Solids, Liquids, and Gases!

This week in science we learned about gases. The experiment at the end of the lesson was combining a liquid (vinegar) and a solid (baking soda) to make a gas (carbon dioxide). Mrs. Watson took us out to her front yard to do two different demonstrations.

If you want to try this at home, here are the things we used today:

In the first experiment, vinegar and baking soda were combined to blow up a balloon.  The students wanted to see a big reaction and thought it was a good idea to add extra baking soda to the balloon and extra vinegar in the bottle! The vinegar goes in the bottle and the baking soda goes in the balloon.  You can use a funnel to add the baking soda to the balloon.  Then you carefully put the balloon on the bottle and dump in the baking soda. Mrs. Watson didn’t get a picture of this.

For the second experiment, dish soap was added to the vinegar before adding in the baking soda.  Look what happened!

You can try this at home.  Experiment with adding different quantities of baking soda, vinegar and dish soap.  See what happens and post pictures to FreshGrade!

 

ADST Paper Chain Challenge

On Wednesday, the students were challenged to make the longest paper chain that they could using one piece of construction paper, scissors, and glue or tape.  Some students completed the challenge on their own, and others had family members join in on the fun.  The students had just over 10 minutes to make a plan and construct their chains. Here are a few screenshots from Zoom of the completed chains.

 

The longest chain was measured at 290 cm long. Wow!

 

School Science Fair

The K/1/2/3s worked very hard on their science fair projects this term. Each student chose a topic in January that they wanted to research. They started with their questions and wonders and then decided whether they wanted to do an experiment or a study.  The school science fair was Thursday and I think you will agree that the students all did an amazing job!

Cedar Inquiry

This term our inquiry theme is cedar.  We went down into our school forest yesterday armed with clipboards, pencils, keen eyes, and questioning minds to record the things we notice and wonder about the cedar trees (we had started this last week, but didn’t have enough time).

Here are a few of the students ideas:

Teddy-The leaves are close apart and far apart. Some of the leaves are dangling. Some leaves are longer than the others. I wonder why the leaves are so bendy. I wonder how the leaves attach and grow.

Kip-The leaves are flat on the cedar trees. The bark is flat and in little strips. The wood between the leaves iv very bumpy. The yellow cedar and the red cedar look different. The cedar cone is very bumpy and looks like waves.

Acacia-Red cedar has some red on it. One side of the leaves are lighter and the other side is darker. I notice dark and light in the cones. There are tiny white stripes on the cedar leaves.

Sinead- The inside is smooth and red and black, and a little bit of brown. I wonder how old they can get.

Clara-One side is darker colour and the other is lighter. You can count by the rings around to see how old the tree is.  One tree was 34 and another tree was 41.

Ruby-The green leaves are sort of scaly.

Cayden-The cedar leaves are green. Some are short and some are tall. Red cedar trees are tall. They are two colours: red and pink.

Ryder-Red bark smells neat. I notice:hard bark, tiny cones, and strong branches. How tall can they get? Are they good for houses?

Rylann-Cedar cones are small. They have stringy bark. On the top of the cedar bough it is dark and the bottom is lighter. On the top of the tree the trunk is small are it goes bigger and bigger to the bottom of the tree.

Lina-I wonder how many branches are on the red cedar tree. I wonder why moss grows on the trees. Why is the bark so rough? When you peel the cedar bark, underneath it is red. You can count the rings and it tells you how old it is.

Ayla-Cedar trees have little cones. Why does Old Man’s Beard grow on trees? I noticed that the cedar trees have long strong branches. How many cedars are there in the world? Why does green stuff grow on the trees? Why do the branches droop down? I noticed stringy bark. I noticed there was a pattern on the bark of green stuff growing then red cedar.

Joselyn-I noticed that cedar cones are tiny. I wonder where cedar trees grow. I wonder what the circumference is. Some trees are red like cedar trees. There are two kinds of cedar trees. I wonder how long cedar trees live.

Harmony-I see a square.  There are tow types of cedar: yellow cedar and red cedar. How many are there? I wonder why cedar trees have different lives? They have stringy bark. Another tree had scaly bark. I wonder why the cedar tree cone is small.  I noticed that on a cedar tree the branches go from bigger to smaller to smaller.

James-The branches are really long. I noticed there are lots of branches. They are very tall. They have stringy bark. I wonder how many types of cedar trees there are.

Dusda̱k̕wa Jam

The students finished their Berries Inquiry today with the making of dusda̱k̕wa freezer jam. The students worked in teams to gather materials and ingredients. First they had to mash the blackberries. They practiced their counting in kwak’wala as they did this. Each person got 10 mashes and then passed the bowl. Next they measured and added the remaining ingredients and got more counting practice as they stirred and stirred to dissolve the sugar. It was a lot of stirring!

 

Here is the video we use to practice our pronunciation. We are trying our best. Some of the numbers are tricky to say.

Tomorrow we are going to try our jam.

Dusda̱k̕wa Leather

Yesterday in science we did more work on our berry inquiry. We talked about how the First Nations people used berries. We learned that they ate the berries fresh or preserved berries so that they could enjoy them throughout the year. The berries could be dried in the sun or wind. We decided to dry our berries using a food dehydrator.

Before we started, we weighed the berries and then made estimates about what we thought the berries would weigh after they were dehydrated. Before dehydrating the berries weighed 1517g. We worked in teams to add berries, sugar, and lemon juice to the bowl. Then we took turns mashing the berries and spreading them on parchment paper.

We left the berries in the dehydrator for 24 hours. We weighed the Dusda̱k̕wa leather and were amazed to find out that the berries now weighed 444 g and had lost more than a kilogram of their weight.

Finally, it was time to sample our work. Everyone thought the Dusda̱k̕wa leather was delicious!

 

 

Science Fair

Just before Spring Break the students all participated in our school science fair. This is always a wonderful day where we get to share our learning with our friends, families and the community. The students have an opportunity to complete a study or experiment on a topic that they are interested in. Take a look at some of the fantastic projects below:

Great job, K-4s!

A Room Full of Inventors!

Thursday afternoon we let our imaginations run wild as we created our own inventions. We brought in the big cart of materials for the first time this year and boy was it fun! There were so many odds and ends to choose from and we also got to use the glue guns and the Little Bits. Take a look at the fun we had!

Thank you Brilliant Labs!

Last Friday, we got a very special package in the mail!  You may remember that in  the new year our class won a prize from Brilliant Labs for participating in the Hour of Code.  We got to choose $2000 worth of technology-based resources for our classroom. When we opened the box we found Makey Makeys and several Little Bits kits (the Lego Wedo is still to come).

We have spent two afternoons exploring the Little Bits kits and brought out one of the Makey Makeys this afternoon as well. We started with some of the suggested projects in the manuals, but then did some inventing of our own.

We would like to thank Brilliant Labs for this amazing prize and can’t wait to share our learning with everyone!

Q’uen-Thank you so much they are awesome!

Melliah-Thank you for the stuff you bought us.  We had a lot of fun with it.

Sierra-I made an invention with it.  I put the finger sensor at the end and the roll wheel think in the third spot and my battery before it.  I pressed the wheel and the vibration sensor bounced around.

Owen-I really like how you got us all of these parts.  I think I am going to try and change the calendar into a keyboard.

Kaydan-Thank you for this awesome stuff.  I made something called a Wiggle Light.

Alexandra-It was very nice of you to give us all these fancy things.

Ava-I really like the invention that I made.  Thank you for giving us them.  I made a really cool invention with Alexandra.  I gave her the other light so she could make two lights.

Cherish-I really like them.  I like the pressure sensor.

Science Venture

UVIC Students from the Science Venture program visited our school again this year.  Meera and Morgan presented workshops to the K-3s and the 4-7s.  The primary workshop was called Force and Motion and the intermediate workshop was all about weather.

In our class we went on a force and motion picnic, and learned all about forces and friction.  The students had fun exploring the friction boards and they all got to make helicopters to take home.
