Science lesson from Turkey

Introduction to Gases

Step 1: students wave their hands in front of their faces - they cannot see air but they can feel a breeze.

Step 2: we spray some perfume. Pupils raise their arms when they can smell it.

Step 3: students blow air into a plastic bag - air takes up space. 

Step 4: students wave a sound tube - sound vibrations are transmitted through air.

We learnt: air cannot be seen but you can feel it. Perfume can be diffused through it and sound vibrations can be transmitted through air - therefore air exits and takes up space!

Step 5: We put a candle in a container and pour water into it.

Step 6: we light the candle and put the open end of a glass over it.

We learnt: the flame goes out and the water level in the glass rises. The candle burns until it uses up all the oxygen. 

Science lesson from Estonia

The pupils of our year 1 class (1a 2012/2013) did their best to find out which objects sink and which objects float in a box of water. They worked very hard and had a lot of fun. Thank you Estonia for a fantastic lesson!

The children conduct the experiment and write down their findings on the board.

Examples of the notes the children took. They found out that cork, feathers, wax and styrofoam float and glass, graphite, metal, wood and rubber sink.

We really enjoyed this activity. As our oldest children are about 9-10 years old we had to do it with younger children but they had so much fun! I have a couple of videos but difficulties at the moment to put them on here. They will follow later :)
Hope you like the photos!

Science Lesson Swap - Finland

The Magnificent Breathing Machine

We have studied about breathing from our biology books and revised it first before starting the experiment. 5B is ready to do the science experiment.

The pupils wrote the instructions in their notebooks.

"I wonder how the finished product looks like?"

The groups needed a plastic bottle, a straw, two balloons and play dough.

The bottom of the bottle was cut off. "How much do we cut?"

"Do we only have to cut the top of from the balloon?"

"Hold on to the bottle, so I can slip the balloon to the bottom of the cut bottle." What a good idea it was to make a knot to the stem of the balloon before slipping it through.

                                         This is fun!

The balloon stays on the straw better when we tape it on to the straw.

Then the straw goes into the bottle, with the balloon going first in, and then the play dough which blocks the mouth of the bottle.

"Hey, this works. We thought we had to blow into the straw!" The small balloon will inflate the same as when you expand your chest and inhale air through the nose.

In the end, we wrote the results in our notebooks. Oxygen, the gas body needs, comes from the air. The lungs and other parts of the respiratory system remove carbon dioxide from the blood as a waste product. This excess carbon dioxide is exhaled.
