A Mixture Of Problems

Learning Intention: To find more than on way of solving each problem.

Cheek cells under the microscope.

Today room 4 were looking at cheek cells. We wanted to see what our cheek cells would look like under the microscope.

Hypothesis: We will see some of the organelle.

Equipment: - Lolly pop stick
                   - Slide
                   - Sodium Chloride
                   - Methylene blue (stain)

Method: First we took the lolly pop stick and rubbed it on the side of our cheek. Then we put it on a slide, he added a drop of sodium chloride and a drop of methylene blue to stain it.

Observation: I saw the membrane, little circles and tiny line like figures.

Why Should We Ban Animal Testing???

Why Should We Ban Animal Testing

Animal testing is when scientists test products on animals. Animal testing should be banned because vertebrae animals could be extinct, animal results are not transferable to humans, and animal testing could be replaced with alternative methods.

Vertebrate animals could extinct due to animal testing. In the U.S, more than 100 million animals are used in animal testing each year. Over 100 million animals that are used in animal testing are burned, crippled, poisoned, and abused every year in U.S. labs.

There is no point in animal testing because the results cannot be 100% transferred to humans. An example of this is how edible chocolate can be eaten by humans but not dogs. Aspirin is a household medication taken by humans for pain relief, but this is poisonous for cats.

Animal testing could be replaced with alternative methods. Human tissue sampling and computer modelling. But sadly scientists like to test experiments on innocent animals instead.

Animal testing is cruel, over 100 million animals are being used in animal testing every year. Animal testing can be replaced with human tissue sampling and computer modelling, however, scientist still prefers to test on animals.

Technology wood.

With the help of a pencil I designed a sketch of 8 designs. Oh each design it had to have a housing joint, that has to be possible to create.  I then had to choose one of the designs.

I then wrote a paragraph that explains the reasons for my choice as to why I chose that design: 'What is it?, Why choose it?, Why choose this one?, What is it for?, Who is it for?, How will it be used?, Where will it be used? Is there anything I have to consider for its safe use?'.

I used a bench hook, mallet, tri square, steel ruler, backed saw to make a full size working drawing of my box because .

I used a steel ruler and a tri square to copy the measurements from my drawing onto the piece of wood.

I marked a square line (120) across and using a steel ruler and a tri square.

I cut off the first piece of wood using a machine that cuts wood.

I then marked out the housing joint using pencil, tri square and steel ruler.

Hard Materials_A joint

First I cut the wood 190cm, then I drew joint outlines so I could cut the outline to make a joint, after cutting the join I put to wood pieces to put in the joints. A joint is what connects to pieces of wood together.
