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 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!
We learned lots and had lots of fun today at Telus World of Science! We got to watch a special presentation in the Zeidler Dome, and we participated in the Splish Splash program led by our science expert which tied into our class' unit on Exploring Liquids. We also got to explore a number of the exhibits in the facility thanks to our five wonderful volunteers!
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!
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. We learned about the science of how snowflakes form, and how at different temperatures the crystals form different shapes and sizes. As we've learned throughout this science unit, temperature has a big effect on things both big and small!
This past week in Science we’ve been focusing on heating systems (namely forced air, water, and geothermal), and insulation. We learned about insulation used in buildings to keep them warm or cool depending on the season, and examined various types of insulation that animals use to brave the weather. Mrs. Leblanc gave us a fascinating tour of our school’s heating systems, and the class really enjoyed seeing the inner workings of Millgrove! You can watch the video below to see how people take advantage of animal insulation to keep themselves warm!
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 making homemade ice cream. 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). We learned that milk loses heat relatively slowly, which meant that we had to shake our cream and other ice cream ingredients for a while before it turned into ice cream! If you’d like to review the outcomes of this unit, you can take a look at the ten outcomes in the slideshow below.
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!
2B was a flurry of building and experimenting this past week as we built and unveiled our magnetic devices for our grade one buddies. It was neat to see the variety of ways in which magnets can be used practically, and the students did some excellent scientific problem-solving in the creating of their devices. The highlight was when the grade one students visited our class to test out our creations. Needless to say, the students of 1V had lots of fun with all the toys and games! Check out the video above to see the students’ creations.
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
