Science Day at St Giles School


We arranged our science day to coincide with British Science Week, a celebration of science, technology, engineering and maths, which runs from the 10th-19th March.

The theme for this year’s British Science Week is ‘Change’ so each class explored and investigated this in different ways.

Class 1 and 2 spent the morning investigating changes in materials. They started by observing butter, chocolate, ice cream and salt and discussing their properties then made a prediction about what would happen to each one if they were left out during the morning. They also put some coloured ice cubes in baby oil and made a prediction about what would happen if they too were left out during the course of the morning.

The rest of the morning was spent investigating the fastest way to melt ice to free some Lego, how to make the biggest bubbles using a range of soap products, which materials mix with water and which don’t and they even made ice cream in a bag!

Here’s how to make ice-cream just like the infants did.

Class 3 spent the morning investigating energy from the wind, the sun and wood with Mr Edwards, a parent, a governor and STEM ambassador. “What resources does the Earth have that we can convert to useful energy?”

Renewable energy is energy generated from natural resources— Wind, Waves and Solar energy such as sunlight, wind, rain, tides and geothermal heat—which are renewable (naturally replenished).Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and biofuels for transportation.

Mr Edwards showed that the windmill used a dynamo to turn mechanical energy into electrical energy.

Here Mr Edwards shows Class 4 a water wheel.

One thing the children did learn was that renewable energy isn’t always reliable. They wanted to use the stream for the water wheel but there wasn’t enough water running through it to turn the wheel.

Class 4 discussed how inheritance and environmental factors influence who we are and how we look. Which are definitely influenced by inheritance? Which are definitely influenced by the environment? Which could be influenced by both? Class 4 discussed whether all traits are inherited or if environment influences how we look and who we are. Mrs Rogers showed her class some pictures of her family and how there are even some similarities between her and a member of her family from hundreds of years ago.

They asked which traits we definitely inherit. Which are definitely influenced by the environment? Accent, language, scars. Which could be influenced by both?

It was explained how genes are inherited and how each parent has 2 copies of every gene and that one of these genes is passed to the child. They investigated inheritance using counters and discussed their findings.

Here is what the children did.

  • Each pair needs a set of coloured counters: 6 of one colour for the mother and 6 of another colour for the father. Use a marker pen to write the genes from Table 1 onto the counters

  • e.g. for mothers hair type, write ‘t’ on one side and ‘T’ on the other side.

  • Repeat for all traits, one letter on each side for both the mother and father.

  • Place counters together in a plastic cup, describe what the counters represent and how flipping them will give a random selection of what is passed to the child.

The investigation helped Class 4 explore which features of the parents the children will inherit.
