G5 Science homework

Dear G5 students, this is your homework.
Please find luminous, reflector, concave, and convex materials in your home.

1. Find some luminous object that able to produce its own light!
2. Find any materials that can reflect light (the bouncing back of light)
3. Lens is a two-sided piece of transparent material with one or both sides curved. Find any concave lens (a lens that is thicker at the edges than in the middle, making things look smaller).
4. Also find the convex lens (a lens that bulges toward the viewer, making things look smaller).

Submit to me on Thursday, September 15, 2016.

Special Homeworks

Dear students, this is a special homework only for Grade 2 up to 5:

1. Please do your homework for additional point in your Science progress report.
2. Prepare the simple materials. You don't have to buy the new one if you have the old.
3. While you are doing your experiments, Take a picture or video each step and the result..
4. Make a science experiment report.
5. Submit your homework at the latest on May 21, 2016!

Grade 2 - Air Pressure Experiment

1. Does Air Have Weight?
   To begin these air pressure experiments wave your hand back and forth in the air. It's easy to move your hand around because air pressure is pressing onto your hands in all directions. Air actually weighs 14.7 pounds per square inch at sea level. That means that every square inch of your body is being pressed on by 14.7 pounds of pressure.
2. Materials
   Balloons
   String
   Scotch tape
   Ruler(stick or clothes hanger may also be used
   Needle or sharp pin 
3. How to do:
   Cut three strings approximately 12 inches long.
   Blow up two balloons so they are the same size. Tie a string to each balloon.
   Tie one of the balloons to each end of the ruler tight enough so the string will not slip.
   Tie a string loosely around the center part of the ruler so that you can slip the knot back and forth until the balloons are balanced.
   Tape the string in place so it will not move when the balloon is deflated. Prick one of the balloons with a needle or sharp pin.
   Watch how the ruler moves upward on the side where the balloon was deflated. If this does not happen it might be because the center string was not tight enough and moved when the balloon was deflated.
   Try the experiment several more times to see if the experiment works consistently. This is the way real scientists do their work. They test their hypothesis several times to make sure the same thing happens consistently.
4. Extending the experiment
   Try these air pressure experiments. Balance two deflated balloons on a ruler or stick. Take one balloon off the stick and inflate it. Return the balloon to see what happens. Try balancing several balloons on a yard stick. When you have the yardstick in balance. Predict what you think will happen if you deflate all the balloons, one at a time, from left to right. After writing down your prediction, try this air pressure experiment.

Grade 3 - Salt Crystals Project

1. Can you grow Your own salt crystals?
   Have fun growing your own salt crystals with this simple project. You can do further research with a microscope in KiCS  LAB once you’re finished. Crystals are beautiful to look at and you might even want to start your own collection.
2. What you'll need:
       A jar
       Water
       About half a cup of salt
       A spoon for stirring
       String
       Scissors
       2 toothpicks
3. How to do:
       Fill the jar with water.Add about half a cup of salt to the water.
       Mix the solution together with a spoon.
       Cut a piece of string with scissors and tie each end to a toothpick.
       Place the string over the top of the jar so that the string dangles into the middle of the solution and the toothpicks hang over the edge.
       Don’t forget to clean up when you’ve finished.
4. Observation:
   Crystals can be found grouped together as lots of small crystals or as huge individual crystals. When you look at your crystals, you can examine the differences between them: Are they perfectly formed? What shape are they? What color? Can you see any microorganisms on the crystals?
5. How it Happens? Write in your science experiment report!

Grade 4 - Ice Cube Experiment

1. The Lifting Ice Cube experiment demonstrates the melting and freezing properties of water, which results to another property of matter called adherence. Adherence refers to close physical attachment or union of two objects. To further understand this phenomenon, let us do your science experiment!

2. In this experiment, you will need the following materials:
       Glass of water
       Ice cubes
       String
       Salt
3. How to do
   Drop an ice cube in the glass of water. Take the string and dangle the end of it on the ice cube, and then keep it still.
   While the string is dangled down onto the ice cube, sprinkle a bit of salt on the ice cube.  Set aside for a few minutes. After some time, try to lift the string and observe what happens to the ice cube.
4. How it Happens? Write in your science experiment report! ..

Grade 5 - Make a teabag fly
You'll never look at teabags in the same way again

1. Construct a rocket from a tea bag? Well you can and it’s easy!
   But be warned - it isn’t quite as spectacular as a NASA shuttle launch.
   Remember - always ask an adult for help with matches and don't do this experiment near any flammable materials.
2. Materials:
       Tea bag (must be stapled at the top)
       Matches or lighter
       Non-flammable plate or ceramic plate
       Water or fire extinguisher (just in case!)
3. How to do:
       Remove the staple, label and string from the teabag.
       Pour the tea into a bin.
       Unfold the teabag.
       Turn the teabag into a cylinder - make sure there's a space in the centre. You can use your finger if that helps.
       Stand the cylinder on one end on a plate. Make sure it's on a flat surface.
       Use a lighter or match to set the top of the teabag cylinder on fire.
4. What will happen and how it happens? Write in your science experiment report

   Remember! 

1. Take a picture or video each step and the result.
2. Make a science experiment report.
3. Submit your homework at the latest on 11 May 2016!

Exploring Home Work - Growing a Plant from the Seeds

Grade 3 student have a fun homework. Your already gave to you the red bean seed and a corn seed. You have to plant it in your back yard or in a small vase. Wait until it grow. Take a picture with camera or with your cellphone. Save it and send to mr. Wesly.
