Day 45 – Sick Day and a Science Project

My poor Sera was very sick with a stomach virus last night. We were both up at 4am. FOUR AM. So many of my friends have little babies, and I know they are up ALL of the hours…but I am definitely not used to 4am. The benefit of having older children? I set her up on the couch with blankets and a bowl, put on Lord of the Rings, and went back to bed.

Anyhoo, she was still watching when I woke back up at a more reasonable time. We read from the book of Exodus together, read another chapter of Silent Spring, and watched another episode of Liberty’s Kids.

I had to get some work done, so when Josh came home after work he did a science project with Amelie. The project was supposed to show the way that carbon dioxide turns water into sparkling water. We thought this one would be great because recently we have been experimenting with fermentation: kombucha, yogurt, kefir water, ginger beer, and hard apple cider. The girls have helped make all of these things at home, and this lesson was supposed to reinforce the science behind all of it.

However, we had a little bit of human error and things didn’t turn out perfectly as planned. That’s okay, it’s all a learning experience! Amelie was so cute through all of it.

My favorite part? “WHAT’S A THIRD!?” The girls have a knack for asking questions like this in front of homeschool skeptics, strangers, and of course, the camera. I also love how Sera arises from her sick bed long enough to hold the funnel and then just walks away. Enjoy:

Carbon Dioxide Water Project

Carbon Dioxide Experiment

Materials:

  • Balloon
  • Plastic straw
  • 2 empty water bottles with lids
  • Vinegar
  • Baking soda
  • Water

Instructions:

  1. Fill a plastic water bottle 1/4 full with vinegar.
  2. Fill a second plastic water bottle 1/3 full with water.
  3. Carefully pour 2-3 tsp of baking soda into the balloon
  4. Pull the balloon tightly over the open bottle containing vinegar. Be careful not to let the baking soda fall into the bottle yet–let it hang to the side of the bottle in the balloon.
  5. Lift up on the balloon so that all of the baking soda falls into the bottle at once. This will react with the vinegar and produce carbon dioxide. The balloon should inflate. Shake the bottle help the process.
  6. Carefully pinch the balloon opening and remove it from the bottle so that no gas escapes the balloon.
  7. Using a straw, release the gas from the balloon over the top of the water in the second bottle.
  8. Remove the balloon and the straw and quickly place a lid on the bottle.
  9. Shake vigorously. Carbon dioxide should force bubbles to form.
