Fizzing Easter eggs. I’ve been dying Easter eggs with my kids since my son was one year old.

Fizzing Easter eggs

Dyeing eggs is always a fun experience, but making fizzing Easter eggs took it up to a whole new level. Not only did we get beautifully dyed Easter eggs, we combined art, fine motor development, and science into one fizzingly good activity! Have you ever tried combining baking soda and vinegar? We have! (See here and here and here and here and here.) When baking soda and vinegar combine, they create a chemical reaction that leads to fizzing and erupting. Fizzing Easter eggs simply combines this simple chemical reaction with the dyeing of Easter eggs. To dye your Easter eggs fizzing-style, you will need the following materials: Eggs, preferably hard boiledBaking sodaVinegarEgg dye (we used the PAAS dye tablets)Tray or plate to contain the mess To make our fizzing Easter eggs, I first prepared the dyes by mixing the dye tablets with vinegar.

Skittles Rainbow. Activity for ages 3 to 8.

Skittles Rainbow

In this kids’ science activity, we used candy from my daughter’s Halloween stash to create a beautiful rainbow in a jar. It was so easy and fun my 4 year old, A, didn’t mind sacrificing a little bit of her candy in the name of science. Getting Ready While A rooted through her trick-or-treat bag for some Skittles, I quickly grabbed a few additional supplies: 5 small glassesa glass of hot water (hot but not scalding)a tablespoonA pipet, or syringe When A returned with the Skittles, I had her begin by measuring out 2 tablespoons of hot water into each of the 5 glasses. Next, I opened the Skittles and explained that each glass would have different color Skittles in them, but not the same number of Skittles in each glass. 2 red4 orange6 yellow8 green10 purple A counted out the correct number for each color and placed them in the glasses of hot water.

The hot water helps dissolve the Skittles quickly. The Science Behind It. 50+ Genius STEM Activities for Kids - The Stem Laboratory. With a name like The STEM Laboratory, it’s no surprise that we’re obsessed about science, technology, engineering and math (STEM) activities for kids.

Blubber experiment: How animals stay warm

My husband, the kids, and I enjoyed a wonderful day viewing the exhibits and deepening our knowledge of the animals that live in the ocean. One of the exhibits was designed to give kids a sense of what blubber feels like. The exhibit had a white, rubbery substance that kids could press and push on. I used the exhibit to talk with my kids about the purpose of blubber and how it keeps animals warm.

Well, when we returned home I decided to go even further and let my kids experience for themselves how blubber keeps animals warm with a simple blubber experiment. Note: For more resources, printables and activities related to the ocean and its inhabitants, please see my ocean unit study page. I should start by saying that we had actually done this blubber experiment more than a year ago during our Arctic animals unit. I started by preparing two oceans containers of icy, cold water.

Science for kids - make a magnifying glass. Playing detective is one of my little ones favourite games, but to be a real detective involves lots of Science!

Science for kids - make a magnifying glass

So today we’re going to make a magnifying glass. Materials. Science Fun: 5 Everyday Science Experiments. Edible Bubble Science With Apples! Edible bubble science with apples...loads of fun, a great science lesson and experiment, and a delicious snack!

Edible Bubble Science With Apples!

Kids love bubbles! This science experiment feels more like playing games with your food, but the fact that it is all edible makes it even more exciting! You can use this activity as a chance to talk about bubbles, surface tension, water tension, surfactants, and more. Electric Eels. Instant Ice - Tips, Tricks, and Things to Watch Out For! Food Magic Tricks You Need To Try. Weekend fun: Make your own "Slushy Magic" at home! - Jill Cataldo. Here’s a fun and free idea if you have kids who like this sort of thing (or for yourself, if you just like slushies!)

Weekend fun: Make your own "Slushy Magic" at home! - Jill Cataldo

My children have become enamored with the Slushy Magic commercial currently airing. If you haven’t seen the commercial, Slushy Magic is a plastic tumbler with a lid and three “magic” ice cubes. Put the cubes in the tumbler, pour in your favorite drink, put the lid on and shake. Somewhere between one to five minutes later, the liquid turns into a delicious slushie! You can see how this would appeal to kids. To recreate the Slushy Magic effect, it’s important to understand how it works. So, here’s what you’ll need: Ziploc-type sandwich bagsTable salt and waterA cup with a lidA beverage with sugar in it (diet or sugar-free beverages won’t crystallize) The night before you want to make slushies, prepare the “ice cube” bags.

Roll the water bag up with the water at the bottom so that it freezes in a skinny shape that will fit inside the cup you chose. Make Your Own Slushies: Science for Kids. On a recent trip to Target, I picked up some Slushy Magic cups that were on 70% clearance.

Make Your Own Slushies: Science for Kids

The idea is that you freeze the ice cubes provided, add any liquid containing sugar, and put the cap on before giving the whole thing a good shake. They work fine and the kids love them. But it says right on the box that the ice cubes are made from just salt and water. It seemed so simple that I started wondering if you could make your own. I was also a little curious about how it worked. We used the tutorial at Jill Cataldo's Super-Couponing to make our own "magic" ice cubes. Marshmallow Launcher.
