Today the students learned about ‘alien’ plants in Portland and how these plants can lead to monocultures in our woods and erosion problems. The four invasive plants we focused on were Himalayan Blackberry, English Ivy, Herb Robert/‘Stinky Bob’, and Garlic Mustard. The students had some great questions about how to get rid of these plants and were excited to hear that there are ‘ivy pull parties’ at Tryon Creek (the next Stewardship Saturday Ivy Pull is November 12th from 9am-12pm).
The students also played the erosion game ‘Just Passing Through’ where each team got to be raindrops, plants, or stones on the slope near the school. The raindrops had to work hard to race down stream with out getting tagged by a plant. They even had a chance to play the pollution game (the raindrops tried to pick up chips that represented chemical or natural stream pollutants and ‘deliver’ them to the river with out being tagged by a plant) before we were hit with real raindrops!
This last Saturday we had a wonderful tour and hike at Hopkins Demonstration Forest. The students were able to help measure trees, count pine needles on different types of conifers, and hand drill a hole into a tall fir to tell the age and how fast it was growing.
If you are interested in learning more about sustainable forestry, they offer Community Forestry Days on the 2nd Saturday of each month where you can be part of the action in the forest.

Today the students learned about the different ways we use a forest. They played the ‘Forest Appreciation Team Relay’ where they learned about the forest consumers (people in recreation, people and jobs, people and products, and animals and the Earth) and the benefits that each group takes from the forest (hiking, ranger, lumber, clean water, etc). It was great to get outside, work as a team, and race to find their consumer’s benefits! The students also sorted items collected from my home that were man-made or came from a plant/tree. You can try this game at home, searching each room to find objects from the plants or the forest.
The students finished their mason bee nest and these can be installed at your home by trying some rope or string between the two side nails and mounting it on a fence within 100 yards of the plants that you would like pollinated in the spring. It is best to face the nest east to catch the morning sun and place it at least 1 yard from the ground. These native bees are small, nonsocial, and nonaggressive; you may only notice that they are around if you find holes blocked with mud by the end of spring. You child is welcome to decorate their nest but it is not recommend to stain the wood as those chemicals may discourage the bees from using it.

They had also a chance to drill holes into a wood block for their mason bee nest. These bees are small, non-aggressive insects that are very important pollinator of native plants. The students will finish their nest at the next class (Oct 24th) and will be able to bring it home to hang in your yard. If you would like more information about how to make a mason bee nest, I have uploaded the directions we used to Google Docs:

This week the students learned about the basic tool of field scientists - observation. They became aware that sometimes we miss important details when only using our eyes, missing the smell of the Japanese Glorybower leaf or the texture of the fringecup leaves. As you notice leaves together this week, ask your child to describe the leaf’s texture, shape, edges, and thickness to you. If you don’t have time outside, try to explore your house using your senses with your kids - a field scientist can make observations anywhere! I have uploaded three observation forms to Google Docs that you can use with your young scientists:
- Leaf Observation.pdf - table to record sight, touch, hearing, and smell observations of leaves
- Leaf Observation Venn Diagram.pdf - compare and contract observations of two leaves
- Observation game.pdf - similar to the ‘phone call’ game played in class; use descriptive language to get your partner to match your pattern
The students also heard the story of Dr. Geerat Vermeij, a man who was blind by the age of four and is now a world-renowned professor of marine ecology and paleobiology through his study of shells using mostly his sense of touch. If you would like to learn more about Dr. Vermeji you can find his biography ‘Privileged Hands: A Scientific Life’ at the local library or go to this kid-friendly site:
Next week we be walking to Stephen’s Creek Natural Area for our first outdoor field study. We will go rain or shine so please have your child dress appropriately. They will be learning to identify native plants, which ones produce nuts/fruit that are safe to eat, and which ones not to touch!

Introducing the EcoThink Science Enrichment Program
Are you interested in learning how a field scientist works? Do you know which plants in our neighborhood are native, which are invasive, and which are safe to eat or touch? What is ‘Growing and Green in Oregon”? To find out, sign up for Rieke’s fall after-school science enrichment program. We will meet on Monday afternoons - Sept 26, Oct 3, Oct 10, Oct 24, Oct 31, and Nov 7 (no class Oct 17). Two optional field trips have been planned to learn about ethnobotany (Tryon Creek State Park) and sustainable forestry (Hopkins Tree Farm).
This is a six week, hands-on unit where each week builds on knowledge and experiences from the previous week as we explore science topics in our theme ‘Growing and Green in Oregon’. The program does involve several hands-on projects that require adult supervision. We encourage parents or grandparent participation so if you are available for one or more of the sessions and would like to contribute your time, please let us know. There will be a 20 student limit so sign up today! For more information, contact email@example.com

Ecothink Lesson 4 – Recycling and Reuse
This week we focused on Recycling and Reuse. The students created a square for the International Plastic Quilt Project and played the Garbage R’s game (recycle, reduce, reuse, reject, or rethink). Please take some time to review what your child learned during the club meeting and check out these websites with them.
Try going to ‘Recycle City’, a website from the EPA
This site has several recycling games and activities for rainy weekends or summer projects:
Cut down on your junk mail at
Have your child find the catalogs that you don’t want and located the customer numbers on the labels to help you opt-out of mailings.
Take the ‘Trash and Climate Change’ challenge
Cut down on baggies use and make a sandwich wrap out of recycled items:

This month we focused on Waste Out of Place and we conducted a lunchroom trash audit. Our results will be posted soon.
If you have a chance, challenge your family to the ‘home trash audit’ to calculate how much waste do you produce in a day. Do you produce more or less than the national average of 4.6 lbs of garbage a day?
Please take some time to review what your child learned during the trash audit and check out some or all of these websites.

March Late Start Morning Field Trip
We had a great time exploring Tryon Creek State Park with Ranger Karen and Ranger Christal. The kids learned about the importance of fallen trees, searched for 'nursery' logs, and delighted in finding the animals that lived under them. We even were able to see a Great Horned Owl nest and deer tracks.

Styrofoam Drive and Recology Tour
Here are our pictures from the Rieke, Hayhurst, and Bridlemile Styrofoam Drive on Feb 5 and 6 and Rieke's tour of the Recology Processing Plant.
We collected 60 cubic yards of styrofoam that will be recycled instead of headed to the landfill. We collected enough styrofoam to fill one of our modular classrooms to the ceiling - that's 660 pounds of styrofoam!
