Country – De

June 5, 2017

It’s been a long time since we have posted on the blog.  Here is the scoop:

A few weeks ago we discovered that one of our frogs had hind legs!  We were so excited because we read in our research books that once they get their hind legs then it wouldn’t take long for it to become a frog.  Can you see the hind leg?IMG_3891

2 weeks ago we saw the same tadpole with hind legs had a growth on its side.  We brainstormed and tried to figure out what was happening with the tadpole.  We thought that Mrs. DeDonato fed the tadpoles too much food.  Others thought it may be where one of the front legs was going to grow.  As we watched this one tadpole it kept floating on one side. We took it out and put it in a smaller tank just in case it was sick and we didn’t want the other tadpoles to get sick.  In the  mean time we e-mailed Emilie, the biologist, and she informed us that some tadpoles get air bubbles and that was what it looked like.  Room 2 also talked about how if he/she was in the vernal pool it probably wouldn’t survive because it would not be able to hide from the predators.  Sadly the tadpole passed away the next day.  IMG_3950

The long weekend came and on the morning of Tuesday, May 30th, Mrs. DeDonato discovered that most of our tadpoles had passed away over the weekend.   Again, we had a discussion on what was going on.  Why did they die?  what can we do better?  We noticed that the water was pretty dirty (it was vernal pool water) and it had a strange smell.  One friend suggested we go back to the vernal and collect some things from the vernal pool like, moss, logs and more water.  Sadly due to the weather we cannot go back anytime soon.  So here is what we did, we borrowed vernal pool water from Room 1 and put in a smaller tank.  We transferred the tadpoles that were still alive to the small tank while Mrs. DeDonato cleaned and filtered the big tank.   Today, June 5th, we transferred the tadpoles from the small tank to the clean water.  We hope that these tadpoles survive!

Also, today Dr. Erikson came in an weighed our tadpoles with a special scale.  We have been talking about measurement so it was a perfect opportunity to see how much our tadpoles weigh.  We took out some tadpoles, one weighed .4 grams, another .5grams and we discovered that they weigh as much as a small paperclip.

Today we looked at one tadpole through our Ladibug projector.  We were able to focus on one tadpole and try and get screen shots of it so we could see it’s details.  What did your kindergartner see?  what colors?

We also video taped the tadpole and tried to determine if it primarily uses it’s tail to swim or it’s head.  what do you think?  Tadpole swim- slow motion  I have put the video up on my Instagram account  (@mrs.dedonato) so you can see it.

Here is another video of our tadpole-what do you see?  what colors do you see? tadpole in tank

It has been a crazy start to our frog unit.  Here we are a few weeks late but never the less we have been observing and gathering information about our tadpoles.  We had Emilie, a biologist, come and show us Wood Frog eggs and salamanders.  These animals are found in our own backyard, the vernal pool.  This is where Emilie collected our temporary class pets.  Our mission for this unit is to be conservationists.  We will do everything we can to make sure these tadpoles become frogs and then release them back to the vernal pool.  We decided that we would take vernal pool water and feed them fish food (Emilie provided this food and we discovered that it does not smell great).  We feed the tadpoles twice a day!  In the past two weeks we have seen our tadpoles grow!  Each day they get a little bigger.  As of 5/8 we can see their eyes and the different colors on the tadpoles.  Last week, we thought they were just black ovals with tails.  It is so exciting to see the small changes!  Below are the pictures when Emilie came to our classroom to show us eggs and tadpoles (4/25/2017).  Because of the rain we could not go and meet her at the vernal pool.

***************Below are the frog blogs from previous years.  You and your child are more than welcome to explore to see how and when our frogs developed.  It’s fascinating to see how the weather determines their life cycle. ***************

 

 

April 11, 2016—Day 9

We discovered that over the weekend our tadpoles got a little bigger.   Thanks to Room 1 we added a few more tadpoles to our tank.  Here are some up close pictures of our tadpoles.  We will be adding water, moss and sticks from the vernal pool this week.  Will that change how our tadpoles grow?

 

April 5, 2016—–Day 4

Today we discovered a fourth tadpole that hatched over night!  We were so happy that we had to do an observation!

April 4, 2016—Day 3

We have some eggs that have hatched!  We counted 3 tadpoles so far, we wonder if there will be more tomorrow.

April 1,2016—Day 2

No Tadpoles yet! But Room 2 is keeping an eye on them.  A lot of friends wonder if they would hatch over the weekend.  We will see Monday!  We also did great observations of our frog eggs in our science notebooks.

 

March 31, 2016- Day 1 

Frog eggs are here!  

Today Mrs. Erickson came to our class and brought us our Wood Frog eggs.  We will keep these eggs in our classroom until they become frogs.  We wonder how long it will take!

We were also able to touch the eggs, which we described as wet, slimy and squishy.

Mrs. Erickson gave us two jobs; 1) to be teachers to a 4th grade class!  They will come over and we will teach them all about a frog’s life cycle.  2) to find out which will hatch first; Room 2 eggs or vernal pool eggs.  We are so excited to find out the results!

Vernal Pool Walk

Room 2 walked to the vernal pool. We met Emily, a local biologist, and she taught us all about the vernal pool. Due to the warm weather, Emily said that all the animals that are dependent of the vernal pool are coming back already, which includes Wood Frogs. Emily will be collecting some eggs for us to take back into our classroom, and we will watch them turn into frogs.

June 10—Day 30

Today we took our final walk to the vernal pool.  Since our tadpoles were rapidly changing into frogs it was time to take them back home.  Tuesday morning Mrs. Erickson took our frog back to the vernal pool.  Today we discovered another froglet and we were absolutely sure it was time to take them back home.  We have enjoyed our time with our tadpoles and we did incredible observations.   As we were saying goodbye we wished them luck and hoped that they would all survive.

June 8, 2015—-Day 28

This afternoon, thanks to Mrs. Van  Sickle’s keen eyes, we discovered we have a frog!  We immediately scooped out the frog and put it in a smaller tank with less water, rocks and some moss.  Mrs. Erickson will come by in the morning and take it back to the vernal pool.

We wondered when it turned into a frog.  We also wondered what it eats, and Mrs. Erickson said that frogs at this stage eat bugs.

June 4, 2015— Day 26

Today Mrs. Erickson came to weigh our frogs.

What we learned:

  • We learned that as they loose their tails, they are getting smaller.  That is why our tadpole with 4 legs is a lot smaller than the tadpoles with 2 legs.
  •  We learned that we only want to weigh the tadpoles not the water or cup.

What we wondered:

  • How big is an adult wood frog.
  • How long will it take for them to be fully grown

June 3, 2015 — Day 25

We have a frog with front legs!!

May 29, 2015—Day 22

Today we had our second grade buddies come and learn about Wood Frogs.  We invited them because we wanted to teach them all we have learned so far.  The second grade buddies had questions like; how many tadpoles do we have?  Do they have names?  We told them we don’t know how many we have because they like to hide but we think we might have about 15-20.  We can’t really tell them apart so our tadpoles do not have names.

We showed them our science journals, and went through our Wood Frog observations.  We also had a chance to take them to the tank to observe and search for the tadpole with legs.  After we read through our science journals we showed them our frog blog!

May 28, 2015— Day 21

This afternoon room 4 and room 1 decided to observe each others tadpoles.  We split up and half the class went to Mrs. Wyman’s class while the other half stayed to welcome half of room 1.  We were here to answer any questions they had.  After 10 minutes we switched so everyone had a chance to observe.  There was a lot of wondering going on between the two classrooms.  Room 1 asked us why we had “stuff” in our tank.  We told them that we had gone to the vernal pool and collected part of the tadpoles natural environment in hopes that it would help them grow faster.   We told room 1 that the moss and stick were great places for the tadpoles to hide and rest. After our visit Room 1 was inspired by us and they decided to put a rock in their tank.

May 26, 2015—Day 19

One of our tadpoles has legs.  We wonder when the others will grow legs.

IMG_6152 IMG_6153

May 19, 2015—Day 15

After our vernal pool walk we brought back a log and some moss.  On Friday we put them in the tank and crossed our fingers that the tadpoles would love it.

When Room 4 came in on Tuesday they discovered that the tadpoles LOVED their new home and saw some remarkable changes.  The tadpoles eyes had more color, their tails were  longer and we think we can see the beginnings of some legs!

May 15, 2015  Day 14——Vernal Pool Visit

On this visit we noticed that everything was green!   There was a lot of mud at the vernal pool and we talked about how the water is evaporating.  We wondered if in a couple of weeks the water would completely evaporate.  Maybe there will be one more visit to the vernal pool before school ends.

We did not bring back rocks but we did collect a stick with moss and a clump of moss for the tank.

May 14, 2015    Day 13

What a wonderful day for science!   Today during our science time we noticed more changes happening with our tadpoles.  We noticed that there was something pink growing inside them.  We were wondering if they were lungs.  We also  noticed that our tadpoles are more active, they don’t sit at the bottom of the tank anymore.

After discussing lungs and why we need lungs we were wondering if our tadpoles looked different than the other classes.  We discussed that we have been giving our tadpoles the food Emily gave us and we have changed the water once but will keep changing the water every 3 weeks.  Are the other classes doing the same?  Room 3 and 2 are giving their tadpoles store bought food and not changing the water.  Room 1 is giving their tadpoles ‘Emily’s food’ but changing the water twice a week.  Those facts brought up the question; are Room 1’s tadpoles bigger than ours?  We were going to investigate further into that theory.

Room 4 thought long and hard about what would affect our tadpoles.  Then we decided it was time to go back to the vernal pool.  We decided that we needed to add to their habitat, maybe that would get our tadpoles to become frogs faster.  Tomorrow we will go back and collect rocks and plants and see what would will happen to our tadpoles.  IMG_5985 IMG_5986 IMG_5989 IMG_5990 IMG_5987 IMG_5988 IMG_5991

We also wondered:

What would happen if we put the tadpoles outside in the tank?

If we put them outside, would birds come and eat them?

What would happen if we put the tadpoles in darkness for 2 weeks?

What would happen if we put more water in our tank?

May 12, 2015   Day 12

Today we looked at our tadpoles with our document camera.  We were able to see them up close and were amazed.  As we were observing we noticed that we could see right into their bodies.  We wondered how long it would take our tadpoles to grow hind legs.  We also wondered how long it would take for the lungs to grow, and if we were going to be able to see them.   We will keep a close eye on them!

May 4, 2015   Day 6

During the weekend our tadpoles went through some changes!  They got bigger, you can see their eyes and their tails are getting thinner and longer!

IMG_5828          IMG_5830_2IMG_5859 IMG_5853_2IMG_5854 IMG_5855 IMG_5856

May 1, 2015   Day 5

We saw that the tadpoles’ tails are mostly clear but a little white.  We saw that one of the tadpoles’ head looked like a fish head.  One of the tadpoles almost touched the top of the water!  Some of the tadpoles looked like a V.

Vernal Pool walk 

Today Room 4 went to the vernal pool behind Woodland School.  There we met Emily, a biologist.  She taught us about vernal pools, frogs and salamanders.  We were able to see, hear and touch frogs and salamanders!

  1. Hi Kindergarteners, I loved looking at your video of the tadpoles. What types of things did you notice in the video? Do you think that the adult frog will look anything like the tadpoles? Dr. Erickson
