Task 4.1

Move around the room and use the posters available to “rescue” your orphaned joey.  For each species, use the three different graphs to get three different predictions for the age of your joey.  Record these predictions in the appropriate column on your Orphaned Joey Card.  Once you have done this, you will be able to decide which species your joey is and how old it is. Complete the table at the bottom of your Orphaned Joey Card.

Once this is completed, collect a VET CLINIC card. Now use the information about your species from the Growth Charts to complete the first table about the future growth of your joey. Follow these steps:

1. Fill in the grey row in this table with the relevant information

2. Go to the next age point on the Growth Charts for your species. For example, if your joey is 23 days old, then your next age point is 40 days.

3. Fill in the way your joey will grow over the next 4 age points using the data from the Growth Charts.

Now you have to work out what to feed your Joey in order to keep it alive and healthy at each of these age points. Use the information about feeding you will find at Feed Chart for Different Kangaroos to decide the correct type of milk formula as well as how much to use for your joey and how many feeds it will need per day.

If you have saved your joey and have time to save another, see your teacher.
