Teachers and families across the country are facing a new reality of providing opportunities for students to do science through distance and home learning. The Daily Do is one of the ways NSTA is supporting teachers and families with this endeavor. Each weekday, NSTA will share a sensemaking task teachers and families can use to engage their students in authentic, relevant science learning. We encourage families to make time for family science learning (science is a social process!) and are dedicated to helping students and their families find balance between learning science and the day-to-day responsibilities they have to stay healthy and safe.

Sensemaking is actively trying to figure out how the world works (science) or how to design solutions to problems (engineering). Students do science and engineering through the science and engineering practices. Engaging in these practices necessitates that students be part of a learning community to be able to share ideas, evaluate competing ideas, give and receive critique, and reach consensus. Whether this community of learners is made up of classmates or family members, students and adults build and refine science and engineering knowledge together.
In today's Daily Do, What happened to our ice?, families participate in a Dinner Table Discussion (see below) about the phenomenon of melting ice. This sensemaking discussion has four parts:
This activity is called a Dinner Table Discussion (DTD). DTDs do not have to physically happen at the dinner table. Rather, they are intended to facilitate connections for the family around a discussion about science ideas wherever you may congregate for a meal. Whether you cook dinner at home or order takeout, the DTDs are centered around relevant science phenomena and raise common questions children have about the world around them. The goals of DTDs are to
Like Daily Do’s, these types of activities are considered “micro-learning experiences.” They are not intended to replace classroom science learning, and are not intended to be used as “homeschool” stand-alone science lessons. They are not intended to result in being able to generate robust, complete scientific explanations of phenomena. Conversely, they are intended to move student thinking along the continuum of learning.
These are intended to be family-style discussions, with provided parent talk-moves, that stimulate thinking among family members and move everyone along the continuum of learning. Each DTD has these components to them linked below. These components provide fertile ground for the discussion to be authentic, phenomena-driven, rooted in science, and focused on sensemaking.
If this is your first Dinner Table Discussion in the Daily Do series, NSTA recommends reading the guidance before trying your first family discussion.
Dinner Table Discussions have three main components. The following guidance will support you in facilitating your family discussion.
Introducing the Phenomena and Raising the Question
Our goal is to raise a puzzling question for students that does three things: (1) prompts them to think about what they currently know; (2) makes them ask what they want to know more about; and (3) helps them discover something new that moves them along the learning continuum.
Tell me what you know....
We want to foster having children explain what they think they understand to be true. These previous understandings are critical to exposing what they know and the questions they have. As they work to explain their current understandings, they will realize they don’t know as much as they think, which will spur them to generate further questions.
What questions do you have?
In developing insufficient explanations for things, students generate authentic questions they have that are the pathway to discovering the answer. In other words, these are our explanatory questions that if we were able to investigate, we would understand more about what we currently don’t understand. Our goal here is to generate lots of questions, but anticipate the common ones. The common questions are central to developing an explanatory idea, and we want to foster that environment by giving adult family members discussion prompts (talk moves) to facilitate the discussion for students as they work to articulate what they want to know more about.
Pursuing Common Questions
Our goal here is not to develop a robust and complete scientific understanding of a particular phenomenon. Our goal is to help students/children understand a puzzling phenomenon more deeply than they currently do. Learning is a continuum, and our goal with these discussions are to move students further along the continuum, not get them to the end. The objective is to stimulate thoughtful discussion that is rooted in a scientific phenomenon and a scientific explanation.
Have you ever taken a long sip of a day-old soft drink from your favorite fast food restaurant? Have you ever noticed the ice in the glass that was filled with ice and keeping your drink cold on a hot summer evening is not there anymore by the time dinner is ready? If you have, you know a little about asking the question "Where did my ice go?"
In today's Daily Do, we will figure out what happened to your ice!
There are two options for introducing this phenomenon:
Encourage your children to explain to you what they know (or think they know) about why ice melts. Ask them to “explain the science of why ice melts.” Children will attempt many varieties of explanations, but our goal here is not to distinguish between right versus wrong answers or ideas. Rather, we want to foster discussion about the “how” and the “why” of water changing from a solid (ice) to a liquid (water).
Accessing Prior Knowledge
Students may also draw on knowledge from previous grade levels during this part of the discussion.
All of these connections to ideas and learning opportunities at previous grade levels should be encouraged by asking follow-up questions such as these:
“Can you tell me more about that?”
“How do you know that?”
You can say something like this: “It sounds like we have more questions than answers. What questions do you have about how and why ice melts?” Encourage children to ask as many questions as possible that are relevant to the discussion.
Common questions could include these:
Where did the ice go?
What does ice turn into?
Is ice the same thing as water?
Where does the water on the outside of the glass come from?
Can you turn other liquids besides water into ice ?
Read the Scientific American article "What Makes Ice Melt Fastest?" (as a family or individually), and complete the extension activity, if you so choose. High school students can engage in this activity independently. Younger students will need more assistance. After reading the article and completing the activity, ask your children the following questions:
What is one new thing you learned that you didn’t know before?
Which of our original questions did we answer in our discussion and by reading the article?
What other questions do you have about phase change (how things turn from solid to liquid, liquid to gas, liquid to solid, etc.)?
Now that we understand more about how and why ice melts, it makes us wonder some other things about phase changes. If you and your children would like to pursue an extension activity connected to this Dinner Table Discussion, check out the Daily Do Why Does the Ice Melt Faster?
NSTA has created a What happened to our ice? collection of resources to support teachers and families using this task. If you're an NSTA member, you can add this collection to your library by clicking Add to My Library, located near the top of the page (at right in the blue box).
The NSTA Daily Do is an open educational resource (OER) and can be used by educators and families providing students distance and home science learning. Access the entire collection of NSTA Daily Dos.
