Science Experiments

The bottle begans to fill with water and begans to float.

Because fingerprints can add a considerable mass to the crucible when weighing it.

Watson and crick and the discovery of the double helix

cfc's react with ozone and deplete it. and ozone protects the earth from the harmful uv rays of the sun. so with the ozone layer depleted, earth and life on earth is exposed to the harful rays and causes various ailments and also leads to global warming

This is a physical change due to the fact that you are adding two substances.

It can have as many as it needs. You can even change different variables at the same time and study their individual influence with proper statistical tools in many type of experiments.

The three variables of a science project are:

1. Controlled variable: A controlled variable means the part of the experiment that stays the same. This is also called the dependent variable.

2. Manipulated variable: A manipulated variable is something that can be changed by the experimenter. Also known as the independent variable.

3. Responding variable: A responding variable is the variable which you have to measure to get your results. So, you do not know the values of this variable until you measure it.

A typical experiment must have following parts:

Introduction

Materials

Procedure

Data

Data analysis

observation

Conclusion

You can also include your name on the top of the experiment.

If necessary date, suject name and the instructor's name can be added as well.

No, Evangelista Torricelli did not receive any awards during his lifetime. However, his work and contributions to mathematics and physics have been widely recognized posthumously, with various honors and accolades named after him.

When doing an experiment, it is best to have two groups a "control group" and the "test group". The test group is the group tested on while nothing is done to the control group. This provides a means of determining what, if anything, the effext of the test are.

Adhesion.

Scientific Method: Asking a question - the main reason for your experiment is to find something out. Ask it here. Forming a hypothesis - the format of If..., then..., because... Which states what you think will happen and why. Testing the hypothesis - this is the actual experiment or test. Analyze data to form a conclusion - interpret the results and then come up with your final statement on what happened. This should answer the original question unless your experiment was unsuccessful. Analyzing data may also include making a chart, table, or graph.

Mass and Volume are physical properties that can bed measured. By themselves, neither can bed used to identify unknown objects or substances. However, if you have measured the mass and the volume of an object, you can calculate its density.

I honestly don't know. However, I saw some answers to that question on Ask.com. They weren't very accurate, (I don't know the answer, and I know that) but it's better than nothing, right?

Get some glow-in-the-dark paint, or self-adhesive sticker material.

A microscopic view of onion skin will show several rectangular cells, each with a small, spherical nucleus.

Is there a connection between age and pulse rate?

That's the one I used and i got it right

Independent variable, is variable that the experimenter manipulates

Nothing.

The fruit does not generate the electricity. The differing electrochemical potentials of the metals used generate the electricity; the fruit is just there to provide a conductive path and some electrolytes.

Through nuclear fusion of hydrogen to form helium

Yes

Mighty Bond super glue typically contains ethyl cyanoacrylate as the main ingredient, along with polymerization initiators and stabilizers. It may also include other additives to improve adhesion and performance.
