Persuasive Writing: Should Gum Be Allowed in Schools?

Do you chew gum? Have you ever stepped in gum? Last week, our writers explored whether gum should be allowed in schools. We discussed the PROs and CONs of chewing gum, including:

-studies have indicated that chewing mint flavoured gum may help with alertness and fatigue

-some psychologists and teachers believe that gum helps increase focus and reduces anxiety

-gum can be used as a ‘fidget’ for kinetic learners

-gum can be a huge problem in terms of litter and clean-up

-gum is not environmentally friendly since it is made of plastic/rubber like substances

-gum is dangerous because it can be unsanitary and spread illness

What do you think? Our writers are responsible for defending their opinions.

Skittle Science: Investigating a Theory

Yesterday, our class investigated the theory/conspiracy that all Skittles are actually the same flavour. Many people believe that all Skittles are the same flavour, but we perceive them as tasting different because of the colour and scent of the candy!

We tried to prove or disprove this theory by doing a few experiments. First, we tasted the Skittles normally (our control).

Next, we tried tasting the Skittles while removing our sense of smell (plugging our noses). We noticed that the taste of the Skittles was reduced dramatically, because our senses of smell and taste are very connected!

Finally, we tried closing our eyes and guessing what flavour we were eating. Some people believe that your brain automatically associates a colour with a flavour (ex: yellow = lemon flavour).

What do you think? Is this theory accurate? Or just an internet rumour?

History Mystery: The Sinking of the Titanic

Hello, historians! Our class has been investigating the mysterious fate of the ‘unsinkable’ ship… the RMS Titanic. So far, we have examined the lack of lifeboats, the treatment of 1st class and 3rd class passengers, and some of the engineering feats and flaws of the ship.

Tomorrow, we will begin to explore some of the main people involved in the Titanic (and her untimely tragedy).

Feel free to refresh your memory or share what you’ve learned by clicking on our PowerPoint below!

Virtual Aquarium Visit: VR Videos

Hi, marine biologists! Check out these VR (virtual reality, 360 degrees) videos of some aquariums around the world! Remember, also be mindful to take what you see online with a “grain of salt” (meaning, use your best judgement to tell if something is accurate).

These videos work best on a mobile device or tablet.

Such a Good Boy by Marianna Coppo

Today for Brain Breakfast, we read Such a Good Boy. In the book, a very well-behaved dog decides that he wants to ‘let loose’ for the first time in his life. He rolls in the mud, barks at cars, smells garbage, and has an amazing time just being a dog. We discussed how sometimes, we all need to take a break from trying to be perfect.

Check out the video below of another dog deciding that he just wants to have fun (during an agility challenge at a dog show):

Reindeer Toothpaste Experiment

Our class created our own version of the famous ‘elephant toothpaste’ experiment! To do this experiment at home (with adult permission and supervision), you can…

-fill an empty plastic bottle or cup around 1/2 way with 3% hydrogen peroxide (if using a higher %, please wear gloves and eye protection)

-add a large squirt of dish soap

-optionally, add food colouring and/or peppermint extract

-then, in a separate cup mix a large spoonful of instant yeast with some warm water for 30 seconds (until dissolved)

-quickly and carefully pour the yeast mixture into the hydrogen peroxide mixture and step back

We learned this experiment creates and exothermic reaction, which means it gets hot! We noticed that when we increase the amount of soap and yeast, the bubbles continued to form for a much longer amount of time.

Pleases note: Always be careful when doing Science at home, and make sure to have adult supervision and permission.

Micronation 3-D Models

We have been hard at work creating our 3-D Micronation models! Take a look at a few of the completed projects so far! Our class has created their own individual ‘tiny countries’ that have their own flag, identity, economy, and topography. I’m looking forward to seeing the rest of these models completed!

Candy Cane Day: A Science Experiment

Did you know candy canes were thought to have been invented around 200 years ago? In celebration of Candy Cane Day at Lochdale, we decided to take these minty treats and use them in a Science experiment!

First, students decided what substances/chemicals to submerge the candy canes in. We had a selection of acids, bases, etc. Then, we observed the candy cane immediately, after 5 minutes, and after 20 minutes of being submerged in the liquids.

We had very interesting results! You can also check out the process of making candy canes by hand in the video below:
