STUDYING PLANTS IN NATURE

The best way of learning is practicing and observing it, that is why our students have taken advantage of  our school and have prepared a great project about plants and flowers!


It has been a really wonderful time, keeping in touch with nature!





























FOSSIL PLANTS


When an animal or plant dies, it usually decays quickly. Dead animals are often eaten. Sometimes, though, an animal’s body sinks into thick mud. The mud contains no air so the remains don’t decay. Animals can’t disturb the remains.

Here the remains may rest for thousands or even millions of years. Over time, more mud presses down on the remains. Minerals dissolved in the mud turn the remains to stone. These remains are called fossils and they give scientists clues about what life was like on our planet.

Fun Facts About Fossils 

  • Without fossils, we wouldn’t know about dinosaurs.
  • Some fossils are of footprints.
  • It’s pretty unusual to find a whole fossilized animal. Scientists usually find shells, bones and teeth instead.
  • Scientists have found fossils of feathered dinosaurs.
  • Sometimes animal and plant remains are preserved, but they’re not turned to stone. Insects were stuck in sticky tree resin. The tree resin turned to amber over millions of years, but the insects are completely intact inside.

FLOWERS

 Plants start their lives as tiny seeds. Seeds can be as tiny as a grain of side or bigger than a fingernail. Some are round, while others are flat or tear-shaped. Inside a seed is an embryo, which is a tiny plant. 


Fun Facts about Reproduction of Plants for Kids

  • All seeds need moisture, oxygen and the right temperature to germinate, or grow. 
  • Some seeds need light to germinate. Others need darkness.
  • Some plants, like ferns, don’t produce seeds. They make spores. Look under the leaves and you’ll see rows of tiny round spores. These drop off the plant and eventually make new plants.
  • Some seeds are carried to new places by the wind.
  • Seeds don’t grow well if they land right underneath the parent plant. There’s not enough light, water or nutrients here.

PHOTOSYNTHESIS

Photosynthesis is the process by which plants make their own food.  

To make food plants need:


  • carbon dioxide
  • water
  • sunlight



Why is Photosynthesis Important?

Photosynthesis is important because it provides two main things: 
      • food
      • oxygen

Continents and Pangea



  • The seven continents are the seven main land areas on the Earth. Some are joined to each other, and some are completely surrounded by water. Some continents have a lot of countries, but others have only a few.


  • It is believed that in past ,all continents were joined, this land area was called Pangaea .This area started to break up & got divided into 7 parts ,so today we have 7 continents .These continents are still moving away or moving close to each other. This is called continental drift or plate tectonics theory. For example Europe & North America are said to be moving 7 cm apart every year
