Genetic drift is the change in allele frequency from one generation to the next that occurs because alleles in offspring are a random sample of those in the parents, as well as from the role that chance plays in determining whether a given individual will survive and reproduce.

DNA mutation, Chromosomal mutation, and cell recombination are the ones you can view with a light or electron microscope. The book "Essentials of Physical Anthropolgy" gives more information about genetic drift and details about different ways of study.

Hope this helps!

It used to be you could do all sorts of stuff, like make stinky smells and make loud pops and bangs. These days everyone is so careful that there isn't much you can do. In any case, I use Google to find more details about the particular set you are thinking of.

1 decide what project you want to do.2 collect resources that pertain to that subject. 3 determine what variables you are going to use. 4 make list of the different outcomes from the different uses of the variable. 5 write your findings in a report that explains how you came to each conclusion

I patiently used Google Translate and got this. The instructions may not be in perfect English, but it's good enough to understand. Good luck :)

GROWING CRYSTALS
1.
experiments require a large measurement cup (at least 32fl oz / 0.9 1) Heat resistant glass mix the powder and boiling water. The vessel measures must be glass or plastic Resistant to heat. You also need a medium saucepan (at least 32 fl oz / 0, 9 1) to boil water. Separate carefully cut molds, as pictured. Make sure to leave a border around each mold. Also remove sharp edges from the edges with scissors.
2.
Use a large glass measure (at least 32 fl oz / 0, 9 1) (not included) to measure 0.68 liters of water and pour into a medium-size saucepan. Heat the pan until the water boils.
3.
Open the bag of potassium sulfate 10 (diamond frosting) with chemical crystal growth and pour the contents into the glass of measures.
4.
Pour boiling water in medium saucepan shot glass with the contents of the bag 10.
5.
Stir the mixture with the big stick until all the grains are completely dissolved chemicals. NOTE: Let the mixture cool for 5 minutes after the grains have dissolved.
6.
placed 2 rocks on the bottom base of the 5-sized plastic molds "C" of growth. These basement rocks should rise only about 3 / 4 "(2cm) from the bottom of mold growth.
7.
Pour the chemical solution / water shot glass molds in size 5 "C" for crystal growth. Make sure to fill each mold in the same way, leave an inch (8mm) of space between the liquid and the edge.
8.
After removing the bottle cap coloring dye, carefully cut with scissors (not included) the tip of the boat. Individual drops slowly drops of dye into the mold of crystal growth. see diagram following Mercedes to mix colors. Once you add the dye mixture solution with the small mixing stick. NOTE: Do not add dye to the mold of a glass. transparent crystals are better for the electronic.
9.
Place the mold of crystal growth in a place where not disturbed by movements or changes in temperature. crystals begin to grow in a matter of hours. let the crystals grow for three or four days without disturbing them. You can then remove the crystals from the solution. For best results, wash the crystals abundantly in the sink to remove excess dye and place on a newspaper or paper towel for a day to dry.
10.
if the mass of rock crystal and the base have been a square shape due to the structure of the mold growth, you can break the remaining crystals that form the block so that the crystalline mass display look more natural from the geological point of view. to expose the glass, LED lights the base by pressing the button on the bottom. transparent glass placed at the base and see how it changes color. if you are not using the base, be sure to extinguish by pressing the button again. to replace the battery, remove the cover with a screwdriver as shown below. NOTE: with the help of a magnifying glass, look closely at the detailed crystal structure of the crystals finalized.
Beak-shaped crystals: follow steps 2-10 with the following changes: In step 2, only 0.34 a boil water. In step 3, use the contents of the bag 11.
In step 6 uses the five molds size "D" of growth of crystals with a single rock in each base.
In step 8 uses color guidelines mold "D" (crystals spike) in the diagram below.
NOTES: replacement of the battery base. Place the base upside down. Now you can remove the battery cover to access it, as shown in the image below.

Well I have the instruction manual, but it is not too helpful. When I was a child I put fleas and ants on the slides, but I guess this microscope is different. Here is what my manual says.
How to make a prepared slide: If the given sample is not thin and transparent, it cannot be observed by the microscope as the light from the reflector or the light source does not pass through it. Fibers, pollen, wool, or salt can be observed easily and a cover glass is optional. Clear samples are stained first with a drop or 2 of methylene blue, Eosin or other dying solutions (not included).
1. TEMPORARY MOUNT: Wipe the slide and cover glass clean. Slice a thin sample with the micro-slicer (blade is very sharp...adult supervision). Pick up the sample with tweezers and put it on the center part of the glass slide. Put one drop of water on the sample using the needle that came with your kit.
2.PERMANENT MOUNT:Proceed as above, however, before covering the slide with the cover glass, add a few drops of gum media (not included, available at the store) or Canada balsam solution or transparent adhesive glue with a disecting needle to the slide. Push down on the cover glass with the tweezers to fix it in place and leave to dry for a day.
VIEWING LIVE BRINE SHRIMP:
1.Pour a small amout of brine shrimp eggs into the petri dish.
2.Add enough water so that the eggs are submerged and add just a dash of table salt.
3.Place the petri dish in a well lit area (under a lamp with a 60 watt bulb is good, for 24 hours).
4. When you see movement in the petri dish place it on your microscope stage, turn on the light and watch the brine shrimp in action.

Fill the barrel most of the way with stones, add coarse grit, add enough water to just cover the stones and then clean where the lid seals carefully. Seal it up and run it for a week, dump everything into a colander and rinse. Don't run that mud down your drain because it will plug it mightily, run it outside.

Do the same process with the fine grit, run it for another week and rinse and admire.

I used to have exactly that same rock tumbler. I have a bunch of polished rocks out in my garden that the kids and I made with that thing.

I don't have the instructions, but there are some perfectly great generic instructions on the geology.com web site: http://geology.com/rock-tumbler/rock-tumbler-instructions.shtml

I used these directions with great success.

Wow that is a nice one you have, it is probably quieter with the plastic cover. I use to tumble my rocks either in the basement or in an empty drawer in my dresser to sort of block out some of the noise. The one I had when I was younger was probably the first do it yourself old Smithsonian rock tumbler. I'd say that was probably one of the best gifts that I have ever received.
Well, first, you put the bag of rocks that you want to tumble in the tumbler. Make sure it only fills the barrel 2/3-3/4 full or you may have to extend polishing time.
then, usually you use the thickest to the thinnest grit in that order. You put the thickest grit in first and let the rocks tumble from 7-10 days (for optimal polishing). You will do this for each grit you use.

Make sure there is no grit transferred from one step to the next. Hope this helps :)

When a body covers equal distances in equal intervals of time then the body is said to describe uniform motion.When a body moves unequal distances in equal intervals of time or vice-versa, then the body is said to describe non-uniform motion.

Did you check the metal pin and spring terminals the batteries sit between? If a battery powered toy is stored with the batteries still in the terminals can corrode and block the electrical current from the batteries. Try cleaning the terminals with a cotton bud and Very Fine sand paper. A cardboard nail file works well for this.
