Science Is So Dramatic!

Published by under Science

We’ve been learning about Landforms in our Science class and have been learning a lot of new Science vocabulary. It’s not always easy to remember,

so we decided to have a little fun and act out some of the vocabulary words. Here is what we captured…

Have You Heard of a Sea Monkey?

Published by under Science

If you haven’t heard of a Sea Monkey, you’re not alone. Sea Monkeys, also known as Brine Shrimp, are tiny crustaceans that need salt water to hatch and survive! We have been studying them recently in our Environments unit in class. We were trying to find out what their range of tolerance was in various concentrations of salt water, as well as their preferred environment in which to hatch. We found out that…

1. Out of 4 cups of water, ranging from 0 spoons of salt to 3 spoons of salt, the Brine Shrimp seemed to hatch the most in 2-3 spoons of salt.

2. Their range of tolerance was 1-3 spoons of salt.

3. No shrimp hatched in 0 spoons.

Something else that is interesting is the fact that Brine Shrimp do NOT like very salty water, so you won’t find them in oceans or seas, only salt water ponds and lakes.

Take a look at our video below which captures a live Brine Shrimp swimming under the microscope! Cool!

Nurseries of the Earth

Published by under Science,Sustainability

Our class trip to the Mangroves in the BangPu area of Bangkok was a real eye-opener for many of us who’ve never seen mangroves before. It was a beautiful day, not too hot by Bangkok standards, and we were paired up with Mr. Lam’s class to learn all about the mangroves.

In groups of about 8, we were led by some wonderful conservation specialists who guided us around the protected mangrove area. We played some interesting games that made it easier to understanding what is happening to the mangroves right now such as cutting them down for firewood, shrimp farming, industrialization and so on. We made a ‘mangrove in a box’ and got to see how mangroves actually protect houses and people from destructive forces such as tsunamis.

A tranquil glimpse into a bird’s life in a mangrove was another stop along the journey, complete with binoculars! I heard a few students say they could have stayed there all day. The cool breeze that blew through the building as we watched the birds in their natural habitat was very inviting and welcomed!

We also learned about food chains and how the mangroves are a critical part of maintaining certain bird and other animal species. Check out this article highlighting our need to care.

According to https://www.sms.si.edu/irlspec/Mangroves.htm, mangroves perform a vital ecological role providing habitat for a wide variety of species.  Odum et al. (1982) reported 220 fish species, 24 reptile species, 18 mammal species, and 181 bird species that all utilize mangroves as habitat during some period of life.  Additionally many species, though not permanent mangrove inhabitants, make use of mangrove areas for foraging, roosting, breeding, and other activities.

And Mangroves just aren’t in Bangkok, of course. They are all over the world! Do you live in an area of the world that has mangroves?

Check out the student blogs from Room 230 and read up on their take on the mangrove field trip experience!

We’re Flipping Out!

Published by under Science

As part of our Science unit on Variables, we are currently doing an investigation called Flippers. Today, we were learning about how different variables that we apply to our Flipper system may affect how far an object (ie. aluminum ball, cork stopper) is launched.

Check out two groups’ recent videos below to see what this looks like!
Then click on individual student blogs to see what they have to say about their learning!

Science Reflection: Planes

Published by under Science

Dear Gr.5s,
We have wrapped up our investigation with planes! Please take some time to reflect in the following ways in your science journal:
– What would you say were your group’s successes? What worked well for you?
– What were your group’s challenges?
– What were the results of your group’s experiment?
– Looking at your graph, were the results surprising, or predictable?
– any other comments

I look forward to reading your reflections next week!
Miss B.

Science Videos–Lifeboat Inquiry

Published by under Science

These class videos show us investigating how many passengers (Thai baht) will fit into our “lifeboats” (paper cups cut to different sizes). This is part of our Science unit on variables.

Pendulum Pandemonium

Published by under Science

Have you ever heard of a pendulum?  We are studying a unit on variables and we’ve started by investigating pendulums aka “swingers”.  We’ve learned about what variables may affect a pendulum’s number of swings in 15 seconds. We explored:

1. changing the mass of the pendulum bob (we used Thai baht coins)

2. changing the release position

3. changing the length of the string

What variable do you think would affect the number of swings in 15 seconds??
