Aquatic Sampling<\/em><\/figcaption><\/figure>\nActivity: What’s swimming in your stream?<\/strong><\/h4>\nObjective:<\/strong> Discover biodiversity by observing freshwater insects and other macro invertebrates.
\nScience Skills:<\/strong> Observation
\nLife Skill:<\/strong> Communicating, record keeping<\/p>\nPreparation Activities:<\/strong>
\n\u2022 Collecting and looking at resource books
\n\u2022 Make an Observation Log
\n\u2022 Making a Kick Net (see Stream Assessment Guide)<\/em><\/p>\nWhat You Will Need:<\/strong>
\nNets, kick net, white bottomed dish pans, magnifying glasses, rulers, pads, pencils, sample jars, squeezable sports bottle, turkey-baster and\/or eye dropper.<\/p>\nActivity:<\/strong>
\nCheck \u201cIt\u2019s All Connected\u201d for a list of publicly accessible streams known to currently support freshwater insects and other macro invertebrates.<\/p>\n1. Plan a day to visit one of these locations.<\/p>\n
2. Read over and discuss Safety and Ground Rules<\/strong> with youth before your exploration.<\/p>\n3. Fill out observation logs:<\/p>\n
a. Describe the Habitat: Observe the water. Is it clear or cloudy, cold or not so cold, moving fast or barely moving at all? If you have a photographer, photograph your location.<\/p>\n
b. Natural defenses: ask the youth to make guesses about where the bugs might be, how do they use their environment to protect themselves?<\/p>\n
4. Fill a white dishpan or similarly sized container with some of the stream water. Also fill a squeezable sports bottle with some stream water.<\/p>\n
5. Follow the collecting and sampling instructions in the Stream Assessment Guide.<\/p>\n
6. Have each youth select a different aquatic insect, and continue diagrams and observations in their observation logs.<\/p>\n
a. Method\/Speed of Movement: How do they move around the dishpan ? If you add some small rocks or sticks to the dishpan do they cling to them? Many insects cling tightly to the rocks in the fast moving water. Notice their body shapes. How would their body shapes help them live their lives? Are their bodies still or do some of the insects move their bodies in place?<\/p>\n
b. Food\/ Method of Ingestion : All aquatic macro invertebrates need to absorb the oxygen that is dissolved in the water.<\/p>\n
7. Offer resources to help them identify and name their insects and macro invertebrates.<\/p>\n

Teachable Moments:<\/strong>
\nSome insects need a lot of oxygen and can only survive in very healthy streams with little pollution and lots of oxygen. Others can thrive in relatively polluted conditions. Scientists study samples of aquatic insects like the one\u2019s you\u2019ve collected to learn about the overall health of a stream.<\/p>\n![\"Mayfly\"](\"https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2093\/2020\/03\/mayfly.gif\")
Mayfly<\/figcaption><\/figure>\nMany aquatic insects have gills on their bodies. For example, most mayfly nymphs have visible gills on their abdomen (the part that looks like its tail)<\/em>, and they sweep their abdomens from side to side to absorb more oxygen from the water.<\/p>\n![\"Stonefly\"](\"https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2093\/2020\/03\/stonefly.gif\")
Stonefly<\/figcaption><\/figure>\nStonefly nymphs have bushy gills where their legs attach to their bodies, stoneflies will bob their bodies up and down (as if they were doing push-ups)<\/em> to absorb more oxygen.<\/p><\/div>\n<\/div>\n<\/p>\n
