Trout Hatching Project

Last week we received our rainbow trout eggs from the Oregon Dept. of Fish and Wildlife. The eggs originated from the Roaring River fish hatchery near Scio, Oregon. It did not take the eggs long to hatch. We were greeted this morning with two incubators full of 500 smiling alevins (trout with egg sacs attached) and all seem to be doing well. Over the next month students will study how trout (and other organisms) survive in ecosystems as¬†how organisms’ external structures their functions help aid survival. More pics coming soon!

Understanding Cause & Effect Relationships in Ecosystems

Last week we began a study of ecosystems. Our students analyzed photos showing different population phenomena, as well as components in a food web, and identified resulting cause and effect relationships. This week students engage in some online ecosystem simulations and analyze the results. Students will be focusing on two essential questions throughout the unit:

  1. How does a system of living and non-living things operate to meet the needs of the organisms in the ecosystem?
  2. How and why do organisms interact with their environment, and what are the effects of these interactions?

Reflex Math Program Trial

We are excited to pilot a 30-day trial online personalized learning math fact fluency program called Reflex Math Fact Fluency, which is intended to supplement our math instruction. Students will engage in the program at school 3-4 times a week. Students can also access the site home for math fact fluency practice using the following link:

Trout Observations

Today our students made observations about the structures and functions of the external features of rainbow trout. This is part of a larger unit on ecosystems, which has included students analyzing cause and effect relationships within food webs. Later this week we will receive rainbow trout eggs that will be raised in a classroom incubator, and our focus will shift to the role of trout in an ecosystem. Stay tuned for more on this project. Thank you, Mr. Koepke for donating the trout for our students to study!

Math Problem Solving

Our fourth graders are working hard on the math practices involving perseverance and precision. Last week the focus was multi-step problems involving interpreting remainders of division equations.

Final Bridge Projects

Bridge Unit Final Task: Create a bridge that spans a 10 inch canyon using only 20 pieces of 9″x12″ construction paper & pieces of masking tape. Bridges are then tested using a force sensor to see if they can withstand up to 60 Newtons. It is exciting to see evidence of all the students have learned!

Bridge Engineering

Students have spent December & January learning about different types of bridges. They built models of them, tested them, analyzed the strong/weak points of each type, and then wrote about their discoveries.
