Text of the walking dictation

Seeds are the product of angiosperm plants sexual reproduction.

Seeds contain a dried, folded new plant called seedling

Seedlings are protected by a cover.

Seeds are carried away by the wind or by animals.

If they find water the plants within unfold and start to grow.

The parts of the seedling are root, stem and one or two small leaves called cotyledons.

Investigation 1: What’s in a seed?

1. Walking dictation

Make groups of 4

Within each group, each student chooses a number from 1 to 4, without repeating

Students with number 1 go to the teacher

The teacher dictates a sentence and the students try to memorize it

Students return to their group and dictate the phrase to their fellows

The rest of the group tries to write the sentence

Students with number 2 go to the teacher for the following sentence, and so on…

a. Write the text of the walking dictation

b. Write the text again from the corrected version in the blackboard

Seeds are the product of angiosperm plants sexual reproduction.

2. Draw the inside of a seed as you imagine it in the square on your left

3. Now peel a seed and draw it again in the square in the middle. Ask for a binocular

magnifier if you need one. Try to put the next names in the correct place:

Seedling, Root, stem, cotyledons (leaves), tip, cover

4. Let the seed grow for some days and draw it again in the square on the right side

(writing the names again).

5. Think of a method to know the amount of water a seed takes in the germination and

write a list of at least 5 steps.

2. ………………………………………………

3. ………………………………………………

Question Can plants react to the environment?

Hypothesis (Complete the sentences with the words in the box to write 3 hypothesis)

Plants Can/can’t react to light direction/gravity/darkness moving/ growing/ doing …….…….

1. ………………………………………………………………………………………………………………….………………….

2. ……………………………………………………………………………………………………………...……..……………..

3. ………………………………………………………………………………………………………………….…………………

Experiment (Draw a picture for each material and step)

Material

7 days seedlings boxes pencil, pots cotton or absorbing paper

Steps

1. Take 4 pots and put some cotton or absorbing paper in their bottom

2. Put ten seedlings in each pot

3. Put a pot with the seedlings in a closed box

4. Put a pot with the seedlings in a closed box with some holes in one side

5. Take a pot and put the seedlings upside down

6. Wait a week to see what happens to the seedlings

Investigation 3: Watching an angiosperm flower

1. Complete a card with the information from your observations with the binocular

magnifier and use it to write a description of the flower of an angiosperm species.

Scientific and common name of the plant: ……………………………………...……………………………………

The sterile part of their flowers consists in:

number color equal/different name of the piece

Drawing/glued pieces

A calyx made of

A corolla made of

The fertile part that consists in:

number color equal/different name of the piece

Drawing/glued pieces

An androecium made of

A gynoecium made of

Investigation 4: Herbarium sheet

Now we worked on differences among plant groups is time to find two plants near your

home and make an herbarium sheet with each one.

A herbarium sheet is a DIN-A4 with a plant:

o as complete as possible

o dried

o taped

o Labeled with the name of

parts observed: root, stem, leaves, spores, flowers, seeds,

fruits…

We will use as title the scientific name of the plant and its

family. We can also write its common names in Catalan,

Spanish and English. Finally we are going to

You can identify the most common plants of Catalonia

using the web flors de catalunya

Give to a fellow your herbarium sheet for correction. Use the next rubric:
