Y8 test the spring toys

All of Y8 got involved in spring toy testing over the last few lessons. This is part of their energy studies.
Spring toys were primed and then the height they jumped up into the air was noted. The Elastic Potential energy was converted into first Kinetic and then Gravitational Potential energy.

 

Which is the spring toy and which the bouncy student?

They used the iPads to record the highest point of the flight.

The App was slopro so they could scrub through the action to find the highest point.

Here is a primed toy ready to spring.

We also need to know the mass so the force can be calculated

Then complicated calculations need a computer

The force x the distance (N x m) gives us the energy in Joules

All tests were conducted in a fair, accurate and reliable manner.

And lots of toys were tested so a good comparison could be made

Most of the spring toys actually appear as a blur on these photos



Sometimes jumping toys come as a bit of a shock, even when you were expecting them!

Y6 meet the maggots

During their investigation into the life processes Y6 checked out whether maggots are sensitive to light.

First shine the light from one side

What do the maggots do?

Then shine it from the other side

What happens now?

Do the maggots always do the same thing?

Now try from overhead. What happens in this scenario?

Re-capture your maggots and reset the experiment each time.

Count how many went which way.

Compare results with your classmates.

And note down the results.

Every group found their fastest maggot

So we could have a maggot race at the end of the lesson. (My money is on lane three)

And then all wash hands before lunch.

7A check out Photosynthesis

7A started their work on photosynthesis by investigating how water gets into the plants and then up to the leaves.

Some microscopy was involved

They looked at the roots with the microscopes to see if they could spot the root hair cells that help absorb the water from the soil.


The they set up carnations with ink and water to drink!


Ink was put into one pipette bulb and water into another

the selected flower stalk was bisected with much care

Full sets of fingers are required for the rest of the work!

Once the stalk was divided along its length the ends were placed in the two pipette bulbs

Some ink needed topping up

And then flower arranging could commence.

Now we leave it for a few days and see the result

What do you expect to happen?
Watch this space.

8A investigate energy changes.

In their recent science lessons 8A have been looking at energy changes in different situations.

A solar cell

A motor

Of course they record all of their results.

Lighting a match

Firing a catapult

Shaking nails in a coke can

Lots of activities for everyone.
