Science – Animals Including Humans: Teeth and Their Functions 🦷

Today we launched our new science learning all about animals including humans, with a focus on teeth and their functions. We began the day with an exciting scientific investigation linked to our learning question:

“What drink causes the most tooth decay?”

The children discussed their predictions and shared fantastic ideas about what they thought might happen and why. We looked at four different drinks:

• Milk 🥛
• Water 💧
• Orange juice 🍊
• Coke 🥤

Before beginning our experiment, we explored how to make our investigation a fair test. The children were introduced to the idea of variables and discussed what needed to stay the same to make sure our results would be fair and accurate.

We talked about:

• Keeping the same amount of each drink
• Using the same type and size of object being tested
• Leaving each sample in the drinks for the same amount of time
• Only changing one thing – the type of drink

The children were brilliant at thinking like scientists and asking questions. Throughout the session they used their scientific skills to:

• Make predictions
• Ask questions
• Observe carefully
• Discuss ideas
• Think about what might happen and explain their reasoning

To support our learning further, ask your child some of our science questions at home:

Ask us:

• What are the different types of teeth called?
• What jobs do our teeth do?
• Why do we need to look after our teeth?
• Which drink do you think will cause the most tooth decay and why?
• What does a fair test mean?

We cannot wait to continue our investigation and see the results. We are already developing our scientific thinking and becoming curious young scientists!

We look forward to sharing our findings with you soon.
