"Make an Ecological Bottle" Biology and Environment PPT Download

Part One: Pond Ecosystem

Take a look at the pond below. What aquatic creatures are there in the pond? What other non-living things can we find in ponds?

What conditions do aquatic plants need to survive?

Air, soil, water, sunlight...

How do the plants in the pond help the animals?

oxygen, food

What contributions do animals make to plant growth?

Provide nutrients and prevent excessive plant growth...

What effect do the non-living things in the pond have on the living things?

Provide necessary environmental conditions for organisms

Like these living things and non-living things in the pond, they interact and depend on each other to form an inseparable whole. We can think of them as an ecosystem.

A forest, a meadow, a lake, an ocean, etc. can all be regarded as an ecosystem.

Make an ecological bottle PPT, part 2: Design an ecological bottle

We can simulate the pond ecosystem in the classroom or at home and build an ecological bottle for observation and research.

What creatures are you going to let live in the ecological bottle?

What kind of creatures can live in this limited space?

If there are animals, what is their food source?

In addition to adding creatures, do you need something else?

Does the order in which creatures are put in need to be considered?

In order to make these organisms live better in ecological bottles, what else should we consider?

Make an ecological bottle PPT, the third part: making an ecological bottle

According to the design plan, let's make an ecological bottle. Be careful to put fewer critters in the bottle.

Find a large transparent plastic bottle, clean it and cut off the top part.

Put a layer of washed sand at the bottom of the bucket, and then fill most of the bucket with water from natural waters.

Why should Sha Tao be washed clean?

The sand in the eco-bottle represents land, providing a hiding place for microorganisms and a place for bacteria to grow, allowing them to act as decomposers to decompose waste in the ecosystem. Silt can easily make the entire ecological bottle very messy, making it impossible for many aquatic animals and plants to survive, so the sand must be washed away first.
