Science Buddies'
second grade science projects are the perfect way for
second grade students to have fun exploring science, technology, engineering, and math (STEM). Our
second grade projects are written and tested by scientists and are specifically created for use by students in the
second grade. Students can choose to follow the science experiment as written or put their own spin on the project.
For a personalized list of science projects,
second graders can use the Science Buddies Topic Selection Wizard.
The wizard asks students to respond to a series of simple statements and then uses their answers to recommend
age-appropriate projects that fit their interests.
If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults?
In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them!

Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! To do this, most people buy dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. You can dye eggs in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this science project, you will dye eggs with old or used…
