Cool Science Demos for Kids

2nd grade is a great grade to be in. This is the year that your science education really starts to take off. This is also the year that you will be introduced to many fun and cool science demos like getting an egg into a jug, buoyancy demos, magnet demos and chemical reaction demos.

Cool science demos can address a number of science concepts. Popular 2nd grade science experiments often times explore science topics that relate to common items like pennies. Because of this, cleaning pennies science projects are very popular. These projects look at how tarnish on a penny, created from copper oxide, can be dissolved using an acid and salt. For example, you can use Pepsi to dissolve the tarnish off of a penny or you can use ketchup, which contains both vinegar (an acid) and salt.

Another type of fun 2nd grade science fair projects that you can expect to watch is the getting an egg into a jug experiment. In this experiment you will be using air pressure to suck a hard boiled egg into a small mouthed jug. While this is a very simple experiment, you need to have an adult to help you as it involves the use of matches.

Buoyancy is another science concept that you can expect to work with in your 2nd grade science class. Buoyancy demonstrations will show you have items with the same mass will have different buoyancies. For example, a piece of wood with a mass of 10 grams will float while a rock with a mass of 10 grams will sink.

Magnets will also be used for cool science demos in your 2nd grade class. The first magnet experiment or demo that you can try is an anti gravity experiment that uses a gravitron. Gravitrons use magnetic repulsion to levitate items. Other magnet experiments include identifying polarity and using magnets to create electricity.

Cool science demos used for 2nd grade science fair projects can focus on a number of science concepts. For example, they can be chemistry science fair projects or they can be biology science fair projects.

Chemistry super science fair projects are particularly popular in the 2nd grade, particularly ones that utilize household products like pop, baking soda, vinegar and salt.
