In Science, we have been learning about the human digestive system and the children have just loved all the gross parts, including talking about poo and vomit! To investigate the effects of different liquids on our tooth enamel, including sugary drinks such as Coke, we used eggs in cups of different liquids and observed the shells after 3 days. Miss Cashmore overheard one child say “I am never drinking Coke again” after they saw the decay of the egg shell! We found out that milk and water had no effect on the egg shell and so are the most sensible drinks to have to prevent tooth decay.
We also looked at food chains and food webs, including working in teams to create our own food chain display cards, showing the transfer of energy from the producer up to the apex predator in each chain.
In Science, we have been learning about the states of matter: solids, liquids and gases. For our investigation, we explored different melting points of foods. Miss Cashmore used a tea light and a stand to heat foods such as: butter, chocolate, coconut oil and cheese in a foil cup. We used a digital thermometer to measure the temperature at which each food began to melt. We found out that coconut oil melted at the lowest temperature (around 30 degrees Celsius) and cheese had the highest melting point (around 60 degrees Celsius). We now understand that melting points are the point at which a solid turns into a liquid when heated.
