Science Fair Time

It's science fair time.  My 6th grader decided that she wanted to see how baking powder affected muffins.  It was pretty interesting.  I liked this project because she could really do it on her own.  I helped by taking the pictures.

Batch 4 had 8 t of baking powder in it (double what the recipe called for).  They were dry and VERY brittle.

Batch 1 had NO baking powder.  Batch 2 had the normal amount.  Batch 3 had half of what the recipe called for.  And batch 4 had double the amount the recipe called for. 

We used a measuring scoop for each muffin cup.  So this shows that baking powder really does affect the consistency, density and even taste of the batter!
