8 simple science experiments you can do at home

An experiment is a procedure designed to test a hypothesis as part of the scientific method. The two key variables in any experiment are the independent and dependent variables. The independent variable is controlled or changed to test its effects on the dependent variable.

STUDY. a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact. ObservAtion.

True experiments have four elements: manipulation, control , random assignment, and random selection. The most important of these elements are manipulation and control.

The steps to the Scientific Method are:

1. 1) Pose a Testable Question.
2. 2) Conduct Background Research.
3. 3) State your Hypothesis.
4. 4) Design Experiment.
5. 5) Perform your Experiment.
6. 6) Collect Data.
7. 7) Draw Conclusions.
8. 8) Publish Findings (optional).

Yes, you can re-use hot ice. You can melt it on the stove to use it again or you can microwave the hot ice.

Dry ice should never be placed into the mouth or swallowed. So as a rule dry ice should never be added to drinks to avoid any such risk.

While dry ice looks like it would be cold, it’s extremely dangerous to the touch and can cause severe burns. Dry ice is frozen carbon dioxide. Dry ice actually freezes your skin cells. The resulting injury is very similar to a burn and should be treated with the same medical attention.

When dry ice “melts” it releases carbon dioxide gas which could build up inside an airtight cooler and make it explode. Users must adhere to special usage instructions and safety precautions when using dry ice.

Yes but with a few considerations. It is so cold it can burn if it comes in contact with your skin. It can also burn the food if there is no barrier between it and the ice. A zip lock is not sufficient.

Generally speaking, 10 pounds of dry ice will last up to 24 hours in a standard 25-quart cooler—but there are a lot of factors at play. You’ll also want to consider the types of food you’re storing (frozen or refrigerated), the size of your cooler, any ambient conditions and the duration of storage.

Store dry ice in a cooler with the loosely closed. NEVER use an airtight container: the build up of carbon dioxide gases as the dry ice subliminates could cause the container to burst! Keep the cooler in the coolest, most well-ventilated area possible. NEVER store dry ice in your freezer!

1-2 blocks of dry ice will last 18-36 hours in small styrofoam shipping boxes. Dry ice can last up to 2-3 days if you use larger blocks and larger total amounts of dry ice. Some shipping companies can replenish dry ice during long trips to ensure your package never gets warm.

What Is the Dry Ice Formula? Dry ice has just one ingredient: carbon dioxide. Technicians create dry ice by pumping liquid carbon dioxide into holding tanks, which reduces the temperature to -109° F and pressurizes the substance into solid blocks or pellets.

Dry ice is the solid form of carbon dioxide (CO2). It’s called “dry ice” because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas.

Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods where mechanical cooling is unavailable. Dry ice sublimates at 194.7 K (−78.5 °C; −109.2 °F) at Earth atmospheric pressure.

While it’s almost certainly less expensive to get dry ice from a store, it’s possible to make it yourself using a CO2 fire extinguisher or pressurized carbon dioxide in a tank or cartridge. You can get carbon dioxide at several types of stores (sporting good stores and some cookware stores), or you can order it online.
