? Documentary introduction
If, like me, you always regret missing the scenery in front of you many times, then don't miss this BBC documentary I introduced. It was shot in Kew Garden of the Royal Botanical Garden. Let's walk into the Royal Botanical Garden.
Royal Botanical Garden, Kew Garden.
We change the rhythm of time and step into their endless dynamic world. We change the viewing scale to understand their interaction with insects. We can analyze the way they communicate, through color, smell and even heat. We will find that fungi are not the enemies of plants, but their basic allies. -Plant Kingdom.
Today, we will introduce an episode of "Solving the Secret".
insectivorous plant
Mao Gao in the picture below is an expert at catching insects. Have you ever watched plants catch insects at close range? Do you know how they catch insects? How do they "enjoy" these prey?
Hairy ointment
I believe everyone is familiar with this carnivorous plant. Yes, it is the flytrap. But how can we touch its trap? Are there any insects that can escape? Do you know how long it takes to fully digest this delicious meal?
flytrap
The picture below shows the carnivorous plants living in lakes and ponds-Utricularia, also called Zhacao. Do you know how fast it catches insects? How exquisite is its insect catching structure?
Utricularia, also known as brake grass.
The film shows us a different world in the eyes of insects through special lenses.

In addition, there are the relationships between insects and plants, fungi and plants, and so on. I won't destroy it here.
Knowledge expansion
The reason for watching documentaries is that the contents of documentaries are true and scientific, which requires the viewers to have a certain knowledge reserve in order to better understand them. And it can give children an opportunity to expand their learning. Good audio-visual works can arouse children's interest in learning and research. Let's talk about what we can do to expand our knowledge according to the topic.
mathematics
For young children, you can know in advance what you have not learned. If children have learned this knowledge when watching movies, they may wish to sort out the knowledge.
1. Time: Take the textbook published by People's Education Press as an example, children in the first grade of primary school will start studying time. Time unit is an important part of reading and writing time. Most children know the units of time: year, month, week, day, hour, minute and second. This is a new time unit: milliseconds. How short is the millisecond? Are there any other time units?
2. Percentage: the percentage of the sixth grade of the textbook published by People's Education Press. What do you mean by percentage? What's the point? What's the difference between percentage and score?
3. Numbers: It is very important to understand numbers in the whole primary school. Digital learning is also a difficult point in children's learning process, so we must pay attention to it and check the missing parts for children in time.
4. Multiplication: the content of the fifth grade of primary school published by People's Education Publishing House.
5. Length unit: the conversion method of kilometers and meters.
English
1. Children in the enlightenment stage: You can master some high-frequency words appearing in movies or common words in life.
High-frequency words: flowers and insects. ...
Color classification: white and white, pure blue and pure blue. ...
Body type: nostrils, eyes and eyes. ...
2. For older children, you can keep some professional words, such as pollen, ultraviolet rays, pedal petals and fungi. ...
biology
1. What parts are flowers made of? In fact, I have learned this part of knowledge in science class in primary school.
2.DNA: Children in lower grades can have a general understanding with simple methods such as models and pictures.
3. What are the parts of plants?
4. What are the characteristics of insects?
handwork
1. Make a leaf painting. From leaf selection, pattern design to production, cultivate children's practical ability and creativity.
2. Make leaf specimens. There are many details to pay attention to in the process of specimen making, which requires children to do their homework in advance and be very careful and considerate in the process of specimen making, so as to have a successful specimen, which is a good ability expansion for children in middle and lower grades.
geography
Many place names such as Amazon jungle and Himalayas are mentioned in the film, and children can be taken to study the topography, climate and plants suitable for growth in various places. This is a huge workload expansion project, not only to do a lot of data reading, but also to screen useful information, records and so on.
physics
Vibration knowledge. Definition and classification of vibration, etc. This part of knowledge is difficult and suitable for senior primary and middle school students.
chemistry
The invention and use of microscope. There are many microscope toys on the market now, which can be used by children in their usual observation and study to cultivate their curiosity and inquiry spirit.
art
Draw a picture with the theme of "the garden in your heart", design your own small garden, and then say why? Cultivate children's creativity, imagination and language ability.
science
1. If children are interested, they can make an observation report on plant growth by themselves. From this process, we can understand the scientific research spirit of scientists, cultivate persistent character and cultivate observation ability.
2. What is the 3D technology mentioned in the film? What is the principle? How does it help us?
These are just some examples I have given, and there are many aspects that parents can explore, but when expanding, they must start from the points that children are interested in, and don't force children to expand their knowledge.
