## Preschool Science: Color-Mixing, Day 2

To reinforce the color-mixing ideas we'd talked about previously, we tried another experiment with food-coloring and water.  This demonstration relies on the tendency of liquids to reach equilibrium.  When we connect the jars, the water will flow until it has reached an equal level in all of the jars.  If we put food coloring in … Continue reading Preschool Science: Color-Mixing, Day 2

## Preschool Science: Color Mixing Day 1

We have been talking about boiling, melting, freezing, and states of matter with our preschooler, so we tried this simple color-mixing activity. First, we made blue, red, and yellow ice cubes.  We needed five of each color for this activity, and we made them simply by putting one drop of food coloring in each section … Continue reading Preschool Science: Color Mixing Day 1

## Chalk It Up

More handwriting practice today!  My three-year-old has really been into the Reading 1A trial course from the Ron Paul Curriculum.  He has only watched the first three videos, but he's watched each of them several times over the past five days and is asking for them, as well as Math 1A.  He is still not … Continue reading Chalk It Up

## Tessellation Tip

In order to keep them from crawling up the walls in their last week before summer vacation, I've given my seventh graders a tessellation project.  There are about ten million youtube videos explaining how to do this, so I won't bore you with the basics.  Instead, I'll just tell you about my struggles and how … Continue reading Tessellation Tip

## Area of Mixed Polygons

In 7th grade math, we're working on area.  We've gone through all of the basic formulas with careful attention to how they are related to one another -- the triangle being half of a rectangle, the trapezoid being a combination of two triangles, and so forth. Now we're on to area of mixed polygons, such … Continue reading Area of Mixed Polygons

## Pythagorean Theorem Follow-Up

Activity for the big kids today: Without using a ruler, determine whether this triangle is equilateral, isosceles, or scalene. Prove it.
