7A investigate pressure

7A have been working on pressure and as a final investigation looked at the conditions that made water rockets go furthest.
Having predicted three key variables that might make the most difference they split into groups each testing one of these independent variables; amount of water in the rocket, angle of launch and size/shape of bottle. The dependent variable for all of these was the distance travelled.
You can see the testing in progress here:

After analysis of the results 7A concluded that there was one variable that made the most difference to the flight path and this was beyond their control - the wind. Why didn't Mr P choose a calm day to conduct this experiment?

Y6 visit the Millennium Seed Bank

Last Friday Y6 went to Wakehurst place to look for signs of spring in the gardens and to examine seeds in the seed bank.

First an intro from our Wakehurst teacher, Sharon

While sitting comfortably in the Millennium Seed Bank

We saw the biggest seed in the world, and the smallest.

Then out in the grounds to ask loads of questions.

And see lots of flowers, here on trees - Magnolia, pollinated by beetles!

Back in the seed bank checking out seed pods

And imagining a world with no plants.

Notes next to the Seychelles nut - biggest seed in the world.

Looking at the new arrivals in the seed bank.

They get prepared for cold, dry storage.

We also see what the scientists are doing.

Lots of seeds have been put out for us so we can see the wide range. Some are very useful, and tasty.
