Larger the Vibration, Louder the Sound!

Larger the Vibration, Louder the Sound!

The latest science unit the 3Js have started is on Hearing and Sound.  After reviewing that sound is vibration, we did demonstrations to show that smaller vibrations created softer sounds, while larger vibrations created louder sounds.  Check out our lesson today!

3D Solids! Making, Naming and Analyzing

3D Solids! Making, Naming and Analyzing

Our class has been looking carefully at 3D solids in math, recognizing and naming them by using their base shapes, as well as identifying how many faces, vertices and edges they each have.  Today students got a chance to make their own choices of solids using a variety of materials.  Take a look at how … Continue reading

Getting Creative with X & ➗

Getting Creative with X & ➗

Every morning the 3Js have a Morning Math Meeting, and without a doubt we love creating our very own math sentences with a target answer the most.  Over the past week and a bit, our class was formally introduced to multiplication and division, although we’ve been “dabbling” with it all year. Today we continued to show … Continue reading

Towers in the Wind!

Towers in the Wind!

In our “Testing and Building” science unit, students were given a challenge to use what they’ve learned to design and build at tower that was at least 70cm in height.  It not only needed to be stable enough to stand on it’s own, but to stay standing while there was a wind blowing on it. … Continue reading

Measuring Perimeter!

Measuring Perimeter!

Last week in math the 3Js were focusing on perimeter of larger areas, and they had a project to complete.  Groups of 2 or 3 had to work together to estimate, measure, calculate and record the perimeter of 2 different rooms or hallways around the school.  After they were done, groups that measured the same area … Continue reading

The 3Js are 100 Years Old!

The 3Js are 100 Years Old!

  It was 100 Day at IREC today, and the 3Js did a writing project to surmise what they would each be like when they were 100 years old.  Ms.J aged pictures of them using a photo app, and students added them to their own writing projects.  Below is a slideshow of their projects, as … Continue reading

Leadership Awards in 3J!

Leadership Awards in 3J!

Two of our 3J students received IREC Leadership Awards today! Carden was recognized for showing leadership when he seeks first to understand, then to be understood.  Carden is careful to make sure he understands project directions, and asks very good questions that helps everyone in the class. Heather got an award for showing leadership when … Continue reading

Measuring Time!

Measuring Time!

Estimating and measuring time is an important skill to have!  The 3Js practiced that today using pendulum timers they made.  As a class we came up with several different tasks to complete.  They estimated how many pendulum swings each would take, then actually measured them and ranked them from fastest to slowest.  Finally student groups … Continue reading

Constructing & Testing Bridge Design!

Constructing & Testing Bridge Design!

Over the past couple of days, the 3Js have been busy building bridges, testing the strength of each design, and discussing what they learned.  Student teams each built a beam bridge and a truss bridge, then created a screen cast explaining what each looks like, how they made it, and which one they think will be … Continue reading

Bridge Designs

Bridge Designs

The 3Js have begun a new combined science unit focusing on testing materials and designs and building.  We started out with examining bridge designs: looking at examples and what made them weaker or stronger. Students had a lesson introducing several types of bridges, we shared our schema (a surprising amount!), and learned about some design characteristics … Continue reading
