Teachers, this one’s for you! If you’re on the hunt for exciting science projects suited to 1st graders, look no further. Follow along as we unpack 25 possible projects to enjoy with your class. Your students will learn scientific fundamentals about the world around them- best of all, they’ll be doing so in a fun and memorable manner!

1. Color Mixing 

Teach your students about primary colors and how they mix to form new colors. Fill an ice tray/ cups with water and use food dye to create red, yellow, and blue cubes. Once frozen, place 2 primary color cubes together in a larger container, watching them melt and reveal their new color.


2. Celery Science

Discover how quickly plants drink their colored water by placing food-dyed water into a cup and placing a leafy stalk of celery in it. After 1 day, come back to the project and observe how the leaves on the stalk have changed in color.


3. Playdough Bones

Build 2 playdough bodies- one with and one without bones (short straw supports), and ask your class to compare the two. Explain the following to your students: As the straws act as supports and keep the one body up, bones do the same for our human bodies- allowing us to be strong and not as weak as jellyfish.


4. Molecule Monster

Introduce your class to molecular or structural changes by making slime. Demonstrate that when certain ingredients are combined, their properties may also change.


5. Magnetized Money

Make science fun by exploring the magnetic properties of US dollar bills.


6.Blubber Buffer

Explore the effects of temperature on animals and how they keep warm. Cover the inside of a plastic bag in vegetable shortening and then place a gloved hand inside of the shortening bag. Then place your hand in ice water and discover that fat forms a protective layer.


7. Paper cup Phone 

This fun experiment, using paper cups, teaches children about how sound waves travel.


8. Solar Crown Creation

Solar science hats are the perfect way to introduce outer space to the class. Color, cut, and paste the planets, in order, onto a pre-prepared crown.


9. Electrified 

Blow up balloons and teach your class about static electricity. Challenge your students to see how much of their hair they can get to stand up and what objects they can lift using the electrically charged balloon.


10. Lava-lamp Creator

Mix water, oil, and food coloring together in a bottle. Drop-in 1 antacid tablet, close the lid, and watch the chemical reaction. Compare the soluble and insoluble reactions of the liquids.


11. Sprout House

Introduce plant science by having your students plant seeds and create a sprout house.


12. Apple Volcano

This simple chemical reaction experiment is one that is sure to wow! Mix together baking soda and white vinegar and watch the magic unfold as your apple volcano erupts.


13. Weathervane Creation

Explore weather science and direction by creating your very own weathervane using inexpensive household items!


14. Water Floater

Investigate the idea of density by evaluating what floats in different types of waters.


15. Slingshot Rocket

Help develop engineering skills at an early age by engaging your class in fun engineering activities such as building slingshot rockets.


16. Ladybug lifecycle

Explore natural science themes by analyzing various animal and insect life cycles.


17. Temperature tester 

Introduce the concept of temperature by making a thermometer. Mix water, alcohol, oil, and food coloring in a jar. Place a straw in and use molding clay to secure it in the jar so that it rests 1” from the bottom of the jar.  Move the jar between hot and cold temperatures and watch the liquid level rise in the straw.


18. Bouncy bubbles

Create a  bubble solution by mixing dish soap, corn syrup, and water together. Use a baster to blow into the mixture and help create bouncing bubbles.


19. Fountain maker

Discover more about the expansion of liquids and gases whilst you learn to make a fountain.


20. Rock-on 

Non-porous objects and properties are perfect points of study when analyzing rocks submerged in water.


21. Melting Crayons

Teach your students about melting points, solids, and liquids by creating a wax painting. This experiment is great for combining both science and art projects into one fun lesson.


22. Marble Momentum

Set out to roll a marble down a ramp in order to bump and move a folded card. The further the card moves, the more momentum the marble has gained.


23. Rock candy

This edible rock classification is sure to rock the socks off your 1st grade class! Growing sugar crystals is one of the best experiments for kids. Learn more about crystal and rock development by conducting the experiment below.


24. The floating egg experiment

Learn about density with the help of everyday kitchen ingredients and materials.


25. Colorful Chromatography 

Draw circles of color on coffee filters, add 5ml of water, and then watch as the colors start to disperse.


Take these science activity ideas into your own classroom and develop an exciting way in which 1st grade science class is conducted! Inspire your students to learn in a hands-on manner and help them conduct simple experiments that dramatically increase their physical science knowledge!
