17.  You should repeat the experiment to make sure your results are accurate.  By redoing (re=again) the experiment, you can find out if your interesting data was caused by mistakes you made, the way you did the experiment, or small differences in the things you were investigating.

18.  Marco’s model is like a seal because seals have a layer of fat that insulates them, or keeps them warm, called blubber.  Seals swim in very cold water like Marco used in his experiment.  His model is different because seal’s blubber is much thicker than the layer of shortening (Crisco) that Marco used in his model.

19.  The plant will most likely not grow well near Gina’s house because the environment in the mountains is too different from the environment near the beach.  For example, the soil and temperatures in the mountain region are different than the environment near the beach.  The mountain plant does not have the adaptations for growing near the beach.

20.  Possible answer example:  Skunks spray a smelly liquid when they are scared.  This adaptation helps keep predators, or animals that want to eat the skunk, away since the predators do not want to get sprayed.
