Botanical explorer activity

Do you remember the activity when you were a botanical explorer at Gimnasio Los Arrayanes Gardens?

 

So, the following example are the results when two students (Martín and Paula) did the scientific exploration: they observed, identified, described and classified the different plants in the gardens. They completed the following chart:

Chart 1 Statistical worksheet show the classification and numbers of each plant species.​

Multiple Choice

Look the Chart 1, which group of the plants was observed MORE times in the botanical exploration?

• Angiosperms

• Gymnosperms

• Ferns

• Mosses

Multiple Choice

Look the Chart 1 again, which group of the plants is observed LESS times in the botanical tour?

• Angiosperms

• Gymnosperms

• Ferns

• Mosses

Multiple Choice

How many flowers-producing plants (angiosperms) were observed on the botanical exploration?

• 9

• 39

• 57

• 10

Multiple Choice

How many SEED-producing plants (angiosperms and gymnosperms) were observed on the botanical exploration?

• 12

• 39

• 57

• 10

Multiple Choice

How many SPORES-producing plants (ferns and mosses) were observed on the botanical exploration?

• 12

• 39

• 57

• 36

Then, Martín and Paula drew some structures (flowers, fruits, cones, capsules, sorus, leaves) of each plant according to their type (angiosperm, gymnosperm, fern or moss), and create the following Chart 2:

 

Remember that:

·      Angiosperms have flowers and fruits.

·      Gymnosperms have cones.

·      Ferns have sorus.

·      Mosses have capsules (sporangium).​

Multiple Choice

Martín and Paula found nine (9) plant species. But, one of the data is WRONG. Which? And why?

• The species #3, because it isn’t possible for a plant to have a flower and fruit at the same time.

• The species #4, because they didn’t draw a flower on this plant.

• The species #5, because it isn’t possible for a plant to have a flower and cone at the same time.

• The species #9, because they didn’t draw a flower on this plant.

Multiple Choice

The species #1 is an angiosperm, because Martín and Paula drew

• flower and fruit

• Sori

• Cone

• Capsule and sori

Multiple Choice

The species #2 is a gymnosperm, because Martín and Paula drew

• flowers and fruits

• Sori

• Cone

• Capsules and sorus

Multiple Choice

The species #7 is a moss, because Martín and Paula drew

• flowers and fruits

• Sori

• Cone

• Capsules

Multiple Choice

The species #7 is a fern, because Martín and Paula drew

• flowers and fruits

• Sori

• Cone

• Capsules

Plants and their characteristics

Multiple Choice

The living thinks need different things to live. For example, the animals need water, food, shelter and air to live. But the plants need to live

• Soda, sunlight, soil and air

• Water, play, soil and air

• Water, sunlight, soil and cotton

• Water, sunlight, soil and air

Multiple Choice

The parts of the plants have different functions. For example, the seeds or spores are very important to reproduce. So, the roots move the water and nutrients from the

• leaves

• soil

• air

• sunlight

Multiple Choice

Other parts of the plants, like the stem is very important, too. It carries water and nutrients from the roots to the

• leaves

• soil

• air

• sunlight

Plants and fungi

Fungi are different from plants, because fungi cannot produce their own food, they don’t have leaves, flowers, fruits and roots, but for example the mushrooms have cap (1), gills (2), stalk (4), hyphaes (5) and mycelium parts, and reproduce with spores.

​

Fungi kingdom

Multiple Choice

The part of the mushroom where the spores are formed is called

• cap

• gills

• stalk

• spores

Multiple Choice

Similar to the stem in a plant, the name of the fungi part in number 4 is a

• cap

• gills

• stalk

• spores

Rocks

Rocks have different properties. A property is the hardness.

For example, chalk is soft and crumbles easily into powder. Marble is hard and waterproof.

Friedrich Mohs decided that if he used one rock to scratch another, he could see which was the harder rock.

Hard rocks leave scratch marks on softer rocks. The following chart shows the Mots’ Hardness Test Scale in different examples:

Moh's hardness test

Multiple Choice

If you compared Quartz and Obsidian using the Mohs’ Scale of Hardness, which rock would have a scratch on it?

 

The rock that would have a scratch is the

• Chalk

• Quartz

• Obsidian

• Diamond

Multiple Choice

If you compared Slate and Sandstone using the Mohs’ Scale of Hardness, which rock would have a scratch on it?

 

The rock that would have a scratch is the

• Diamond

• Slate

• Sandtone

• Granite

Not all rocks are the same. Rocks can be one color or have different colors in them. Some are rough, and some are smooth. Some are shiny, and some are dull. Rocks are made up of small parts called grains. When the grains are very small, we say the rocks are fine-grained. When the grains are larger, we say the rocks are coarse-grained. Sometimes, rocks have shiny crystals in them. Scientists who study rocks at the surface of the Earth are called geologists. Geology is important because it helps us understand how Earth came to have its present shape and form.​

Multiple Choice

Why is important the geology?

• Because they help us to study the living things that live inside the soil.

• Because they help us to study the plants and fungi.

• Because they help us to study the soil, rocks and how Earth came to have its present shape and form.

• Because they help us to study how Sun came to have its present shape and form.

Multiple Choice

Rocks can have many characteristics. They can be shiny or dull, big or small, and they can be rough or

• smooth

• diamond

• transparent

• soft
