Is the sun good or bad? We looked at the positives and negatives of the sun. We then delved deeper into the how the sun can cause damage to our skin and to our eyes due to the ultraviolet light it emits.

 

We searched for our sunglasses and set up an investigation to prove that sunglasses can protect our eyes from the UV light. 

 

Using UV beads, we compared the beads in different conditions. We placed some inside (where there is no UV light), some in the sunshine (high UV light) and some under sunglasses outside (UV light that is blocked by a lens). The beads become brighter in colour the more UV light they are exposed to.

Class 2 have been learning all about sources of light and light reflectors. We turned off all of the lights and closed the blinds so it was as dark as it possibly could be then explored different objects. We could see the light sources extremely well in the dark but the light reflectors we couldn't see until we used a light source to reflect off the material. We all got very excited when we got the glow sticks out and lit up the classroom!

 

We had great fun sorting different items into light sources and light reflectors then some of us got onto the challenge which was to design a dog jacket in order for it to keep safe when walking at night.

In Science, Class 2 explored how we need light to be able to see. We discussed different sources of light, both natural and man-made. We also thought about what would it be like if it was dark and we had a power cut. We discussed whether the fact that some councils are turning off street lights between 12am and 5:30am and whether we thought it was a good idea.

Class 1 have been learning about carnivores, herbivores and omnivores this week. The children began by investigating different ways they might group animals. After learning our new key vocabulary and spending some time learning what foods different animals eat, the children group animals according to their diet.

How do plugs work?

 

We had great fun being electricians this week!

 

We took wired plugs and unscrewed the plug case to reveal what was inside. We learned all about the function of the three wires and why every plug has a fuse. We reflected on previous lessons and discussed the material used for the plug case and flexible cable and related to whether they are conductors or insulators. We were all really pleased that the cable and plug had a plastic covering as we know that this is an insulator and protects us from the electric current.

What conducts electricity?

 

To begin this project, class two experimented with circuit components in groups to try and make complete circuits to make a bulb light up. We also included a motor and a switch.

 

We then thought of objects and materials that we would like to test in the circuit to see if they let electricity flow through them. We know that these materials are conductors and have low resistance and those that do not allow electricity to flow through are insulators and have high resistance. 

 

We made a prediction for each material and then tested it out. We were very excited when we included the lockers as part of our circuit and the bulb lit up!

We have had a busy week this week in Science! We had great fun testing our hearing. We played music at a low decibel up to music at a high decibel. Each time we played a quiet or loud sound, we measured how many steps we could get away from the sound source until we could no longer hear it. We concluded that the louder the sound, the further away we were able to hear it.

Super understanding from class 1 to know that all animals needs water, food, air and shelter to survive.

In science we have been learning about food chains. We have investigated what foods butterflies like to eat and made some butterfly food to see how many butterflies came to visit. We have also spent time creating our own food chains.

This week, year 3 and 4 have been labelling different parts of the ear and matching their function.

Class 2

We carried out lots of experiments this week to understand how sound is made.  We recorded our observations using labelled diagrams and written explanations.     We found it fascinating when the rice bounced on the cling film when we made a loud bang nearby and it was great that we understood how and why this happened.

In Science, class 2 looked at the volume of different sounds. Using sound meters, we listened to sounds we could hear around the school and recorded the volume in decibels. We also had great fun making loud sounds with the musical instruments!
