Lesson Title: Today we are learning about
What are stem cells and how can we use them?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Most types of animal cell differentiate at an early stage. As an organism develops, cells differentiate to form different types of cells. As a cell differentiates it acquires different sub-cellular structures to enable it to carry out a certain function. It has become a specialised cell. Students should be able to explain the importance of cell differentiation. In mature animals, cell division is mainly restricted to repair and replacement. A stem cell is an undifferentiated cell of an organism which is capable of giving rise to many more cells of the same type, and from which certain other cells can arise from differentiation. Students should be able to describe the function of stem cells in embryos, in adult animals and in the meristems in plants. Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells. Stem cells from adult bone marrow can form many types of cells including blood cells. Knowledge and understanding of stem cell techniques are not required. Treatment with stem cells may be able to help conditions such as diabetes and paralysis. In therapeutic cloning an embryo is produced with the same genes as the patient. Stem cells from the embryo are not rejected by the patient?s body so they may be used for medical treatment. The use of stem cells has potential risks such as transfer of viral infection, and some people have ethical or religious objections. (WS) Evaluate the practical risks and benefits, as well as social and ethical issues, of the use of stem cells in medical research and treatments.

AFL/Key Questions:

At what stage of an animal cell's life cycle does it differentiate?
Most types of animal cell differentiate at an early stage.
What happens during cell differentiation when an organism develops?
As an organism develops, cells differentiate to form different types of cells.
What happens to a cell during differentiation to become a specialised cell?
As a cell differentiates it acquires different sub-cellular structures to enable it to carry out a certain function. It has become a specialised cell.
Why is cell differentiation important?
Cell differentiation is important because it causes cells to become adapted for a particular function. This makes the cell specialised.
In mature animals, what is cell division mainly used for?
In mature animals, cell division is mainly restricted to repair and replacement
What is a stem cell?
A stem cell is an undifferentiated cell of an organism which is capable of giving rise to many more cells of the same type, and from which certain other cells can arise from differentiation.
What is the function of stem cells in human embryos?
Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells
What type of cells can be produced from bone marrow stem cells?
Stem cells from adult bone marrow can form many types of cells including blood cells
What conditions are stem cells used to treat?
Treatment with stem cells may be able to help conditions such as diabetes and paralysis.
What is produced in therapeutic cloning?
In therapeutic cloning an embryo is produced with the same genes as the patient.
Why can stem cells from embryos useful in medical treatment?
Stem cells from the embryo are not rejected by the patient?s body so they may be used for medical treatment.
What are the dangers of using stem cells for treatment?
The use of stem cells has potential risks such as transfer of viral infection
What are the ethical issues surrounding the use of stem cells?
harm/death to embyro, un natural, un godly

Starter Activity	Differentiation and Challenge question/task
Students to copy and complete the keywords. Teacher reveals missing letters; Students correct mistakes; Discuss the scientific meanings of the words. Students to write down the definitions of the most important / new keywords. Discuss the 'Memory Anchor'. What does it show? How does it relate to the what we are learning about today (title)?
