Heart & Blood
What does our heart look like?  Our heart pumps blood throughout our body, but how and why?

How to Cut Out a Heart Shape

  1. Fold a piece of paper in half.
  2. Put the folded side going up and down.
  3. Starting at the fold, draw slightly more than half a circle going up and away from the fold.
  4. From the end of that half-circle, draw a diagonal line down to the fold. The further away from where you started the slimmer the heart will be.
  5. With the paper still folded, cut along your line, going through both halves of the paper.
  6. Unfold the heart!

Valentine’s Day experiment? Just add your favorite Valentine shapes to this acid/base experiment and you will end up with the most amazing scientific Valentines you’ve ever seen!

Start making Valentine’s crystals now
They should be ready by the 14th.
Twist the pipe cleaners into the shape of a heart, with a “stem” left to hook over pencil on top of a STRAIGHT SIDED container. (I learned this the hard way, you can tell. You can’t get the crystal out of any non-straight container!) Experiment on seeing what you can add to the solution to make the crystals red. (food coloring, cherry or beet juice – what else?)

Optics of red.
As the eye sees red – tire your eyes of seeing red.
Stare intently at a red sheet of paper for 30 seconds of longer. Then switch to staring at a white or black sheet. What do you notice? On a color wheel, what color is exactly opposite of red? Compare to the color you saw on the second sheet. Why do you think this happens?

Shine a light through a prism, creating a rainbow. Where in the rainbow does red appear? Top? Bottom? Between which other colors?

What is Love? – A Scientific Perspective

Why is it important to talk about love?
Does everyone mean the same thing when they use the word love? Is loving your mom the same as loving chocolate or your country?
