Drug testing model Set, Students act as members of a hospital administration who are responsible for developing a substance-abuse prevention/drug testing program, Students will explore the chemical and physical properties of five illicit drugs and build a model for each drug
Set of nine models, showing the following stages. 1. Embryo 6 days old 2. 1st month of gestation. 3. Uterus with embryo in 3rd month of gestation.4. Uterus with fetus, in 4th month. 5. Uterus with fetus, placenta and umbilical cord.6. 5th month. 7. 7th month pregnancy.
Enlarged 20,000 times. The model shows delicate structure of an animal cell. Features organelles nucleus, endoplasmic reticulum, mitochondria, ribosomes respectively polysomic and Golgi apparatus. Also showing centrioles, lysosomes and fat vacuoles.
