This year we have undertaken a number of scientific experiments to test our theories and to actively learn new concepts and ideas. Take a look at some examples below.
Living Things
Some of us were holding our noses as we learned about the digestive system by recreating what happens in each part of the journey. Mashing and mixing with saliva in the mouth, mixing with acid in the stomach and finally removing the nutrients and water in the intestine (we strained our mixtures through socks!).
Materials and Change
We learned about heterogeneous and homogenous mixtures by making fruit salad and smoothies. A heterogenous mixture, like our fruit salad, is composed of separate parts that are easily separated. A homogenous mixture like our fruit smoothies is a mixture that forms a uniform composition as all parts are evenly mixed together. It is not easy to separate a homogenous mixture.
Properties and Characteristics of Materials
We became kitchen detectives as we worked together to discover which of four white substances was flour, sugar, citric acid and baking soda by using our knowledge of acids and bases. We used litmus paper to check our predictions. Can you spot the citric acid? Clue: Look for the litmus paper that turned red!
Electricity
Our static electricity can races were both exciting and informative as we saw static electricity in action. When the balloon is given an electric charge it will attract the can. It was their job to move the can from the start line to the finish line using only the balloon’s charge. To charge the balloon the children had to rub it on their hair or clothing.
