This week in Science we performed several experiments with water that explored its property of cohesion. Cohesion means that water molecules are attracted to each other which makes water droplets tend to stick together. Because of cohesion, there is surface tension at the surface of water, and we were able to do all sorts of neat tricks with the water because of the unique property of this liquid!
Our class has been busy experimenting with various liquids this week since we started our new unit on Exploring Liquids on Monday. There are a lot of hands on experiments to conduct, and the students have already had lots of fun learning about different liquids and their properties. In this unit, we will be learning how to:
Keep an eye out for more of our experiments on liquids over the next couple of months, and watch the videos below if you'd like to keep up with some of the concepts we're learning in class and see 2B's slow motion liquid race!
Two of the learning outcomes in our Science unit on Hot and Cold Temperatures involve the students' understanding of insulation and how it keeps materials hot or cold. The class has had fun looking at real-life insulators this week in Science, and wrote about different insulation facts using the iPads this week. We definitely need effective insulators in our cold winter weather!
We are enjoying our science unit on hot and cold temperatures in 2B! Some highlights have included baking potatoes to see how materials are altered with temperature changes, measuring temperatures with thermometers, and examining how heat rises. The students observed the differences between raw and cooked potatoes, and discovered that raw potatoes smell like potato chips and French fries (you can watch the video below to see how heat is used in the making of potato chips). If you’d like to review the outcomes of this unit, you can take a look at the ten outcomes in the slideshow below!
Not only are we learning all about hot and cold temperatures in our class, but we can also portray temperatures using colour! We learned about warm and cool temperatures in Art last week, and you can see your child's winter snowflake that we painted using cool colours (such as purple, blue, and green) on Seesaw!
With the arrival of colder weather and snow this month, we’ve started a new unit on Hot and Cold Temperatures in Science. We've been exploring different uses of thermometers, learning about different temperatures, and comparing the high and low temperatures from day to day. In this unit, we will be learning:
Stay tuned for our further learning about hot and cold temperatures!
We were very lucky to have a distinguished guest, Dr. Jeffrey Newton from the Alberta Science Network, visit our class today and teach us all about magnetism! He brought in a variety of very interesting materials, along with demonstrating and involving us in a variety of experiments. We have now wrapped up our learning on magnets, and the students are officially magnet experts!
In Science this week, we explored different magnets’ north and south poles, which materials are transparent to the magnetic force, different magnetic devices, and examined magnetic fields. The students enjoyed making a temporary magnet with a nail, and used various devices to view the effects of invisible magnetic fields. Stay tuned for our upcoming magnetic device project!
A big highlight so far this month in 2B has been the start of our unit on magnetism in Science. We've been exploring what materials are attracted to magnets and which are not, and observing the effects of magnets on a variety of items. In this unit, we will be learning:
Later in the unit, students will be asked to construct a toy or game that uses a magnet at home. Stay tuned for more details about that project, and for our further learning about magnets!
We’ve really been enjoying playing Breakout Edu games this past week to review our learning in grade two this year. The Breakout box is a student-friendly version of breakout or escape rooms where people have to solve puzzles to escape the room. In our Breakout games, the students had to use their knowledge from math, science, and social studies to solve a variety of clues that unlocked the locks on the Breakout boxes (which contained small prizes). So far the students have beat the timer on all our Breakout Edu games, which is no doubt a testament to both their knowledge of not only these subject areas, but also their problem-solving, communication, collaboration, and critical thinking!
