Where do you buy genetically engineered seeds for a science project?

It might be difficult to buy genetically engineered seeds for a science project. The seeds are patented, so the company that created the GM seeds holds the rights to the seeds. Monsanto is one of those companies and in the past they have not allowed their seeds to be used for experimentation without their permission. You could; however, contact Monsanto or another company that has developed GM seeds and ask them if you could buy some for your project.

What are the advantages and disadvantages of true experiments?

Advantages:

  • Best design to establish causality
  • power to detect effects

Disadvantages

  • Internal Validity issues - confounds
  • Cannot examine some important social problems experimentally
  • External Validity issues
  • Construct Validity issues - We do not know which part of the operational or conceptual IV had an effect on which part of the operational/conceptual DV

What is a conclusion for a science fair?

A conclusion for a science fair would be that the students learned. Though who won, the trending project, and how many attended also could be used to make a statement.

How do you open a letter and seal it again without anyone knowing is was opened in the first place?

To open a letter discreetly, carefully use a thin, sharp object, like a knife or a letter opener, to slice the seal along the edge without damaging the envelope. Once opened, read the contents, then reassemble the envelope by aligning the edges and using a small amount of moisture to reseal the flap, ensuring it looks untouched. For added authenticity, you can use a bit of clear tape or a sticker that matches the original seal. Finally, handle the envelope gently to avoid any signs of tampering.

Only if you used a website or a resource to find out your information. If you fail to list these sources in the appropriate format (ask your instructor for directions) your projact may be disqualified for plagarism.

Is it possible to create a below freezing temperature inside a house or mobile home etc and sustain it for a day or so without being destructive IE cracking drywall wd flooring?

What causes the cracks is rapid temperature changes--if you were to leave the heat off for a week, then come home and turn the furnace on for a couple days, then leave for a week and so on, you'd get cracks. But if you were to let the house sit over the winter, allowing it to gradually change temperature, you'd be fine. (This omits the effects of mold.) This actually happens all the time--if a manufacturer builds a manufactured home in December and parks it in the storage yard until it sells in April, it will sustain freezing temperatures for several months without damaging it.

What do the letters of the R.E.C.A.L.L. method stand for?

Reason (why you did this)

Experimental design (procedure)

Call back data (reference to data)

Compare to hypothesis (compare the results to your prediction)

Analyze of the data (what does the data mean)

Lapses (errors)

Light Bulb (learned)
