Description

"Observing a Tree" Looking for Animals and Plants on Campus PPT Courseware 4

1. How to observe trees

1. General tasks: Observe in groups, and each group should try to observe different trees; the division of labor should be clear within the group, and everyone should have an observation task; describe a tree and complete an observation note.

2. Sub-task: Where on the campus does the tree we want to observe grow? How do we observe a tree in order? (from far to near, from the whole to the part)

3. Communication: What new observation methods can we use to observe new content? (Draw a simple diagram, measure the thickness of the trunk, smell the leaves, look at the fruits, make rubbings on the bark, pick up specimens, comparison methods...)

4. Compare: Can we remember things better than observations written in a book? (Write it down in simple words first, and organize it into observation notes after returning to the classroom.)

How to imprint tree bark

·Press the white paper tightly to the tree trunk,

·First press repeatedly on the paper with your fingers.

·Pinch the crayon flat and rub it on the paper.

·Dye the raised parts with color.

Group cooperation and communication to solve problems

1. In what order should we observe a tree? Why?

2. What new observation methods can we use to observe new content?

3. It is very difficult and inconvenient for us to record while observing. Is there any way to make our records more complete and faster?

Observation note requirements

1. Observe the time, place and group members of the recording

2. Records should be recorded in the order of observation

3. Records also require awareness of evidence, and it is best to affix the collected physical specimens.

Organize and exchange our observation records and think about how you would describe them?

1. Which trees were observed?

2. What do these trees look like?

3. What conditions do they need for their growth?

4. What are the similarities and differences between different trees?

extracurricular extension

1. Please choose a big tree you like and continue to observe it outside class to see how it will change? Record your findings in an observation notebook.

2. Prepare materials for the next class: pick up several common grasses (setaria), a camphor tree branch and its fruits and leaves.
