For our science lesson today we are continuing with our learning journey on the classification of living things. We will be learning about the relationship between a species and the environment it lives in and how this can affect the evolution of a species. We will also learn about selective breeding crops and animals and consider why humans may do this.
Don't forget to use your knowledge organiser, which can be found below. Particularly use the vocabulary section to help you understand words such as adaptation and evolution.
Firstly, use the link below to access the BBC Bitesize pages on adaptation, evolution and inheritance. Watch the associated videos and complete the activities contained in these pages to help your understanding.
Now read the webpage link below, which explains more about selective breeding.
As you are reading, consider why humans have chosen to selectively breed crops. What benefits can this bring? Remember, this is not a recent invention, selective breeding of crops has been going on for as long as humans have been farmers. Why would farmers have have selected certain plants to provide seeds to plant for next year?
Humans have also selectively bred animals too, often for food, but also for specific jobs. Animals were vitally important for humans, and it is only relatively recently that motor vehicles have taken over many of the jobs that animals did.
Now take some time to do some research of your own. Consider different types of animals, for example dogs and horses, and research the different jobs that these animals have done or currently do. Think about why humans would have selectively bred these animals in this way. What adaptations do they have that makes them suitable for a specific task? Write a short paragraph to summarise your research and we would love to see some of your research, so if you can, ask a carer to email your work in.
