1 The GlaSS-house grEEnhouse 3 rd cycle of primary school LES

2 Objectives for the task  This LES presents various directed activities in order to initiate the students, through the living world to the use of measurement instruments as well as to laboratory work techniques.

3 Validations… What was done… 1 st time: October 2010… Fresh and new!  Upgrade of previous knowledge;  Essential needs of plants;  Initiation to measurement instruments (scale, graduated cylinder);  Initiation to a separation process: filtration;  Introduction of tropisms and photosynthesis;  Discovery of coloured pigments in plants.

4 Prerequisites:  Technical capsules about:  The scale;  the graduated cylinder;  filtration.  Context:  Presentation of the request for information.

5 Request for information

6 Activity 1: Prerequisites  Upgrade of knowledge:  Differences between living and non living organisms;  anatomy of plants;  role of roots, stem and leaves;  needs of the plant.

7 Validations…

10 Activity 2 The objective, to distinguish between:  Photosynthesis;  Respiration; Respiration;  Evapo-perspiration. Using examples, videos and demonstrations, show the students that plants feed themselves, breathe and perspire.

11 Activity 3: Tropisms  Distinguish three types of movement in plants:  Phototropism;  Hydrotropism;  Geotropism.

12 Activity 3: Tropisms

14 Validations… Phototropism

15 Validations… Hydrotropism

16 Validations… Geotropism

17 Activity 4: Photosynthesis without chlorophyll, useless!  Initiation to laboratory work techniques;  Initiation to the experimental process by directed lab;  Discovery of laboratory instruments;  Extraction of chlorophyll;  Initiation to diagramming.
