The Lion Sleeps Tonight – part 2

Yesterday was my twenty-fourth first day of school, well, not completely. I was with teachers and administrators for meetings and new school year information, but kids will arrive Thursday. I am excited and I am sure the kids are, too..

I have one more day of meeting and a FULL day to work in my classroom and prepare for Thursday’s real first day of school with kids.

After school, I asked a colleague to film the solution to the riddle I posed in last week’s Tuesday’s Tune – The Lion Sleeps Tonight.

In the jungle, the mighty jungle
The lion sleeps tonight
In the jungle the quiet jungle
The lion sleeps tonight

Before the solution reveal, let’s review the rules.

  1. The raft needs at least one animal to paddle it across the river, and it can hold at most two animals.
  2. If the lions EVER outnumber the wildebeest on either side of the river (including the animals on the boat if it is on that side), the lions will eat the wildebeest.
  3. The animals cannot just swim across – there are crocodiles in the river, there are no tricks, the animals must use the raft as described in rule #1.

Did you give it a try?

If so, how long did you persist in the challenge?

And now the solution…… Continue reading The Lion Sleeps Tonight – part 2

last day of summer break

It’s Sunday and I am sitting at my summer office and listening to the gentle whirrrrr of the hummingbird at the feeder to my upper left. It’s Sunday morning quiet and except for the occasional car, truck, or airplane I can hear the birds singing in the trees. Fern and Ivy laying nearby enjoying the time outside.

Friday evening, I noticed it seemed darker than normal at 8:15 PM. Early Saturday morning, I read the morning New York Times email which confirmed Friday evening’s observation, summer is waning.

Confirmation of my observation piqued my curiosity so, I researched. As it turned out, Wednesday August 9th was also the final 8 PM sunset for this summer where I live. The next 8 PM sunset won’t occur for another 274 days or until May 9th. Being curious, I researched further, here are some lasts and nexts, in case you are wondering:

  • the last 7 PM sunset 9/15/2022, the next 7PM sunset, 3/17/2023
  • the last 6 PM sunset 10/22/2022, the next 6PM sunset, 3/12/2023
    change in daylight savings time occurs 3/11/2023
  • the last 5 PM sunset 11/5/2022 at 5:41 PM but the shift away from daylight savings time makes the sunset on 11/6/2022 – 4:40 PM, the next 5PM sunset, 1/27/2023
  • the earliest sunset occurs at 4:21 PM between 12/3 to 12/14/2022

If you are curious, you can research your location using the Time and Date sun calculator. There is a plethora of information: sunrise, sunset, sun angle, and more.

I am an early riser. At the height of summer, the sun rises early, and it is light before 6 AM. The sunrise has been later each day, too. Summer is waning. Continue reading last day of summer break

learning

Yesterday, I went for a hike at my favorite hiking spot, Herrick Lake Forest Preserve. It’s a short drive from house and it makes a huge difference in my hike compared to my neighborhood. I’ve posted photos from previous hikes at the forest preserve. The preserve has woods, a prairie, and a marsh and the main crushed limestone hiking trail winds through it all.

the access road I take to get to the trail

It was a beautiful day and I had initially planned to hike first in the morning, but I decided to hike later in the day. I knew it would be relaxing and restorative.

When I had arrived home from the lake Monday afternoon, I discovered a house with no internet. I tried to resolve the issue, but a solution was beyond my capabilities. I called for support and learned the earliest a service technician appointment was available, was Thursday morning with an 8-12 service window.

The main reason I had come home from the lake was that I had enrolled in a graduate level class to learn more about assessing students in my science classes. Assessment or grades have been a HOT TOPIC in public education over the past couple of years and I wanted to learn more. The class was virtual with two internet ZOOM meetings.

I could use my phone as an internet hot spot, but the prospect of ZOOMING using my phone concerned so I decided to use the local public library for my heavy internet usage. It worked out well and I was patient and waited for the service tech to arrive Thursday morning.

When the tech arrived, I was outside working at my ‘summer office’ on the deck using my phone as my internet connection. I invited him, but he told me he wanted to start outside the house where the line enters the house. That’s where he found the problem, somewhere down the line there was a broken connection. A couple of years ago we had an outage and it caused by mice chewing on the wires in the junction box in the backyard. We talked about it, and he told me that it was a common problem and he laughed saying animals gave him job security.

He told me that he couldn’t make the repair, but another service tech was needed to find the break and make the repair. He told me I didn’t need to be home for the repair, so I used the opportunity to take off and hike. Continue reading learning

W^2 – wonder

How in the world did the balloon get inside that flask? Wonder. Scullen Middle School, Naperville, IL May 24, 2022 10:45 AM

This week for my W^2 post, wonder.

I snapped this photo yesterday in class after four straight demos of the scientific principle,

As temperature increases, the volume of gas increases. As temperature decreases, the volume of gas decreases.

And while my students watched the demonstration, some understood, but some are still wondering what happened and how that balloon got inside the glass. Is it magic? No, it’s science.

It is Wednesday, the middle of the week and there are as I sit and type FIVE more days of school this year and then it is summer. I can’t wait, they can’t wait. But we are going to make those five days count.

I know it is going to be going to be a great day. I know it and I can feel it, so I’d better jump up, jump in, and seize the day. Making the Days Count, one day at a time, making the most of every day and trying to compress learning just like air particles can be compressed.

What makes you wonder these days?

Be Curious, not Judgmental

It is the Saturday morning before Easter and I am up early, before anyone else. Normally, I’d be at Loaves and Fishes volunteering helping families in need of food get the food they need, but Loaves and Fishes is closed for the holiday. I did work Thursday after school as it was the last day that families could get food this week and it was terribly busy.

Yesterday I was reading my devotional, The One Year Uncommon Life Daily Challenge by Tony Dungy. I was reading the entry for July 21st. I know yesterday was April 15th, but I started reading the journal a couple of years ago and I started almost two years ago on April 25, 2020, by starting with the January 1st entry. The intent was to read each day and finish a year later on April 24, 2021, with the December 31st entry, but that didn’t happen. Things happen and life gets in the way of good intentions. But each time I have read an entry; I have felt as though the passage is speaking directly to me. Yesterday’s title was “Discernment instead of Judgement.” As I read the entry, I reflected on its meaning, and I immediately thought of the TV comedy series Ted Lasso. Last week, a colleague and I had been talking about teaching science and the topic of Ted Lasso wisdom had come up. He mentioned a Ted Lasso quote, “Be Curious, not judgmental,” and we chuckled because I encourage my students to be curious and full of wonder in science. Continue reading Be Curious, not Judgmental

W^2 – snow moon

looking west into the setting snow moon – Wheaton, IL. Wednesday, February 16, 2022 5:09 AM

This week for my W^2 post, I have a snow moon. Every moon has a name and February’s is snow. The moon this morning was 98.2% of the full moon phase with the true full phase occurring later this morning at 10:56 AM. By that time the sun will make observing the moon impossible or the clouds will obscure it, regardless it won’t be visible to the naked eye so, I am thankful to have seen the moon each of the past two mornings when I let the dogs out at 5 AM.

We have snow in the forecast for tomorrow, and I believe my students will be a little excited with the prospect of a snow day on Thursday along with the effects of the ‘snow moon.’ So today’s will likely be an interesting day of learning.

We are still learning about light and every day there is a new reveal, that’s life as it should be. Something marvelous and full of wonder each day, like present.

Today is gonna be an awesome day, I know it and I can feel it, so I’d better jump up, jump in, and seize the day. And also, press publish. Making the Days Count, one day at a time, looking for wonder and sometimes finding it.

What has filled you with a sense of wonder recently?

W^2 – waxing moon

Venus and a waxing moon, DuPage Forest Preserve Headquarters, Wheaton, IL November 7, 2021, 5:26 PM

We’ve been watching the skies in my science classes this past week. We have been watching Jupiter, Saturn, and Venus in the early evening sky. It has been fun to watch the planets as well as my students when I begin class by asking,

“Did anyone go outside last night?”

Their eyes light up and some even produce photographs of the night sky they took on their phones. It’s exciting to see the wonder and enthusiasm for discovering something new. I found the video below and I was excited to learn about a partial lunar eclipse on the evening of November 18-19. You can check it out below. I will set my alarm to see partial lunar and I hope that it is a clear night. Watching and listening to my students makes me realize I am doing what I am supposed to be doing as I begin my seventh decade today. Yes, it is my birthday, and I am 60. I still feel like a young man full of curiosity and wonder. Making the Days Count, one day at a time, thinking like a young person keeps me young and full of excitement about what’s coming next.

Fern and her shadow on our evening walk, Wheaton, IL October 12, 2021, 6:35 PM

The days are getting shorter, and the sun sets earlier each evening as a reminder that we are headed into winter. Then the process will reverse again as it always does. Until that time, fern and I will have to start earlier in the afternoon. We’ll continue to Make the Days Count, one day at a time, one step, or sniff, at time, starting earlier each day.

When do you make time walk?

three things for an early fall afternoon

It’s been a while since I’ve sat down to write or even craft a Wordless Wednesday post. I’ve thought about it, but also thought about all the other things that are on my plate and in line on front of writing and posting. I even had a photograph selected for the 9/15 – W^2 post, but skipped it to accomplish something more important and more urgent.

the tree and the sun line up

I’ve been overwhelmed with school and life and just haven’t made time to simply reply to the comments readers have left for me. So, this morning I made time to go back to reply and be thankful. Honestly, I am thankful that many people read what I write here at MtDC. I know that when I look at my priorities when school is in session MtDC is falls into the important, but not urgent category.

 It’s late August and it’s hot, humid, and storms blow up in the afternoon. This magnificent thunder cell wrought heavy rains over a small area for over an hour, then dissipated and moved out over Lake Michigan and parts east. I fell asleep to flashes of lightning and rolls of thunder in the distance, but very little rain fell on my lawn. It’s Thursday, not Wednesday and I am going to make Thursday an amazing day. Making the Days Count, one day at a time, day 6 follows day 5, always.

How are your late August afternoons?
