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!
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!
In JK we’ve been very busy preparing for Chanukah!
We’ve been reading, crafting, singing, and practicing our lines and our dance for the Family Chanukah Celebration. We explored light with some of our translucent dreidels and other toys on our light table, and we had our third visit from our Grade 4 reading buddies! Keeping busy!
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!
