►This site was originally created for my kids and their cousins, because we did science together. We eventually added more friends and I ended up having science classes for five years. I am no longer adding to the site (since 2014), but will leave it up for others' use. I do post to facebook occasionally if I come across something to share. =)

►Please accept my apology for any broken links or videos that do not work. I am always disappointed when people take down their videos from YouTube. It makes it hard to find just the right replacement. And because the videos were posted years ago, I usually have no recollection of what the video was about.
I kept thinking I would have time after my kids graduated, but life has filled up my free time with new responsibilities. =)

►Please do not email, asking me to post your website link, or to review something to put on my site. Any resources posted on this site are things I had found on my own during my regular searching for material I needed at the time, and liked it well enough to post here. There have never been any affiliates on my site, and as it is no longer active, would not be worthwhile at this point. ;)
Thank you!

Interactive Study Links
• Making flashcards at Quizlet.com is a great way to study!  Create an account to be able save your flashcard sets to practice every day.  You can make cards for whatever you need to study in the chapter, not just vocabulary.  Here are some examples, but be careful if you use these; some have had errors.  You will learn a lot more if you make your flashcards yourself.

(1) p. 1-6, Atoms and Molecules

Molecules in Solids and Liquids  (for younger kids, but still works!)
(Same as "Eureka!" Episodes 1617 combined.) 

Molecules are made of two or more atoms.

Eureka! Episode 22 - Atoms

Basically atoms and elements are the same thing. 
An atom is just the smallest amount of an element.
Read this ice cream analogy.

Eureka! Episode 23 - Electrons

Making Molecules with Atoms

►The Periodic Table of Elements with the names of the elements.
Some of the names of elements are copper, iron, and aluminum, carbon, oxygen, and helium, or potassium, calcium, and zinc.

Do you have any gold jewelry?  How can you know if it is pure gold or not?

Atoms and Molecules
Elements (atoms or molecules) and Compounds (a molecule)
Pure Substances and Mixtures
►Study this awesome diagram.  Hover your mouse over the parts of the image.

(2) p. 8-10a, Measurements and Units; The Metric System

(3) p. 10-12a, Manipulating Units

(4) p. 12-18a, Converting Between Units

Unit Multipliers at Donna Young.

Simple, easy!  A bit loud, so you may want to turn it down.

Look at Table 1.3 on p. 15 - Relationships between English and Metric Units.
And these symbols can mean approximately equal to≈, ≃, ≅.

More practice.  =)

(5)  p. 18-21, Concentration

It matters what air we breathe!
We normally breathe about 21% oxygen in the air we breathe.  The rest that is not oxygen, but other harmless gases, we simply breathe back out along with Carbon Dioxide.
Sometimes a patient needs more, like higher concentration of 80% oxygen.

People with Chronic Obstructive Pulmonary Disorder (COPD) cannot have high concentrations of oxygen.


  1. Hi! You have posted to watch the videos after the you read the page #'s listed. However, I am not seeing any page numbers listed with the videos. Can you please direct me to where this is listed? Thank you.

  2. Oh my! You are right.
    These posts are from last year, and I had started putting the page numbers along with the videos.
    Then I decided to write the message to view them after reading the textbook, and just copy/pasted that to all my previous Physical Science posts, not realizing that some did not have page numbers.
    Oh my! lol, I am just going to take out that message, because some prefer to watch the videos first. (This was a note to *my* students.) I will, however, put in the missing page numbers as soon as I have time. The books are currently in storage.
    My apologies. =D

  3. Thank you for sharing this content. What a wonderful site you have put together!

  4. You're welcome!
    I was surprised to find a comment on this particular post, as the "Eureka" videos had previously been removed from youtube.
    I see one is back now; hopefully they will put the rest back up. =)
