Science Experiments

The rock cycle is the natural process in which rocks transform from one rock type into another rock type over time, a type of natural recycling.

Igneous rocks, which are formed from magma cooling underground, or lava above ground are formed from previous igneous, metamorphic, or sedimentary rocks which have become melted, usually as a result of plate collision and subduction.------->

When these igneous rocks are exposed to weathering and erosion, they break down into smaller particles that are transported by wind and water to a place of deposition, where they can form into sedimentary rock strata, through a process of lithification, where excess water is squeezed out by overburden pressures and the particles are cemented together by various minerals precipitating out of solution. Igneous and metamorphic rocks can both be turned into sedimentary rocks in this way.------->

Igneous and sedimentary rocks can also be changed by heat and/or pressure into metamorphic rocks, by transforming their existing mineral structures into new minerals or realigning the existing minerals. There are different degrees of metamorphism, so even an existing metamorphic rock can become a different metamorphic rock. -------->

If these metamorphic rocks are melted, then solidify, they become igneous rocks, and the cycle starts all over again.

The rock cycle is largely driven by lithospheric plate movements which cause subduction and uplift, also by climatic conditions and the associated erosional elements.
ignious forms right from the lava, while sedimentary forms from different things even from organic particles and metamorphic format from ignious and sedimentary and changes by the extreme pressure and force between it and other colliding influences, you can tell these rocks apart very easily if you know how they are formed.
Lava and Magma are liquified rock and are made from intense heat and pressure and when they are cooled at different factors (temrature/how quickly/pressure).

They form different types of rocks and these rocks get weatherd and recycled over large peroids of time.
In nature, there are 3 types of rocks: metamorphic, igneous, and sedimentary. Metamorphic rocks form when heat and/or pressure are applied to another rock. An igneous rock is a rock that is formed by cooling magma. Finally, a sedimentary rock is formed when other rocks are weathered down by rocks and water and the particles that come off them as a result of this are compacted and cemented together to form a new rock. A mineral can form in two different ways: it can crystallize from cooling magma, or it can crystallize after a solution that it was dissolved in evaporates.

• Determine what problem or question you hope to answer with your project. This question or problem should be something that could reasonably be determined through your own home-based experimentation. For instance, you can't answer a question through experimentation such as, "What is the long-term effect of alcohol on a person's liver?" But you could answer a question such as, "How does alcohol affect the growth of plants?"

  After deciding on the question, form a hypothesis, or your own educated guess, as to what the answer is. Write out your hypothesis, explaining what you expect to happen during the experiment and what the result will be. Explain the reasons behind your hypothesis

  Write the steps necessary to complete the experiment. An experiment contains control and variable factors. Control factors do not change, so that the effect of the variable factors can be observed. For instance, in an experiment to determine how alcohol affects the growth of plants, you use the same type of plants, planted at the same time, in the same type of soil, receiving the same amount of sunlight, but given different amounts of alcohol in place of water. In this experiment, the type of plants, soil, sunlight and time are all control factors while alcohol and water are variables.

  Observe the experiment's progress and keep detailed records of your observations in a journal. Take measurements and quantify the progress using numbers. For instance, during the experiment using plants and alcohol, you might notice and record differing colors or conditions of a plant's leaves, but also measure the growth of the plants using a ruler or weighing them with a scale.

  At the conclusion of the experiment, analyze your observations and use them to determine whether your hypothesis was correct. Write a conclusion describing what you found. Were you surprised by the results? Would you like to repeat the experiment? What would you do differently? Theorize about the reasons for your results.

• After you have finished the experiment, prepare a report, including your problem/question, hypothesis, experiment procedure, observations and conclusions. Write in complete sentences and present the typed report with a professional-looking cover. Include pictures taken during the experiment and create colorful graphs or charts to summarize your observations.

  For a science fair, purchase a foam core trifold board to display your report. Use color to highlight the title at the top of the project. Attendees should see at a glance your project's outcome, so concisely summarize your sections to print and glue onto the board. If the rules permit it, display portions of your experiment. For instance, bring the plants labeled with how much alcohol they received and place them on the table in front of the standing trifold board.

  If asked to give an oral presentation about your project, bring note cards with summaries of the main points of your project. Only include the most important or most interesting points about your project if there is limited time. Keep the complete report nearby in case you need to refer to it during a question and answer session. Take deep breaths and practice to calm your nerves.

Explain what you did in the experiment and use scientific words for extra marks. It also has to explain the outcome like how did the baking soda and vinegar explode when they were together in a bottle. Also explain what you would change about the experiment if you were to repeat it. I.e. how would you improve it? What measurements would you use? You could also explain how successful you think the experiment was and why.

Things you could include:

• Whether repeating the experiment would have made the results more reliable
• Whether any of the equipment broke or faltered
• Whether it took too long to complete the experiment
• Whether you had all of the equipment
• Whether you completed every instruction/correctly conducted the experiment

Make sure your evaluation doesn't become a conclusion or set of observations, by saying what happened by way of reactions etc.

process of seed germination

1. the testa breaks

2. the radicle comes out first and grows downward. It will become the first true roots

3. the plumule grows upward. It will grow into the first true leaf

4. The cotyledons which are the sources of food get smaller

5. the roots get settled on the soil, the cotyledons drop and the young seedling continious to grow.

No. Experiments can be done anywhere. Laboratories are indeed handy as they have equipments and surroundings needed for most of the experiments, but you cannot limit experiments to the labs.

The answer to this actually depends on how you define the word laboratory.

If by a laboratory, you mean 'a special room set aside to conduct scientific experiments' then the answer is no. Experiments can be conducted in the field (in other words, outside the lab or even outdoors) in what is known as field research.

However, if you define a laboratory as 'a place in which experiments are conducted' (as in, "The whole world is my laboratory") then the answer is yes. By this definition, wherever you happen to be conducting your experiment - the classroom, the beach, the International Space Station, or even inside your own head - would be considered your lab space.

The way you've phrased the question, however, makes me believe that you intended the word laboratory to have the first definition, i.e. a lab room. By that definition, the answer you're looking for is false, for the reasons outlined above.
