"Ant" animal PPT

Part One: Observing the Life of Ants

Let's go to the campus and observe ants. Bring some bread crumbs and sugar as food to attract ants. Bring a magnifying glass to observe the ants' bodies.

Observations:

Ant body structure

how to find food

How do you react to food?

how to exchange information

How ants cooperate to carry food

How to march in line

The ants are so small that they cannot be seen clearly through the bottle; the ants on the white paper are crawling everywhere, and it is difficult to observe them. We can do this:

Place the ants on the lid of the small box in the water basin. The ants will not run around if they are afraid of water.

Use mothballs to draw a circle around the ants. The ants will be afraid of the smell and will not run around.

Observe the ants in a transparent, breathable bottle.

Ant PPT, Part 2: Observing the body of ants

What does the body of an ant look like? Divided into several parts? What does each part look like? Look carefully and draw it as accurately as possible.

Biologists have always used drawings to help them observe animals or plants.

Generally, you first draw the main shape of the animal or plant, then draw the various parts, write down every detail you see, and finally mark it.

Ant body structure

Remember the shape of an ant. The body is divided into head, thorax and abdomen.

A pair of antennae are long on the head, and three pairs of thin legs are on the chest.

Ant PPT, part three: further observation of ants

Ant family

We are soldier ants, with large heads and well-developed mandibles, responsible for defense and defense of our home.

We are worker ants, the smallest and most numerous, responsible for building and expanding nests and gathering food. Raising young ants and queen ants.

We are male ants, responsible for mating with the queen.

I am the queen ant, the largest, responsible for laying eggs and reproducing offspring.

As ants travel, they secrete a pheromone that guides the ants behind them to follow the same route. If we draw our hands across the ants' marching team and interfere with the ants' pheromones, the ants will lose their sense of direction and crawl around. Therefore, we should not interfere with them casually.
