Real Science 4 Kids Chemistry

This year I decided to try the Real Science 4 Kids curriculum. There are not a lot of secular science curriculums aimed at homeschoolers, and I had heard good reviews on this one. My sons are now in grades 6 and 7 so I figured the Middle School, grades 5-8, version would be perfect for us.  We decided to start with Chemistry.
 I am lucky that our charter school purchases our curriculum and educational supplies, so I don't have to worry as much about cost. I decided to go ahead and also order the hands on kit (which has supplies for all three topics: Chemistry, Biology, and Physics). We got the Level 1 kit from Home Science Tools

Level 1 Kit for Real Science 4 Kids

We just finished with the Chemistry unit and so far it this curriculum working for us. The text is very simple, but goes into good detail at the same time. The hands on experiment with every chapter is great. The textbook, laboratory workbook, and teacher's manual are all nicely laid out and easy to follow.

Here's a little summary of our experience.

Chapter 1: Matter

This chapter introduces atoms and the periodic table. I supplemented here with Teacher Book Bag's Periodic Table of Elements Card Kit.  Printed, laminated, and cut out the kids could handle all of the elements of the periodic table, sort them into types, match symbols with names, and even re-create the periodic table on the pocket chart (at least a good chunk of it before running out of room!)

Another supplement were the free downloads from Sunflower Schoolhouse 

There is a big selection of interactive on-line periodic tables for the kids to explore as well:

Chapter 2: Molecules

This chapter was lots of fun because we got to make molecules out of marshmallows!

Start with some carbon, oxygen, and nitrogen.

Even little sister joined in the fun!

Chapter 3: Chemical Reactions

Who doesn't love a good chemical reaction experiment? Several different chemical reactions are discussed: combination reaction, decomposition reaction, displacement reaction, exchange reaction, and spontaneous.

Chapter 4: Acids, Bases, and pH

The experiment for this chapter was to make an acid-base indicator. The kids really had fun with this one, cutting up and boiling the cabbage and making the pH paper.

 Chapter 5: Acid-Base Neutralization

In this experiment we got to use our cabbage water again to plot an acid-base titration. It was exciting to watch the solution turn from an acid into a base.

Chapter 6: Mixtures

We learned about two types of mixtures: heterogeneous and homogeneous. In the experiment we got to see first hand how soap helps dissolve oil in water.

Chapter 7: Separating Mixtures

This was one of my favorite experiments; using paper chromatography to separate individual colors in various inks.

Chapter 8: Energy Molecules

The kids read about a lot of the same things I recently learned in a college level nutrition class about nutrients, carbohydrates, monosaccharides, disaccharides, polysaccharides, starch, cellulose, amylose and amylopectin.

For the experiment we used tincture of iodine (in the kit we purchased) to test a variety of foods for starch content.

I created vocabulary flash cards for Chapters 8, 9, & 10. I printed them on card stock (they are already formatted to print on business cards, Avery 5371, if you don't want to have to cut them up yourself). I would put the words in the kids' workboxes with the definitions in the pocket chart and they would go match the words with the definition (or the other way around). Together we would check the pocket chart to see if they got them correct. Click here to link to a free pdf file of the vocabulary cards: Chemistry Vocabulary

Chapter 9: Polymers

After reading about polymers the experiment was to observe a change in properties as two polymers are added together. The kids were very excited to discover the fun, gooey glue that you get when you mix together white glue and laundry starch!

Little sister had lots of fun playing with the goo after the experiment was over!

Chapter 10: Biological Polymers: Proteins and DNA

The final chapter is on DNA and in addition to the experiment in the text, we are going to extend the unit for a couple of weeks with some supplemental hands-on kits:

Have you used Real Science 4 Kids? What did you think of the curriculum?
