Get started on the great physical change activities in my Physical Change Unit
with lots of blotter paper and water crystals.
You'll get twelve plain 3" x 6" pieces of blotter paper
- cut apart and you'll have 144 strips of blotter paper for students to use with their own watercolor felt pens.
I'll save you time by drawing lines on each end of 3 pieces of paper with the black ink, blue ink, brown ink, and red ink featured in my unit. That's 12 more pieces of blotter paper, cut apart to make 36 strips of paper for each color.
To assess student learning use the six pieces of blotter paper with dots created using six different combinations of colored inks. You'll have twelve strips of each different combination of colored inks.
After you cut the blotter paper into strips, just add cups with water, and watch as your students collect data and then apply what they've recorded in class to identify the dots on each assessment paper.
For the water crystal experiment, you'll get 2 tablespoons of water crystals
- enough for 24 experiments. Let the crystals dry out after use and you can use them again.
Just add containers of water, crayons, paper towels, printed paper flowers, a few drops of food coloring, and you're ready to go!
