These activities enhance hand-eye coordination and dexterity, which are essential for their growth. Developing these skills early on lays a strong foundation for more complex tasks as they get older.

These cool kindergarten science experiment ideas can be done indoors and outdoors and will assimilate fine motor and observational skills in kids. Try these out at home and outside, too.

1. Sink and Float

Sink and float is a fun science game where you take a sheet of paper and label two columns as sink and float, respectively. You then tell your child to collect a couple of household and simple outdoor objects and try placing them one at a time in a big bowl or pan of water to see whether they sink or float.

The science behind this is that heavy objects sink while light objects float. Your kids will love it.

2. Invisible Drawing 

Tell your kid to take a pan of water and mix in a few drops of dishwashing detergent. Get them a cotton swab and encourage them to draw or write their favorite letters on the bathroom window. After a hot bath or steam bath, they’ll notice that the letters or pictures they drew on the glass become visible despite the foggy surroundings.

The science behind this is that dishwashing detergent prevents water molecules from forming on the surface. Amazing!

3. The Egg Game

Give your kid a glass and ask him to pour water till the halfway mark. Now, ask your kid to mix six tablespoons of salt and stir. Again, instruct your kid to gently add water till it the glass is almost full. Tell him/her to place the egg in the water and watch what happens.

The egg will float because salt increases the density of the water.

4. The Magnet Game 

Ask your kid to gather a few items from around the house and place them near a magnet one by one. The ones that are made from metal or nickel will get pulled in while the others won’t stick to the magnet.

It’s a cool way to teach your kid about the magnetic properties of metals.

5. Color Theory Game

Take three glasses and fill them with water and add food coloring in each. Make sure the colors you add are red, yellow, and blue. Ask your kid to mix the colors and observe how new colors form.

The science behind this is that red, yellow, and blue, are primary colors which can be used to create more color variations.

6. Ice Cups

Ask your kid to take three cups of water and fill them up to the brim. Cover one of them with a lid and tell him to put them all in the freezer. In the morning, remind your kid to take them out from the freezer and check them again.

The cup with the lid will have noticeable cracks; the reason being water expands when frozen to cold temperatures, causing the cup to crack.

7. The Balloon Experiment 

Inflate a balloon and place it near your kid’s ear. Gently tap it and watch him/her marvel at the outcome.

The science lesson in this is that air molecules move and collide with each other, thus increasing sound waves.

8. The Wave Game 

Take a bottle and fill 3/4 of it with water and the rest with castor oil. Add food coloring to the mix and ask your kid to turn it upside down or side to side. Colorful waves will travel from one end to the other, thus teaching them that the Earth’s gravitational pull causes waves as it rotates around the sun.

9. The Gravity Game

Take a big watermelon and apple. Make sure you weight them each apart so that your kid realizes which one is heavier. Take them to a tall playground structure and ask him/her to drop both of them at the same time. If done correctly, both the objects will hit the ground at the same time. Your kid may be baffled at this experiment and ask how the heavier object didn’t reach the ground before the lighter one.

Repeat this experiment with bowling balls, ping pong balls, and other objects and watch your kids’ curiosity unfold! Newton would be proud.

The reason behind this is the Earth’s gravity attracts all objects with an equal pull and this pull’s force doesn’t change based on the weights of different objects.

10. The Water Lesson 

This little game involves three coffee cans, pieces of black construction paper, some tape, moist dirt, sand, and some time. Place the three cans in front of a sunny window on top of a radiation. Tape all the three with black construction paper except make sure that the second one is filled halfway with moist dirt and the third with sand. Ask your kid to make a hypothesis and check back after a while. Your kid will notice that the paper taped to the can filled with dirt will be drenched with moisture while the sandy can will have light traces of moisture, thus proving that soil retains water.

This lesson is also tied to their kindergarten curriculum and introduces them to their water cycle lessons too!

11. Bubble Inside a Bubble

Take a shallow dish and fill it with a mix of water and dish soap. Use a straw to blow a bubble on the surface. Now, dip the straw into the soapy water and gently blow another bubble inside the first one. Your child will see a bubble within a bubble!

The science behind this is surface tension—the soapy film allows the bubbles to form layers without popping immediately.

12. Dancing Raisins

Fill a glass with soda water and drop a few raisins into it. Watch as the raisins start to rise and fall, almost as if they’re dancing.

This happens because the carbonation in soda creates gas bubbles that stick to the raisins, making them float. When the bubbles pop, the raisins sink again.

13. Rainbow Milk

Pour some milk into a shallow dish and add drops of different food colors around the edges. Dip a cotton swab in dish soap and gently touch the surface of the milk. Your child will be amazed to see the colors swirl into a rainbow-like pattern!

The dish soap breaks the surface tension of the milk, causing the fat and water to mix and move, which in turn moves the colors.

14. Walking Water

Take three glasses and place them side by side. Fill the first and third glasses with water and add food coloring (red in one and blue in the other), leaving the middle one empty. Now, fold paper towels into strips and place them between each glass, touching the water.

Your child will see the water travel through the paper towels and mix colors in the empty glass, creating purple! This happens due to capillary action.

15. Static Electricity Butterfly

Cut a butterfly shape out of tissue paper and lay it flat on a table. Inflate a balloon and rub it on your child’s hair for a few seconds. Then, slowly bring the balloon close to the tissue butterfly. The butterfly will rise and stick to the balloon!

This is because rubbing the balloon creates static electricity, which attracts the lightweight tissue paper.

We understand your kid may be entering junior high any time which is why we have covered science experiments for children who are older than kindergarten kids, too. Here are a couple of easy science experiments for kids of older age groups-

1. The Shadow Game 

Everyday life provides many opportunities for this fun little game. Ask your child to investigate his shadow and guess where the light source comes from. What happens if he changes the shape of the shadow and takes objects like hula hoops and morphs it into different shapes? What happens if you change the direction the hula hoop is facing or if you move to a different spot outdoors or indoors? Explore this game with a lamp as well.

2. Backyard Detectives 

Take your kid out on a detective adventure to the backyard or a park. Ask him to explore different species of plants, bugs, insects, and small-sized animal species. Teach them to observe trees and look for signs of animal life there. Have the leaves been eaten or has the soil been burrowed? Ask questions aloud like, ‘I wonder what the ants eat?’ or ‘I wonder how the caterpillar moves’ will teach you kid about the structures of organisms and how they meet their basic needs. Ask your child to wonder about which animals take shelter where and when they come out. Document these changes and capture outdoor moments on camera every season to make memories and have fun exploring hands-on learning.

3. Playground Science

Take your kid to the playground and ask them to balance themselves on swings or play structures. Ask them to think about what they are doing and how long they are able to maintain balance based on different postures. Tell them to think about what happens when they push harder on the swing and why it happens. Playing on the swings will teach your kids about equal and opposite forces.

4. Weather and Structure Games 

When taking your kid on car rides or bus trips, ask him to describe the shapes and number of clouds, whether the sun is visible or not or where light comes from, the differences between manmade structures, and describing what the weather is like. These observations will model their senses and enhance their understanding of their surroundings. Ask your child to reason why the moon follows them at the night and explain to them why that appears to be so but is not.

5. Building Blocks 

Take your child to construction sites or places with bricks and stones. Ask him to look closely and notice whether the stone has multiple colors or how they differ in shape and texture. Explain to him how buildings are made and how the materials look and differ in their foundations. What kind of challenges do construction workers face during building constructions and why are the rooftops of houses slanted? These experiences will build your child’s observation skills and awareness of their environments.

6. Kitchen Experiments 

The kitchen is a wonderful avenue for developing a sense of measuring and observing how changes take place (foundations of chemistry). Children of this age are curious and want to help out in the kitchen. Let your child do that by encouraging him/her to mix ingredients, play with recipes, and watch how changes occur when two ingredients mix and heat up on the pan. Make scrambled eggs and pancakes in front of your child and allow them to observe how the fire changes the shape and color of the yolk and encourage him/her to describe what he/she is seeing.

7. Colored Flowers 

Capillary action is when water flows through small spaces without the help of gravitational pull or external opposing forces. This phenomenon is due to the high surface tension of fluids and it explains how a sponge draws water into it or how hair strands stay wet after a bath even if gravity acts on them. A fun experiment to demonstrate this is to take a bunch of white flowers, trim with angled cuts and place them in a cup of lukewarm water. Add a couple drops of food dye and coloring and let the flowers sit for a few hours, until they begin to change colors. Your kids will be left mind-blown with this experiment.

8. Homemade Slime 

Slime ranks at the top of childhood memories and who doesn’t have fond memories of watching Ghost Busters as kids? For this cool little trick, take a 1/4 cup of water, 1/4 cup of white school glue, and add a few drops of food coloring to the mix. Add borax solution to the glue and water and mix. Continue kneading till it results in a texture you like and remove the slime from your bowl or cup and have fun.

9. Paper Airplanes

Teach your kids a little bit about physics and origami by making a paper airplane. Let it fly and bend its corners to demonstrate how the plane changes its flight path.

10. Mentos Fun

This experiment is a little explosive in nature so make sure to stand back when watching it go. For this you need a can of diet coke and a mentos pack. Drop in a mentos (or two) in the can of diet coke can and watch it explode! Older kids absolutely love it!

11. Baking Soda Volcano

13. Balloon Rocket

Use a balloon, string, and a straw to create a rocket! Thread the string through the straw and anchor it between two points. Inflate the balloon without tying it off and tape it to the straw. When you let go, the air escaping will propel the balloon along the string.

This experiment teaches kids about action and reaction forces.

14. Egg in a Bottle

This classic experiment demonstrates air pressure. Hard-boil an egg and peel it. Light a small piece of paper, drop it into a glass bottle, and quickly place the egg on the opening. As the flame goes out, the egg will be sucked into the bottle!

This experiment shows how changes in temperature can affect air pressure.

15. Ice Cream in a Bag

Make a delicious treat while learning about the science of freezing! You’ll need a small zip-top bag, ice, salt, and a larger zip-top bag. In the smaller bag, mix 1 cup of heavy cream, 1/2 cup of sugar, and 1 teaspoon of vanilla extract. Seal it tightly. In the larger bag, fill it halfway with ice and add about 1/2 cup of salt. Place the smaller bag inside the larger one, seal it, and shake vigorously for about 5-10 minutes. The salt lowers the freezing point of the ice, allowing the cream mixture to freeze and become ice cream.

This experiment teaches kids about freezing points and the effects of salt on ice! Enjoy the tasty results together.

Kindergarten Science Standards Simplified

Much of what surrounds your kids every day is what makes up a good portion of the kindergarten science standards.

TIP 1: Play With Toys

The first thing a K teacher should do to get their students into NGSS is to start with toys and play! Gather yo-yos, toy cars and ramps/tracks, blocks, a wagon, marbles, etc and get the students playing.

We know young children learn best through play, so let’s use that to our advantage. How will playing help them learn science concepts?

Well the specific toys suggested above will all help students learn about forces and motion, pushes and pulls. This is a specific set of standards NGSS includes for the grade!

Now that your students are playing, talk to them about what is happening with the toys. Ask them questions like “what might happen if I push this faster?” “What about if I pull it slower?” You can foster conversation surrounding the play and the concepts! Then check those standards off your list! Easy enough right?!

TIP 2: Favorite Animals

Another suggestion I can make for K teachers diving into the world of science with their students is to use little kids’ love of animals to your advantage too! I have yet to meet a little one who doesn’t have a favorite animal! They can spout endless facts about on-demand. Kids LOVE animals!

Ask each student what his/her favorite animal is and what it eats, and you’re halfway there. You can talk about plants getting food from the soil, sun, and water!

TIP 3: Tricky Topics

You’re thinking, “ok, so far so good, but now I see that the NGSS standards want me to teach ‘Earth’s Systems’ to 5 year-olds and we’re not even sure that meteorologists understand ‘Earth’s systems’”. Have no fear!

All this means is we need to talk to our students about and make observations about the weather where we live. We can tie this into graphing and math, as many of us already do in our morning meetings, and we’re meeting some of the standards.

You can ask the students to have a dress-up day (who doesn’t love a good theme day!) and represent clothing needed for certain kinds of weather. Guess what? You’re meeting some of the standards!

Talk about the number of sunny days, cloudy days, rainy days in a month and compare the temperatures (warm/cool) from that length of time.

TIP 4: Integrate Topics

The final bundled of NGSS standards created for kindergarten is the group called “Earth and Human Activity”. This unit is going to bring your plant/animal learning and your weather discussions together!

To meet these standards you can begin to introduce the concept of food chains to the kids. You can talk more about what animals eat, what they need to survive, and how that changes or effects where the animals live.

This includes humans too! You can also discuss more why we have forecasters and why predicting the weather is important. (Take it back to your dress-up day and you’re set!)

Lastly, you can talk to students about conservation, recycling and protecting the earth to meet the final standard in this bundle. I have yet to meet a teacher that doesn’t do something with their students for Earth Day, be it a read-aloud, craft or picking up trash from the playground.

Take this conversation a tad deeper than you normally would and realize that not only did you just do some awesome hands-on teaching and integration, but you also just nailed the NGSS standards!
