Year 4 Spring Learning

 

Science

 

This half term, as a year group, we were going to start our new topic in science all about teeth and digestion.

Please use the below to assist with your home learning.

 

You could start with using a hand held mirror to look at your own teeth. What do you notice about the teeth? Are they all the same or different? Do you think specific teeth have specific jobs to do when eating?

 

You could eat an apple and see what marks are made. Compare your teeth marks with other members of your family. Do you all make similar teeth marks or different? Why do you think this might be?

 

Please find some links below which will be useful to find out about the topic.

You may find a way to present the types of teeth or the digestive system as a whole. Get creative and send your pictures to school via our Facebook or Twitter pages!

 

An egg-cellent idea for an experiment

 

If we were in school we would be carrying out an experiment to test which liquids cause the most damage to our teeth to determine the best liquids to drink.

 

You could try this at home - if food resources are spare. You will need some eggs and different liquids. Egg shells are ideal to represent our teeth as their shell has similar qualities to our own teeth enamel. Suggested liquids could be water, milk, a fizzy drink, cordial and vinegar. You would need to hard boil the eggs and then leave them in containers covered with each liquid. 

Don't forget to think about a fair test! You can explain to an adult what this means. Think about the variables and don't forget to make a prediction!
