The soil provides plants with the support and nutrients they need to grow. • Observation of the soil in an ecosystem • You want to determine the best soil for growing plants in a garden. • Collect a sample of your garden soil, construction soil and sand. Label the pots. • Observe the three samples and compare the physical differences. Feel each sample with your hands. • Get three flasks with water and put the soils into them. Allow the samples to settle for 15 min. • Complete the chart. • By your observation, infer which soil contains more water and air. • Which soil do you recommend to use in a garden?
Conclusions • The most convenient soil to grow plants is the garden soil with compost
The airprovidesthe gases tocarryoutthelifeprocesses of allthe living things. The Atmosphere It is a layer of gases which surrounds the earth. Air is a mixture of several different gases. • Atmosphere • What is the percentage of oxygen, nitrogen, carbon dioxide and argon in the atmosphere? • Which gas is found in larger amounts in the atmosphere? • Why are carbon dioxide and oxygen so important? • How can we identify these gases? • What are the uses of the gases in the atmosphere?

Climate change • The climate is undergoing changes . Some scientists believe that these changes such as hail, severe storms, tornados, hurricanes, floods and droughts are a consequence of the accumulation of carbon dioxide and other green gases in the atmosphere. Green gases trap the heat of the sun so the temperature of the atmosphere is rising. This causes a hotter atmosphere in all the planet. This is called global warming.
