Science fun!

Yesterday my sister and I did Snaptricity circuits for science. We tested our light circuits by going into the basement to see how bright it got. We also powered a fan and made it fly up into the air. Circuits can help move electricity. For a circuit to work, it has to be a shape that connects sides or the electricity won't go through.

On Monday we learned about Canada lynx. In the winter they are whitish gray and when it gets warmer they turn more brown. They change colors so they can blend in with their habitat. Their coats are also thicker in the winter to keep them warmer. Canada lynx don't hibernate, like some animals. 

One animal that hibernates is a groundhog. When it's hibernating it only breathes once every six minutes! Some animals don't get enough oxygen in the winter, like fish. Sometimes the water freezes and there isn't enough oxygen in the water. Then the fish die, and this is called winter kill. Then in the spring the dead fish get washed up onto the shore. That happens at the park near us. Then it smells funny, like dead fish.
