When animal populations become crowded, many animals have the ability to get up and move elsewhere. Students think about factors in simple and complex ecosystems that contribute to that balance and consider possible factors that contribute to imbalance.
Students investigate insect life cycles with fruit flies, cockroaches, etc.
Students construct a toy in groups of two, using Lego's. Students will understand that turning one handle can cause a distant object connected to it to move. The Senses We rely highly on our vision yet receive messages from our auditory and olfactory senses and interpret them emotionally more often than intellectually. These two activities help students to become more aware of senses that humans tend not to use as much as other animals.
