Interactions Guide Objectives

This guide’s quiz has four questions; one matching each objective.

Species Interactions

List positive, negative, and neutral forms of community interactions, including specific examples of predators, herbivores, and types of competition; define symbiosis, including examples of mutualism, parasitism, and commensalism; and provide examples of symbiosis found in the Willamette Valley. 

Animals

List and describe basic characteristics shared by animals; explain what a vertebrate is and the lineage of vertebrates over time; and list the basic characteristics of fish species and describe the structure of fish scales. 

Invertebrates

Provide examples of annelid invertebrates; describe what scavengers, detritivores, and decomposers consume, including why they are significant to other species; and provide examples of organisms commonly found in soil communities. 

Insects

List the characteristics of arthropods and provide examples of crustaceans, insects, and arachnids; describe the basic structural characteristics of insects; and name several insect orders, including representative insects in these orders.

Guide 2A Journal Assignment #5

Introduced in the Species Interactions section of this guide:

Journal Page #5: Gall Description

Note: if available, we may provide oak galls for this assignment; you can sketch, label, and describe either oak gall or rose gall interactions for this journal page.

You will be providing a rich description of the gall, including a sketch, labels, and explanatory text. You can also include a photo screen grab from the video, if desired.

Select a view from the video and sketch the gall. Label the part that is the plant scar, and where the insect larvae are located. Also include a brief explanation of this type of interaction, including how the participating organisms are impacted (benefit, harmed, or no impact).

We are also providing videos of rose galls found in the Willamette Valley (see below).

You are turning in a journal page that includes:

a labeled sketch of a gall that includes the plant and where the larva are located.
a description of the gall interaction, including what type of interaction is occurring and the impact on both participating species.

Guide 2A Journal Assignment #6

Introduced in the Animals section of this guide:

Journal Page #6: Animal Reflection

Journaling, whether on paper or on a device, gives the brain an opportunity to recall what it has learned over time. Unfortunately, education is usually so rushed, we often don’t spend time reflecting on what we already know.

On this journal page, you will be writing about two animal experiences you have in your lifetime. The first is your earliest memory of an animal. It could be a pet, a toy, an animal in a movie, etc. Many famous researchers point to childhood nature experiences as their motivation to pursue science education.

Your second reflection is to choose the animal you would most want to research if you were a biologist, and to try to recall where you previously learned about that animal. It could be from a movie, a class, someone’s story, a combination of sources, etc. Sources of science learning can be varied and unexpected, and motivating to pursue further learning experiences.

Include in your journal page reflection:

your earliest memory of an animal.
the animal you would want to research and where you learned about that animal.

Journal Page Directions

To be completed after taking the quiz on Canvas.

Upload your two journal pages to Canvas. If the file is really large, it may help to host it on a webpage and submit the web link to reduce upload time.

All three assignments are due by Wednesday 11:59 p.m. P.S.T. Once you have taken the quiz on Canvas and uploaded your two journal pages, you have completed this guide.
