Ecology 2 - Food Webs

Based on the website

This discussion begins with a review of how energy transfers through food webs and then engages students in assembling a food web with a small set of ocean organisms.

5. Identifying Forces

Given seven drawings depicting motion, students will be able to correctly identify, describe, and indicate direction and relative magnitude of three to five forces in each.

4. Types of Forces

Given a textbook passage on forces, students will be able to organize the passage's information into a graphic organizer and teach the information to other students.

Brains and Neurons

How does a brain - less than 3 pounds of wrinkly pink matter - enable a person to sense their environment, think, feel, make decisions, remember things, and control every behavior? This is one of the greatest mysteries of life. For teachers interested in teaching students about the brain and its neurons, here is a set of lesson plans for exploring your brain.

Ovulation Calendar

I used this to show my students what happens during menstruation. I have them fill out where the flow is, when ovulation happens, when the lining begins to shed, and when are the prime times to have sex for fertilization (or the prime times to avoid sex!) 

I included readings about what happens during menstrual cycles. 

Teaching electron configuration

In response to a question on ways to teach electron configuration to students, here's a model I used with my 8th graders. We had been using beans to represent and build 2D models of atoms (green lentils = electrons, white beans = protons, black beans = neutrons). I made a handout for them to help them understand the idea of where electrons like to go when they are added (download it at the bottom of this page).

Magic School Bus: at the Waterworks

While I was reading The Magic School Bus,they went inside a cloud. Because this is not a field trip, there should be no driving into clouds :). But in Inside a Hurricane, They make a water cycle experiment.
