Making Gases

Here are some of the male members of the Language class.

We carried on our work on Science Language by making 3 common gases. Here is how the class described it:

Experiments
On Tuesday we did some experiments on making gases.

We mixed hydrogen peroxide and manganese dioxide and it made oxygen. We put a relit splint in the oxygen and it went into a fire again

We mixed magnesium and hydrochloric acid and it made hydrogen. We tested for hydrogen and it made a little pop when we lit it.

We mixed sodium carbonate and hydrochloric acid and it made carbon dioxide. We tested the carbon dioxide and it put the flame out.

____________________________________________________________________

First we got a test tube and then we got some hydrochloric acid and put some magnesium
Then we put our thumb on it and the pressure
Build up was were hard to keep your thumb on.
Then we put some more hydrochloric acid
With sodium carbonate and it was the same
Result as before I think.

Then we put some hydrogen peroxide and
Manganese dioxide which made oxygen
The End.

On Tuesday we did some experiment on making gases


We made hydrogen by mixing magnesium and acid together.

We made oxygen by mixing hydrogen peroxide
and manganese dioxide.

We made carbon dioxide by mixing hydrochloric acid and sodium carbonate.

The test for each gas is
Oxygen relit the splint
Cabin dioxide puts out the flame
Hydrogen exploded.

As always we appreciate your comments on our work.

Bob Marley or Elgar? Who should we listen to when we work?

Sound Experiment

In the second term we are looking at some of the keywords used in the Year 9 Science course. We started off with the words used in experiments:
Experiment
Variable
Control
Fair Test
Plan
Results
Conclusion
Evaluation

The class said that they wanted to do an experiment on music or cooking. So we looked at the effect of music on our work. I include here samples from the classes work unedited. They were asked to write up the experiment using all of the keywords.

ON TUESDAY THE 24TH APRIL WE DID A EXPERIMENT ON MUSIC, I DID A VARIABLE WORK. I PLAN SOME OF MY WORK, MY SECEND TEST I MADE IT A FAIR TEST. ONE OF US WAS THE CONTROL AND NOT LISTENING TO MUSIC. MY RESULITS WAS TEST 1 38/40 AND TEST 2 35/40. MY CONCLUSION WAS VERY GOOD AND I DIDN’T NEED A EVALUATION.

On Tuesday we did an experiment to see what music we work better on.
First we planned it and this is what we did….
For Test 1 (Bob Marley) then test 2 (Elgar).
We did the test then got the results and the conclusion.
To see what music what was better we had 2 math test with 40 questions on each and 7 min listening to each music.
We had the control which was S______ (didn’t listen to any music) and we saw if it was a fair test and what the evaluation was.
The results told us that we worked better with the Bob Marley music.
5 people did better in test 1.
2 people did better in test 2 than in test 1.
1 person did the same in both tests.
The control did better in test 2 than test 1.

We did an experiment on music and how it affects us doing work like the variables of our work.
There are two different kinds of music there was reggae and backing music
We had a plan to see the effect on the music had on our work.
The results of the experiment are here….

5 people did better in maths test 1 than test 2
2 people did better in test 2 than in test 1
1 person did the same in both tests
The control did better in maths test 2 than test 1.

We done an experiment on music and how it effects us doing work and also to see the variables
of our work. We had two different types of music, the first type was reggae and the second type was Elgar. The results of the experiment were
out of a maths test which was made up of two math tests.
The results were;
5 people did better in test 1 than in test 2.
2 people did better in test 2 than in test 1.
1 people did the same in both tests.
And the person on control did better in both tests.

We had a plan to see how the music effected our work. The whole experiment was a fair test because we only changed one thing and kept the rest the same. My conclusion was good so I didn’t need an evaluation.

On Tuesday we did an experiment about music to see how we had an effect on music
and the different variable are some people change on different types of music even people that don’t listen to music.
First we planed our music.
The results were 5 people did better in test 1 than in test 2
2 people did better in test 2 than in test 1
1 person did the same in both tests
The control did better in test 2 than test 1.
Conclusion kids work better listing to bob Marley and kids don’t work better than elgar.
