Boxing Day Science

Adelaide received a science kit from her aunt and uncle for Christmas, which sparked a renewed interest in conducting experiments. First, she set up her lab in her room and did several experiments, some from the book in the kit and some with materials we had set aside for her earlier.
Next we set up for a two-part experiment designed to teach about the effect of additional carbon dioxide in the atmosphere. We read about greenhouse gasses, where they come from and what they do to the ozone layer and earth's temperature.
Adelaide logged the temperature in our mini ecosystem under the "sun."
Next, we were ready to make our CO2.
We took the CO2 we created and used a straw to put it into the container. It is heavier than air, so it sank to the bottom where it proceeded to heat up the temperature in the container over the course of several minutes.


Adelaide played with some of the variables to see what else might happen to the temperature.
