Week of May 6th

In Science this week we started our new Unit on Mattter. We are beginning to discover that everyday materials around us generally fit into one of three categories: solid, liquid, and gas. Along with plasma, these three categories represent the different possible states of matter. A table is solid, while the air we breathe is a gas. Some materials can even transition between the different states. For example, water can exist as a solid (ice), a liquid (water), or a gas (steam or vapour). 






On Friday, we had a fun lesson that explored the properties of “oobleck” – a simple mixture of cornstarch and water. Oobleck is unique because it can behave as both a solid and a liquid.

We discovered that Oobleck acts like a liquid when poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands.

Oobleck gets its name from Dr. Seuss' book Bartholomew and the Oobleck where a gooey green substance, oobleck fell from the sky and wreaked havoc in the kingdom. The students had the chance to experiment with this great material and explain their rationale regarding what state of matter they feel Oobleck belongs to. 

Gooey Messy fun was had by all!!

A big thank you to all of our volunteers who joined us for Aggie Days this week. The students had a wonderful time learning all about the agricultural climate in Alberta and gaining an appreciation for the hard work that it takes behind the scene to provide food for us to eat.  In Math this week was to learn how to skip count to divide. We discovered how to skip count on a number line, skip count using our fingers and that we can divide by sharing the total number of items and the number of times in each set.  To use a number line we considered, what number is being divided? (20) How can you tell from the picture? (20 is where the arrows end) What number are we dividing by?(4) How can you tell? (4 is the size of the jump) So, what is the answer to 20 ÷ 4? (5) How can you tell from the picture? (the number of arrows)    We also discovered that skip counting can be performed by  keeping track of the number of times you skip count, using fingers. For example when s...

Hurray!! Run and Scream!

The students were so enjoying this game called- Run and Scream as we celebrated National Indigenous People's Day. This is a fun example of a traditional indigenous game that was played to see who has the best stamina. In this game the c hildren would line up, take a big breath, and start running fast while screaming until they ran out of breath . The spot where they had to draw their next breath was marked. With each turn, they tried to better their own distance and pass the marks of others.  They had such a kick out of it that they have asked me several times to post the short video on our blog!!!  Have a great summer everyone:) and thank you for all of your support this year. We had a fantastic time!!! Kindest regards, Sabine Harris

Week of May 20th

This week and last, we  revisited  our unit on Data analysis . We  spent time reviewing how to read and interpret information presented  in the form of  pictographs, bar graphs,  line graphs, and line plots . We  learned how to analyze the data presented in the graphs to solve one- and two-step word problems . We  discovered how to use multiplication skills to find the numbers represented on these scaled graphs . As  a class, we collected data about a topic that interested us and created our bar graphs . In  the following week, we will compare all four types of graphs and solve story word problems with the information on the charts.  Our fraction unit is also coming to a close this week. In our unit, we started with paper folding . We  began learning what a unit fraction is and learned the denominator in a fraction is the number of equal parts in the whole  and  the numerator is the number of shaded or selec...
