It’s that time of year again when we do our part to help another batch of salmon eggs hatch and make their way to Rough Bay Creek. We also get a chance to learn about the salmon and how they are important to the environment.
Erin visited the school today and talked with us about the Salmon’s life cycle, the job of the hatchery, how we can help the salmon, and about a salmon’s life in the wild.
Here are a few of the interesting things we learned:
Sharon-The fish food doesn’t smell that good.
Jacob-I learned that the second stage in the life cycle is called the eyed egg.
Brooklynn-I learned that in the ocean they are silver and when they are in the river they are brown striped.
Bronwen-I learned that there are lots of predators like bears and birds.
Lily-I learned that when they first turn into fry they have this line down their belly from where their yolk sac used to be.
Jorja-I learned that the last stage is called an adult salmon.
Kezra-I learned that the fish food can rot if we feed them too much.
Taegan-I learned that if the fry are in shade under trees the heron and other birds won’t be able to get them.
Solomon-I learned that you can’t drop them really high into the water.
Rhys-Sharks can eat salmon when they are in the ocean. When the salmon grow up they can go in the ocean. Salmon can hide in the rocks.
Kaydan-THey swim in the ocean.
Lainey-Salmon need to breathe in the water.
Merissa-They like dark water.
Teagan-They stay in the river for a year and a half and then they go in the big ocean.
Today after lunch we put on our walking shoes and warm coats, and headed off for Neptune. No space shuttle was required because we shrunk the whole solar system down to a more manageable size.
The Sun’s actual diameter is 1,391,980 km, but for this demonstration we used a 20cm playground ball. In the video it is very hard to see Mercury, Mars, and Pluto because they are all being represented by the head of a pin.
Our walk helped us to imagine just how enormous our solar system actually is!
Did anything in our video surprise you?
Do you have a favourite solar system fact you can share with us?
We continued our study of plants today by dissecting seeds. Almost half the class was away today and so this post is a way to share our discoveries with our friends who were sick.
First we completed an anticipation guide full of interesting statements about seeds. We had to decide if the statements were true or false. Try a few for yourself (you can find the answers at the bottom of this post):
T F 1. All plants produce seeds.
T F 2. The outside covering is called the seed coat.
T F 3. Some seeds can wait two thousand years before they begin to grow.
Next, we made observations after looking carefully at dried lima beans and ones that had been soaked over night. We compared the two and tried to predict what the inside of the seed would look like.
Finally, we carefully dissected the seeds identifying the different parts and discussing their jobs.
Here are a few of the cool facts we learned today:
Jenny-If the seed coat doesn’t break the plant won’t grow. Some plants grow very quick. The seed needs its food supply. Fay-The seed coat won’t break unless the seed gets enough water to expand and break out. Some seeds can wait up to 2000 years before they begin to grow. The seed needs water and the right temperature to grow.
Silkence-The seed has a coat so that it will be protected from disease and insects. There is an embryo inside the seed. The embryo looks like a big pokey thing. Ana-A seed needs to have water and if it doesn’t it won’t grow.
Dante-The food supply is almost the whole lima bean. Justin-It needs the right temperature in the ground to grow.
Niall-Seeds have their own food supply until they can make their own food. Jordan-The lima bean has all the food it will need until it can grow and then it will make its own food. The temperature has to be right for the plant to grow or it will die. Plants can grow very, very slow. The lima bean has a little curve at the top of it and you can see the root growing.
Quang-The lima bean had a lunch pack just like the baby salmon did so it can grow. Oceana-If you put a lima bean in water overnight it will expand.
How did you do with your predictions?
(Questions 1,2, and 3 are all true)
Have you ever looked closely at the inside of a seed?

We started the morning off by dissecting flowers. We looked for all the different parts and tried to figure out what each part was for. Here are some of the interesting things we discovered:
Kennedy-When we took the petals off we could see the stamen Niall-Inside the stem looked hollow Lily-Inside of the stem there were little veins for transport Sahara-We looked inside the stem and it was really gooey
Justin-We used magnifying glasses to have a closer look Karin-We eventually cut the whole flower off to see the eggs
Ana-There were many, many, eggs Jenny-The colourful petals attract the bees
Oceana-When you rub your fingers on the anther you get pollen on your fingers Silkence-The stigma on top of the pistol felt sticky so the pollen from the bees will get stuck Dante-I learned all the parts of the flower
You can take a closer look with us by watching our slide show.
Dissecting flowers was the perfect introduction to a Georgia O’Keeffe inspired art lesson. Mrs. Watson brought in beautiful flowers for us to use as our inspiration. We hope you like them!
The last group finished filming their Common Craft video on Friday. This was a wonderful learning experience for everyone. We learned how to brainstorm ideas, create a story board, make Common Craft style props, and work together to plan out individual jobs. It took a lot of practice to get our timing just right and to make our videos interesting by using expression when we narrated the action. We think making videos in the Common Craft style is a great way to share information.
We hope you enjoyed Group 5’s video. If you missed any of the other groups you can watch their videos by clicking on the links below. Group 1 and 2 Group 3 and 4
This week we are making Common Craft style videos to show what we learned about the water cycle. We worked hard in our teams to plan our videos, write our scripts, and make all the pieces we would need. We learned that timing is very important and that we have to use expression when we narrate the action. The hardest part was timing the narration with the moving of the pieces in and out of the scene.
Today was an absolutely amazing day! We were extremely excited to be participating in our first science fair. We worked very hard on our projects and it was wonderful to have the chance to share them with our friends, our families, and the judges. Mrs. Watson was so proud of us and the judges commented on how excited we were about science and how fabulous we all did. We are already thinking about projects we might want to do next year!
Here’s a peek inside the science fair:
A closer look at our projects:
Congratulations to Sahara, Niall, Justin, and Silkence, in grade 3, who will be going on to the Regional Science Fair next week. Three grade 2’s, Sophie, Mia, and Nola, will also be taking their projects to display (judging is only for grades 3-12 at the Regional Science Fair). The whole class will be attending the Regionals next week to support our classmates and to see all the amazing science projects from the other students in our school district. Look for a post about the Regionals next weekend 🙂
A special thank you to the judges for helping to make today so special and to our parents for all their support!
Have you ever participated in a science fair before? What was your project?
Grade 2/3’s, what project ideas do you have for next year?
The 2010-2011 school year was proclaimed as the Year of Science in our province. In January our whole school participated in an online science quiz to launch the Year of Science challenge. The three schools with the highest participation in the province would win their choice of a laptop or an audio system. Our school was one of the top three schools and today, at our school science fair, we received our brand new laptop, speakers, mouse, and other goodies. We can’t wait to put it to good use!
Today we had a very special visitor in our school! A scientist from from Port McNeill came to share his love of science with our students. Steve showed us some really cool experiments and let us try them out too. We love science and especially love the chance to get a little messy!
Don’t forget always ask questions!

We also found out that we will be having a science fair at our school at the end of March. This will be our first science fair and we are very excited.
Do you have a favourite science experiment?
Have you participated in a science fair before? We’d love to hear about your project!
