Review 9 sience

UBCO trip!

My perspective of the day   (Which was totally awesome!!!)

On April 19, my sister and i went to the UBCO campus with our co-op group.

First we went to the chemistry lab, and made elephant tooth paste. Then we popped balloons with gases in them like carbon dioxide, oxygen, hydrogen, ect. I held a broom with the hydrogen filled balloon on the end. My friend Morgan held a meter stick with a match on the end. The balloon popped and hit me in my face, it was really scary because when it popped it popped out flames. I was okay though.

After chemistry we went to the biology lab. There we learned about flat worms( planaria ).

We got to conduct our own experiments on the flat worms (no planaria where harmed in the experiments). In one of the experiments we did a control experiment ( control experiment is so you can compare what they do normally to what you changed ) then we put a peace of cow liver in the center of the dish.i found that it takes longer than 5 minuets for them to notice it. We also did an experiment where we covered half of the dish with aluminium foil so half was dark, then we put a lamp over it. I found that the flat worms went strait for the darkness. 

Then we had lunch and cupcakes. (yum!!) 

After that we got a tour of the campus.   

 Then we got to look at an electron scanning microscope. We saw a lady bug eye, a beetle foot and a bruised apple. The bruised apple had millions of bacteria living on it. We learned that there is to arms on bacteria that helps them move around in water. I also learned that a regular microscope has the resolution up to 100nm. A electron scanning microscope has a resolution 0.1nm. 

At the end we made ice cream out of liquid nitrogen. We learned that it is safer to not where gloves when handling liquid nitrogen. we also got touch it! we where not aloud to cup our hand because it pools and then starts burning your skin, but if you have the palm down and it spits it wont hurt.

After we eat the ice cream we poured the rest on the floor, and it made little liquid nitrogen orbs that if you touch them they split and dissolved. 

I had a super fun time at UBCO. 

Here is exactly what we did.

Chemistry Session approximately 1 hour

-overview of lab safety: glasses, fume hood, fire blanket, eye wash station, shower, close-toe shoes, long pants

-hypothesized about reactions of various gases (contained in balloons) to heat and oxygen

-discussed observations using knowledge of chemical make-up of the gases

-observed and participated in making of cold and hot packs by first keeping 2 chemicals separate and then combining them with a shaking motion as we do with store-bought packs (shaking breaks the barrier between the 2 chemicals, allowing them to combine and react, resulting in endo- or exo-thermic reactions

-elephant toothpaste demonstration: chemical reaction of a catalyst and hydrogen peroxide, resulting in an exothermic reaction

-slime: polymers (long chains of molecules) with ammonia added, resulting in a chemical reaction/connection

Biology Session approx. 1 hour

Focus: how to design an experiment using flatworms, including hypothesis, establishing a control, identifying variables (light, protein/food), recording observations, discussing results and considering the variables which may have affected their results

-brief discussion on possible uses of the study of simple invertebrates (genetics? cloning?)

Liquid Nitrogen Ice Cream

-learned of the unit Kelvin for absolute temperatures

-The secret to the creamy ice cream is all in the rapid freezing of the mixture. The liquid nitrogen causes the fat and the water particles to stay very small, giving the ice cream its creamy consistency.

Tour of Campus: what they viewed

-students studying for finals all over campus

-gymnasium (set up with desks and partitions for final exams)

-greenhouse

-lecture hall: students sat in seats; brief demonstration of how screens are used by professors to enlarge data; learned how students use a device to register attendance, answers to questions by teachers which get sent to each individual student's file

SEM (electron microscope)

-students were shown various items magnified to at least 1000x the university's usual microscopes

-learned some of the applications of being able to magnify to such a degree (eg. by engineering students)

this is the biology lab where we learned about flat worms.  

Making slime in the chemistry lab

In the chemistry lab, making a chemical reaction making the vile freeze to the wood plank

                     

                         

               In this picture and the next picture, my friends are conducting an experiment to see how the flat worms react to light an dark

                                                                    This is us in the lecture hall.

This is when we made ice cream out of liquid nitrogen. 

after we dumped the rest of the liquid nitrogen on the floor. It made little orbs that evaporated when you touched it.

Dear Mr Fuhr,

     Congratulations on becoming an MP. 

     I have some concerns about oceanic pollution. I believe that this problem is getting serious. Soon the ocean is going to be so full of chemicals and toxins that it will cause fish and other organisms to die, water will no longer safe to drink, and coral reefs will disappear. The toxic build up in fish is slowly poisoning our bears. The whole earth relies on the ocean’s ecosystems, if those systems collapse almost every other ecosystem will also fail. I think this problem can be fixed with some work and time.

     If we used less harsh chemicals in shampoos and cleaners, natural fertilizers, and were smart about how industry uses water, we could get started on fixing ocean pollution. Maybe to get people motivated to do these things, there could be Government sponsored environmental advertising. We also need more government regulation of toxic chemicals in Canadian manufacturing.These are just some of the things we could do. I hope this letter helps this problem be fixed.

     I am looking forward to your reply. 

     Respectfully, Shiloh Marriott

Coral reefs report.

Coral reefs 

BY Shiloh Marriott 

 November 9, 2015  Introduction 

Coral reefs are one of the most populated habitats in the ocean world. A coral reef has lots of amazing organisms living in and around them. These organisms are biotic (which means living). There are also a-biotic (meaning non-living) things that play a role in coral reefs. Wether it is good or bad, we also have a substantial influence on coral reefs. Coral reefs are very intriguing habitats and organisms. 

Biotic 

Coral is made of little animals call coral polyps. polyps are transparent, but look colourful because of the algae living in side them. This algae gives them most of there energy by preforming photosynthesis so it can provide food for it and its host. Coral polyps, which look a little like a upside down jelly fish, use it’s tentacles to sting and eat small prey. There are many types of coral like, cones, soft coral, hard coral, and etc.  Coral takes years to grow. When multiple kinds of corals live by each other is called a coral reef. Coral reefs are home to many organisms. There are over 1,500 species of fish living in and around coral reefs such as, clown fish, butterfly fish, sea anemones, green turtles, octopi, squid, sea urchins, clams,  sharks, and so many more. But what do they eat? Well lets start at the bottom of the food chain. Plankton for example, makes it own food from the energy of the sun. This is called a producer. Then sea slugs , witch eat plankton , are called herbivorous consumers(herbivores). Then Octopuses, witch eat the sea slugs, are called carnivorous consumers( carnivore). Then sharks, which eat the octopuses, are called secondary carnivorous consumers. That is one of many food chains in coral reefs. 

A-biotic 

Have you ever thought how waves can affect coral reefs? well they do. Waves help wash away waste and bring food like plankton. The temperature, witch is also important, can  be 77 to 84 Fahrenheit ( 25 and 29 celsius).  Coral reefs are found in shallow waters and can be found 60 meters deep ( 197 feet), but some coral such as hermatypic coral can be found deeper than that. Coral reefs, witch are found in warm, clear waters, are near the equator in the tropical zone and are home to 25% of all ocean organisms, covering less than 0.1% of the ocean surface. 

Mans impact 

People use coral reefs in many different ways, for example, coral reefs are good tourist attractions, good fishing spots, and some of the fish are used in aquariums. But a lot of coral reefs are under to climate change, cyanide fishing (for aquarium fish), blast fishing, oceanic acidification, sunscreen use , water pollution( can cause too much algae growth),  and over use of coral resources. But there are ways to fix these problems. And there is way you can help like, try to use natural shampoos and dish soups ( because your water will eventually get into the ocean), reduce, reuse, recycle, try not to litter, and you can learn more about coral reefs and see for your self of what you can do. Coral reefs are very fascinating things to learn about.

Conclusion 

We know lots about coral reefs. We know about how the biotic and a-biotic elements affect them, we also know how we affect them, and how much we need them. But there is still things we do not know about coral reefs.

Home made bee home.

 

 

This is a bee home I made for bee's to live in.

I put it near the raspberry bush so bees that pollinate the raspberry's see the bee home.

 

 

How I made the bee home was I took a can and rinsed it out. Then I cut a bunch of paper (That was going in the recycling ) into rectangles, rolled them up and taped them so they looked like a tube.

When I was finished that, I put all the paper tubes in the can and took an old shoe lace and tide the can to a tree near our raspberry bush.

And there you go a bee home. I found how to make one online.

I searched up "recycled bee home" and got this.
