This is another post that comes from the Science Photo of the Day. It worked well there, but has great potential for a full blown Experiment of the Week activity. To try this, you will need:
a plant or some seeds
a pot to grow the plant in
potting soil
a scale to weigh the plant, pot, and soil
We will explore how plants grow, by growing a potted plant. You can use a plant from your local garden shop, or you can plant seeds from your favorite plant.
This experiment is about bread. If you have used my website for long, you know that I like experiments with food, especially when it is tasty food. We regularly bake bread, and there are few smells that are better than the smell of freshly baked bread.
My Brazilian Salmon Pink Bird-eating Tarantula (Lasiodora parahybana)
My pet tarantula molted this week, which started me thinking about exoskeletons. While we have our skeletons on the inside, other creatures, such as spiders, insects, and crabs wear their skeletons on the outside of their bodies. What would it be like to have your skeleton on the outside instead of the inside?
This experiment comes from tonight's supper. I have been craving a big pot of Great Northern Beans; so last night I put some into a pot of water to soak overnight. The results reminded me of a fun science experiment I had done before.
This time, we will conduct an experiment to measure cellular respiration of yeast when it is fed different sugars. While we tend to think of sucrose (table sugar) when we hear the word sugar, there are actually many different chemicals that fall into that category. As we will see, different sugars have different properties.
