Science
In science today, otters learnt all about the importance of looking after our teeth. We conducted an experiment by putting eggs into different liquids to see what the effect might be. An egg shell is similar to the enamel on our teeth. What do you think will happen?
In Science today, Otters learnt all about human teeth and their functions. We learnt that Molars are used for chewing and grinding food, Incisors are used for biting and cutting food and Canines are used for tearing and ripping food. We then made a mouth, using marshmallows as the teeth and labelled the different types.
In Science, Otter class went on a walk around the field and mystical garden looking for different habitats and the animals that live there.
Otters had a brilliant science lesson today. We went on a sound walk to note down all of the things we could hear, where these sounds were coming from and what materials these sound waves needed to travel through. We then made our own string telephone!
We started our learning on 'Sound' this week by identifying how sounds are made, associating them with something vibrating. We organised the classroom into different workstations. On each table, we set up one of the sounds to investigate: tuning fork in water; rice on a drum skin; ruler clamped to a desk; elastic bands to twang; stereo speakers to feel. In groups, we then had to discuss what was happening and why.
The children are continuing their learning on States of Matter in Science this term. So far this term we have discussed what life would be like without solids, liquids and gasses. We then conducted the 'Dancing Raisin' experiment by putting some raisins in some lemonade. We then watched the raisins 'dance' up and down in the lemonade. We had some very interesting observations from the children, including
'The bubbles, which are made of gas, stick to the surface of the solid currants. They float up through the liquid lemonade to the surface. The gas bubbles burst, and the solid currants sink to the bottom of the liquid again'.
Today in Science, we discussed why some solids act like a liquid. We looked at sand, salt and rice and discussed how they can flow like a liquid and take the shape of the container. However, we agreed that they are still solids as they are made of small particles that can be poured but this doesn't make them a liquid. Well done Otters!
In Science, we have been discussing the process of evaporation. We were introduced to Glenn and his garden pond. He was frustrated that he had to keep refilling it when the weather is hot. The children therefore had to help him to find a way to reduce the amount of water that is evaporating away from his pond. We had some fantastic ideas, some of which really thought about how the water cycle works. Well done Otters!
This week in Science, we discussed the process of evaporation and condensation. We then made our own 'Solar Still' to turn salty water into drinking water!
In Science this week, we discussed the water cycle and made our very own water cycle in a bag!
