With this model your students will make paper models of an egg and sperm cell. They will then use their models to look at sperm cell and egg structure and to work through the steps of fertilisation and see how the nuclei fuse together in the egg cell. A great way to lead into IVF and other topics.
Covers: sperm cell structure, egg cell structure, acrosome reaction and haploid nuclei, diploid nuclei.
Includes full colour Powerpoint class presentation!
Takes about 20 minutes. Dimensions: sperm 17cm/6.5in long, egg 12cm/5in diameter.
Download includes: instructions, colour & mono templates, and Powerpoint file.
