Our Gliders

Today, we made our own aeroplanes, then made another type of gilder to compare.

Experimental:

1) Cut the index card or stiff paper into 3 separate pieces that measure 2.5 cm by 13 cm.
2) Take two of the pieces of paper and tape them together into a hoop.
3) Use the last strip of paper to make a smaller loop, overlapping the edges a bit like before.
4) Tape the paper loops to the ends of the straw as shown below. The straw must be lined up on the inside of the loops.
5) Now hold the straw in the middle with the hoops on top and throw in the air similar to how you might throw a dart angled slightly up. With some practice you can get it to go further than many paper airplanes.
Think:

1. Does the placement of the hoops on the straw affect its flight distance?
2. Does the length of straw affect the flight? (You can cut the straws or attach straws together to test this)
3. Do more hoops help the hoop glider to fly better?
4. Do the hoops have to be lined up in order for the plane to fly well?

Deadline: 10 p.m. 3rd March 2013 Sunday

Was your aeroplane better than the experimental glider?

Garbage Enzymes

After the CNY break, we are using our leftover Fruit peels to make garbage enzymes!

Exciting!

Garbage enzymes!











What are garbage enzymes? What are the benefits of using them?

Enjoy the process of collecting and making them =)

Think about the Science behind it.
Post your comments & questions here!

Cheers,
