1S1 Science RocksNEW LEARNINGThrough evaluation of a range of data, I can describe the formation, characteristics and uses of soils, minerals and basic types of rocks.SCN 3-17aREVISIONHaving explored the substances that make up Earth's surface, I can compare some of their characteristics and uses.SCN 2-17a
2Starter Questions What do you think the Earth is made of? Are rocks: Alive, Dead or Never Alive?Write down 3 words to describe rocks.
3Structure of the Earth Today we will learn to Describe the layers which make up planet EarthWe will do this byListening to a description, drawing a diagram and answering questions.We will have succeeded ifWe can describe the Earth to an alien (or our parents!).
6Inside the EarthInner Core: Mostly iron, dense ________, temperature about ________!Outer Core: Mostly iron, dense ________, temperature about__________.Mantle: Less dense than _________, temperature about ________.Crust: Between __ and 90km thick. Least dense rock, __________ part.
8Today we’ll be…..Learning how different types of rock form.By the end of the next couple of lessons...You will be able to explain how crystals form inside rocksWe’ll do this by….Examining different rock types, watching a film about how they form, and answering some questions.
16Today we’ll be…..Learning how crystals form in igneous rock.By the end of the lesson...You will be able to explain why crystals in rock are different sizes.We’ll do this by….Doing an experiment to cool hot liquid and examining what it looks like afterwards.
19Crystals in Igneous Rock The crystals in _______ rock form as the hot m_______ (lava) cools down.Different sized crystals form because the magma _______ at different rates in different places, dependent on the t__________.
20Crystals in Igneous Rock The crystals in igneous rock form as the hot magma (lava) cools down.Different sized crystals form because the magma cools at different rates in different places, dependent on thetemperature.
21Sedimentary Rocks How They are Made Wind and water break down existing rocksBits of existing rock settle in lakes and riversLayers are formed and build up as the existing rocks stick togetherPressure and time turn the layers to sedimentary rock
22Types of Sedimentary Rocks MudstoneSandstoneLimestoneGypsumCoalRock Salt
23Metamorphic Rocks What are They? Rocks that have changedThey were once igneous or sedimentaryPressure and heat changed the rocksThe newly formed metamorphic rock can have different properties to the rock it was formed from
24Types of Metamorphic Rocks GneissmarbleSlateMica schist
25Rocks Have Been Used For Many Years and For Many Things
26What type of Rock are the following made from ? The White HouseTaj MahalMade from sandstonethen painted whiteMade from Indian marble
33Today we’ll be…..Learning how fossils form in sedimentary rock.By the end of the lesson...You will be able to explain how fossils were preserved on the sea bed.We’ll do this by….Doing an experiment to look at how fossils were preserved and discussing fossils
34Has our country always been here? Most of our country is made from sedimentary rock – what does this tell you?Our land was once underwater!
35Fossils Fossils are traces of prehistoric life They are plants or animals that were buried in sediment and preservedUsually it was the print that was left – the rock in the shape of the animal or plantThe types of fossils in an area give clues to the area’s history
36Making fossils – 1 between 2 Put your initials on the cardboard and tape your cardboard in a circlePut plasticine in the bottom of the cardboard and make an impression of your shell in this – this is your mouldAdd 40ml of water to the plaster of paris – gently squeeze the bag until all of the water is gonePour the plaster into your mould and leave it on the window ledge to set
37Today we’ll be…..Learning what soil is made of.By the end of the lesson...You will be able to explain what the three main components of soil are.We’ll do this by….Doing an experiment to heat soil and weighing it before and after.
38Soil What do you think of soil? It doesn’t look like much, but it is full of life
