Tornado Tube

• Procedure
• Fill a plastic soda bottle about two-thirds full
  of water
• Screw one end of a tornado tube onto the bottle.
  Make sure the end fits tightly. Then screw an
  empty bottle into the other end of the tube.
• Turn the bottle with the water in it upside down.
  Hold on to the tornado tube. Quickly move the
  bottles in five or six circles so that the water
  inside swirls.
• Which way does the air in a tornado spin?

Investigation Review

  where it rains almost every day.
• What a contrast to the _________ which can also
  be very hot, but where it rains hardly at all.
• Farther north the _________ ________ grow. There
  the winters are cold but the summers are warm and
  wet.
• Even farther north you find coniferous forests
  and the _____ where the subsoil stays frozen all
  year.

35
Caddisfly Larvae

• Larvae measure up to 3/4 inch in length.
• Three pairs of legs.
• Body is caterpillar-like and strongly curved.
• Antennae reduced and inconspicuous.
• Color varies from bright green to dark brown.

36
Mayfly Nymphs

• Can take from three weeks to two years to become
  adults.
• Nymphs of many species vibrate their gills to
  increase the amount of water moving over them
  (this is the equivalent of panting). Their gills
  may also be used as swimming paddles.
• Adult Mayflies have male and female sexes, but in
  some species the females can lay unfertilized
  eggs (without male interaction) that hatch into
  more females.

37
Stonefly Nymph

• Adult Stoneflies live only for a week to a month,
  and females live longer than males.
• Stonefly nymphs have two long tails or cerci
  (sir-key), whereas Mayfly nymphs have three long
  tails. The cerci are sense organs but also help
  the insect to move.
• Stonefly nymphs have tubes of thread-like gills
  on their underside, wing pads and antennae
  (feelers).
• Each leg has two claws that are used to cling to
  rocks or sticks.
• Their bodies are streamlined so they don't get
  swept away by the water current.

38
Dragonfly Nymph

• It breathes by sucking water into its abdomen to
  move water over its internal gills. Once it has
  absorbed enough oxygen, the nymph squeezes the
  water out rapidly so it does not have to come up
  for air like most pond insects. This also helps
  propel them forwards in the water.
• Much of a dragonfly's life is spent in the larval
  stage where it moults six to 15 times. The nymph
  crawls out of the water and moults one last time,
  emerging as an adult with functional wings.
  Dragonflies and damselflies do not go through a
  pupal stage to become an adult.
• They keep the populations of mosquitoes and flies
  under control.

39
Midge Larvae

• Midge Larvae can tolerate organic pollution as
  they feed on the organic particles. They can live
  in water having low levels of dissolved oxygen as
  they can rise to the surface to breathe.
• Even a drop of water is enough to sustain a Midge
  Larva.

40
Rat Tailed Maggot
The rat-tailed maggot usually breeds in drains,
sewage pools, and other stagnant water. Although
the larvae live on decaying organic matter, they
must breathe air. For this, the breathing tube
(the tail) is extended or contracted depending on
the depth of the liquid in which they are
feeding.
