Interview With Science Teacher “Jill Jensen”

Do you know scientists use lynx scat to trace their inhabitants dimension? Or that there are two completely different shapes of snowflakes on planet Mars? Or {that a} very particular species of frog turns clear when it sleeps? Typically you simply must ask a science instructor to seek out out extra.

Jill Jensen is the president of the Minnesota Science Instructor’s Affiliation, and a seventh grade life science instructor at Scott Highlands Center Faculty in Apple Valley, Minn. She joined host Cathy Wurzer to speak concerning the newest information in science.

We try and make transcripts for Minnesota Now obtainable the following enterprise day after a broadcast. When prepared they’ll seem right here.

Audio transcript

INTERVIEWER: Clearly, there’s plenty of snow on the bottom proper now. And that is received a few of us speaking concerning the information about some new findings about snow on Mars. For this and different science information, we have invited science instructor Jill Jensen to hitch us. She teaches seventh grade science at Scott Highlands Center Faculty in Apple Valley and is the president of the Minnesota Science Academics Affiliation.

Properly, Jill welcome.

JILL JENSEN: Hello, thanks for having me.

INTERVIEWER: About this snow. We all know it snows on Mars. And scientists realized some new issues, although, about that snow. So inform us about that.

JILL JENSEN: Yeah, so Mars really has two sorts of snow. They’ve water ice, which is what we’ve right here on Earth. However the Mars environment, as a result of it is so chilly and due to what the Mars environment is made up of, they really get carbon dioxide snow as nicely. And the attention-grabbing factor about carbon dioxide snow is due to the molecular construction of carbon dioxide, it really kinds cubes as a substitute of the six-sided snowflakes that we’re used to.

INTERVIEWER: OK, so cubes. All proper, that may be attention-grabbing.

JILL JENSEN: Think about nearly like a subject of like salt grains, or one thing.

INTERVIEWER: OK, so let’s transfer on to a different story slightly nearer to house. Minnesota has lynx, however their numbers are falling. However there’s some excellent news.

JILL JENSEN: There’s. So scientists have been monitoring lynx. Lynx are actually arduous to seek out. They’re solitary creatures. They do not are inclined to assault wildlife or people. So they simply are inclined to maintain by themselves. Their numbers have been considered fairly low.

However among the best methods to truly monitor them is by amassing their scat. And thru their scat assortment, scientists have been doing this for over 20 years now and sending it to a DNA database in Montana. They usually’ve been in a position to get a number of info to assist estimate the inhabitants.

They’ll inform what households of lynx are round and what number of are surviving. They usually’re actually hoping to make use of this info to make a restoration plan for them. So lynx have been on the threatened species listing for about 22 years now

INTERVIEWER: OK, and type of like– that is like monitoring human wastewater throughout COVID? I imply, yow will discover rather a lot by waste.

JILL JENSEN: Yeah, proper. So there’s really fairly a bit of knowledge they’ll inform. They’re really in a position to inform what number of they’ve, what number of kittens they’ve, what number of are surviving, what number of completely different particular species there are. And it really has been in a position to give them a greater concept of what their inhabitants is. And sure, as you mentioned, wastewater from people additionally provides us a number of clues as to what is going on on with COVID as nicely. So a number of info type of hiding in our waste.

INTERVIEWER: Let’s hear about some extra animal information. This can be a enjoyable story about frogs within the rainforest.

JILL JENSEN: Yeah, there is a kind of frog referred to as a glass frog which lives within the tropical rainforests of Central and South America. They’re only some centimeters large. They usually’re principally energetic at evening. They usually’re referred to as glass frogs as a result of the pores and skin on their stomach is clear. So if you happen to have been sitting beneath it and regarded up, you’d be capable of see all of its organs.

So a method that it has developed to assist itself mix in is by hiding all of its blood whereas it is sleeping into its liver. And in order that makes it actually clear and actually be capable of disguise from predators. And that is attention-grabbing to scientists as a result of they’ll do that with out damaging their peripheral organs or tissues. They usually do not appear to endure from any blood clots. So if we may determine the magic of the blood work of that tumbler frog for people, we may have some good well being information for folks affected by some blood problems.

INTERVIEWER: Attention-grabbing. Say by the way in which, earlier than you go, what are you educating within the classroom?

JILL JENSEN: We’re in the course of our chemistry unit. So we’re periodic desk, and atoms and atom constructions, after which how they mix to make molecules and compounds. However the story about Mars has been notably attention-grabbing as a result of we really simply completed watching The Martian and are pondering rather a lot about what life could be like on Mars and if we would wish to go and discover there sometime.

INTERVIEWER: All proper. I recognize you becoming a member of us, Jill. Thanks a lot.

JILL JENSEN: Yeah, thanks. Glad to be right here.

INTERVIEWER: Jill Jensen is a seventh grade science instructor at Scott Highlands Center Faculty in Apple Valley. She’s the president of the Minnesota Science Academics Affiliation. To learn extra about any of those science tales that we talked about, we’ve hyperlinks on our web site mprnews.org.
