🧪 And, to easily add science into your lesson plans, we’ll also send you the link to our shop where you can download the record sheets that goes along with this experiment and 29 other jaw-dropping science experiments so kids can easily keep track of their results! 👋 👉 Comment below or DM us “Sticky Ice” and our STEM Bot will immediately send you the link to our website where you can learn all about the science behind the experiment! The ice will have magically attached to it! I *guarantee* you already have everything you need.ġ-Mix food coloring with water and pour into ice trays before freezingĢ-Grab a small bowl, fill it with the colorful ice cubes and waterģ-Place the string on top of an ice cube and sprinkle salt over it.Ĥ-Wait 1 minute and then carefully lift up both ends of the string. #reeses #kidsscience #scienceeducation #scienceforkids #simplescience #kindergartenteacher #preschoolteacher #firstgradeteacher #scienceexperiment #STEMkids 👉 Comment below or DM us “Magic Pumpkin” and our STEM Bot will immediately send you the link to learn more on my blog!Īnd follow for more simple science experiments kids beg to repeat! Save so you can quickly pull up the play-by-play when it’s go-time. And because the candy coating is colored, we can watch it all happen before our own eyes! That’s the same kind of change that happens in this science experiment! The sugar coating on the candy melts in the warm water changing it from a solid to a liquid. Then, when that liquid gets hot enough, it can evaporate into water vapor and become a gas. For instance, ice can melt into water and become liquid.
Pour enough hot tap water in the center of the plate to cover the bottom.Īn object’s state of matter can change. This science experiment is hands-down the COOLEST pumpkin in the patch!Īrrange them on a white plate to make a pumpkin outline.

More Irresistible Kids’ ScienceĬontinue the excitement with 30 of our favorite, kid-approved science experiments PLUS a no-prep journal for scientists to record their results! Post navigation Capillaries are tiny hollow tubes within plants, like the trees that the toothpicks are made from.Ĭapillary action, the ability of a liquid to flow in narrow spaces against gravity, occurs in plants because water is attracted to the sides of the tiny straw-like capillaries (xylem).Īs the water molecules move into the xylem, they pull additional water molecules with them because water molecules are “sticky.” This process is called cohesion and occurs because water molecules are polar, they have a slight positive charge on one side and a negative charge on the other. To get more specific, the water is absorbed into the wood fibers due to capillary action. When we added the droplets of water to this bent part, the exposed dry wood fibers absorbed some of the water and became swollen.Īs the wood swelled, it causes the toothpick to straighten itself.Īs it straightened, the pointy ends of the toothpicks pushed against each other causing the star to open. We placed all the bent parts of the toothpick together in the center of the star formation. When we bent the toothpicks in half, we stretched some parts of the wood fibers while compressing other parts inside the toothpick. The toothpicks we used were made of dried wood. “The water pushed the toothpicks apart when you dropped it in,” she explained. My 6 year-old was pretty confident she knew the secret behind the magic. We repeated the kids’ science demo several more times since each of my kiddos just had to have a turn adding the magical water droplets. Both my kids’ jaws dropped and my littlest just had to climb up on the table for a closer look. It only took a few seconds for the magic to happen and the star to open. Now we were ready for some kids’ science magic! Using a dropper, I slowly added a few drops of water to the center of the star and waited. Once I had 5 bent toothpicks, I arranged them on the plate with the middles (the bent parts) of each touching to form a closed star shape. It took me a few toothpicks before I got the hang of bending them in half without completely breaking them. To make the star, I took 5 toothpicks,(one of each color) and carefully bent them in half until they snapped but didn’t break apart.
Toothpicks (we used colored ones but plain would work, too).
