ECOLOGY: LESSON 2

• Biologie
• Middelbare school
• havo, vwo
• Leerjaar 1

MEETING SPRINT 1:

• Is sprint 1 organised?
• Does everyone have acces to all folders?
• Does everyone know what they need to do?
• Is everyone on track?
• Have you organised the scrumboard for sprint 1?
• WILL SPRNT 1 BE FINISHED FOR THE NEXT LESSON?

SPRINT 1 LESSON 2

TODAY:

• biotic and abiotic factors
• adaptations
• review what we have covered

GET TO WORK:

• read pages 283-284
• make a short summary of these two pages
• discuss what you have written down

Biotic factors

Abiotic factors

community

ADAPTATIONS:

• Structural 
• Behavioural
• Physiological

GET TO WORK:

• read pages 290-293
• make a short summary of these 4 pages
• discuss what you have written down

STRUCTURAL:

• A change in the physical build and appearance 
• For example: shape of the body, size of body parts and organs, type of teeth 

Otters have webbed feet to help them swim better. 

Eagles have massive claws to help them grab their prey as they attack from the air.

Sharks (like many fish) have gills which help them breathe under water. 

BEHAVIOURAL:

• A change in the animals behaviour
• For example: change in diet, migration, hibernation, hunting behaviour

Temple monkeys in Bali no longer hunt and gather food because they know they will get fed by the humans visiting the temples.

This is a ground squirrel that is hibernating to survive winter.

Killer whales don't only live in groups called pods, they also hunt in groups.

PHYSIOLOGICAL:

• A body process that helps the organism survive 
• For example: lower heart rate under water, venom from snakes, low water usage 

Penguins lower their heart rate when they dive under water to save oxygen

Seaturtles can hold their breath for hours on end to dive under water. 

Crocodiles that live in salt water have salt glands on their tongue to get rid of the salt that gets in when they grab their prey

PROJECT:

• 7 START-UP QUESTIONS
• Show in pictures and explain at least 4 adaptations your apex predator has made to be able to survive at least:

    --> 1 structural, 1 behavioural & 1 physiological

• extra: vwo must choose one minimum

Star 1

create a biomes diagram of your apex predator. It must have the exact same layout as the one you learned. 

Each box must contain a minimum of 50 words and one picture.

TIP: use canva or prezi

Star 2

Name 5 biotic and 5 abiotic factors that influence your apex predator's existance. Have a minimum of 50 words and a picture for each factor named.

TIP: use canva, docs, slides

Star 3

Create a 5- 10 minute video of the 7 startup questions you answered about your apex predator. You may use existing pictures and video footage of the animal, but you must do the voice over at minimum. 

What now?

• work on sprint 1
• work on your project
• work on your logbook
• work on your mindmap
