Science projects for class 4 and 5

Flexibility is a key property we look at as second grade students are learning about observable properties of matter in science. This simple flexibility science experiment is really more of a test and a fun one for kids. Read on to learn how we conduct this flexibility lab and add this easy science activity to your next properties of matter unit. Top 10 science fair projects for 4th graders The surface tension of a liquid is the tendency of liquid surfaces to resist an external force due to the cohesive nature of its molecules. The pepper flakes are so light, it floats on the water surface due to surface tension. The addition of soap broke the surface tension of water, but the water molecules want to keep the surface tension intact. So they pull away from the soap along with the pepper flakes. This pushes the pepper or “germs” away from your soap covered finger. This is why soap is such a great cleaning agent and so effective in cleaning dishes and taking all the grease and dirt away. 

Science fair competitions are an excellent opportunity to explore science. One of the of the premier science advocacy organizations, the Society for Science, is associated with more than 400 science fair competitions in almost every US state, as well as over 70 other countries, regions, and territories. You can find out if there's a Society of Science affiliated science fair near you! Class 3 Science Activity Kit Nothing gets kids more excited for science than hands-on experiments! Watch your fourth grade science students’ eyes light up when they try some of these activities. You’ll find physics, biology, engineering, chemistry, and more. These projects are easy to set up and really help drive the learning home. Get ready for some science fun!
