NextBack Slide 5 Click on the picture to go to the lesson (a short quiz will follow each lesson) 1:What are insects? 2: Parts of insects 3: Types on insects 4: Importance of insects Vocab Slide 6 Basic Insect Vocabulary Nectar- a sweet fluid given off by plants that bees use to make honey. Pollen- tiny particles in flowers that fertilize seeds. Antenna- a pair of skinny, movable organs on an insects head that can feel, taste, and smell. Exoskeleton- a protective and supportive covering of the body. Thorax- the middle of the three main divisions of an insects body. Abdomen- the bottom part of an insects body, behind the thorax. Molting- to shed the outer skin and replace it with new skin. Arachnid- part of the arthropod class and includes a body divided into two regions with four pairs of legs but no antennae. Pest- a plant or animal harmful to human beings or their needs. Dung- solid waste of an animal. Maggots- soft-bodied legless larva of a fly. NextBack Main Menu Slide 7 Insects are invertebrates! Invertebrates means they do not have backbones! All insects come from eggs! Most insects can fly, but some walk or jump! What are insects? NextBack Slide 8 Where Do Insects Live? Insects live outside! Different insects have different places they call home! Many insects live in grassy areas or places with a lot of mud or dirt Under rocks are also a common place to find insects Many insects also leave in trees, lakes and streams! NextBack Slide 9 Much like with where they live, what insects eat differ among different kinds of insects Most insects eat plants but some eat other insects! Nectar (found in plants) is also a common food choice for insects Almost all insects will eat anything they can find including those cookie crumbs you dropped on the floor! Some (like mosquitoes) even eat blood! What Do Insects Eat? NextBack Slide 10 Insects are invertebrates. All insects come from eggs. Most insects can fly, but some walk or jump. Different insects call different places home. Insects can live in grassy or muddy areas, under rocks, in trees, streams and lakes. Different insects eat different things. Insects eat nectar, plants, other insects, and trash. What Are Insects Summary NextBack Slide 11 1.) In the sky! 1.) In the sky! 2.) On the land! 2.) On the land! 3.) It depends on the insect! 3.) It depends on the insect! Where Do All Insects Live? Back Slide 12 While most insects live on the land, and many fly in the sky different insects have different places that they like to call home! You have now finished lesson 1! Click the main menu button to go back to the main page and begin your next lesson! Great Job! Main Menu Slide 13 While many insects FLY in the sky, not all insects LIVE in the sky. Return to the quiz page and try again! Nice Try! Back Slide 14 While many insects live on land, there may be a better option that answers the question where do ALL insects live! Return to the quiz screen and see if there is an answer that fits better! Lets Try Again! Back Slide 15 All insects have: 6 Legs One Antennae Three Body Sections An Exoskeleton Parts Of An Insect NextBack Slide 16 ALL insects have 6 legs, one pair on each of the three parts of the body! Insects antennae are located on their heads Insects use antennae to hear, smell and feel! 6 Legs, One Antennae NextBack Slide 17 Head (Top) The head includes eyes, antennae and a mouth! Insects eyes have THOUSANDS of lenses! This lets them have a wide field of vision which helps protect them from predators! Not all insects have the same mouth! Some insects use their mouth to drink their food while others use it to chew and swallow food! Thorax (Middle) The thorax is three parts. Each part contains a pair of legs Some insects Thorax are covered by wings, so even though you dont see them, theyre still there! Abdomen (Bottom) Wings are also located on the abdomen The abdomen contains an insects respiration, digestion and reproductive organs. Insects breathe through openings on their abdomens since they dont have noses! Three Body Sections NextBack Slide 18 Insects do NOT have bones or a skeleton, they have an Exoskeleton!!!! When insects are ready to grow, they have to break through their exoskeleton and swell up to their new size before their new skin grows! This is called molting Exoskeleton NextBack Slide 19 All insects have 6 legs Insects use their Antennae to hear, feel and smell All insects have 3 body parts: a head, a thorax and an abdomen Insects breathe out of their abdomen since they dont have noses! The abdomen contains the insects respiration, digestion and reproductive systems! Parts Of An Insect Summary NextBack Slide 20 A.) The head, the thorax and the abdomen A.) The head, the thorax and the abdomen B.) The head, the antennae and the bottom B.) The head, the antennae and the bottom C.) The head, the antennae and the eyes C.) The head, the antennae and the eyes What are the three parts of an insects body called? Back Slide 21 Youre correct! The three parts of an insect are the head, the thorax and the abdomen. Good job! Great Job! Main Menu Slide 22 While all insects do have a head and antennae, the antennae is not considered one of the three major body parts of an insect. Also the bottom of an insect is really called the abdomen. Return to the quiz slide and see if you can decide the correct answer. Good luck! Nice Try! Back Slide 23 While all insects do have a head, antennae and eyes, those are not considered the three major body sections of an insect. Return to the quiz page and guess again! Lets Try Again! Back Slide 24 Types Of Insects There are over a million different kinds of insects! In fact, insects make up half of all the living things in the world! WOW! Some of the most common kinds of insects include Beetles and Lady Bugs Bees, Wasps & Ants Flies Butterflies, Moths & Worms Did you know that spiders are NOT actually insects? While many refer to them as insects or bugs they are actually arachnids! Next Back Slide 25 Beetles & Lady Bugs Beetles: There are over 300,000 species of Beetles! Beetles live on land and in freshwater! Beetles are usually brown or black but can come in every color under the sun Most Beetles eat plants, fruit and wood Lady Bugs: There are 5,000 species of Lady Bugs! Lady Bugs colorful skin warns predators that they dont taste good! Female Lady Bugs are bigger than men! Lady bugs are found all over the world! NextBack Slide 26 Bees, Wasps & Ants Bees: Bees favorite foods are nectar and pollen! Bees make honey Bees such as honeybees and bumblebees live in colonies or hives and work together for the good of their hive. Like humans, each bee has its own job to do. Wasps: There are 30,00 species of wasps---- and most do NOT sting humans! Wasps have a more narrow waist- or middle section- than bees do. Wasps are important to control pest populations NextBack Slide 27 Flies There are over 100,000 species of flies Flies have only two wings which help them get around they can fly up, down, side to side and even backwards! Flies use their hairy, sticky feet to stick to almost any surface even the ceiling! Flies dont have teeth; they use their tongue to suck up food like a straw Flies like to eat manure or garbage for food. Thats why if you dont clean up, a LOT of flies will appear! Flies can carry diseases! NextBack Slide 28 Butterflies, Moths & Worms Butterflies Before butterflies become the pretty creatures we know them as, they go through a life cycle which includes the egg stage, the caterpillar stage, the pupa stage and finally the butterfly stage. Most butterflies eat nectar or plants Butterflies taste with their feet! There are 20,000 different species of butterflies Moths Moths are very alike butterflies, but they have some distinct differences! Moths fly at night Moths are very hairy!!! NextBack Slide 29 There are over a million different kinds of insects! Common insects include beetles, lady bugs, bees, wasps, ants, flies, butterflies, moths and worms. Spiders are NOT insects! Spiders are arachnids. Types Of Insects Summary NextBack Slide 30 1.) About 100 1.) About 100 2.) 5 2.) 5 3.) Over a million 3.) Over a million How many different kinds of insects exist? Back Slide 31 100 was a good guess, but lets go back and see if you can find an answer that fits better. Revisit the introduction slide if you need a refresher! Nice Try! Back Slide 32 That was a good guess, but its not exactly right! While there are 5 slides about different kinds of insect on this PowerPoint, there are a lot more than just 5 kinds of insects in the world! Try again! Lets Try Again! Back Slide 33 There are over a MILLION different types of known insects living on this planet! There are even more that havent be discovered or classified yet! Click the main menu button to go back to the main page and begin the next lesson! Great Job! Main Menu Slide 34 Many people think insects are gross or, even worse, are afraid of them! But the truth is, many of the same insects that people are afraid of help us out a lot in everyday life! Why Are Insects Important? NextBack Slide 35 Some insects at plants and crops which are important to farmers! Other insects eat those insects before they have the chance to ruin the farmers plants! Ladybugs are one of the good guy bugs! Lady bugs eat aphids which like to munch on farmers crops- which turns into your food! When these insects fight off the dangerous insects, farmers dont need to use poisons on their crops which means healthier food for everyone!!!!! They Fight The Bad Guys! NextBack Slide 36 Everyday around the world, millions of bugs produce dung which they drop onto the ground! If there werent dung beetles around to get rid of all the waste, could you imagine how stinky and dirty our Earth would get? Dung beetles roll the pieces of dung up into balls and burry, eat, or lay their eggs inside of them! They find a way to eliminate or make use of the waste! Many bugs such as crickets, roaches and beetles also eat the dead plants, leaves, branches and trees that fall on the ground each day. Bugs Recycle Waste! NextBack Slide 37 Some insects, called pollinators, carry pollen from one flower to another to be fertilized which lets them make yummy seeds and fruit like peaches, watermelons and apples! These insects include beetles, wasps, bumblebees and flies. Bugs Spread Pollen NextBack Slide 38 Without bugs, it wouldnt be possible for us to have a lot of different foods and materials! Honeybees, for example, make honey! Some caterpillars called silkworms make silk! Silk can be used to make clothes, bedding and many other kinds of cloth. Cochineals produce red dye used to make clothes, lipstick, paint, pills, candy and juices! Bugs Make Things NextBack Slide 39 Studying how insects use their six legs to move around has helped man scientists learn how to build better robots to use for exploring other planets! Blowflies produce tiny maggots which doctors can place on slow healing wounds (cuts) and the maggots give off juices that digest dead or infected tissue and bacteria which lets the wounds heal! Bugs Help Doctors and Scientists NextBack Slide 40 Insects are food to countless creatures Snakes, birds, fish and lizards eat insects! In places such as Asia, Africa and South America, many people eat bugs which are very high in protein and good for you as long as you pick the right bug! Bugs Feed Animals And Humans Too! NextBack Slide 41 Bugs fight bad guys who want to kill our food before its fully grown. Bugs get rid of waste such as dung, dead plants and leaves and fallen trees so they dont pollute our Earth. Bugs spread pollen from flower-to-flower which lets us get delicious fruits like apples and watermelon. Bugs help doctors and scientists by eating bacteria and dead tissues which allow sick or hurt people to heal. Bugs, which are a great source of protein- feed many animals and even humans around the world. Why Bugs Are Important Summary NextBack Slide 42 1.) They make things, they help doctors and scientists, and they can be eaten for protein. 1.) They make things, they help doctors and scientists, and they can be eaten for protein. 2.) They are fun to look at under telescopes, they ruin peoples crops, and they store water in their backs. 2.) They are fun to look at under telescopes, they ruin peoples crops, and they store water in their backs. 3.) They are used for fertilizer, they attack big scary animals, they make honey and other foods. 3.) They are used for fertilizer, they attack big scary animals, they make honey and other foods. What Are Three Reasons Insects Are Important? Slide 43 Many bugs such as honeybees and silk worms make things. Maggots help doctors and scientists heal sick patients. Lastly many bugs can be eaten for protein! Great Job! Next Slide 44 While some people may think bugs are fun to look at under telescopes, thats not one of the reasons why theyre important! Bugs running crops is a bad thing, not a good, important factor. Lastly, bugs dont carry water in their backs. Nice Try! Back Slide 45 Those arent quite the reasons why bugs are important that have been given in this slide! Lets Try Again!
