Separating Mixtures


Science: I can test a variety of household materials; I can investigate the states of matter.

Today, Ms Dool lead us in our first Chemistry experiment! We have learned so far about the states of matter, reversible and irreversible changes, and different types of mixtures (homogeneous and heterogeneous). Today, we got to make mixtures and then use different tools to try to separate them. 


Each group was given a category of mixtures (solid & solid, liquid & liquid, or liquid & solid). We got to choose the materials from a whole pile that Ms Dool had (like jello powder, blocks, screws, dirt, milk, gatorade, etc). Then, we could choose our tool to try to separate (like a sieve, magnet, coffee filter, or other liquids). 



"We had soap and milk. When we stirred it, they mixed it. The soap kind of 'took over' the milk; it turned orange. We tried to separate it with the eye dropper and the milk got sucked up easily." ~ Lillian


"We made a mixture of vegetable oil, water, and soap. We weren't able to separate it."
~ James & Lawrence

"We took milk and pudding mixture and made pudding. 
Then we added Gatorade and the powder went to the bottom." ~ Seb C, Leo, Liam


"We made coffee! We mixed ground coffee with gatorade. We tried to separate it with a coffee filter and it worked pretty well. The Gatorade turned brown and smelled like coffee." ~ Vance, Jane, Enzo, Sadie


Here are some of our quotes from today's lesson: 

"I used a magnet to get the screws out, then a sieve to sift out the dirt." ~ Maria
"I used a sieve to sift out the marshmallows and my fingers to pick out the blocks." ~ Oscar
"I liked what we were doing because we got to mix things, which was super fun; we got to see the end result of what we were making, and I just found it fun trying to separate things in different ways." ~ Vance
"It was really fun. We got to use a lot of weird materials and tools. I like mixing stuff a lot." ~ Lillian
"I liked creating all the mixtures and seeing what everybody else did." ~ Liam
"I liked mixing it because the soap floated to the top. When I put my hand in, it was really slimy." ~ Hazel
"It was really messy!" ~ Lawrence
"I found if we kept it on a tray, it wouldn't spread all over." ~ Oscar
"I liked making the pudding because we poured the milk in the cup and the mixture into another cup and it turned from white to yellow." ~ Seb C
"Chemistry was super fun because we got to experiment with different materials." ~ Seb K
"Sometime, Chemistry can smell good!" ~ Leo

Chemical Changes!

Science: I can explore household substances; I can use the scientific method to answer a question: I can design a fair test. In class, we have been learning about Chemistry and Matter. This week, we have been learning about physical and chemical changes. A Chemical Change is when there's a change that creates something new and a Physical Change is when its appearance changes but it's still the same substance.  Five clues that a chemical change has happened are:  Bubbles form  Heat is released Light is produced There is a colour change A smell is produced An example of a Physical Change would be changing States of Matter: An ice cube melting to water Yesterday, we put baking soda in a balloon and mixed it with vinegar to see what would happen. The balloons inflated. It was fun to watch them. When you mix baking soda and vinegar, it creates carbon dioxide (CO2) gas. They expanded because of the increase in carbon dioxide gas. We know the molecules, when they turn int...

Catapult Building!

Image
Science: I can explore simple machines; I can test designs and materials and make changes to see improvement Yesterday in class, we learned how to make catapults out of materials like: popsicle sticks, elastic bands, egg cartons, and hot glue. This relates to simple machines because catapults are levers, and we have been learning about simple machines. Here are some student learning reflections:  "I learned how to (1) build and (2) we made a type of lever." ~ Vance "I learned a bit more of self-control when you are getting angry because the elastic bands would not go over the one part and I was super frustrated." ~ Callie "I really liked this creation we did because you can build so much things from popsicle sticks and elastic bands and it was really fun." ~ Dillon "Me and Kimberly made a double catapult!" ~ Suzi "It was really fun testing out the catapults because I could practice on my friends and they wouldn't get hurt because we were...

Story Writing

LA: I can describe story elements; I can produce fiction texts; I can use feedback to revise and edit work; I can use what I know about words to spell new words The Very Cranky Bear outline For the past few weeks, we have been working on writing short stories. We first discussed the elements of a story (Setting, Characters, Problem, Solution, Theme, Climax, and Resolution). We then related this back to the chapter books we've read this year and other short picture books Ms Elder has read to us. We even watched a Brainpop video that talked about this "pyramid" structure, called " Freytag's Pyramid ." It's the same structure ancient Greeks used to use. Ms Elder showed us a simple format to follow where the main character(s) try to solve the problems three times, unsuccessfully, before they finally solve it. We noticed that many simple picture books, like The Very Cranky Bear and Little Blue Truck follow that same model. We practiced as a class and in p...
