Year 4 Science day

We have spent the whole day today doing Science! We began the day by setting up our experiment looking at how different liquids affect teeth. We placed hard boiled eggs in plastic cups and submerged them with different liquids. We used coke, Diet Coke, water, sparkling water, orange juice, vinegar, black currant cordial and lucozade. We will leave the eggs for 24 hours and then observe any changes.

Next we looked at the digestive system. We worked in groups to try and draw the system and label it. Then we created poo! This helped us understand what happens to the food we eat and what the digestive process is.

After that we used a disclosing tablet to identify where plaque gathers on our teeth. We had fun trying to scrub it off and had purple tongues for the whole afternoon.
