Science Week Report!!

1) Magnetic Cars 

Experiment

·         We made magnetic cars by sticking small circular magnets to our toy cars.

·         We got them to move using the repelling force between the poles of two magnets.

·         We then used three different magnets all different sizes to pull the cars along.

·         We raced out cars along our very own race track

·         We wanted to see which magnet worked best!

·      We had great fun at the science exhibition showing the other classes how to race the cars! We used the strongest magnets. 

How long is our race track? We measured with cubes. Can you guess how long? 

Results:

·      The bar magnet was the strongest

·      Our race track measured 11 cubes

·      Our pencils measured 9 cubes

·      The distance the cars travelled over the race track was longer then the length of our pencils. 

2) Static Electricity 

Experiment

·         We wanted to see which material was the best static

·         We used different material (wool, nylon, cotton, tissue, etc) 

·         We made it a  fair test (using same balloon, same  number of rubs, different material, how many pieces of tissue or Rice Krispies did each material

        pick up?).

We recorded our results on a bar chart. 

Results:

·      We found out that wool and nylon were the best "static's"

3) Moving Air 


Experiment: 

·         We moved different materials by blowing !!

·         We guessed which material would be easiest to move, and which the hardest.

·         We used straws to see if we could move the material by blowing it.

4) Strange sounds 

Experiment

·    We used a balloon and held it against our ears.  

·    We asked our partners to press their lips against the balloon and speak; then we swapped around. 

We had great fun in the hall, thanks to all classes and teachers  for teaching us lots of new things!!
