We attempted to investigate the affect of different liquids on our teeth using eggs.

We attempted to investigate the affect of different liquids on our teeth using eggs.

Examine your eggs that you conducted your experiment on at home last week. If you were unable to do the experiment, watch the youtubevideo below and look which liquid had the greatest affect on the egg (teeth). You can still answer all of the questions in this lesson based on the video experiment.

Activity: Write the Date and L.O in your books. If you would like, you can draw a picture underneath your L.O of each egg after the experiment, labelling it with the liquid it was left in, or take a photo and print a picture to stick in your books. Write the sub-headings below and write your own findings with the liquid you used, or the liquids that were used in the video above. There is a teacher example on the next slide.

The egg In the water was the least affected because_____________________.I can therefore infer that ______________ is bad for our teeth and we should drink lots of __________ instead.

Underneath your last sub-heading, write another subheading entitled ‘reliability’.

What do we mean by the reliability of an experiment?

What could be done to increase how reliable our experiment was?

Reliability is how definite you are that the conclusion to your science experiment is correct.

The simplest way to improve the accuracy of any Science experiment is to collect as many results as you can by repeating the experiment.

Now you will write a sentence under your sub-heading to describe how you could increase the reliability of your experiment:
