Learning to Teach Science
One evening, I trudged up the hill to my classroom. It was after a long day of teaching, and I had spent a hot hour commuting to the university for my teaching credential lessons. The evening’s session was on learning to teach science. It is one of my favorite classes, but I did not envy our professor who had to infuse engagement and learning in a bunch wannabe-teachers after we had sent the whole day and week teaching. She is an excellent educator and never shies away from the task though. Somehow, she ends up making us feel invigorated and inspired to teach science by the time we leave, and that is noteworthy in and of itself.
Really, I am glad some people chose to develop others as teachers, and are so generous with their time and talents.
Moody and Muggy – like Venus?
This class, she chose to have a guest educator come in, and the lesson they had planned will stay with me for a long time. She had us answer a question related to our solar system as we walked in. She asked us which planet’s moods matched our own. Hot and muggy like Venus, or dealing with too many moons like Saturn.
- Mercury: swift orbit – cratered surface
- Venus: scorching heat – thick clouds
- Earth: liquid water – teeming life
- Mars: red dust – massive volcanoes
- Jupiter: big red spot – swirling storms
- Saturn: beautiful rings – gas giant
- Uranus: tilted axis – ice giant
- Neptune: supersonic winds – deep blue
It was an interesting exercise and she soon solicited a few responses. Some felt they could be like Uranus or Neptune just to freeze or pause for a moment, or maybe just to escape the heat of the past week.
A giant step is ?
Soon afterwards, she led us outside to the sprawling campus grounds overlooking the bay. The sun was beginning to dip in the sky, and she said a little walk might do us all a little good. We agreed and off we went. She set up a traffic cone in one spot and called it the sun. Then, she had us estimate the number of steps we would have to take if the scale was : one giant step ~~ 10 million kilometers.
We guessed and took the steps placing the cones as we went. We only went up to Saturn, but it was enough to get us out of our heads, and into an expansive space. A place to let go of our daily worries and revel in the grand universe we belong to.
A simple search gives us this, but walking outside and acting silly with our classmates as we took giant steps never teaches us things the way a textbook or video does.
If 1 step = 10 million km, here is the step-by-step distance from the Sun out through the solar system (rounded to the nearest whole step):
Sun to Mercury: 6 steps (~58 million km)
Mercury to Venus: 5 steps (~50 million km)
Venus to Earth: 4 steps (~41 million km)
Earth to Mars: 8 steps (~78 million km)
Mars to Jupiter: 55 steps (~550 million km)
Jupiter to Saturn: 65 steps (~646 million km)
Saturn to Uranus: 143 steps (~1.43 billion km)
Uranus to Neptune: 165 steps (~1.65 billion km)
Neptune to Pluto: 140 steps (~1.40 billion km)
The more I live and experience life, the more I realize how little I know.
As we headed back inside, my head was already buzzing with a dozen different activities I could do with the children with this simple activity. They would never forget scales, and the enormous universe we live in once we had tried this. Everything can be wondrous.
Where is the time?
The only problem is the classic one faced by all teachers. Where was the time? There is precious little of it given all the curriculum demands, testing requirements, standards to be met, small-group coaching, differentiated learning for different skill groups etc. Dedicated teachers try their best, and learning all that goes into running a smooth classroom, is something I am enormously grateful for.
Excerpt from Billy Collins poem:
Early People – By Billy Collins Book: Whale Day & Other Poems
“Teaching is a noble and time-honored profession,
But little is known about it
Because no one is allowed in the classroom
Except the teacher and the students”
As we babbled our way out after the class, we were an invigorated bunch full of ideas to try out with the children, and I saw our Professor’s smile turn wider and fill her face, as we thanked her.
My mood, as I walked back to the car after a long day, matched Earth – teeming with life and ideas.
I wish I could give my own students lessons like these over time- lessons they will enjoy and remember. Even if they do not remember the specifics, it is enough if they remember feeling awe, accomplishment, sighing with understanding, and being happy to be learning.
