Step 3: Try It OutNarrator: Now that the kids have started working, the noise level has increased dramatically. Aren't you glad you established a signal before they began?
As the kids work, move about the room and visit each group. Ask questions to help guide their explorations. For example, to help kids make predictions, ask "What do you think would happen if...?" Or, if a group seems stuck, ask, "Can you think of another way to look at this?"
And remember to encourage kids to change one variable at a time. This allows them to pinpoint what's working and what's not.
Let's watch the ZOOM cast as they start experimenting.
VIDEO CLIP
Mike: Adhesion is the ability of molecules to stick together.
Kortney: Yeah. So...
Mike: So...How could we get the water to stick to this? (Description: He gestures to the string.)
Kortney: Well, since molecules want to stick together, maybe we should soak it and then try what we were thinking of before.
(Description: Mike dips the string into the full cup of water.)
Narrator: Did you notice how Mike discussed adhesion and then asked Kortney how they could use this idea to solve the challenge?
Introducing the science concepts behind an activity is a great way to get kids thinking about possible solutions.
Another approach is making connections to things kids already know. When you're planning an activity, try to find a real-world connection that helps clarify the science concept.
Here's an example from the ZOOM cast.
VIDEO CLIP
Mike: You can see this in action next time you're taking a shower. Stick out your arm, and all the water that falls on your hand will go under your hand and drip down your arm. This is because the water is sticking to your arm and to the other water.
