Borax Crystal Ornaments

Is it Christmas time already? Let’s create some homemade crystal ornaments with the kids. Kids will learn some science while decorating the Christmas tree with ornaments they create. In this experiment, we will use a saturated solution made out of Borax powder. This is a perfectly safe experiment for kids under adult supervision. You can …

Fun Milk And Vinegar Plastic Experiment

What Is Plastic Made Out Of? What happens when you mix milk with vinegar? What is plastic made out of? What do stone, buttermilk, yogurt and cheese have in common? So many questions I had in mind after researching for this milk curdling experiment. There are various experiments and articles online that indicate mixing milk with …

Color Science & Art | Coffee Filter Flowers

Is black really black? What happens when all the rainbow colors blend together? We will be able to answer these questions after doing some science investigation. In this experiment, we will use coffee filter to investigate color properties. We will make a beautiful bouquet of flowers along the way, too! It’s a combination of a coffee …

Does Water Conduct Electricity? Simple Experiment

“Don’t touch a switch with wet hands!” We were all taught that since we were little kids. It does seem like water can conduct electricity and that is why we shouldn’t touch any electrical outlet or switches if our hands are not dry. Does water really conduct electricity? Let’s find out by doing a simple controlled …

Sugar Water Rainbow | Density and Air Pressure Experiment

Density is the amount of substance (mass) within the volume occupied by the object. If two cups have the same amount of water (i.e. same volume), the one with more sugar is denser than the one with less sugar. Buoyancy is determined by relative density. The solution with less density floats above the solution with …

How Are Ocean Currents Formed | Water Convection Experiment

How Are Ocean Currents Formed Ocean currents are formed in several ways. They can be created by wind, by gravity, by events such as earthquakes. They can also be made by density differences in the water. Density in the water changes when temperature or salinity varies. In this experiment, we will investigate how temperature can affect …

Can A Raw Egg Grow? | Science Projects With Eggs

In this experiment, we first see an acid-base reaction. Eggshells contain calcium carbonate which is a base while vinegar contains acetic acid. When you submerge an egg in vinegar, an acid-base reaction causes the calcium carbonate to break down into their calcium and carbonate parts. The calcium ions (as in calcium acetate) stay dissolved in …

Photosynthesis And Respiration In Plants

What is Respiration in Plants All living things use a process called respiration to get energy to stay alive. Cellular respiration in plants is the process used by plants to convert the glucose made during photosynthesis into energy which fuels the plants’ cellular activities. On the other hand, photosynthesis is the process where light energy …

Grow A Crystal Angel Ornament – Science Experiment

One of the most salient properties of water is its ability to dissolve other materials. In this experiment, you will dissolve Borax powder into the water to create a saturated solution. A solution is saturated when no more powder can be absorbed. Water can dissolve more powder when it is hot. In this experiment, you …
