We learned lots and had lots of fun today at Telus World of Science! We got to watch the Thermal Theatrics demonstration on the science stage which tied in perfectly with our unit on hot and cold temperatures, and we participated in the Splish Splash program led by our science expert Derek which culminated our class' unit on Exploring Liquids. We also got to explore a number of the exhibits in the facility thanks to our four wonderful volunteers!
We had a week with lots of Science learning as we focused on how all living things need and contain water, the water cycle, the threat of pollution to accessing clean water, and a review of our learning so far. You can see the students poster PSAs about water conservation (like the ones above) on Seesaw!
In this Science recently the students had to plan a waterproofing solution for some pretend placemats that we were planning for our prospective (pretend) Millgrove Restaurant. The students set to work testing out different solutions to our restaurant's problem. They found that wax crayons and rubber cement made the paper waterproof, but felt markers and pencils did a poor job. We recommended that the restaurant use the wax crayons because customers likely wouldn't want their lunch tasting like rubber cement!
We also examined different densities of liquids, and the absorbencies of different materials. We found that corn syrup is very dense, while cooking oil has a very low density. We also discovered that sponges are extremely absorbent, while nylon fabric, plastic wrap, and tinfoil are extremely poor absorbers. 2B would certainly suggest using a sponge rather than tinfoil to clean up a spill!
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!
