Overview:
MACRO INVERTEBRATES you can see with your eyes, and MICRO INVERTEBRATES, you have to use a microscope.

Research:
Websites like these, where they have all of the animals in their Taxa groups, are extremely useful during research. You can always search for one invertebrate and find a website with all of them.

This is our material list we had for the activity and our demo day presentation. Although you probably will not need all of these things for your project, it is a good example of how to make a material list in excel. We did not have to spend any of the school’s money, and the few things we needed to buy were so cheap that we decided to spend our own money.


Material list FOR SURVEYING:
  • · Net
  • · Data Sheets
  • · Clipboard
  • · Pencils/Pens
  • · Clock
As mentioned above, most of the books you read claim you need things like forceps and collection tubs, but those things just weigh you down and are unnecessary for our stream .

Step-by-Step Instructions:

  1. Gather the necessary materials
  2. Go to the beginning of the stream and document the conditions on a fresh data sheet
  3. Start your survey.
  4. When you find an invertebrate, make sure you have proper identification and document it on your data sheet.
  5. Repeat this process every 50 yards-there should be purple/blue markers around 3ft. tall made of 1” in diameter PVC pipe every 25 yards.
  6. To find the cumulative value of the stream, count each DIFFERENT animal you see, so if you find >50 sow bugs (which you probably will) all of them still get one point.
  7. for Taxa Group 1, you multiply times 3, for 2, *2, and for 3, *1

This is a copy of the data sheet we used during our stream survey. This one was made by us in excel, but you can always go online and find one too.

Demo Day:

We used this day to educate our visitors on macroinvertebrates and stream health.

What we talked about:
  • · 3 Taxa groups
  • · Sampling
  • · Methods/ recording
  • Our data and health of the stream


For our activity we got 3 white tubs with different and or similar macroinvertebrates and we let the visitors identify and record them on our data table. After they were finished we would have them tell us the total index value and overall stream health according to macroinvertebrates.
