Broccoli – Aphids – Lacewings & Parasitoids - People
Broccoli
is a delicious vegetable that people love to eat! It is often attacked by aphids. We can use
pesticides
or rely on the other insects that attack aphids. If the aphids are not kept in check, there won’t be very much broccoli
.
ACTION:
If you have lots of aphids, you are a small broccoli. If you have only one aphid, you are a large
broccoli! If your are small broccoli, curl up and be small – LARGE BROCCOLI BE BIG!Slide2

Broccoli– Aphids – Lacewings & Parasitoids – People
Aphids attack lots of plant that people eat, including broccoli. Aphids have mouths that are like pointy straws; they stick these straws into the plant tissue and suck the juices out. A couple aphids are OK, but having a lot of aphids on a plant will damage it.
ACTION: If you are an aphid, make needle like mouth parts like a straw and find some broccoli to drink!
If you are not attacked by lacewings and parasitoids, multiple to many aphids. But if you are attacked by lacewings and parasitoids, you are just one aphid. Slide5

Broccoli – Aphids – Lacewings & Parasitoids – People
Lacewing
larvae are insects that eat other insects. As adults they have lacey wings, which gave them their name, but as larvae they don’t fly. They walk around looking for prey. Once they’ve found it, they stick their pointy mouth parts into their prey and suck all the juices out.
Parasitoid wasps attack aphids. They, like other parasitoids, lay their eggs inside aphids. The larvae then eat the aphids from the inside out and pop out like aliens. Parasitoid wasps are vital in controlling aphid populations.
ACTION: If you are a LACEWING, take your pointy mouth parts and go chew on an aphid! If you are a PARASITOID, go find a host aphid to lay your eggs in. Slide8

Apples – Bumble bee – Parasitic bee - Decomposers - People
Apple
flowers need to be pollinated in order to make apples. Bees often do that pollination. In fact, animal pollinators like bees are responsible for 1/3 bites of food you eat.
ACTION: Hold up your arms as branches, and find
a bee to make apples! If you can’t find a bee, hold up the picture with no apples.Slide14

Bumble
bees are excellent pollinators. Unlike the European honey bee, the most widely known pollinator, bumbles bees are native to North America. Bumble bees are mostly larger than honey bees. They are often black and yellow and fuzzy.
ACTION: Buzz around until you find the apple tree!
P

its flowers so that there will be
apples. Take the pollen back to your nest to feed your baby bees. Slide17
BUMBLE BEESlide18
Apples – Bumble bee – Parasitic bee - Decomposers - People
Kleptoparasitic
bees lay their eggs in other bees’ nests. This takes advantage of all the hard work the other bees’ have done, like collecting pollen to feed to their baby bees.
ACTION: Sneakily buzz around and find a bumble bee
to follow back to its nest and lay your
eggs. Hold up the bee picture. Make sure the bee doesn’t see you!
If you can’t find
a bumble
bee,
sit down quietly. Slide19

Springtails
are decomposers. They eat leaf litter and other things decaying on the ground. Decomposers keep the planet from being covered in dead material. There are more of them when there is more to eat.
ACTION: Scout around on the ground, and find
the apple tree to eat the decaying apples that have fallen to the ground. If you find apples, hold up the picture of many springtails. If you don’t find apples, hold on the picture of the one springtail. Slide21

Fish – Mayflies – Water - People
Immature
mayflies are called nymphs, and the live in the water. Nymphs of most species feed on
algae
and decaying things in the water; some species have
predatous
nymphs, which eat other insects. Although with stoneflies and caddisflies, mayflies are an important indicator of the ecological health and water quality of a stream.
ACTION:
Find the river and
s
curry
around underwater collecting food!Slide29
MAYFLY LARVASlide30
Fish – Mayflies – Water - People
After feeding
as larvae underwater, mayfly adults emerge. Adults from one species in an area will emerge mostly on the same day, creating huge clouds of mayflies. They mate and the females lay their eggs on the surface of the water.
ACTION: Find the larval mayfly and then fly away on your new wings. If
you can’t find the mayfly, you have nothing to eat
so sit down quietly. Slide31

Mayfly nymphs help keep water clean. In fact the presence of mayfly nymphs indicates a healthy river ecosystem.
ACTION:
If a mayfly nymph find you, you are a clean river. Flow like a river and hold up the
picture of clean water. If no mayfly nymph finds you, hold up the picture of algae covered water. Slide33

People domesticated cows well over 4000 years ago. They are raised for meat and dairy. Cows evolved to eat grass. In order to get good quality meat and dairy, cows need lots of grass.
ACTION: Find
the grass and eat it! If there isn’t much grass, you don’t produce any milk. Slide39

Cows - Grass - Dung - Dung beetles - People
Grass is an important plant for people. It feeds many animals we like to eat and makes pretty lawns and soccer fields. In order to grow well, grass needs to have plenty of nutrients and light. In a cow pasture, a lot of nutrient comes from cow poop that is recycled back into the soil, sometimes by dung beetle.
ACTION:
If there is only one
cowpie
, the beetles have been doing their job and the grass is
healthy. Grow lots of grass and hold up the picture of the healthy, green
grasss
!
If there are many
cowpies
, the grass isn’t getting any nutrients or light and it’s growing well. Hold up the picture of the sparse grass. Slide42

Cows cannot digest all parts of the grass they eat. The
indigestible material comes out again as cow poop, and cows poop a lot! In cowboy language these are called
cowpies
.
ACTION: Plop down behind the cow! If
a dung beetle is around, it will find you.
Start by holding up one

Dung
beetles eat dung (feces) from other animals, including cows. They find the
cowpies
, roll pieces of them up into balls and bury the balls in
holes to feed their babies.
This helps
removed
the
cowpies
, which could smother the grass,
and
it helps recycle
the nutrients to the grass.

Find the
cowpie
and process it! (Roll it into a ball and bury it)Slide48
