To complete this experiment the children had to figure out what the capacity of the bottle was using a measuring jug. They then had to quarter fill the bottle with water and figure out what two-thirds of the bottle’s total capacity was. They added this amount of vegetable oil to the water with 12 drops of food colouring. They broke the Alka-Seltzer into 4 parts and added them one by one, observing the effects. The children learned that the chemical energy from the Alka-Seltzer reacted with the water and produced carbon dioxide gas; which in turn tried to escape from the top.
Today the children constructed cubes, tetrahedrons and their own imaginative 3D shapes using marshmallows and cocktail sticks! They learned that squares distort easily, when put under pressure. When they compared the strength of the square to the triangle, the triangle won hands down! The triangle is the only shape that cannot be deformed without changing the length of one of its sides.
In this experiment, the children became aware of how moving air can make things move. Children were encouraged to Design and Make their own rocket when given materials such as A4 sheet of paper, straw, scissors, pencil (of approximately the same diameter as the straw), sellotape and measuring tape.The children launched their rockets a number of times, firstly estimating the distances traveled and then measuring them and taking the average distance in a controlled test. They drew a graph afterwards to represent their results.
Did you know? Rockets were invented in China over 800 years ago. The first ones were very simple – a cardboard tube packed with gunpowder and attached to a guide stick – a bit like the fireworks we use today!!

In this investigation, the children created a scale model of the earth and moon. They first estimated the size of the moon in relation to the earth and then the distance between the two. With the information that the moon is a quarter the size of the earth, the children proceeded to measure the circumference of the classroom globe using string. They divided it in fours by folding and inflated a balloon to correspond with the measurement. Knowing that the distance of the moon from the earth is 9.5 times the circumference of the earth, the children set about multiplying. They then measured that distance using a trundle wheel to display where the balloon or moon would be in relation to the earth in space.
