WALT identify which liquid has the least effect on our teeth.

This week in Science we are setting up a fair test to see the effects of different liquids on our teeth.

We hope as many of you as possible can do this experiment at home.

For this you will need:

- 5 eggs (hard boiled is best)

- 5 different liquids (Water, milk, squash, cola and vinegar) 

- 5 cups

- a box with a lid (It might be smelly)


When we do investigations at school we need to write up our  ideas and findings.

You are going to write down your experiment following the steps below and finish writing it up next week once you have found the results.


Our Investigation:

We are going to investigate the effects of different types of liquid on our teeth. Thinking about which one has the least effect on our teeth.


We are using eggs because the shell on an egg is similar to the enamel on our teeth and the liquid will effect the egg shell in a similar way to how it would effect our teeth. 


The idea is to place an egg in each of the liquids like the picture below:


Let's write up our investigation and then you can set it up and look forward to finding out the results next week.


Use the following headings to help you write up your investigation correctly.


Write a sentence under each question and explain your answers. Try to include any facts you already know when you make a prediction.

Remember to list your equipment using bullet points. How much liquid will you need?

When writing the method, think about the steps that you will take to ensure your experiment is set up correctly.

We must always make sure we do a fair test. Which things are we keeping the same?

Which is the only thing that is changing?


Finally: Set up your investigation and draw a diagram to show what it looks like. Remember to add labels to your diagram.

WARNING: Remember to put your EGG-xperiment into a box with a lid as it can be a bit smelly after a week of waiting. 


Send us in a picture of your set up experiment.

Good Luck! wink



WALT: research effectively.

Zoom 1

Today we will be learning how to research effectively, using websites to find answers to questions. You will be using two reading skills, SKIMMING and SCANNING to find the information that you need.

Task: Using the word document below, can you find the answers to the questions using the web links provided? You might need to skim for key subheadings and get an idea about what the text is about. You will need to scan for key words from the question to help find the answer. Take a look at the example below.



Try to answer in full sentences like we discussed yesterday. You don't have to answer all of the questions  but the more information you find, the easier it will be to write a report.

WALT count squares to calculate area.

Zoom 2

Today we will be looking at a range of rectilinear shapes and will use the strategy of counting whole squares and half squares to calculate the area of each shape.

A  = 7cm²

B = 6cm²

C = 11cm²

D = 9cm²


TOP TIP - mark each square that you count with a dot SO you don't count it twice!

The rectilinear shapes below contain half squares which you can combine with another half square to make a whole square.

Shape A only has whole squares so would have an area of 12cm².

Shape B has two half squares which we can put together to make one whole square.  Therefore we can then add together 12 whole squares + 1 whole square (made from two halves) = 13cm².

Shape C has two half squares which we can put together to make one whole square.  Therefore we can then add together 10 whole squares + 1 whole square (made from two halves) = 11cm²
