The 2024 Paris Olympics came to a successful conclusion!
Looking back at the Olympic Games that China won
The first gold medal, Huang Yuting and Sheng Lihao of the Chinese team
Excellent performance in the 10m air rifle competition
Still exciting.
In air rifle competitions, athletes must not only consider
The scoring criteria for the competition, and more importantly, the bullet
Precise control and prediction of the launch process.
Every detail is consistent with scientific principles
Closely related.
For example, the firing of a bullet from a gun involves a conversion of energy.
and force ; the bullet needs to be considered during flight
The effects of air resistance and gravity ; by regulating breathing,
Heart rate and muscle tension improve design stability and precision is the application of biological knowledge.
It can be seen that scientific knowledge should not be underestimated.
Next, let's look at KS3 Science
What is the content of the course? What are the difficulties?
KS3 Science
KS3 Science (Key Stage 3 Science) is
Part of the UK National Curriculum , designed for
Designed by students aged 11-14 .
It is the first part of the secondary school stage.
Typically includes Years 7, 8 and 9 courses.
KS3 science not only emphasizes biology and chemistry
And the knowledge points of physics ,
Great emphasis is also placed on experimental skills.
Must-learn knowledge points
1. Biology
- Cell structure and function
- Genetic basis
- Human body systems (such as circulatory system, digestive system, etc.)
- Ecology and Environment
- Growth and development of plants and animals
2. Chemistry
- Properties and changes of matter
- Atoms and molecules
- Chemical reactions (such as acid-base reactions)
- Mixtures and dissolutions
- Separation and purification of substances
3. Physics
-Force and motion
-Energy (such as electrical energy, thermal energy, etc.)
-Light and Sound
-State of matter (solid, liquid, gas)
-Simple circuits and current flow
Important Skills
1. Experimental skills
- Use your understanding of scientific knowledge to make predictions
- Ability to select the most appropriate method for scientific investigation
- Use appropriate equipment and materials correctly
- Observe and measure using different survey methods
- Evaluate the reliability of the method and make possible recommendations
2. Data Analysis
- Apply mathematical concepts and calculate results
- Present results and data in an appropriate manner
- Interpret , predict and hypothesize relevant data
3. Scientific Inquiry
- Propose scientific questions or hypotheses based on existing knowledge
- Develop experimental methods to test hypotheses
- Evaluate the validity of assumptions
Difficulty in learning
1. Understanding of scientific concepts
Scientific concepts are often abstract in nature . The complexity of these concepts makes it challenging for students to apply and understand them in real-world situations.
2. Scientific Academic Vocabulary
In science courses, students will be exposed to many professional terms . Whether they can understand the questions and express their ideas with correct professional terms is the key to scoring.
3. Integration and application of knowledge
Students need to integrate knowledge from different disciplines and apply it to practical problems. Using multidisciplinary knowledge to solve problems is a test of students' flexibility of thinking and proficiency in knowledge.
4. Mastering experimental skills
Experiments are essential in science courses, which requires students to master correct scientific research and experimental methods .
5. Data Analysis and Understanding
Data analysis involves the organization, interpretation and evaluation of experimental results , and students need to have certain mathematical skills and critical thinking ability.
