Ever got an electric shock off something? Demonstrate the science behind the shocks with this jumping frogs experiment. With just a balloon, some sugar paper and a woolly jumper, you’ll have frogs leaping in no time demonstrating the power of static electricity. It doesn’t have to be frogs either, let your imagination run wild to create some other jumping stars of this easy science experiment!
If you do this sidewalk constellation craft, you’ll be able to see the Big Dipper and Orion’s Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

Kids this age will probably enjoy a whole range of different science kits. It’s good to look for something which will help with what they are learning about at school. Pre-teens are becoming more and more independent, so it might be worth looking for an experiment kit which is simple enough for them to do alone, but still hard enough to keep them entertained and learning.
You won’t want to do this experiment near anything that’s difficult to clean (outside may be best), but kids will love seeing this “elephant toothpaste” crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The “toothpaste” is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).
Kids will love shooting pom poms out of these homemade popsicle stick catapults. After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they’re ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.
Biology is an important area of science because it teaches us about our bodies and the environment around us. With this Thames & Kosmos Biology Genetics and DNA Kit, your child will jump into the world of heredity and variation of organisms by using a test tube to isolate tomato DNA. This in-depth kit is fun and it covers so many areas of biology that most kits don’t cover.
Adults and kids will learn amazing new things about basic and acidic solutions with the Mind Blowing Science Kit. Whether erupting a color-changing volcano, creating a sunset in a test tube, 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. In addition to providing detailed instructions, the science guide makes it possible for those adults who might not have a background in science, or even any exposure to scientific experimentation, to knowledgably perform experiments successfully. The dynamic, colorful nature of the experiments included in this kit make it great for pleasing a crowd at family gatherings, parties, or science fairs. 

The products listed here may contain small parts that are choking hazards for children! Toys can pose a hazard to babies and young children – they can choke, suffocate, or otherwise harm the child. Young children explore their world by putting things in their mouths, but children under three years of age do not have a well-developed coughing reflex and will choke easily on small items. All children, regardless of age, need close supervision with any toys to help prevent accidents from happening. Adult supervision is required at all times!
Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won’t absorb the water.

This experiment is a great way for young kids to learn about static electricity, and it’s more fun and visual than just having them rub balloons against their heads. First you’ll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly’s wings. The wings will move towards the balloon due to static electricity, and it’ll look like the butterfly is flying.
Invisible inks either react with another chemical to become visible or else weaken the structure of the paper so the message appears if you hold it over a heat source. But we're not talking about fire here. The heat of a normal light bulb is all that's required to darken the lettering. This baking soda recipe is nice because if you don't want to use a light bulb to reveal the message, you can just swab the paper with grape juice instead. 

Kids ages 5-8 are at a crucial time in their understanding of science, math, and engineering. They're old enough to grasp how big ideas like the solar system and flight, things that perhaps once seemed magical, have scientific properties that allow us to explore outer space and build rocket ships. Kiwi Crate allows children in 1st, 2nd, and 3rd grade to begin a hands-on discovery of physics, chemistry, biology, and more, with fun projects that they can assemble themselves.

'Tis the season for gumdrops and this classic structural engineering challenge uses just two ingredients: toothpicks and candy. We’re particularly fond of this one from The Homeschool Scientist because it helps you explain what the concepts (engineering, load distribution, physics, shape comparison) are to your kiddos while they are building it. doing it. Visit The Homeschool Scientist to get going. And click here for five more gumdrop-themed challenges. 
Children aged 9+ start to want more detailed experiments and activities, which shows they are ready to begin real-science. Whether they have interests in physics, chemistry or robotics there is always something to get them started on their way. Some tops are harder than others and make sure you read all the features and facts so that you find the ideal gift for your child.
The kit includes components that can be used to breed bacteria and experiment with genetic engineering. If you know a child who’re itching to investigate the field of genetics, then this product might serve as a great gift. The Thames & Kosmos Biology Genetics and DNA kit takes children on a journey through reproduction biology, chromosomes and cell components.

Sir Isaac Newton discovered many integral concepts that are important for scientific discovery today, and this kit teaches them all: inertia, momentum, kinetic energy, and potential energy. This Engino Newton’s Law Kit is perfect for the kids who are very hands-on and like to build things. Your kids will understand how classical mechanics works by constructing their own catapult, balloon powered plane, drag racing car, crash car, and more.
This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud. This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you’ll be rewarded with a little cloud forming in the jar due to condensation.
Find out how plants “drink” water with some food coloring. Use carnations, roses, or stalks of celery submerged in the colored water and watch the liquid slowly seep through the plant’s “veins” and towards the leaves. Keep an eye out -- you could have a very colorful bouquet just after the first day. Get the rundown by Dad’s Book of Awesome Science Experiments over here.
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.
The good news is that your white lab coat doesn’t have to sit in the closet collecting dust. There are a lot of fun, simple, and hands-on science projects families can do together to learn and understand some of the basic principals of the natural world. And they’re not just for kids: even moms and dads will get a kick out of these 10 family-friendly science experiments!
Be careful: The water only has the power to make the sugar crystals “invisible” when it’s piping hot. After the water cools down and evaporates, the sugar turns back into a solid. And with a little help of your sugar-soaked string, the crystals will find a home to grow upon and become rock candy. Learn how to make your smart sweets with these instructions from the Exploratorium.
