charlie’s law


 these previous weeks we have been learning about Charlie’s law. Charlie’s law is about temperature and how they can increase or decrease gas. In one of our labs, we had a beaker full of colored water and a balloon attached to the top. Then we placed a beaker into a bowl of hot water. The hot water raised the temperature in the water in the beacon and the gas will be more dense and rise, because as heat rises, the gas will move up to the balloon and blow it up. Once you get a big balloon you place the balloon into the snow and the gas will slow down the density of the gas and the temperature will lower. Even though it is slowing down, you can still place the beacon into the hot water and slowly rise again. The gas density goes up and the water starts to warm up again.



We see Charlie’s law in hot air balloons. Hot air balloons are a closed system with a flame in the middle, the flame heats the air and then hot air rises. The balloon will rise and go up. You can overheat the balloon but it really never happens in professional hot air balloons. How I can use Charlie’s law is when my family has our fireplace on, we need the fan on so that the heat doesn’t escape the house or room. When we did the Charlie’s law lab, what satisfied me was when the heat decreased and the balloon decreased as well. It really made me understand Charles’s law. Charles’s law is a complicated and brilliant and it is a big part of how we can keep warm and cold.  


 How did he find out the law?

Was he the first one to experiment with heat, cold and rising air?

When did the law get placed?

exothermic and endothermic!

This week  we have been learning exothermic and endothermic .One experience we did this week that helped me understand exothermic and endothermic, was your ice cream lab. In this lab, we used plastic bags, measuring cups, rock salt, and snow.  The snow and the salt react to each other and the snow turns to ice. How this happens is when you shake the ice and snow it makes the snow melt then freeze over because of all the coldness from the snow. That would be  considered an exothermic reaction, but if you didn’t have enough salt the reaction will be slower and it may not turn the snow into an exothermic reaction. That reaction will also is a endothermic reaction, because after it gets so cold it turns into ice and makes the surrounding cold as well. That is why we wore gloves to protect use from the cold exothermic and endothermic reaction that happens.

These reactions really are in everyday life and everything that is cold and warm. Like when we use hand warmer or frighes. The freight keep the cold which would mean that the freight is endothermic . The hand warmer is placing warmth into your hand and that is exothermic.what was satisfying about the lab was how it made so much sense and gave me an understanding of the exothermic and endothermic and it was really yummy! This was one of my favorite tests and the most interesting one for me. Now I really understand exothermic and endothermic.


If there is an exothermic reaction turning the water into the ice ,making it solid, would that be a change of state?


 If you have a fever and you feel chilly, but really you have a fever would that be exothermic or endothermic?

When you put heat into your house where is the cold going?  

Physical and chemical change 1/31/21

In the previous weeks we have been learning about how to be a forensic scientist. Mrs. shane  set up a whole murder, and we did really cool test that used the laws of physics. One that was so much fun was when we used a a flame and different pieces of fibers from the murder scene and test what would happen to them when they hit the flame. The first step was to place the fiber near the flame. If the fiber got flammable, that meant it had a chemical property. Then you place the fiber into the flame, if it changes colors or state that means it probably has a physical property, but if it completely dissolves that means it is a chemical property.The second step is to get the residue and find out the different smells they have. Even though that seems like something you could pass up or forget to do, it actually is a really important step because it can  make a difference in how you identify the fiber. After you do the first test, you move onto the second test which uses microscopes and the samples of the fibers. You put the fiber onto a microscope and see every little fiber in it.

This test really was fun and helped me understand physical and chemical properties. It also really made me think about how everyday things use physical and chemical properties. Like how scientists use chemical properties to find the differences in the substance. How I will use chemical and physical properties is by baking or making art. One thing that was a fun fact I found out was when you put a chemical on blood, the chemical will turn the blood pink. It made me think about blood physical properties, which really was interesting. I loved the test we have been doing because it is a really good way to find chemical and physical properties. 


What chemical  is the one that changes blood into a pink color?


Can you ever change something from turning into malleability ?


You find the properties without doing experiment?

physics! 1/10

In class we are learning about physics. To learn, we did a lab and used a graduated cylinder, marbles and a sink clog. We used the graduated cylinder to measure the objects by placing it into the water. The height of the water would rise, and the measure would change. It would change because the density of the last number we had was we would subtract it . Then we took the object out of the graduated cylinder and measured it on a scale for the mass. Another lab we did that really helped me make sense of physics, was when we measured blokes and used the method length x width x height. That was one of my favorite methods.

 I learned that physics is a way of doing measurement in a different way. Like how you can measure mass by placing it on a scale to find density by placing an object  in water and finding the measurement of the object. It surprised me how much scientists use physics to find everyday objects that they cannot measure. The most thrilling part of physics is when you get to the part where you find the numbers but they have to be changed to density or when you have density and volume and need to find the mass. I feel more confident because I understand physics more. The labs we did this week were really fun and helped to make sense of physics.


Who was the first to teach physics?

How do you find mass if you have on scale?

What does the word  physic mean?



termites! 12/13/20

In class, we have been learning about Biomes and their climates and adaptations. Morley and I have been studying Botswana and its climate. We are building a website about Botswana and making a diorama. I have been writing specifically about termites. Termites are a big population in Botswana and every Savanna in Africa. The scientific name for termites is Isoptera and their classification is phylum Arthropoda. Termite colonies last 50 years, and they mostly eat mold, decaying wood, and grass, all which are organic matter. There are 2700 termites species that are known in science. Termites have an extremely complex system in the mound they live in. The system consists of a queen who supplies new termites and helps keep the mound safe. The queen can lay thousands of eggs and live for 45 years. As the queen becomes more pregnant, the worker termites take the babies to a nursery. The construction of the mound is mostly made out of dung, soil mixture, and termite saliva. The inside of the mound has holes that let in fresh air.

Termites are helpers in Botswana. Termites are decomposers and help the flora and fauna grow. Termites share many features with insects in general. Termites have a dark head with no waist between the thorax and abdomen. The non-queen termites have thin skin, never develop wings, and are blind.These attributes make them very vulnerable and major prey to insects. Their predators are shrews, aardvarks, and ants. The top of the mounds consists of a chimney that has an inner passage that a connected to the nest part of the mound. This chimney also is a helpful way of keeping the air perfectly temperate and ventilated. In the main nest part, there is a cultivated fungus that the termites grow themselves. On the outer base, they have tunnels that travel to the outside and also into the mound.  Termites have unique jaws that saw and grinds up wood and hard matter. The limiting factor of termites is climate change and humidity. That will make less plant growth, and the termites will eventually die off.

how many can live in a mound?

how old can they get?

12/3/ 2020 Giraffes forever.

Giraffa camelopardalis reticulata, which is most commonly named giraffes, are one of the many amazing animals in savanna. Giraffes have long legs that  are very graceful. The biggest chartictic is that they are 6 foot tall and have 7 neck bones.. They also have long eyelashes that protect them from needles on branches. Every Giraffe has a different pattern. It is so entertaining to watch them, because they are like a different  fingerprint. Giraffes also have horns called ossicones. All sexes of giraffes have them.In the savanna the giraffes move a lot. They don’t have a exact place because, the do not have behavioral problems and get very well with each other. Giraffe’s home land can be between 50 to 8 square miles. I t is normal for them, because they can eat most everything. Giraffe’s love the hot sun in the savanna. They also live in open spaces so they can flee from predators.Giraffes Are herbivores they mostly eat from acacia trees and will eat most of the shoots and the leaves.  Cows, which are baby giraffes, eat mostly low fiber food until it is grown.

Giraffes are very important to the ecosystem. Their niche is to eat the leaves and let the tree grow. They also help other animal,because when they eat the leaves, it warns them of predators and their surroundings.They are considered prey because they are very vulnerable and animals like lions, hyenas eat them.they get kill from predators a lot, and the cows will be the biggest one to be killed. Giraffes  Abduction is that they have thick strong tissue  that protects them from needles that are on the branches and  it has long eyelashes to protect them from the thorns. They also have long legs that make it really hard to drink water but, they have adapted this way of drinking by pulling front legs and drinking from there.Some really cool facts about giraffes, is they do not have not just a walk but a galop. The pace starts with the front huffs moving together ,the back ones will push off and the motion will go right into the gallope. They will also tilt their head  to maintain balance. Giraffes gestation time will be up to 15 months , they will have their cows in the drought seasons and they will weigh 220 pounds and are 6 feet tall. Giraffes were painted on tomes that were painted by Egyptations .  Another awesome thing is that  when the cow is first born the mother will have mother and baby time. In this time the mom will quarantine the cow and learn it’s sent, after that the mother will go back to the group and the baby will follow another baby and will make a  daycare,and when the cow is hurt the mother will step over the cow and then she will kick the predator till it baby is protected.


manatees and dugongs ! 11/15

Marvelous Manatees

Manatees are lovely and sweet animals. Manatees love fresh water, and they live close to rivers and streams that have vegetation. Manatees are herbivores that have teeth that get so ground down that they have to drop the old and grow new ones. This helps them so much. Manatees are a minority species in the United States. The scientific name for them is Trichecus and are in the porpoise family. They have always been gentle and loving to each other. How babies find their mother is by their whiskers and the vibration signaling from their mother’s whiskers.

Memory is very very important for every animal. Manatees are amazing and graceful, but can be dangerous. Manatees can stay underwater for 20 minutes and swim up to 20 miles an hour. With being underwater, they use lots of energy.  They can swim because of the platypus tail. Manatees are endangered from boaters. Some manatees lose the mothers from boaters. Manatees sometimes eat trash or fish hooks that can kill the them.


Dugongs are animals that are related to the m

    Manatees spend most of their time in saltwater more than freshwater. Dugongs are have more of porpoise’s tale then a platypus’ tale. Dugongs love to be in warmer water and like to live in East Africa and Australia. They eat also vegetation, but can spend less time in the water. The dugongs are mammals and have live birth too. They are endangered for the same reason as the manatees. They are also poached. How come the dugongs have more a cup like  mouth? Why do  manatees eat plants ? How can I help?

Why we need to stop poaching! 11/8

Poaching – A Terrible Practice

The topic of poaching is one we all learn about,  but do we really think about it? Well, why should we? I mean, do we go home and think of all the beautiful lions that have died from poachers?  Poachers kill and take keratin from this animals just to sell it to the black market. There are many endangered animals in Africa including elephants, lions, rhinos, and many more!

In Africa 100,000 elephants are killed just for their ivory each year. Many elephants are hurt, but the sad thing for elephants is when an ancestor dies, the elephant will know it, and put its trunk on the bones of its family members. Rhinos are also slaughtered and plundered. I769 rhinos have died from poaching this year. The effects of poachers on the environment is catastrophic.

National Parks in Africa have made foundations and laws to stop the poaching. They also have infrared cameras that track and see the animals.The penalty is monetary fees and prison. Poaching happens all over the world.  For instance, Asia has almost the same amount of poaching as Africa. There are also animals that have become endangered because of poaching.

Why are poachers so violent?

What are poachers thinking when they hurt endangered animals?

How can I help!?

What is red, white, and black, and has fur all over, and is cuter then ever!?

Red pandas, most commonly named Ailurus Fulgens, are so cute! Red pandas are related to the pandas and raccoons, but most people  think they are mostly related to pandas. They also their own group Ailuridee! Red pandas are mammals that sleep most of the day . They are herbivores, and they mostly eat bamboo, roots, and fruits! Red pandas coats are a dusty red with black and white! Their coats are actually for camouflage when they’re up in the trees they are hidden from predators because of the shade of the tree. Red pandas actually have lots adaptations that help them in the wild.  Their greatest one is that their eyes have tear marks that travel to the mouth to protect it eyes from the sun! Another adaptation is its tale. They can protect themselves from the winters by curling up! Their fur is dense, so it is winterproof.




Red pandas live in China, Nepal, and North Myanmar. Red pandas use scent markings to  keep their territories. They use urine and anal glands. the most exiting  thing is that they have markings on their foot pads. The clear liquid is not scented to most humans but most predators can. They test it by using its thick backside of its tongue that takes its glands. Red pandas have something that there ancestors do not have. They are very flexible, and they have thumbs! Their ankles are so flexible. They are even able to climb down head first. Red pandas are not very social. When they are mating they are the most social. Most female Red pandas have four babies. They are born in the summer and the spring. They are taken care of by their mother for ninety days, and will not leave the nest. Even though Red pandas are not the most common endangered animals, but they are a big minority. Red pandas are dealing with  deforestation and and the poaching for their fur! How is this fair? Why are humans not thinking of them? Why do most pandas live in China? How do we help them even though we don’t live near them?



There’s a fungus among us!  10/11


In class we have been learning about mushrooms. We explored the woods and looked for different types of fungi. We drew them in our notebooks and asked three questions about each type of species and the decomposers surrounding it. I really enjoyed getting to draw the mushrooms!


My favorite part of this learning experience was that we got to be one with nature. We also made spore prints that were really cool. One thing I learned about mushrooms is that what we see is the fruiting body. Mushrooms spread by microscopic spores that spreads across the ground. Mushrooms can grow really fast. Many mushrooms are edible but some are not. You have to be careful to identify edible mushrooms correctly!
