“In every walk with nature one receives far more than he seeks” John Muir
Spirit days. We had another fantastic week, and we can’t believe we only have one more full week left of the school year. We had fun on Tuesday, twining with our bffs on Look Alike Day. We loved choosing a new name on Wednesday. We laughed out loud with our classmates’ jokes on Thursday and shared our lunch with cicadas on Friday (lol.) Talking about cicadas, did you know that cicadas make a variety of sounds? Each cicada species creates a distinct sound to attract females of their own kind. We listened to some of the cicada sounds to compare them. Some resemble sprinklers, others sound like an ambulance, and others like an alarm. So cool! On Mystery Science, we watched how other insects make their sounds using different parts of their bodies, like crickets, who use their wings, or grasshoppers, who use their legs. We watched a zoomed-in image of these insects’ bodies and found ridges on the part of their bodies that they use to make their sounds. In the same way, cicadas use the ridges on their sides called tymbals. They move their tymbals so fast that they make a loud sound.
We have a chance to listen to their “songs” during recess and when we go to gym class. We like to stay quiet for a few seconds and enjoy the different sounds. Fun fact: Do you know what a group of cicadas is called? A Chorus!
Insects. This week, Ms. Anna’s class insects emerged, and we were just curious about what types of insects they were. We borrowed them for a day and tried really hard to see them up close using our magnifying glasses because of how tiny they are. We first noticed that they are insects because they have all the attributes of insects: six legs, head, thorax, and abdomen. We could see two eyes, but it was hard to tell if they were compound. They have antennae, but it is also hard to know if they have wings. Armed with that information, we looked at pictures of different insects and took our best guesses. Some students guessed they were crickets; others thought they were walking sticks. A couple of students thought they were grasshoppers, and most thought they were praying mantis. And they were! We learned a few facts about Praying mantis:
- They can be brown or green
- Their color helps them camouflage
- They can be one to six inches long
- They have five eyes, two compound, and three simple eyes (just like bees!)
- Some have wings
- They are carnivorous
- They can eat small insects
- They can also eat small animals like lizards, mice, and even hummingbirds! Yikes!
- They catch their prey as fast as a flash!
- They can live up to a year
- They can be found in every continent except Antarctica
We also learned about their life cycle. Contrary to the other insects we’ve studied, the praying mantis only has three stages: egg, nymphs, and adults. During their nymph stage, they can molt multiple times from their exoskeleton until they become adults. And just like cicadas, they leave their shells everywhere. Nature never ceases to be amazing!
Believe it or not, we keep finding different critters in our backyard. Every recess, we are excited to see what we will find. The “cicada carpet” has become a familiar sight on the playground. We are so used to finding them everywhere that we have noticed a significant shift in our students’ attitudes towards these insects. Those who were initially hesitant to touch them or even fearful are now happily collecting the dead cicadas or their exoskeletons. The highlight of our week was the diverse array of beetles and caterpillars we found. We found more green caterpillars and the most strange white-hairy one. It was so pretty that we wanted to keep it forever, but we talked about how important it is for them to keep them safe in their natural habitat. Is it possible to find more types of critters? We sure hope so. Stay tuned!
