Science
Welcome to our term 4 science topic. This term we are exploring animals including humans.
How do humans change during their lifetime?
For your first activity, you could draw and label the main stages of human growth using a timeline. You could use this to explain the main stages of human development to someone.
How long are the gestation periods of different animals?Gestation is the period of time that a mammal carries her offspring, or babies, inside her body before giving birth. The length of gestation is different for each type of mammal. Analyse the table below. What do you notice?
Gestation period of humans compared to other animals can be found on many websites, including: http://www.vaughns-1-pagers.com/biology/gestation-periods.htm http://www.factophile.com/show.content?action=view&pageid=6
You could either create their own table showing similar information to the one above, but clearly ordering the animals according to the lengths of the gestation periods, or they could have a copy of the table above and number the animals according to the length of the gestation periods.
Is their a relationship between the mass of adult animal and the length of the gestation period?The children could either research the mass of adult animals or use the information below.
You could either draw or use a piece of software to produce a scatter graph; plotting the gestation period of an animal against its mass. http://nces.ed.gov/nceskids/createagraph/default.aspx
The graph will probably look similar to the one below: |
