Today students learned about capillary action. They learned that capillary action/wicking is the ability of liquid to move through narrow spaces, often against gravity. This is how most plants move water from the ground beneath them, up through their stems and into their petals and leaves. Since paper is made out of wood pulp we used it to demonstrate capillary action.
The students used colored water and paper towels to observe this process. The process of water moving along a conduit (the paper towel in this case) is called: capillary action. The paper towel is very ‘absorbent’: which means there are enough gaps in its fiber for the water to move through easily and quickly.

Today students learned that fire needs fuel and oxygen. When we take away oxygen the fire goes out. Students learned about vacuum. They covered a lit candle, which was placed on a plate filled with colored water, and observed that a vacuum was created when the candle went out. When the candle is lit the air in the glass gets heated and as the fire goes out the hot air tries to escape and a weak vacuum is created.

Students were asked if they could blow up a balloon without physically blowing air into a balloon. They were told that they could not use hand pump, or fill it with water. Almost all students thought this was impossible.
We then talked about chemical reaction - Chemical reaction happens when two or more substances react to form another new substance(s). For our experiment we used baking soda and vinegar to create carbon dioxide which filled up the balloon!

Today students learned about optical illusion and persistence of vision. Persistence of vision is an optical illusion whereby multiple discrete images blend into a single image in the human mind. Movies created on films and hand drawn animations use sequential pictures to create an illusion of a moving picture.
We created an optical toy known as thaumbtrope. A disk with a picture on each side is attached to two pieces of string or to a piece of stick. When the stick or strings are twirled quickly between the fingers the two pictures appear to blend into one due to the persistence of vision.

March 9,2017
Today students learned about Newton's third law of motion which states that for every action there is an equal but opposite reaction. We talked about rockets and the science behind it.
Students saw this law in action by blowing up balloons and noticing that as the air rushed out, the balloon moved forward.

Session 1
March 2, 2017
Today students were introduced to simple machines. They learned that simple machines are devices that make our job easier (i.e. we need to put less effort to get work done). Examples of simple machines are lever, inclined plane, pulley etc. Today we focused on catapult which is a lever.
The students built their own catapults and launched marshmallows using the catapults. We experimented with various sizes of marshmallows and tested how far (or how high) they launched.

Can you blow up a balloon without manually blowing air into it (you cannot use an air pump either)?
Today we learned about chemical reaction. Chemical reaction produces products (substance(s) that are different than the original substance(s)). We used baking soda and vinegar to create carbon dioxide to blow up our balloon!! We also tried the coke and mentos experiment (it did work, but not the way I envisioned it). We will try it again next time.

Today we talked about how rockets are launched and dipped our toes into Newton's third law of physics (for every action there is an equal and opposite reaction).
We designed our own rockets and launched them using straws! The students loved seeing how far they could get their straw rockets to go and had fun trying them out at all different angles.

Today students learned about siphon and its uses. They learned that a siphon is a device that allows liquids to flow from one container to another due to (atmospheric) pressure and gravity.
The students performed an experiment by creating their own siphon using plastic cups and bendy straw.

The first session will start on Thursday, January 19th.
You can expect your child to learn about weather, capillary action, gravity and volcano.
