  1. Are you environmentally-minded? SCORE Always=4 usually=3 sometimes=2 never=1 X • I turn off the lights when I leave the room. 32 • When I see paper on the floor, I stop to throw it away. • I write on both sides of a piece of paper. • I turn off water when I brush my teeth. • I always check the lost property box. • I reuse plastic bags and newspapers. • I recycle plastic bottles and caps. • I organise and clean my place (desk, hanger,locker).

  2. Now use your answers to make a line graph on this graph.

  6. WHAT IS ENVIRONMENT? • It is what surround us. There are living and non living things such as people, plants, microbes, computers, paper, chairs, air…. WHAT IS AN ECOSYSTEM? • An ecosystem is a community made up of living and non-living things. Different ecosystems have different light, soil, water and temperature conditions. This determine which plants and animals can live there.

  10. ABIOTIC FACTORSFormation of the Earth page 68 • Soil • Air (humidity) • Water • Light (shade) • Temperature

  11. 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?

  12. Conclusions The best soil to grow plants is the loam because it has a lot of air, water and organic matter that the plants need. This is very important to choose loam soil and take care of it to grow crops and produce enough food.

  13. ROCKS • There are threedifferentkinds of rocksonEarth, and theyweremade in verydifferentways. The firstkindisigneous rock, whichmeans "firerocks". Igneousrocksstartedoutfarunderground, whereitisveryhot and theyweremelted. Thentheyshotout of a volcano as lava, and cooled back intorocks as theyfell back downtoearth, oraftertheylanded.Granite, basalt (pomez)and quartz are a commonigneous rock. • The secondkind of rock issedimentary rock, or "sitting rock". Thisis rock thatwasoriginallymud, ortheshells of tiny sea creatures. The little bits of dust, ormud, orshellsfalltotheground, ortothebottom of a pondorocean, and getcovered up by more layers of mudorshells. Eventuallythepressure of allthestuffon top of themmashesthemtogetherinto a hard rock. Limestone, shale and sandstone are commonsedimentaryrocks. Fossilsformed in sedimentaryrocks (page 67) • The thirdkind of rock ismadeout of thefirsttwokinds. Wecallthesemetamorphic, or "changed" rocks. Metamorphicrocks are not as common as thefirsttwo, butsometimesanigneousor a sedimentary rock meets up with a lot of heatorpressure and thismakescrystalsform in therocks, or, ifthe rock already has crystals, it can makebiggercrystals.

  15. Answer these questions in your personal folder • 1-What is soil? • 2-What are the horizons in the soil? • 3-What are the differences among the horizons? • 4-Explain why the soil takes a lot of time to form, include the role of the living organisms in this process.

  16. Do this experiment in the lab 1-Get samples of humus, sand and clay soils in three glasses. 2-Compare the size of their particles. 3-Put each of them into transparent glasses and allow them to settle down for half an hour. 4-Observe where the different particles of each soil set. 5-Filter each soil and answer the questions: -Which soil does not retain water? Why? -Which soil retains water and is sticky? -Does humus retain water?

  17. Learn to study : SOILS • Complete the mind map about soils • Look for information about how the man changes the soil. (include google images) . What are the consequences of changing the soil in our environment? (include google images) . Make a poster in groups using all this material.

  19. 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? Use a table like the following one to answer this question. • Carbondioxide • Oxygen • Nitrogen • Argon • 1.Used to put out fires • 2. • 6. What are the names of the other gases in the air?

  20. Fossils

  21. Water is needed for life processes. Water cycle 1.Why is water so important? 2. What are the three forms we can find water in? 3. What is the freezing point of water? 4.What is the boiling point of water? 5. What is the water cycle? Explain this with a diagram showing the water in its three states.
