Thanks to the District 279 Foundation Grant program, the Bell Museum Exploradome will visit Weaver Lake Elementary today and tomorrow. Every third, fourth, and fifth grader will have a chance to enjoy a program about space! Thanks, District 279 Foundation for making this great learning possible!!!
Hello, Weaver! I saw an article this morning in the Star Tribune, and just had to post it! It made me think of all the work our fifth graders do to learn about native Minnesota bee species. Honeybees are not native to Minnesota and some wonder if they out compete our native bees. What do you think about our human impact on the planet? What are you doing to make a difference? I just had a good friend send me a package of stainless steel straws so that I can stop using single use plastic straws. It's not a big step, but I am happy to make even a small difference in our impact on the planet! I bet you have lots of good ideas for how to do that too! Do you carry a re-usable water bottle? What other simple changes can we make?
Third Graders met a Barred Owl Today!!!
If you already know about Barred Owls, you know how special they are! For many of us, they are best know because of their distinctive call: “Who cooks for you? Who cooks for you-all?”
My favorite adaptation by far are their lovely brown eyes. We have seen this bird a few times in our school nature center, and every time it stops me in my tracks.
To learn more about them, check out the link to the Cornell Lab of Ornithology to the left! Of course our third grade ornithologists are also a good resource. It's possible they also dissected an owl pellet recently . . .
At Weaver, we always love to learn more!!
Family Engineering Night
Will you be there?
Thursday, February 1st, 2018 - 5:30 - 7:30.
Students, please bring a grown-up with you!
The Great Backyard Bird Count
From February 16-19, Weaver Scientists and Engineers can be part of the annual Great Backyard Bird Count (GBBC)!
You don't just have to count birds in your backyard! You can count birds in the park, your school, or anywhere birds are found! The GBBC is a project of the Cornell Lab of Ornithology, the National Audubon Society, and Bird Studies Canada.
If you choose to participate, all you need to do is:
- Count birds for at least 15 minutes. Count longer if you want to!
- Report your bird counts using the checklist on the GBBC website by clicking on "Submit Observations". You can also use the free eBird Moblie app to submit counts.
How great to be a part of Citizen Science!!!!
Deep Look Videos by PBS
Have you heard about the underwater tape of the Caddisfly! Our fourth graders study macroinvertebrates. They can tell you all about adaptations! This Deep Look video explains the underwater tape of the Caddisfly. Check it out here!
Today is the Winter Solstice! Have you heard about the Sun Stop that occurs this month?
By keeping track of sunrise and sunset times, we notice that days get shorter before the solstice and lengthen after the solstice. We also notice that length of day barely changes for about a week before or after the solstice.
The word solstice means just that, sun stop! The sun appears to stop moving, but what is really happening is this:
- The sun begins to set later a couple of weeks before the winter solstice.
- The sunrise doesn't begin to get earlier until two weeks after the solstice.
As the second graders explained to me today, "This is because the Earth's axis tilts!" They are right, but it is also because our planet enjoys a slightly elliptical orbit.
Imagine what we all know just from watching and noting sunrise and sunset times! it's pretty amazing when you think about it!
Did you know that bees are attracted to the color blue?
Scientists have discovered that some flowers create a blue halo to attract bees. They learned that bumble bees can see the halos! To learn more, check out this article!
If you have been wondering about gardening for pollinators, one thing to consider is providing plants that bloom throughout the entire growing season. As climate change impacts bloom times and temperature, there are increasing periods of time where pollinators lack a food source. In some cases, spring flowers complete their blooming period long before summer perennials have caught up, cutting off a supply of pollen and nectar early.
As the Xerces Society notes:
"On the other end, an unusually warm October and strong winds this fall have left many monarchs stranded in their northernmost range. Not only will these monarchs need late blooming sources of nectar to maintain their strength until they are able to fly south, they may not be able to find enough late-season food sources along their migration route to fuel their flight back to Mexico."
You might also be interested in this Insect Flight video!
Dragonflies and bees move their wings very differently in flight. Here we can see in slow motion the way the bee and dragonfly wings beat in a 90 degree different direction with the same result flight!
Smoky Winged Beetle Bandit Wasp
What do you know about wasps? Most people know they have the potential to sting, but did you know that they help control insect pests, pollinate plants, and provide food for other wildlife? Really, wasps are pretty tame unless captured or bothered. Fifth graders at Weaver study bees, and likely know that bees and wasps are related. While bees get protein by collecting pollen, wasps are predators. Because they are predators, they can protect crops and gardens by eating harmful pests. One particular wasp, the smoky winged beetle bandit wasp (Cerceris fumipennis) hunts the Emerald Ash Borer. Scientists are using this wasp to help protect ash trees in Minnesota!

Hello, Weaver! Tonight is our STEM in Action Fair! November 9, 2017! I look forward to seeing you between 5:30 p.m. and 7:30 p.m. to share your great work!
I also want to note that tomorrow, November 10th, is World Science Day for Peace and Development. How amazing to think that some day your science or engineering work will contribute to the peace and development of the world!
We are proud to announce that Weaver Lake Elementary has been named a 2017 Magnet School of Excellence by Magnet Schools of America (MSA), the National Association for Magnet and Theme-Based Schools.
Weaver Lake Elementary: A Science, Math and Technology Magnet School provides a dynamic, inquiry-based learning environment for students in grades K-5. Weaver Lake’s program incorporates value-added, hands-on activities that focus on problem solving, analytical thinking skills, and are based on real life experiences. Our integrated project-based, thematic approach to teaching has increased academic growth in all areas. Community partnerships have enhanced student learning experiences. The young scientists, mathematicians, and technologists at Weaver Lake Elementary are a community of learners that continually Inquire, Discover, Explore, and Achieve—the big IDEA at Weaver Lake is to become lifelong learners.
“Magnet schools throughout the country are being awarded for their excellence in demonstrating student achievement, innovative and engaging instruction and curriculum, community engagement, professional development, and a commitment to diversity. This is a competitive process that awards only a small fraction of the magnet schools nationally. Schools that win our Merit Awards represent the best in education, innovation, equity and opportunity for all students in our nation.” says Magnet Schools of America Executive Director.
To receive a merit award MSA member schools must submit a detailed application that is scored by a panel of educators. There are two categories of merit awards: (1) Magnet Schools of Excellence, the top award given to a group of select magnet schools, and (2) Magnet Schools of Distinction, the second highest award of recognition.

Project Lead The Way is Here!
We are so excited to be starting Project Lead the Way at Weaver Lake! All grade levels are participating in PLTW engineering units. Fifth graders are exploring programming VEX IQ robots and kindergartners have new engineering opportunities tied to fairy tale stories. As we grow in our PLTW expertise, we look forward to adding more engineering opportunities throughout the curriculum.
I am sad to say that the current news about Monarchs is a bit dismal. There are frequent updates on their status at Journey North. Here at Weaver Lake, we are watching them closely. If you are wondering how you can help, please consider planting milkweed. Resources are available to make this easy. Currently there are about 20 milkweed species available as seed, though the availability varies based on location. Some nurseries also sell milkweed transplants or "plugs." If you are not sure where to find milkweed locally, check out this Milkweed Finder courtesy of the Xerces Society to locate a supplier near you.
