 Changing Properties: compounds & mixtures

(i.e. Chex mix is a mixture, but this slime is a compound)

For those of you who requested the recipe, it is at the end of this post.

 In the above activity, Eloise was able to observe the alcohol separating the compound found in a Sharpie marker. Notice the two lines of pigment traveling up the strip of coffee filter in the left cup. The right cup contains only water. There was no observable change.

Below: Eloise had to build models of atoms using gumdrops.

After they were constructed, she was then able to use them to form models of Chemical Equations.

Stay tuned for more pics as we work our way through the second half of this school year.

SLIME/FLARP RECIPE


1 bottle white glue
1 tsp. Borax (powder in box by laundry soap)
food coloring (any color)
2 Large plastic Party Cups
3 wooden craft sticks (like ones in pic. above)
measuring cups & spoons
tap water

1.)measure 1/4c glue & pour into 1 of the cups.

2.)measure 1/4c water and pour in w/glue.

3.)mix w/wooden stick very well until smooth. If you wish to color your slime add a few drops of food coloring at this point and stir.

4.)In a second plastic cup measure 1c. water.

5.)add 1 tsp. borax to c. with water. Stir with new craft stick till Borax is dissolved.

6.)carefully pour the Borax solution into the glue solution stir with last clean craft stick.

note:initially the slime will be very stringy. Pick it up and squeeze/knead till some of the liquid drains out. Dump extra liquid. Repeat as needed. Store in a zip-lock bag.
