Students investigate the property dependence between liquid and solid interfaces and determine observable differences in how liquids react to different solid surfaces. They compare copper pennies and plastic "coins" as the two test surfaces. Using an eye dropper to deliver various fluids onto the surfaces, students determine the volume and mass of a liquid that can sit on the surface. They use rulers, scales, equations of volume and area, and other methods of approximation and observation, to make their own graphical interpretations of trends. They apply what they learned to design two super-surfaces (from provided surface treatment materials) that are capable of holding the most liquid by volume and by mass. Cost of materials is a parameter in their design decisions.

What happens during metaphase?
In this video, I would like to talk about the stage of mitosis called metaphase.
Mitosis consists of four stages and I always remember mitosis using PMAT
For Prophase Metaphase Anaphase Telophase
During metaphase the sister chromatids align in the middle of the cell.

However for this to happen a couple of things need to happen during prophase
During prophase the chromatin condenses into x shaped chromosomes.
Each half of the x is a sister chromatid and identical copies of the DNA
The two sides of the x shaped chromosome are attached at the centromere.

During metaphase spindle fibers appear These fibers create something called the spindle apparatus.
It consists of spindle fibers, centrioles, and another fiber called aster fibers
In plants, the centrioles are missing.
These spindle apparatus move to the poles of the cell.
The spindle fibers attach to the centromeres of the sister chromatids at the kinetochore.
After the spindle fiber is attached at the kinetochore the sister chromatid is pulled along the spindle apparatus and eventually end up in the middle of the cell.

Metaphase is the shortest stage of mitosis but is important because it helps ensure that new cells have correct copies of the chromosomes.
Take a journey to the cell

Everybody is familiar with the feeling that things are not as they should be. That you are not successful enough, your relationships not satisfying enough. That you don’t have the things you crave.

In this video we want to talk about one of the strongest predictors of how happy people are, how easily they make friends and how good they are at dealing with hardship. An antidote against dissatisfaction so to speak: Gratitude.

Generative AI tools are here to stay. There’s a debate around whether or not they should be embraced in spaces of learning. Recent reports suggest that the risks of using these tools might outweigh the benefits, threatening cognitive development by doing the thinking for their users. This is forcing educators into a dilemma: how do they make the most of AI’s potential, while also protecting students’ ability to think for themselves? In this episode, host Samantha Laine Perfas talks with cognitive scientist Tina Grotzer, applied mathematics professor Michael Brenner, and educator Ying Xu about how to use AI tools to enhance learning, rather than replace it.

Math is part of the STEAM system - Science, Technology, Engineering, Art, and Mathematics! It is essential to teach all five of them. And the best way to engage with children is to turn lessons into a game. Leave a comment down below which part of STEAM your children are the most excited about!

⭕️ Math can be a hands-on activity! When we make it more tactile, it makes it easier for kids to learn. Filling up rubber gloves with rice, we make a new set of hands that the kids can count on. This is a great way to introduce addition and counting because the answer is visual. It’s also great for subtraction!

⭕️ Pin it Down. This addition game is a great start to doing sums in the head. All the answers are right there- you just have to do the work to find the right one! It’s really satisfying when you pin the equation to the right answer.

⭕️ Math Garage. I love this addition game because it shows how many different answers there can be to the same question. This is great for kids that are active and love to solve puzzles, or just love cars!

⭕️ Is it time to pick apples yet? This addition activity shows a whole math formula altogether. The apples on our math tree also help count, so you can double-check the answer you came up with. This one is also great for getting fast sums.

⭕️ The Addition Machine. Do you like my addition machine? I find because you can write your own numbers, this one is the most versatile of the bunch.

Google's NotebookLM just received major upgrades, including a move to the Gemini 3 engine, a new Data Tables output format, and an expanded custom prompt field that now supports up to 10,000 characters. These updates transform NotebookLM from a basic document chat tool into a serious research and knowledge management platform. In this video, we break down exactly what changed, why it matters, and a smarter way to use NotebookLM that most people are missing entirely.

Google also launched AntiGravity in November 2025 — a free, agent-first AI development platform that lets anyone build apps, dashboards, and tools using plain English instructions. When you connect AntiGravity to NotebookLM via an MCP skill, you get a complete research-to-build pipeline where NotebookLM handles the knowledge layer and AntiGravity handles execution. This video covers 5 practical workflows people are already using with this combination, including building competitive research tools, automating content pipelines, creating client knowledge bases, running automated deep research, and turning notebooks into interactive apps.

Whether you're building a service business, looking to automate time-consuming work, or exploring ways to use AI tools to create more value for clients, this workflow is worth understanding now before it becomes mainstream. Both NotebookLM and AntiGravity are currently free to use, making this one of the most accessible AI setups available in 2026. Everything covered in this video is based on real, documented features — no exaggerated claims, no fluff.

Pre-order our book YOU ARE AN ARTIST (which includes new assignments!) here: http://bit.ly/2kplj2h

The Art Assignment visits artist collective Dignicraft during their residency at the McColl Center for Art + Innovation, in Charlotte, North Carolina. Omar Foglio, José Luis Figueroa, and Paola Rodriguez give us the assignment to facilitate an Encounter / Encuentro, a form of community building.

Sarah Green then explores social practice with the work of Nicolas Bourriaud, who suggests that the rise of urbanization after World War II gave raise to art that is also urbanized.

INSTRUCTIONS - Encounters / Encuentros
1. Think of two people who you know who have similar interests but don't know each other
2. Facilitate a collaboration by introducing them and suggesting they do something together
3. Document the experience
4. Upload to your social media platform of choice using #theartassignment
5. Fame and glory (your work might be featured in a future episode)

Sometimes in life, it is acceptable to add or subtract numbers that have been rounded up or down to make calculations easier. In these videos, the Kids Academy teacher explains rounding numbers to the nearest ten and rounding numbers to the nearest hundred.

A real-life example of when rounding numbers is used could be:
A student needs new clothes. Her parents take her shopping and tell her that she can spend $75 on any items she likes. She immediately sees a shirt that costs $19.98. She finds a pair of pants for $27.99 and some shoes for $14.95. Does she have enough money to buy all three items?

Rounding makes the calculations easier. When the numbers are rounded to the nearest 10, they become $20.00, $28.00 and $15.00. Now the numbers are much easier to add and she determines she has enough to buy them all.

The video explains the rounding numbers rules are simple. When you are rounding numbers to the nearest ten, you look to the number to the right in the ones place. If that number is five or higher, you will round up. If the number is four or lower, then you round down. Likewise, if you are rounding numbers to the nearest 100, then look to the number on the right in the tens place. If that number is five or higher, you will round up. If the number is four or lower, then you round down.
The video teacher recommends underlining the number that you are rounding and drawing an arrow to the number to the right that determines whether you round up or down. The video provides several examples of rounding numbers as well as scenarios that require rounding numbers in real-life.

Rounding numbers 3rd grade, is a skill that prepares students to use math in their everyday lives. Teachers find these videos are a great tool that can be used for teaching re-teaching or for enrichment.
