Weird Animal

DUMBO OCTOPUS

Found only at extreme ocean depths of 10,000 to 13,000 feet, Grimpoteuthis is a genus containing 13 species of octopus, whose webbed tentacles look like an umbrella when spread.

They’re known for the prominent ear like fins that jut out comically just above their eyes.

Though they’re found in deep waters all around the world,  they rank among the rarest of Octopus species.

Science Experiment

The Imploding can

Aim: To observe contraction in gases

Equipment: Aluminum can, Scissors tongs, Bunsen burner, heatproof mat, tripod, gauze mat, an open container of water.

Method:

1.Set up bunsen burner underneath a tripod and gauze mat
2. Pour approximately 50-60 ml of water into your can it should be no more than 1/4 full.
3. Heat the can of water until steam is seen escaping from the top.
4. Carefully grip the can with scissors tongsEnsure you have a firm hold of the can before lifting it off the gauze mat.
5.  Quickly, but very carefully, invert the can as you plunge it into a container of water.

Observation: As we put the heated can into the water upside down. It made a big bang as soon as it hit the water. But as it hit the water it scrunched up like somebody had stomped on it or like somebody scrunching a piece of paper.

Science Experiment

Observing Convetion 1

Aim: To observe convention in a liquid

Equipment:200ml beaker, Water, Tweezers, A crystal of potassium permanganate, A drinking straw, Bunsen burner, heat maty, Tripod and gauze mat.

Method:

1.Set up a bunsen burner on a heatproof mat.Put the gauze mat on the tripod but leave it just to one side of the bunsen burner.

2.Fill a 200 ml beaker with 150 ml cold water.

3.Place the beaker on top of the tripod and gauze and allow it to settle for a few minutes.

4.Carefully insert a drinking straw down one side of the beaker, ensuring the straw is touching the bottom of the beaker.Be care full as you do not want to disturb the water too much.

5.Using tweezers, drop a crystal of potassium permanganate down the inside of the straw. Wait for the crystal to settle on the bottom.

6. Very gently, So to not disturb the water, Remove the straw.

7.Light the bunsen burner slide it under the tripod so that you are only heating the outside of the beaker where the crystal, Observe.

Observation: At first when I put the crystal in I noticed that the color started spreading through the water as the heat started to make the chemicals darker (crystals).

Science experimtent

 Science experiment

Aim: To separate the different pigments in inks or dyes using paper chromatography.

Equipment: Test tubes, Felts, Tube racks, Paper

Method
1.Cut the paper into strips.
2.Put small circles near the bottom of the paper like 2 centimeters up with a felt.
3.Fill the test tube with about a cm of water.
4.Then place the piece of paper in the test tube and hang a bit of the paper off the side.
5. Then finally let the water absorb the felt.

Observation: Well firstly I saw the water run up the paper and absorbed the colour and finally reach two different colour as it was green then went to yellow and blue.

Science Experiment

Super saturation Experiment

Aim: To form a crystal from a supersaturated solution.

Equipment: Test tubes, Bunsen burner, Heat mat, Test tube tongs.

Method
1.Gently heat the test tubes until it becomes liquid.
2.Place in test tube rack for 30 minutes
3.Wait for the magic ingredient.

Observation: We observed that it went from ice to liquid.And then back to the ice.

Discussion:  We discussed the changeing off the Liquid.

Science Experiment

Aim: To investigate the solubility of baking soda ( Sodium hydrogen carbonate) and table salt 
( sodium chloride) to see which is the most soluble in water.

Equipment: 250 ml,Teaspoon,Salt,Baking soda, Copeper oxide.

1.Fill the beaker with water
2 Add a scoop of baking soda
3.Stir the solution until all of the baking soda had dissolved.
4.Repeat the steps again but stir until it hasn't dissolved but do it with all three Baking soda, Salt, And copper oxide.
5.Record how many teaspoons off all it took to not dissolve.

Results
Baking soda-5
Salt-9
Copper oxide-0

Discussion: When I put the baking soda in the beaker and stirred it around the first couple times it would dissolve and then I started adding more to one point it wouldn't dissolve same with the salt.

Conclusion:

This experiment showed that some solutes are more soluble than others in a solvent such as water.

Science Experiment

Making A Copper Sulfate Salt

Aim: To produce copper sulfate salt by reacting copper oxide with an acid

Equipment: Copper oxide powder, dilute sulfuric acid, measuring cylinder, 2x 100mL beakers, bunsen burner, tripod, gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.
Method

1.Add 20mL of sulfuric acid to a 100mL beaker. Heat to 70degrees. Turn off your bunsen.

2.Once heated, use a spatula to add pea-sized portions of copper oxide. Stir for 30secs

3.Repeat step 2 until no more dissolved.

4.Fold filter paper and place in a funnel. Place the funnel in the second beaker.

5.Make sure your first beaker is cool enough to hold and then pour it into the funnel. Gently swirl and allow to filter through.

6.Rinse the beaker and fill with 50mL of water and place on a tripod. 

7.Place evaporating basin on top of the beaker and pour some solution in.

8.Gently heat until the solution has reduced by half.

9.Take off heat and allow to cool.

Results and Discussion:When I was observing the second step I notice that the color started to get darker and as we got more into the experiment  the experiment we were doing started to get lighter  but to be honest I don't really remember what happened but when I came back to school it had turned into a light blue colour and into some sort of crystals.

Conclusion: This experiment involved dissolving a solute in a solvent to create a solution. 

Science Experiment

Science Experiment

Equipment: A tennis ball, Meter ruler and a clamp.

Aim: Make a brief statement of the purpose of your investigation.

In this experiment, I am to watch the height a ball is bounced from and how high the first bounce so I am observing both of the heights the ball is thrown from.

Hypothesis: Make a prediction of what you expect to observe during your investigation.

I expect to see that the ball will not come as far up as where I dropped it from.I think that it will be a little under from where I drop it from.

Method: Give a step by step description how your experiment is to be carried out.

Firstly I'll gather up the equipment I need, Secondly, I will set up everything up like the retort stand, Thirdly Ill place the ball where it should be, Lastly, ill watch how far the height that the ball bounces.

Key Variables

Dependant: I'll measure how high I drop the ball from.And the hight it goes.

Independent: I'll change the hight to see if anything changes.

Control: I'll be in control of my project and experiment.

Heights?

Dropped from                 

1) 100cm                         

2) 200m                        

3) 50cm
4) 70cm                                    
5) 10cm                           

Bounce

1) 52.5cm

2) 72.3cm
 3) 17.5cm 
4) 36cm
5) 13.5cm

Discussion: We discussed how our project turned out slightly different from what we thought. 

Conclusion: We came to the conclusion that it dropped a bit under what  I thought it would and that there is a difference between dropping in height and the bounce.

Evalouation:I think that we couldve been more foused on the project and maybe recored the results more.
