What will you learn today? What is the Jurassic Coast and how did it form? What is the Rock Cycle? How do Fossils form? What can Fossils tell us about the past? Activities and ideas for EYFS, KS1 and KS2

World Heritage Convention 1972 IDENTIFY PROTECT PRESERVE Temple of Abu Simbel moved during flooding of Aswan Dam, Egypt, 1972
4
Stonehenge, UK Pyramids, EgyptGreat Barrier Reef, Australia Great Wall, China
5
World Heritage Sites all have Outstanding Universal Value Something that is so precious that it must be preserved and protected For now and for the Future For all of Humanity
6
What is a World Heritage Site? 1031 natural (197) and cultural (802) sites around the world have been included on the UNESCO* World Heritage List Together they form a common heritage of humankind Their protection is our shared responsibility These are the ideas on which the World Heritage Convention is based. *United Nations Educational Scientific and Cultural Organisation

The Jurassic Coast was given World Heritage Status in 2001 and was England’s first natural World Heritage Site. Offers a unique geological exposure along 95 miles of coast
8
Lets take a quick look at the Jurassic Coast Jurassic Coast Spot the coastal feature…
9
95 miles of World Heritage Site Exmouth to Studland Bay – 155km (95 miles) Gateway towns excluded from WHS boundary 3 geological periods – 185 million years of time
10
A narrow strip of coast between break in slope and mean low water mark Offshore boundary follows Mean Low Water Mark Car Park and developed area excluded from site, WHS boundary follows SSSI Landward boundary follows break of slope at top of cliffs GATEWAY TOWN
11
Lets look deeper…. What’s inside our Earth?
12
Plate Tectonics The plates shift around causing earthquakes, tsunamis and volcanoes
13
The rock cycle http://www.bbc.co.uk/bitesize/ks3/science/images/rock_cycle.gif
14
Sandstone
15
Made up of squished together grains of rock Thin section
16
Full of life Barren, no life
18
Lets make the Jurassic Coast out of Play dough!
19
TURN YOUR 3 PIECES OF PLAYDOUGH INTO 4 (They might not be in these exact colours ) TRIASSIC 250 million years ago JURASSIC 200 million years ago CRETACEOUS 145 million years ago UPPER CRETACEOUS 100 million years ago
20
Break up your TRIASSIC ROCK into pieces. This is EROSION!
21
Now squish your bits of rock together, this is DEPOSITION

23
Now, break up your JURASSIC ROCK into pieces.
24
Now squish your bits of JURASSIC rocks on top of your TRIASSIC rocks. This is DEPOSITION! See your ROCK LAYERS form!
25

26
Do the same with your CRETACEOUS rocks
27
Cretaceous shallow seas © Dorset County Council
28
You now have the 3 rock layers of the Jurassic Coast! CRETACEOUS JURASSIC TRIASSIC
29
The rocks were laid down in a gently subsiding basin Lower Cretaceous – 100 to 144my Jurassic – 144 to 200my Triassic – 200 to 250my WestEast
30
The rocks were then tilted to the east and faulted (not shown) WestEast TILT YOUR ROCK LAYERS!
31
The rocks were then tilted to the east and faulted (not shown) WestEast
32
The rocks were then tilted to the east and faulted (not shown) WestEast
33
Push your rock layers over so they tilt to one side
34
They then became exposed to erosion which was greatest in the west WestEast CUT THEM LEVEL (EROSION)
35
Erode your layers by slicing them with the stick
36
The remaining Cretaceous rocks were then deposited on the eroded surface WestEast NOW PUT ON YOUR FINAL LAYER (Upper Cretaceous) DEPOSITION
37
Break up your UPPER CRETACEOUS rock and squish them gently on top of your rock layers
38
Here is a model of your Jurassic Coast. 185 million years of Earth’s History from one end to the other! OLDEST (250 MILLION YRS OLD) YOUNGEST (65 MILLION YEARS OLD) TRIASSIC JURASSIC CRETACEOUS UPPER CRETACEOUS Unconformity

EYFS/KS1 Resources 10 Free activities adapted for EYFS/KS1 from our KS2 resources Fossil Hunter Lottie Doll: Perfect for storytelling, role play, boys and girls Download files from Lottie.com and soon on jurassiccoast.orgLottie.comjurassiccoast.org In partnership with
43
Fantastic Fossils Fossils are the remains of once living animals or plants. People have been finding fossils in rocks for thousands of years, but until quite recently they didn't understand what they were. Today we recognise that the fossils we find in rocks represent the ancestors of the animals and plants that are alive today.
44
How do Fossils form? Can you put the story about my life in the right order? KS2 Science, Geography, English EYFS/KS1 adapted activity herehere
45
Insects Fossil wood The fossils record virtually a third of the record of life Marine reptiles Fish Turtles & crocodiles Trace fossils Fossil Forest Dinosaurs (footprints)
46
Stories in Stone Part of a trackway recording Iguanodon and Megalosaur footprints The dinosaur making the track initially turned to the left before hesitating, and then after adjusting the position of its feet, resumed the original direction. A unique moment of indecision recorded from 140 million years ago!
