We have been working on carrying out a fair test to investigate orbit times.  We used a ping pong ball tied to a string to model a planet and its orbit. We changed the size of the string so it was a smaller or larger orbit and then timed how long the orbit would take.  We will now look closely at our results to determine if we can prove that the further the planet from the Sun, the longer the orbit time.

The Big Question

‘Is there a pattern between the size of a planet and the time it takes to travel around the Sun?’

 

We explored the planet fact cards to look for patterns and relationships.

We worked with a partner to investigate and explore the different phases of the moon. We used our ping pong balls on sticks to model how the moon moves round the Earth and to help us understand why the moon appears to change shape throughout the month.  We then worked in small groups to use Oreo biscuits to represent the different phases of the moon.
We have been learning about how flowers reproduce.  We dissected a lily to explore the different parts of the flower.
We worked in small groups to sort the life cycles of different animals that had become muddled up into the correct order.  This helped us to explore the similarities and differences between the life cycle of different classes of animal.
We have started finding out about the life cycles of amphibians.  We will be finding out next about insects so that we can then compare the life cycles of these different classes and find similarities and differences.
We have been working scientifically in Beech class.  We worked in groups to measure our current height, then used the World Health Organisation growth charts to plot where our height would be.  We could then make a prediction on what our height might be when we are an adult.  It was interesting to compare results in our class. 

Gestation Gurus

 

We played a game to see if we could work out the different gestation periods for different mammals, including humans.  We learned that gestation is the process by which a mammal grows a baby and is the time between conception and birth.  Once we had worked out the correct gestation periods for different mammals, we were challenged to spot any patterns in the results.  We realised that there was a link between the size of the animal and how long it carried a baby for before giving birth.  

In most cases, the larger the animal the longer period of gestation.  Therefore, the smaller the animal, the shorter gestation time. 

We had a great time celebrating Roald Dahl day with some themed Science experiments.  First of all, we enjoyed making our own BGF inspired dream jars and observing over time what happened when we mixed oil, water, food dye and alka seltzer.  We then made our own phizzwizards, again inspired by the BFG.  What a fun afternoon we had!
