Welcome to Haywood Academy Science department! WEEK 3

PART 1 - CLASSIFYING ANIMALS

Task 1 - Putting Animals into groups! Decide if the following statements are true or false… 1) There are estimated to be 8. 7 million species (different types of living things) on Earth. 2) Scientists have only actually discovered around about 1. 3 million species so far (so most species have never actually been seen before!) 3) Some living things have been found living in water that is over 1220 C 4) There is a type microscopic living thing called a Tardigrade (water bear) that can survive being boiled in water, starved for years, frozen to -250 o. C or even in space. 5) Currently over 1 million different species are at risk of extinction (completely dying out) LOOK AT THE NEXT SLIDE FOR THE ANSWERS!

Task 1 - Putting Animals into groups! THEYANSWER ARE ALL TRUE! LOOK AT THE FINAL SLIDE FOR THE ANSWERS!

Look at these pictures for one minute (don’t write anything down! Then look away from the screen and try to write them down from memory only.

If you correctly remembered: 8 – You have a good memory 10 – You have a very good memory 12 – You have an excellent memory. 15 – You have an amazing memory! NOW TRY THE NEXT CHALLENGE!

What if there were 100 animals on the page to remember? What if they were animals that you had never seen before? How would this affect your score?

What if there were 100 animals on the page to remember? Its really hard to remember that many animals! What if they were animals that you had never seen before? If you have never seen the animal how can you name it!

There at least 8. 7 million different types of living things so we can’t remember all of them! We need another way… CLASSIFICATION. We put animals into groups based on their features. These are normally the features we can see.

What features do these two animals have in common? Stripes Four legs Both have a back bone Two ears etc

What features are different? Tiger has sharp teeth Tiger has eyes on the front of its head

What features are different? Tiger has sharp teeth Tiger has eyes on the front of its head

A B C We can use a classification key to identify animals based on their features… Can you follow the key? D E

Tree snake Garter Snake Answers King Cobra We can use a classification key to identify animals based on their features… Can you follow the key? Crocodile Alligator

Draw your own classification key (like the example) to help people identify the different animals above!

ANSWER – REMEMBER THAT YOUR KEY DOES NOT HAVE TO LOOK EXACTLY LIKE THIS!

PART 2 - STAYING HEALTHY

YOU ARE A DOCTOR AND THIS IS YOUR FIRST PATIENT… - WHAT ADVICE WOULD YOU GIVE HIM TO IMPROVE HIS HEALTH? WHY?

POSITIVE LIFE STYLE CHOICES NEGATIVE LIFE STYLE CHOICES How many positive (good) and negative (bad) life style choices can you thin of?

POSITIVE LIFE STYLE CHOICES Lots of exercise NEGATIVE LIFE STYLE CHOICES Smoking Eating fruit and OF vegetables Taking drugs EXAMPLES POSITIVE AND NEGATIVE LIFE STYLE Getting enough sleep(YOU MIGHT Spending hours per day on CHOICES HAVE 5 OTHERS!) games console Balanced diet Drinking water Eating lots of processed food e. g. fast food Eating snacks between meals Drinking lots of alcohol

Heart attack Stroke (bleed in the brain)

‘Operation Ouch’ the heart

From the head and body Right Atrium To the lungs To head and body

From the head and body Right Atrium Right ventricle To the lungs ANSWERS! From the lungs Left Atrium Left Ventricle To head and body

Maths challenge! Imagine that your heart beats 60 times in on minute: 1) How many times will it beat in an hour? (60 seconds in an hour) 2) How many times will it beat in day? (24 hours in a day) 3) How many times in a year? (365 days in a year)

Maths challenge! Imagine that your heart beats 60 times in on minute: 1) How many times will it beat in an hour? (60 seconds in an hour) 60 x 60 = 3600 times 2) How many times will it beat in day? (24 hours in a day) 3600 x 24 = 86, 400 times 3) How many times in a year? (365 days in a year) 31, 536, 000 times

The life expectancy for a woman in uk is 83 years old. This means that if the heart beats for 60 beats per minute for this persons whole life it will beat a total of: 2, 617, 488000 times That’s over 2. 6 billion times without stopping!

So why does the heart need to beat anyway? To send the blood to the heart through blood vessels… Look at the diagrams, what is the difference between an artery and vein?

What exactly is the blood made of? Carry oxygen to your cells Carry sugars to your cells Fight infection

Quick Quiz… What am I? 1) I am the name of the blood vessel that carries blood back to the heart 2) I am the name of the blood vessel that carries blood away from the heart 3) I am carried by red blood cells 4) I am carried in the blood plasma 5) I am a type of cell that fights infection 6) I am the name of the heart chamber that sends blood to the lungs 7) I am the name of the heart chamber that sends blood to the left ventricle 8) I am the name of the blood vessel with thick elastic and muscular walls
