I wonder, after seeing my post’s title, how many people are singing The Clash’s popular tune. I sure am. 😀
The reason for today’s post is for me to see how many people are utilizing the information on the site — if I should keep this site up.
If this site is used by folks, it’ll stay. If it’s not, well, I think it’s time to go.
So…
No stay comments = this site will be gone in November.

Whoa! The long thick fibers you pull out of the extraction mixture are real strands of strawberry DNA. As you may know, DNA is present in every cell of all plants and animals and determines all genetic traits of the individual organism.
While other fruits are soft and just as easy to pulverize, strawberries are the perfect choice for a DNA extraction lab for two very good reasons: (1) they yield way more DNA than other fruits, and (2) they are octoploid, meaning that they have eight copies of each type of DNA chromosome. (Human cells are generally diploid, meaning two sets of chromosomes.) These special circumstances make strawberry DNA both easy to extract and to see.
To extract the DNA, each component of the extraction mixture plays a part. Soap helps to dissolve cell membranes. Salt is added to release the DNA strands by breaking up protein chains that hold nucleic acids together. Finally, DNA is not soluble in isopropyl alcohol, especially when the alcohol is ice cold.

Supplies you will need:
Directions:
1. Start off by using Elmer’s glue to glue on your craft sticks, 7 of them, to your cardstock or cardboard.
It really doesn’t matter what you use for the backing just as long as it is strong enough to support the sticks. Also, make sure that you cut your backing so that it’s no longer or wider than the popsicle sticks. Let dry!
2. This is the step the parent will want to help with. Hot glue a few strands of the raffia onto one craft stick for the scarecrow’s hair.
I just cut a few pieces for each side. Once the hot glue is dry you can then glue the stick onto the rest of the scarecrow body.
3. We choose to paint the scarecrow at this point. If you think it would be easier for your kids to paint prior to attaching the hairpiece then you can do that beforehand. We just found it easier to paint afterward.
Now that everything is painted you get to sit and watch paint dry. Luckily it’s just craft paint and it will be dry in minutes, not hours.
4. The next step is to paint on the adorable face. Depending on the age and painting skill level of your children you could always paint the face on for them or cut out pieces of felt or foam and attach with glue.
We didn’t add anything to the hat but you could also add a flower and turn this into a scarecrow girl. Just dress it up, however, you like it.
5. Attach magnets to the back of your scarecrow. We used two .75 inch adhesive magnets to hold ours up. That’s it, you are all done with your popsicle stick scarecrow.
Simple ingredients. Simple directions. BIG results. TRY IT OUT!!
As you might recall, this past Monday, I shared a salt art project. The original idea was to create a colorful spider web.
My daughter decided to make a web and a witch’s hat. Since the original post had an image of a finished web, I’m not sharing hers. Instead, check out her vibrant witch’s hat!

GLUE AND SALT SPIDERWEB CRAFT
To make this fun spiderweb craft, you will need construction paper or tag board. We used black paper because it provides a nice “pop” from the paint colors. But any color, or even white paper, will work. You’ll also need a pencil to draw with, Elmer’s glue, table salt, watercolor paints, and a soft brush.
Start by drawing a dot with a pencil for the center of the spider web. Draw lines freehand or with a ruler that intersect the center point and go from one edge of the paper to the other. It is better to err on the side of fewer lines rather than too many as the glue will make the lines thicker.
Use your pencil to draw curved lines between each “ray” of the spiderweb. Again, encourage kids to make these line farther apart than they might if they weren’t being traced with glue.
Trace each long ray of the spider web with glue then move on to the curved lines that connect the rays. The lines will be the smoothest if the lid of the glue bottle doesn’t touch the paper. You could even do a practice run in which kids get to make a drizzled free form design before they move onto their spiderweb.
While the glue it still wet give each child a ramekin of table salt. Use two fingers to pinch the salt and sprinkle it on top of the wet glue. Cover the glue with salt completely and gently slide off the extra.
The spiderweb will need to dry before moving onto the next step. Dry time is usually overnight but depends on humidity levels as well as the thickness of the glue lines.
When your spiderweb is dry it’s time to add some color. Using a soft brush, plenty of water, and watercolor paints add a drop or two of color to a salt line. Drop and dab the paint. No scrubbing or the salt and glue will melt away, dissolving your spider web. A light touch is crucial!
Watch the color spread down the line of glue and salt. Even on dark paper the color is vibrant and has a “pop.” Encourage kids to use different colors next to one another and watch as they overlap and blend together.
