1. Tool that detects dissolved oxygen. 2.
Calculator used to keep track of dissolved
oxygen. 3. Plug it into calculator. 4. Now your
ready to test with your tools.

1. Manual dissolved oxygen kit used. 2. Stick the
tube in with stream water. 3. Let the tube rest
there for a few seconds. 4. Compare the tubes
with other examples.

Dissolved Oxygen results
Its not surprising the most oxygen was found in
the riffle, because thats where oxygen enters
the streams.

Nitrates
There were no nitrates found in either the riffle
or the pool.

1. You need to use a graphing calculator. 2. Plug
it into the port of the calculator. 3. Now you
can use the tool Josh is using while swimming
with his boo.

Velocity (manual)- tools used
We measured out 10 feet with the tape measure
(left), and dropped the noodle material in the
water (orange, right). We timed how long it took
to travel the 10 feet and thats how we got the
velocity manually.

• Autotrophs
• Organisms that produce their own food.
• An example are plants that get their energy from
  the sun

• Heterotrophs
• -Are organisms that eat other organisms
• -Some examples are humans, animals, etc.
