iExploreScience supports teachers embracing student-owned science -- science learning where students are self-motivated by their own sense of wonder to nourish their curiosity, drive their learning, and truly become scientists through the study of real-world phenomena.

vertical whiteboards aren’t just for math! I love to use them in my science classes, too!

Today, we started modeling a phenomenon and instead of working on our worksheet, I had students get up to the boards and work together to create a model. Then, the students observed all of the other models, and we discussed what we liked about the different iterations… how certain ways of creating the model helped us understand the phenomenon better (captions, labels, showing change over time, etc!). Lastly, students then created their own model on their paper…

It was awesome watching them ā€œstealā€ (in the best way!) others’ ideas, and representations as they worked on their own (preliminary) ā€œfinalā€ model… and I’d say the whole activity it was way more productive than simply having them go straight to modeling on their own!

if you’re looking for more ways to use whiteboards in science, there is a podcast episode I recorded over the summer that shares some of the ways I incorporate vertical whiteboards into my classroom

we’ve moved on to understanding that matter is made of particles that are too small for us to see — but that their behavior explains all the things we CAN SEE!

my students loved getting out of their seats to become PARTICLES OF MATTER! and experiencing it in their bodies definitely made the learning stick way better than any slides or notes! šŸ™ŒšŸ»

we collected evidence to determine if air really IS matter (you know, being invisible and all!) and talked just a little about fair investigations, trials, and data (more to come with that soon enough!)

we also practiced writing our first (short!) CER to communicate our thinking āœ…

one thing teaching math has taught me to incorporate more into science is ā€œsprinkling inā€ ideas and concepts and spiraling skills and content throughout the year!

we started our first science unit — particles of matter! Students are investigating what happened to Luluā€˜s latest batch of lemonade - which just wasn’t sweet enough! - by learning about the particle model of matter, what happens when solids dissolve, and how we can provide evidence that even when we can’t see it… matter never really disappears!

I’m really excited about this ā€œwhat we’re learningā€ for this year, and I’m trying to post some sort of art back from each day or nearly each day…

My plan is to incorporate on the same wall everything that we are doing in math, science, and social studies and any other fun things that come up… and ideally, if we can start making connections among the topics, that would be really, really awesome!

The only thing I’m not sure about is what to do when we run out of space… I don’t know if I’ll take down the material from prior units or maybe condense it? I don’t know. This is a new thing for me and I’m just excited to see how it evolves. šŸ¤·šŸ¼ā€ā™€ļø

Since we’ll be starting science in earnest in the next few days, stay tuned to see what science material appears!

week two begins!

Working on place value relationships in math, as we get ready to introduce decimals, and started our nature journals in our first science class!

We’ll start our first unit in science on Thursday!

finally got into some regular classes to end the week… and now looking forward to the 3-day weekend and getting back to it with math AND science next week!! 🤩

another ā€œfirst weekā€ day — still learning routines, getting to know each other, and setting up the systems that will make our classroom run smoothly and efficiently!

forgot to photo our discussion and brainstorming for ā€œwhat good group work looks likeā€ but tomorrow we’ll practice and use a rubric (based on today’s discussion) to reflect!
