Balloon Day!

As a wrap up to our Science Unit on Matter, October 22 was dedicated to the properties of gas with Balloon Day!  Too start things off, we talked about some things they would like to find out using helium and regular balloons along with some other materials that had been provided.   

 Then the experiments began!  Some students used vinegar and baking soda to create a gas that could blow up a balloon while others tested how much a helium balloon could lift. Later on in the day, some students tried building balloon powered lego cars and rocket balloons with a piece of string. 

We had read the Robert Munsch story called Where is Gah-Ning? last week and we wondered if 300 helium balloons could really carry a person away! A number of other Science books gave more ideas to try with balloons.   Rubbing them to make static, twisting and tying them to make different shapes and letting the air out slowly were all self- directed experiments that the students tried out.  It was great to see them working together and helping to solve problems. 

Writing descriptive words was next and we will use these words to make sentences later in the week.

It was a fun filled and educational day in Grade Two!
