Taking Action

Students use the net they make to dip macroinvertebrates at or below the surface. The flat side of the net allows pressure on the substrate so that organisms do not escape under the net. Two students hold onto the handles and submerge the net until the bottom edge is on the substrate. They should hold the net in place. A few other students enter the water upstream of the net and walk downstream, kicking the substrate to dislodge organisms which the current carries into the net.

I am a first year homeschool mom. I found Lesson Planet and was impressed with the amount of resources that are available online! I have been able to find content that was age appropriate and relevant to the areas my 3 kids are studying. And knowing that these are plans created by teachers makes me confident in presenting the material to my children.
