Week 2 Classification of Organisms and two Thinking Science Lessons
Task 1 Recall the characteristics common to all organisms
Task 2 Snails, slugs, slaters, worms and caterpillars - observation and classification
Each student uses the binocular microscope and hand lenses to make and write detailed observations of at least one of the living invertebrates that you have brought to class. Write these in your science book.
In groups of four students
In groups of four students
- exchange observational notes with each other by taking turns reading around the group, comparing each others to your own observations. Add to the observations until you have an agreed set of observations for the group of four students.
- Write your common observations on the papers provided.
- Within your group agree on characteristics that are similar and different to sort the four organisms and construct a dichotomous key. This key shows the relationships between these four organisms, based on the observations of your group.
- Each student draws the dichotomous classification key into their science book.
- Compare your group's classification with other groups.
- 1.Did the other group place all the organisms into the same group as you did? Why or why not?
2. How might this activity change if both groups spoke different languages?
New Dolphin species discovered in Melbourne
Discuss how the new species was identified and how information about the new species was communicated with other scientists around the world.
Ask students what they would call a new species of animal if they found one.
