Science Experiments

November 2, 2023 / ballarinc / 0 Comments

Today, we did 2 experiments. The first one was cooking an egg to demonstrate both a physical and chemical changes.

(We forgot to take pictures of this)

We also conducted an Oobleck experiment. We used the Scientific Methods to conduct the experiment. We learned that Oobleck is a Non-Newtonian Fluid – it looks like liquid but feels like solid!

Question: What happens when you mix cornstarch with water?

Hypothesis: I think that when I mix the supplies, the mixture will become ______________.

Supplies:

1/2 cup of cornstarch

1 cup of water

Test the Hypothesis following this process:

Step 1: Add water to a cup.

Step 2: Add food colouring.

Step 3: Add cornstarch.

Step 4: Mix everything up. Mixture should be able to be picked up like a solid but still flow like a liquid. This is a Non-Newtonian fluid.

Step 5: Record observation.

Conclusion: We learned that slime is a non-Newtonian fluid which is neither a liquid or solid depending on the forces acting upon it and does not have a constant viscosity.

Big Idea: Materials can be changed through physical and chemical processes.

First Peoples Principles of Learning: Learning takes patience and time.

Curriculum Competencies:

Observe objects and events in familiar contexts

Ask questions about familiar objects and events
Make simple predictions about familiar objects and events
Make and record observations
Sort and classify data and information using drawings, pictographs and provided tables
Compare observations with predictions through discussion

Content:

chemical ways of changing materials

Core Competency: Critical Thinking and Reflective Thinking

I can ask questions and consider options. I can use my observations, experience, and imagination to draw conclusions and make judgments.

Making Slime To Show Chemical Change

October 19, 2023 / ballarinc / 0 Comments

In Science, we conducted our first slime experiment. We used the Scientific Methods to conduct the experiment. On Monday, we made slime to demonstrate chemical changes. We tried first using cold water and second using hot water. The slime turned out better using hot water!

Question: Will this slime be sticky or stretchy? Will we be able to separate the ingredients once mixed?

Hypothesis: When we mix the ingredients this will create slime and will show chemical changes, our slime will now be solid.

Big Idea: Materials can be changed through physical and chemical processes.

We Are Learning About Physical and Chemical Changes

We started our science unit on physical and chemical changes. Yesterday, we learned about what Matter was and that matter has 3 states; Liquid, solid, and gas.
