Are you a good observer?

Are you a good observer?
In this picture there are two plants: a spike and a field bindweed. In spring it is easy to see
these plants in the woods. Look at them carefully. Can you tell the two plants apart? Are
you a good observer? Find out!
Plan of action:
√ Colour the plants according to the colour code and answer the related question.
√ Interpret the picture.
OBSERVATION
1. Colour the picture and choose the best answer for the question
COLOUR CODE:
SPIKE:
a. Colour the STEM yellow
b. Colour the LEAVES yellow
c. Colour the FLOWER yellow
d. Colour the SPIKE yellow
FIELD BINDWEED:
a. Colour the STEM green
b. Colour the LEAVES green
c. Colour the FLOWERS blue
QUESTION: You are an observer. Why did you colour the two plants?
a. Because observers are good at colouring pictures.
b. Because after colouring the plants, the picture looks more beautiful.
c. Because colouring the picture helps the observer to interpret it.
INTERPRETATION
What does field bindweed the to expose its leaves to the sun? How does it do it?
1. In pairs, use what you learned about stimuli and responses and try to answer these
questions. Prepare to explain the class.
2. Marc, Farah and Rosa are students in 2n ESO1. This is what they answered to those
questions. Which explanation is best? Use checklist 1 to decide.
Marc:
La correhuela es una planta que tiene los tallos muy flexibles, y para poder captar la luz se enreda a otras
plantas, porque sino estaría siempre a ras del suelo y no captaría bien la luz del sol. La correhuela cuando
nota a otras plantas inmediatamente se enreda y trepa eso lo hace gracias al tacto, uno de los estímulos que
puede percibir.
Farah:
La correhuela trepa por la espiga dando vueltas, el estímulo es el contacto, gracias al contacto de la
espiga la correhuela trepa dando vueltas, por que si no se caería y la luz le daría muy poco y en el suelo
se moriría.
Rosa:
La correhuela ha captado un estímulo y ha hecho una respuesta. El estímulo es que ha hecho contacto y
la respuesta es que se ha enrollado a la espiga ya que si no se enrollara el tallo caería al suelo y las
hojas, y la planta moriría porque no captaría la luz necesaria para la planta

3. Check your explanations in pairs. Use checklists 1 & 2.
