.
Characteristics of handmade products:
1 Uniqueness: Handmade works are unique and no two works are the same . This is because there are many factors involved in the production process, such as materials, processes, techniques, etc., which will affect the final result.
2. Customization: Handmade works usually have personalized features. Indeed, the producer will create according to his own preferences, experience and creativity, so that the work can show aa unique personality and style.
3. Flexibility: In the manual production process, the producer can adjust the production plan and materials at any time as needed, which provides great flexibility. At the same time, handmade pieces can also be customized or modified as needed to meet different needs.
The wind speed is different, and the angle and number of blades of the wind wheel are different.
1. Wind speed is the most important factor affecting the rotation speed of the windmill. The higher the wind speed, the faster the windmill spins.
2. The angle and number of wind turbine blades will also affect the rotation speed. Generally speaking, the larger the blade angle, the faster the accelerated wind speed and the faster the rotation speed and the higher the rotation speed. the number of blades can increasement wind power. The supporting area of the wheel increases its rotation speed.
