Animals Camel
Fennec Fox
Scimitar horned Oryx
Sand Snake
Two toes to help balance on shifting sand
To keep cool
To store fuel during days without food or water
To keep sand out of eyes and mouth
Light coat to reflect heat
To protect joints
Fennec Fox Long ears to get rid of
excess heat
Eyes that can see
clearly in darkness so it can catch
prey
Comes out at night to avoid heat of the day
Hides under tail to protect self from
sun
VegetationBarrel Cactus
Joshua Tree
Prickly Pear Cactus
Thorns to deter predators
Long roots to store water
Flowers can grow even in times of severe lack of water
Xerophytes
A wide-spreading network of shallow roots harvests the desert rains;
a mature plant may soak up as much as 200 gallons of water during a storm.
Waxy skin to reflect heat
Stores water in times of moisture and plumps up
Becomes ridged and thin during very dry periods
Saguaro Cactus
Humans in the desert
Headscarf to protect from heat and sand storms
Loose fitting clothes to disperse heat around
White- to reflect the heat
Open shoes to allow feet to breathe
Sandals to protect heat from hot sand
Clothing
Footwear How does it walk on sand?
How does it get water
Where does it store water?
relationships
How does it stop sand getting in its eyes?
Desert Vegetation
Use the sheets and video notes to
• Design a poster showing how humans, plants and animals have adapted to life in the desert
• Cut the pictures out and stick them on to your poster then add labels to show how they have adapted
Today's task
• Produce an A3 poster • showing how • Animals and• Plants• Have adapted to life in the harsh, hot, dry
climate of the desert• You must include annotated (labeled) pictures• And explain how each have adapted in terms of A) Coping with extreme heatB) Coping with lack of waterC) Escaping predators
You have this lesson ONLY to complete this task
