Success!

It worked! We were so excited to come into the classroom this morning and see the final results. We noticed that the purple wasn’t quite purple and upon further investigation, we found that the paper towel coming from the blue cup was not touching the bottom of the empty (purple) cup. We theorized that had it been touching the bottom, we would have gotten a better result. We also noticed that the water level lowered in the red, yellow, and blue cups and theorized that it must have travelled through the thirsty paper towels into the empty cups, and that is how the colours mixed. That also changed the colours of the paper towels, which is something we didn’t think would happen!

As we conducted our experiment, we followed the scientific method, below, which is posted in our classroom. Let us know if you repeat the experiment at home, and what results you got!

C is for…

COLOURS!

Today we started to explore colours, as our letter of the week is C. We reviewed the colours in Hebrew and we learned their names in English and French. We watched this video about mixing primary colours (until 3:02) and then made predictions on our chart to show what we think will happen in our “walking rainbow” experiment.

Let us know how it goes if you try it at home! We have to leave our experiment overnight tonight because it hadn’t quite finished by the end of the day. Check out the photos of our progress!

Stay tuned!

Fusion Power!

This morning we had the pleasure of a visit from Mr. Josh Ray in our classroom instead of going down to the maker space! We started investigating the states of matter and how to change them. Today’s topic was “melting” and we remembered that there used to be a TON of snow and ice on our playground and then it melted because hot temperatures are here! Our activity is creating a masterpiece using our many skills. To name a few: fine motor, 1 to 1 correspondence, matching, patterning, and… PERLER BEADS!!!

We’ve still got a lot of work to do on our creations before we fuse (melt) them together (with high temperature!) but here is a sneak peek:

Happy Chanukah!

Today we made some beautiful unique marbelized invitations for our Chanukah show tomorrow evening! If you’re interested in the process and the science, please click here. We learned about the miracle of the ‘shemen’ (oil) on Chanukah, why shemen (oil) does not mix with mayim (water), and experimented with different kinds of paper that we called ‘thirsty’ (watercolour paper) and ‘not thirsty’ (cardstock). We also celebrated the first day of Chanukah with some singing, candle lighting, and window decorating. A very big TODAH RABAH! to Ivri’s family for bringing us a beautiful chanukiyah and some lovely candles!
Happy Chanukah!

    

Magic Fizzy Dinosaur Eggs

This morning we got to hatch a fossilized dinosaur egg. It was made out of baking soda, water, and food colouring. We helped the egg dissolve by pipettes and vinegar, and found a T-rex fossil inside! Then, we got to make our own dinosaur eggs and hatch them! We used our 5 senses to check out all of the ingredients – except taste because that would be yucky – and throughout the reaction.
(Listen with the sound on.)

 

We had so much fun! If you’d like to repeat the experience at home, here is the link to the experiment.

Dinosaurs

Today we listened to the story “Dinofours It’s Snowing!” by Steve Metzger. The dinofours are dinosaurs that are four years old, just like us! We were inspired by the footprints that they made in the freshly fallen snow in the story and we created our own dinosaur footprints using our classroom toys and some paint. Check out our awesome work! 

 

If you’d like to listen to the story again at home, here it is! Enjoy!

 

RESULTS!

Here is what we observed and what we now know about what happens to snow when we bring it indoors:

  • when the snow melts, there is less water than there was snow. That’s because the air spaces between snowflakes dissapear when the snowflakes melt!
  • at the bottom we found sand, gravel, and dirt – ewww! This is why we should not eat snow! (Unless it is falling from the sky directly into our mouths)
  • red snow becomes red water
  • the snow outside didn’t melt and that’s because it’s still very cold outside.

We are now headed out to repeat the experiment! Enjoy your day!
