"Make an Ecological Bottle" Biology and Environment PPT

Part One: Understanding Ecology

1. What living and non-living things are there in the pond?

2. What is the relationship between living things and non-living things?

3. What are the functions of living and non-living things?

Organisms: algae, aquatic plants, Spirogyra, fish (small fish, large fish or omnivorous fish, omnivorous and carnivorous fish), shrimps, snails, river mussels, water birds, aquatic insects, frogs, etc.

Non-living things: air, water, soil, rocks, etc.

Relationship: Water provides a place for fish to live. Stones provide hiding places for fish; aquatic plants provide fish with enough oxygen and shelter, and provide food for fish; animal excrement is nutrients for plants, and so on.

Function: In the pond ecosystem, sunlight shines on the lake surface, continuously providing energy for the ecosystem; the water in the pond, the air and nutrients dissolved in the water, as well as the organic matter and inorganic salts deposited on the bottom of the pond, these They are all non-living substances in this ecosystem. Abiotic substances and energy in ecosystems mainly include sunlight, heat, air, moisture and inorganic salts, etc.

Make an ecological bottle PPT, part 2: hands-on practice

Explore and discuss, propose design plans

think:

1. What creatures are you going to let live?

2. What kind of creatures can live in this limited space?

3. If there are animals, what is their food source?

4. In addition to creatures, is there anything else needed? Does the order in which creatures are put in need to be considered?

Experimental method steps:

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

2. Put a layer of washed sand at the bottom of the bottle, and then add half of the bottle with water from natural waters.

3. Plant a few aquatic plants in the bottle and put some duckweed on the water.

4. After the plants survive, add small fish or small animals such as loaches and snails.

5. Put the label with the name of the group member on the outside of the ecological bottle.

Make an ecological bottle PPT, the third part: expansion and extension

The Ecosphere is the world's earliest fully enclosed ecosystem - a complete, independent and self-surviving miniature world enclosed in glass. It uses NASA technology, perfectly combines scientific knowledge and artistic appreciation, and demonstrates the interdependent relationship between animals, plants and water resources on the earth in the simplest and most vivid way. Since its advent in the early 1990s, the Eco Ball has been dubbed a "scientific project", "the world's most worry-free pet" and "enclosed aquarium". It integrates multiple values ​​such as decoration, appreciation and education, and achieves It is the most rare gift to give to relatives and friends.

Make an eco-bottle PPT, part 4: Class summary

Organisms interact and depend on each other in a certain area, forming an ecological community.

In nature, just like ecological bottles, if environmental conditions are damaged, biological survival will be affected.
