Finger Printing.

LI: Identify and group fingerprints into 3 main categories: arch, loop, whorl.

Aim:

Hypothesis:

Equipment: Pencil, Paper, Sticky tape

Method
1. Rub the side of a pencil lead back and forth on a sheet of paper to build
up the black area large enough to take 10 prints.
2. Press one of your fingertips firmly onto the black. Place the sticky side of a
piece of tape over your fingertip. (You may need a friend to help you with this.)
3.Tape the print to the correct location on the fingerprint form.

Chromotography experiment.

Lesson One - Paper Chromatography


Chromatography is a technique used for seperating mixtures. In all of the variations of Chromatography, a substance is placed onto or into a medium and then a solvent passes through the test substance, some of the test substance may be attracted to the solven and follow it up in the medium. Different types of molecules are transported different distances, causing them to seperate. In these activities, filter paper is the medium, solvent is the solvent and black ink is the test substance. Chromatography is used in crime labs to seperate the components of 'clue' substances such as blood, ink or other mixtures found at the scene of a crime. Chromatograms of these clue substances are then compared with those of the suspected sources.

Chromatography Today's date: Tuesday 10th May 2011

L.I I am learning the process of the chromatography and use this
to assist with solving the crime.

Aim: To use chromatography to distinguish which pen was used in the ransom note.

Hypothesis: I think that ......................because..............

Equipment - Beaker, felt pens, ransom note, filter paper, water, hand lens, masking tape and straws.

Method:

1. Gather samples of pens.
2. Draw a line across a strip of filter paper, 1-4cm from the bottom.
3. Attach to straw with masking tape.
4. Put filter paper in beaker, making sure the ink is at least 1-2cm above
the water.
5. Observe.
6. Remove filter when water has travelled about 3/4 of the way up the strip.
7. Compare results with the ransom note results.

Results -

Conclusion -

The _ pen wrote the ransom note because

Below are three different science experiments. You are to do all three in the time given. After you have completed each experiment your task it to write an explanation of what happened. Use different tools to help you explain - dictionary, internet, experts etc. This will all help you when you come to complete your science fair.

Curious Colors Experiment
Making a Color Disc Spinning Top

Materials you will need:

• Pencil
• A Glass
• White Card
• Cardboard
• Scissors
• Glue
• Ruler (for straight lines)
• A pair of Compasses
• Crayons or Felt Tip Pens
Watch as primary colors mix!




Steps:


  • 1. Stand the glass on a piece of white card and draw around the base of the glass to create your circle. At the same time draw another circle on the piece of cardboard.
  • 2. Carefully cut the circles out and divide the white card circle into three equal sized pie sections using a ruler.
  • 3. Color one pie section with blue, one with red and one with green.
  • 4. Glue the colored card disc on to the cardboard disc making sure that the colors are facing up.
  • 5. Make a hole in the centre of the disc (using a compass), so that you can fit a pencil through it.
  • 6. Make sure that you position the pencil so that the pencil tip is facing down and the color wheel is facing up with the pencil eraser end at the top. Slid/position the wheel around 1/3 of the way up the pencil.
  • 7. Spin the card on the pencil tip by positioning the pencil (top end/eraser end) between the middle of your palms with your hands flat together.
  • 8. Slowly roll the pencil between your palms allowing it to stop just at the end of one palm then quickly rub your palms together and release the spinning disc.external image cookchat%20&%20kids%20science%20021.jpg external image cookchat%20&%20kids%20science%20023.jpg

  • Step 7 Step 8
What color do you see when the disc is spinning and the colors are being mixed together? Our eyes cannot focus fast enough to see the different colors separately so they mix together and appear to be white.
The colors red, blue and green are called primary colors and they cannot be made by mixing other colors together. The other colors of the rainbow can be made by mixing a combination of the three primary colors together (red, blue and green).
Make lots of spinning tops using different combinations of colors. What colors do you see when you spin them?
When the spinner moves fast you see light reflected from all its colors, but your brain cannot separate them so you see a mixture of all the colors; which is white. Your spinner may look grey to you because your colors are not pure.













Experience Gravity Free Water


What goes up must come down right? Well try bending the rules a little with a cup of water that stays inside the glass when held upside down. You'll need the help of some cardboard and a little bit of air pressure.

What you'll need:
* A glass filled right to the top with water


  • A piece of cardboard


Instructions:
# Put the cardboard over the mouth of the glass, making sure that no air bubbles enter the glass as you hold onto the cardboard.


  1. Turn the glass upside down (over a sink or outside until you get good).
  2. Take away your hand holding the cardboard.


What's happening?
If all goes to plan then the cardboard and water should stay put. Even though the cup of water is upside down the water stays in place, defying gravity! So why is this happening? With no air inside the glass, the air pressure from outside the glass is greater than the pressure of the water inside the glass. The extra air pressure manages to hold the cardboard in place, keeping you dry and your water where it should be, inside the glass.







Test Your Dominant Side

Check out this cool experiment that will teach you more about how your body and brain work together. Test your dominant side by completing a series of challenges.

Which hand do you write with? Which foot do you kick with? Do you have a dominant eye? Do you throw with one side of your body but kick with the other? Are you ambidextrous? Answer these questions and much more with this fun science experiment for kids.





What you'll need:

  • A pen or pencil
  • Paper or a notepad to write your findings on
  • An empty tube (an old paper towel tube is good)
  • A cup of water
  • A small ball (or something soft you can throw)




Instructions:

  1. Write ‘left’ or ‘right’ next to each task depending on what side you used/favored.
  2. When you’ve finished all the challenges review your results and make your own conclusions about which is your dominant eye, hand and foot.
Eye tests:
  1. Which eye do you use to wink?
  2. Which eye do you use to look through the empty tube?
  3. Extend your arms in front of your body. Make a triangle shape using your fore fingers and thumbs. Bring your hands together, making the triangle smaller (about the size of a coin is good). Find a small object in the room and focus on it through the hole in your hands (using both eyes). Try closing just your left eye and then just your right, if your view of the object changed when you closed your left eye mark down ‘left’, if it changed when you closed your right eye mark down ‘right’.
Hand/Arm tests:
  1. Which hand do you use to write?
  2. Pick up the cup of water, which hand did you use?
  3. Throw the ball, which arm did you use?
Foot/Leg tests:
  1. Run forward and jump off one leg, which did you jump off?
  2. Drop the ball on the ground and kick it, which foot did you use?


What's happening?
So what side do you favor? Are you left handed or right handed? Left footed or right footed? Is your right eye dominant or is it your left?
Around 90% of the world’s population is right handed. Why most people favor the right side is not completely understood by scientists. Some think that the reason is related to which side of your brain you use for language. The right side of your body is controlled by the left side of your brain, and in around 90% of people the left side of the brain also controls language.
Others think the reason might have more to do with culture. The word ‘right’ is associated being correct and doing the right thing while the word ‘left’ originally meant ‘weak’. Favoring the right hand may have become a social development as more children were taught important skills by right handed people and various tools were designed to be used with the right hand.
Around 80% of people are right footed and 70% favor their right eye. These percentages are lower than those who are right handed and this could be because your body has more freedom of choice in choosing its favored foot and eye than that of its favored hand. In other words you are more likely to be trained to use your right hand than your right foot and even more so than your right eye.
It’s not strange to find people who favor the opposite hand and foot (e.g. left hand and right foot), and some people are lucky enough to be ambidextrous, meaning they can use their left and right sides with equal skill.
Try testing others and coming to your on conclusions about what side the human body favors and why.
Extra: Are you more likely to be left handed if one of your parents is left handed? What are some of the possible disadvantages for left handed people? (Tools, writing materials etc) Do left handed people have an advantage in sports?
Interesting fact: In 2009, only 7% of the players in the NBA were left handed while in 2008 around 26% of MLB pitchers were left handed.

Is it better to be left handed in some sports than others? What do you think?
