Joshua Heschel School, M
Program for Science Teachers
9th and 10th
(45 minutes each)
use interactive computer programs and visual aids to facilitate the learning of
Mitosis, gametes haploid, diploid, prophase, chromatids, synapsis, tetrad,
centromere, metaphase, anaphase, disjunction, telophase
Laptop computers with internet access
Chromosome beads from Carolina Science Supply
Magnetic board for teacher
Students must understand the
purpose and main stages of mitosis
Methods and Procedure:
Start with a 5 minute
review of the stages of mitosis by asking the students to guide you through
the stages. IP MAT – is a good acronym for the five main stages.
Divide the students into
groups of 4. Hand out the chromosome beads and allow the students five
minutes to demonstrate the process of mitosis using the beads
Start a discussion with
your class about the necessity of correct amount of chromosomes in each
What happens when a person
does not have 23 pairs of chromosomes?
( Answer- down syndrome)
How does the body ensure that
the next generation will contain the correct amount of chromosomes?
Once again, give the
students five minutes to arrange the beads and determine how meiosis takes
Review the process of
meiosis with your chromosome beads on your magnetic board and teach the
stages of meiosis.
Use interactive media for
the students to again visualize and practice the steps on their own laptops
worksheet for homework.
