HELLO MY NAME IS BRANDON SANTIAGO from class 5-888 here are some facts about the desert:

1. The Sahara desert is the largest desert in the desert biome it covers over 300 million square miles.

2.The driest desert on earth receives on average 1 centimeter of rain falls every 5 to 20 years.

3.The deserts are so hot when it rains the water evaporates in the air before ever hiting the ground.

4.but the deserts don't get much rain so they have very little water.

5.The desert biome can be found on every continent except europe.

DO NOT DO THAT


Hello my name is Fidel Ramirez from class 5-777 here are some facts about Desert Ecosystem


1. Well this desert is an ecosystem its made up of living and non living thihgs that interact with each oth

2. And by the amount of rain fall and sunlight they get and the condition of the soil.

3. But plants and animals that live in the desert have to be in the deserts. They can get very cold at night Scorpions ring tailed cat antelope skunks.

4. There are coyotes foxes peccaries tarantulas

  • There are a number of different definitions to describe a desert but they are typically areas that receive extremely low amounts of rain.
  • Deserts generally receive less than 40cm (16in) of rain a year.
  • Around one third of the Earth's surface is covered in deserts.
  • The original meaning of the word desert is 'an abandoned place'.
  • Many of the ice free regions of the Arctic and Antarctic are known as polar deserts.
  • Only around 20% of the deserts on Earth are covered in sand.

Hello my name is Timothy Casiano from class 5-999 i will write some facts about the Desert Ecosystem.

Deserts generally receive less than 40cm cl 16in of rain a year. around one third of the Earth surface is covered in desert. There are hot deserts and sort of in between deserts, too! deserts are also known as arid regions,and they are the driest temperatures in hot desert can reach over 55 degrees celcius.

here are some pictures from my ecosystem:

Desert Facts By: Nicole, Vanessa, and Nathalie


Deserts are primarily defined by lack of rain. Deserts usually get 10 inches or less of rain each year. They have dry soil, little to no surface water, and high evaporation.The rain sometimes evaporates even before hittiime comes. Some deserts are the some of the world's last places of total wilderness. Deserts cover more than one fifth of the earth's land and are found in each continent. Another word for Desert is " Drylands ''. Deserts can lose more moister through evaporation than what they get when it rains. The largest Desert in the world is north Africa's Sahara Desert, it reaches temperatures up to 122 degrees Fahrenhiet (50 degrees Celsius) during the day.

How to create a Desert Terrarium, BY:Nicole, Vanessa, and Nathalie


Make a Desert Terrarium

A Desert themed terrarium is a fun project to make and it is something that is relatively easy to care for. You are using a variety of cactii and succulents which don't require a lot of water and are very tolerant of sunlight. You also do this kind of terrarium in an open dish which is easier to make than in a closed container.
This tutorial take you through all the steps on how to make one of these terrariums.
I also have a video of this project here And Amazon.com has lots of nice Terra Cotta Planters and pots

A Note about changes to this project: I have recieved some helpful advice from an expert desert terrarium maker and he advises me that there really is no need for the Spaghnum moss or the pebbles in this kind of a terrarium. The Spaghnum moss will hold and release moisture which works counter to the concept of a desert terrarium and the pebbles are unnecessary. All you really need is a hole in the bottom of the container and a small piece of screen to keep the soil from falling out. He has tested various configurations and this is the best way to do it. So, no need to use the Spaghnum Moss or the pebbles which saves you time and money! My thanks to R. for this expert advice!!

Here is a list of materials you should have for this project: (Recommended but not all are necessary)
  • A Container (terra cotta or arizona themed is perfect)
  • Several plants, cactii or succulents (generally an odd number is best 3,5 or 7)
  • 1 bag of sand, do not use sand you get at the beach - there are lots of contaminants
  • Potting Soil, can be specifically for cactus or can be general potting soil
  • A dozen stones in a variety of shapes and colors, go find them!
  • Pebbles, Pearlstone or small rocks as drainage in bottom of container (1 or 2 cups is enough)
  • Spanish Moss or Sphagnum Moss (Acts as a barrier so soil doesn't work its way down into the bottom of the dish or pot
  • Arizona or desert themed ornaments


The Basic Layout
The illustration here on the left shows the basic layout for your desert terrarium. It is very similar to a regular terrarium but here are some things to note.
If you are using some [[@http://onlinedealgrab.com/?se=inline.local&q=large stones|large stones]] you should embed them rather deep into the soil. I put a couple of inches of soil in the dish, placed the stones then placed more soil.
The sand is also something not seen in a regular terrarium. I have put a thin layer of sand on the top of the soil. This was before placing the plants. Then after the plants were placed I touched it up with more sand.

Here is the basic Procedure:
  1. If there is a hole in your dish place a small piece of screen over it to protect from soil and stones falling out
  2. Place about an inch of pebbles or pearl stone in the dish
  3. Place a half inch to inch layer of [[@http://onlinedealgrab.com/?se=inline.local&q=activated charcoal|activated charcoal]] (this purifies the water and soil and is totally optional in an open dish like this
  4. Place an inch thick layer of sphagnum or spanish moss (this prevents soil from seeping down into the bottom of the dish)
  5. Fill about half the intended final volume with soil
  6. Place your larger stones and arrange them in a pleasing manner
  7. Place the remainder of the soil
  8. Put your plants in an attractive arrangement and one nice way to do it is to try to get a plant or two between the stones and try to get one or two of them on a higher level. The whole arrangement is shaped like a volcano with the center of the dish being where the highest point is.
  9. Place some smaller colored stones in the dish
  10. Touch up the sand by adding more sand
  11. Add any ornaments or artistic touches (I have added a lizard)

Care of your terrarium
The plants have been shocked by being transplanted so for the first week you need to watch them carefully. Keep any tags or guidelines that came with the plants. These are valuable instructions that will help you in watering and sunlight needs.

Further Notes
I bought several different kinds of succulents and cactii from a [[@http://onlinedealgrab.com/?se=inline.local&q=local home improvement|local home improvement]] store. This kind of plant often has a plastic container that is full with a number of plants. i gently separated them and used them both as individuals and as small clusters. I also cut away a lot of the excess roots before I planted them in my terrarium.

Introduction
Hi my name is Nathalie Alvarez and the ecosystem i chose to study and experiment on is the Desert Ecosystem. I am 10 years old and I am in 5-1 Ms.Occhipinti's class. My partners are Nicole, and Vanessa, the reason why I chose the Desert Ecosystem is because i was fascinated by how the plants and animals survive in such a hot and dry place with very low rain. Also, for our project we are making a Desert Terrarium. Another incomplete project, is that we bought a desert animal which is a Guinea Pig, guinea pigs are related to most of the animals that are living in the desert, since i take care of them i observed that when [[@http://onlinedealgrab.com/?se=inline.local&q=i clean|i clean]] their cages and i try to carry the mother guinea pig she goes to a corner and she kicks bedding to my hands and makes a angry noise; she is protection her babies from being hurt since she is pregnant. In conclusion, according to my studies some of the desert animals like guiena pigs protect their babies by kicking bedding,sand,etc. to that animal/person, also if i continue my studies I know almost everything on how desert animals and plants survive in such a hot place where there is barely any rain or water.

Summary: The Desert Ecosystem


We have been able to research about the Desert Ecosystem far enough to understand it, in order to keep track of the animals and plants living there and what they do to survive in such a dry and hot environment.
Deserts are found across our planet along two fringes parallel to the equator at 25–35° latitude in both the northern and southern hemispheres. Deserts are arid or dry regions and receive less than 10 inches of rain per year. Biologically, they contain plants and animals adapted for survival in arid environments. Physically they are large areas with a lot of bare soil and low vegetation cover. The world’s deserts occupy almost one-quarter of the earth’s land surface, which is approximately 20.9 million square miles. Many other ways to know what is going on in this dry and hot environment is to go on websites to research about them such as this website:
http://www.defenders.org. However, the survival life in the desert is not very easy because there are threats to this ecosystem. The military activities and off-road vehicles do cause extensive, lasting damage to the fragile desert cover. Although, mining activities affect small areas directly, they have significant impacts on surrounding areas. The Mojave Desert is so diverse that it is subdivided into five regions which are Northern, south-western, central, south central, and eastern. The elevations range from below sea level at Death Valley, National park to 2.26 miles on MT.

Hello my name is Jocelyn Ramales and my partner name Evelyn Flores
We all know deserts are dry,but did you know that Mojave has an average rainfall of only five inches.For comparison, the average rainfall in Mobile, AL sixty-seven inches.
There are even part of the Atacama Desert in Chile where no rainfall has ever been recorded.The Mojave Desert is home to Death Vally, which gets its name from being the
lowest, driest,and hottest place in North Ameria.
