Life Cycles – The miracle of metamorphosis
Year 5 and 6 had the very important job this year of looking after our very own caterpillars as part of our Lifecycles topic. We knew that these insects were very special because they undergo a special type of transformation called a complete metamorphosis. We watched the caterpillars go through the first stage -called the eating stage – where they went from tiny to huge before our very eyes. Then they developed a hard outer shell around them known as a pupa or chrysalis. Finally we watched each of the caterpillars emerge as a completely new insect – a butterfly ! We looked after them for a day or so until their wings became hard enough to fly and we released them into the wild to start the lifecycle all over again. Now that’s magic!
Life Cycles – Living Things and Their Habitats
We have thought about how plants and animals reproduce. We closely examined a flower and identified the different parts and their functions. We found out about asexual reproduction in plants such as potatoes and strawberries. We then considered gestation times for a variety of creatures. Did you know, the longer a creature’s life expectancy, the longer the gestation period is likely to be? Finally, we considered the ways in which animals are adapted to their habitats in order to maximise survival chances and produce offspring to carry on the species! We learned about Darwin’s Finches on the Galapagos Islands and the differences in their beaks and food choices. We used a range of equipment as beaks. Have you ever heard of a Scissorbeak or Pegbeak bird? We have! We collected a variety of food types and had lots of fun, recording our answers in table form and interpreting the data to draw conclusions.
Properties and Changes of Materials
As part of this topic, the children have had lots of experiments to conduct during our science lessons. This week we have been separating materials. Firstly, we had to select the correct equipment for our experiment. Next, we carried out the investigation using techniques such as filtration, magnetic separation and evaporation. We really enjoyed finding out which technique worked best for each mixture.
Properties and Changing of Materials
Last week we looked at different materials and thought about their properties. We discovered that materials are chosen for particular products and jobs because of their properties.
This week we started to think about special properties of materials. We investigated whether some solids were soluble or insoluble (dissolved or not).
We tested lots of different solids including gravy, rice and sugar.
Next, we thought about factors affecting dissolving. The children came up with lots of ideas such as temperature, number of stirs, speed of stirring and size of particles.
I demonstrated, with the help of the children, how temperature affected the rate of dissolving. We created a line graph of the results.
Earth and Space
Circuits and Electricity
Children in Upper Key Stage 2 have learnt about several ideas relating to electricity this half term. They are able to draw simple circuit diagrams and label them. They are also aware of the history of the discovery of electricity, electric current and voltage.
This week the children conducted an experiment to explore the following question:
What effects do differing voltages have on a electrical component in a circuit?
The children tested how changing the voltage affected motors and bulbs in a complete circuit.
The children made predictions, collected results and formed conclusions.
