Animal gestation periods

I can use information to predict the gestation periods of different animals.

Lesson details

Key learning points

  1. Gestation is the period of time that an animal carries its offspring inside its body before giving birth.
  2. Patterns can be found in the gestation periods of different animals.
  3. Larger animals tend to have longer gestation periods (as they tend to produce larger offspring).
  4. Scientists can use patterns in their results to make predictions for further investigations.
  5. The gestation periods of different animals can be found out by observing them or by carrying out research.

Common misconception

Pupils may think that humans are not animals.

Explain that humans are animals and are part of the mammal group. Make clear the characteristics we have that mean we fit into this group.

Keywords

  • Animal - An animal is a living thing which moves and eats other animals or plants.

  • Offspring - Living things create offspring when they reproduce.

  • Gestation period - A gestation period is the amount of time an animal carries its offspring inside its body before giving birth.

  • Prediction - A prediction is a statement saying what you think will happen.

  • Research - To research something is to find out about it or investigate it carefully.

Give children plenty of time to think and discuss ideas when they are making predictions about gestation periods. You could enhance their discussion by plotting the information they have on a scatter graph and using that to help make predictions.
