3. Now remove about an inch of the plastic coating from both ends of the wire and attach the one wire to one end of a battery and the other wire to the other end of the battery. (It is best to tape the wires to the battery – be careful though, the wire could get very hot!) Now you can experiment by picking up paper clips and small non-aluminum objects.
These sound like big words for our little ones, but there’s an easier way to break it down. Water and oil won’t mix because they’re not the same “weight” or substance (just like clay and LEGOs won’t become one). Now add a drop of food coloring (which is heavier than oil) and a fizzy tablet and watch the air bubbles take coloring with them to the top. Head on over to S. L. Smith’s blog to see how it’s done.

Fire is fun. Colored fire is even better. These additives are safe. They won't, in general, produce a smoke that is any better or worse for you than normal wood smoke. Depending on what you add, the ashes will have a different elemental composition from a normal wood fire, but if you're burning trash or printed material, you have a similar end result. In my opinion, this is suitable for a home fire or campfire, plus most chemicals are found around the house (even of non-chemists).

If you’ve ever wondered how elephants keep their tusks clean, we’ve got the answer. They use elephant toothpaste! Find out how to mix your own and figure out the science behind this dynamic exothermic (heat releasing) reaction from Asia Citro at Fun at Home With Kids. Our favorite part? That you get to throw in some sensory playtime after the action’s over.

Geode Kits – For any child who thinks rocks are boring – a kit where they can break open their own geode is a great way to change their mind. National Geographic is a great choice if this is the type of kit you are looking for. Their products include hand-picked geodes and come with safety goggles and a stand for your child to proudly display their treasures. A great choice for children aged around 6 years old and above, they’re sure to be more interested in Earth science after this experiment.
Adults and kids will learn amazing new things about basic and acidic solutions with the Mind-Blowing Science Kit. Whether erupting an under-water volcano or growing colorful, jiggly crystals, this science kit mixes learning with experimentation in a fun and colorful way for a wide range of ages. Each of the hands-on activities in the science guide is intended to be performed by a young scientist under adult supervision, although these activities can be adjusted to accommodate a range of ages and capabilities while still maintaining the educational excitement of the original experiments.

What better way to teach your kids about science than with more than 70 experiments in a big bag? The Big Bag of Science contains scientific ingredients and a book of 30 pages filled with experiments like soda geysers, twisting tornadoes, growing jelly marbles, vanishing liquids, and more! The instructions are easy-to-follow and color-coded so your child will easily complete the experiment without any trouble. The book explains what’s going on in each experiment so they understand why and how things work.

It takes a few hours to see the results of this leaf experiment, but it couldn’t be easier to set up, and kids will love to see a leaf actually “breathing.” Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you’ll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.
Ah, slime. It’s the one thing that parents across the UK have been being pestered to make, so why not turn it into a science activity? For our concoction, we mixed shaving foam, PVA glue and a little bit of air freshener (fabric conditioner can work too!), to create a slime that you can swirl, stretch and crack, providing hours of fun. Try changing the quantities to see how the mixture changes, and ask the kids to explain the differences.

Like the popular baking soda and vinegar experiments, this film canister rocket literally takes it to the next level by using that creation of gas and energy to jet off into the sky. If your explorer has seen videos of mountain tops getting blown off during a volcanic eruption, this science project is pretty much any space lover’s version. Get the building instructions over at kids science activity blog The Science Kiddo.

I believe all children have the potential to be the next latest and greatest scientific inventor, but they just need to get things started. Holistic learning and hands-on approaches to teaching complex ideas make the difficult a lot less so. Absorbing information and fine-tuning their ability to sit and focus on one project will help set the foundation for them to become able to learn in a coherent and disciplined way, while also being fun.
Hi Jean, I too just love doing science experiments with the kids. I ran a science party for my son’s 6th birthday and I’ve also run science art workshops during the holidays. If you send me your email address I’m happy to email you my notes and experiments. Here’s the link to my post about the party last year : http://sunnysidearthouse.blogspot.com.au/2013/07/mad-science-party.html

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won’t be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton’s first law.

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)
