The Grade 5s are excited to lead our Advent liturgy at Saint Brigid on Wednesday, December 21st this year. We are beginning to rehearse for this event this week.
Today in Religion class we began to brainstorm some special
actions that we can take during this Advent season, to brighten someone else's day.
As a class, we are going to be writing Christmas cards to deliver to those
within the community. Students are encouraged to brainstorm some other special
actions we can do as a class during the remainder of Advent. There is a field trip form that will come home this week, for when we walk around the
community and deliver the Christmas cards on Wednesday, December 21st.
In Science class, we kicked off our Classroom Chemistry unit by experimenting with different ways to separate solids in a mixture. We know that a mixture can be described as two or more substances that keep their original characteristics when they are combined.
We tested four methods to separate solids from a mixture:
- Magnetism - items that are magnetic will attach to the magnet.
- Buoyancy - solids that float will rise to the surface of the water.
- Strainer/Sieve - larger solids will remain on top of the sieve, while smaller particles will fall through.
- Funnel - smaller solids will be able to pass through the funnel while larger ones will not.
Next, we created lemonade from water, lemon juice, and sugar. We tasted the mixture before and after adding in the sugar, and learned that by stirring the sugar in, we were able to create a solution. A solution differs from a mixture because it describes when one substance dissolves into another, and we are unable to distinguish the properties of each individual substance.
Once we created a solution by stirring the sugar until it dissolved, we then experimented with various ways in which we could separate our solution. We made a hypothesis (an educated guess) about two different methods to separate the sugar from the lemon juice and water. The first method we used was evaporation where we required heat to remove the liquid from the mixture, and the second method to separate a solution included our pouring the liquid into a new cup, through a coffee filter. In this example, the coffee filter acted as a sieve, to separate the solid particles and allow the liquid to flow through.
Tomorrow we will finish recording our observations, and discussing which strategy was more successful in separating a solution.
