  2. Barramundi Mould Grass Living and Growing Dogs Mites Germs Living things grow, change, and reproduce themselves

  3. Living and Growing DogsMites Germs

  4. Just like all mammals, dogs need a male and female to make puppies.

  5. Girls dogs can have puppies from 6 months old

  6. Girl dogs can have two litters of puppies every year. Click on the puppy to see what that looks like…

  7. Living and Growing Dogs Mites Germs

  8. What are Mites? • Mites are like little animals, like little ticks, but much smaller. • Scabies mites can cause scabies.

  9. This is a mite She is very small. .

  10. This is a mite. . She is very small. Let’s use a magnifying glass to make her bigger.

  11. This is a mite. . We can just see her! Let’s look closer under a microscope.

  12. Mange mite Demodex

  13. Mange mite Demodex

  14. Mange mite Sarcoptes

  15. How does Mange spread in Dogs?

  16. Mites can cause mange in dogs, and make people itchy too.

  17. Adult mites lay eggs This life cycle takes about 1 month. The baby mites grow up into adult mites. The eggs hatch, and more mites come out. Mange mite Sarcoptes

  18. Mites live in the skin. They make a dog itchy so they loose their hair.

  19. Mites make tunnels, crawling around under the skin.

  20. How does mange spread in dogs? Mange crawl using their legs…

  21. Mange mites can walk from one dog to another

  22. The drug wears offs and the mites crawl back on One dog spreads mange to others Treating some dogs doesn’t stop the problem

  23. The mange medicine kills the mites but doesn’t kill the eggs

  24. The mange medicine kills the mites but doesn’t kill the eggs

  25. The eggs will hatch making more mites

  26. Or use the mange medicine again So we need to get rid of the eggs before they hatch

  27. How can we get rid of eggs?

  28. We can get rid of eggs by cleaning out our houses and washing all the blankets

  29. Mites also don’t like the sun, so getting lots of sunlight on things like mattresses will help control them

  30. Living and Growing Dogs Mites Germs

  31. This is Mr Germ He is very, very small.

  32. This is Mr Germ He is very, very small. Let’s use a magnifying glass to make him bigger

  33. This is Mr Germ He’s still too small to see! We’ll need a microscope.

  34. How is he moving? This is Mr Germ under a microscope.

  35. Let’s look closer.

  36. He has little legs called cilia.

  37. His tiny legs move him tiny distances.

  38. Oh! What is he doing?

  39. Mr Germ split in two.

  40. Mr Germ reproduced himself.

  41. Germs can reproduce very quickly.

  42. Germs can reproduce very quickly.

  43. Germs can reproduce very quickly.

  44. 19 - 18 - 17 - 16 - 15 - 14 - 13 - 12 - 11 - 10 - 9 - 8 - 7 - 6 - 5 - 4 - 3 - 2 - 1 - Let’s make a graph to see how fast germs reproduce. On the bottom we measure how much time has gone by. On the side we can measure how many germs we have. IIIIIIIIIIIIIIIIIIIIIII 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110

  45. 19 - 18 - 17 - 16 - 15 - 14 - 13 - 12 - 11 - 10 - 9 - 8 - 7 - 6 - 5 - 4 - 3 - 2 - 1 - What do you think the graph will look like? Like this? Then like this? Or maybe like this? Let’s find out… Let’s find out… Time (s) That would mean there are less germs as time goes on. IIIIIIIIIIIIIIIIIIIIIII 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110

Plasticine isn’t alive, so it won’t grow, but it splits just the same way. Time (s) IIIIIIIIIIIIIIIIIIIIIII 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 100 105 110
