1. Audience: The interests and needs of the audience should be considered first when choosing the theme content. For example, the theme of "dinosaur world" may be more suitable for children and teenagers, while the theme of "wonderful seeds" may be more suitable for adults who are interested in plants and ecology.
2. Educational purpose: The choice of theme content should also consider the educational purpose, that is, what kind of information and knowledge I hope to convey to the audience through the theme content. For example, the theme of "Dinosaur World" can let the audience know the biological characteristics, history and functions of dinosaurs in the ecosystem, while the theme of "Wonderful Seeds" can let the audience know the reproduction, growth and ecological value of plants.
3. Resource conditions: The choice of theme content should also consider the available resources and conditions, including funds, time, personnel and equipment. For example, the theme of "dinosaur world" may need more money and time to build scenes, make models and arrange exhibitions, while the theme of "wonderful seeds" may be easier to prepare and present in a shorter time.
4. Time background: The choice of theme content should also consider the time background and trend. For example, with the enhancement of environmental awareness, the theme of "wonderful seeds" may be more in line with the trend and social needs, while the theme of "dinosaur world" may be more attracted by traditional culture.
To sum up, the choice of theme content is a process of comprehensively considering various factors such as audience, educational purpose, resources and background of the times.
