Boardworks High School Science Mitosis Teacher notes This six-stage interactive animation shows how a cell divides by mitosis. Suitable prompts could include: Start: What type of cell might this represent? Stage 1: Where are chromosomes found? Stage 2: What must happen to chromosomes before the cell divides? Stage 3: How do the chromosomes get out of the nucleus? Stage 4: How are the chromosomes separated? Stage 5: What must happen after the chromosomes have been separated? Stage 6: How does each new cell compare with the original?
Boardworks High School Science Mitosis Teacher notes This ordering activity could be used as a review exercise on the stages of mitosis.
Boardworks High School Science Mitosis Teacher notes This drag and drop activity provides the opportunity for informal assessment of students’ understanding of what happens to chromosomes during mitosis.

Divide and grow Most animals and plants start off life as just a single cell, but grow to become adults containing billions and billions of cells. How does one cell become billions and billions of cells? The type of cell division that makes animals and plants grow is called mitosis . In mitosis, a parent cell divides into two identical daughter cells. These daughter cells divide in two, and so on. Mitosis is also the way in which old and damaged cells are replaced. mitosis parent cell daughter cells
Duplicating chromosomes A cell’s chromosomes are usually long, thin strands. Just before the cell divides, however, the chromosomes become shorter, thicker and more visible. They are said to condense . Each chromosome duplicates and becomes two strands, each one called a chromatid . The two chromatids are joined at the centromere . condensed chromosome centromere chromatid
