Science: Pure Substances & Mixtures Check Your Understanding


1.


2.
Aluminum foil, table salt, and distilled water are all examples of pure substances.

4.
Pure substances contain only 1 particle type whereas mixtures have 2 or more different particles.


1c.
Cookies are a mixture of different ingredients (eggs, flour, sugar…)

taste of oranges, after they have lost all this during storage.

Seedfolks corrections to chp.8 (revise/edit)
Sae Young is a Korean immigrant and dry clean owner.

Listening to her, we can see that she is a gentle soul and kind lady.  

She wants to be maternal (to love and care for a child) but was unsuccessful with pregnancy.

She has experienced 2 negative events: the sudden death of her young husband (leaving her lonely)
and a robbery/assault at her business (leaving her emotionally scarred)

As a result, she was traumatized and lived in seclusion, anxious and fearful; it took her a long time
to leave her apartment and face the world again.

The garden helped her build her self-confidence and trust others again; by offering water funnels
to the gardeners and seeing others use them, Sae Young began to feel happy and connected
once again to her community.

Theme/lesson: we need to live in relationship with others to feel a sense of belonging and to feel
valued; these relationships need to be positive and encouraging to feed our soul.
