Our claim that bouncing bubbles is a physical reaction because there was a mixture where no new substance is created, but there is 2 or more compounds making up the mixture. There is no new state of matter, no new color, nor a new smell, did change temperature based on average of all, didn’t produce gas, and didn’t produce light. Also the experiment did not create a gas or produce light. When we put the 10 ml of Dawn dish soap, 30 ml of water, and 1 ml of Glycerine together many things changed that were physical because it is a mixture not a chemical change so our claim is true. The volume is 41 ml so didn’t react to form a new substance or add any volume when mixed them together except for the bubbles when stirred they were created but that can happen without mixing if you have ever washed hands you produce bubbles when you touch the water because the soap reacts with the water to make bubbles which is a physical change because it is just a mixture didn’t change anything really.The smell did not change because the Glycerin and water did not a have a smell while the dish soap did making the mixture smell like that. There was never any sound. Touch was different when mixing them because none of them were sticky and it ended up being sticky because of soap and glycerin mixing. The taste was soapy we could taste the water , not the glycerin because not safe, and the soap tasted like soap. This is because when you add glycerin it makes it stronger it doesn’t make anything new it makes it stronger because when add glycerin makes it thicker. What happens is when you touch it with the glove you can bounce it because a bubble’s worst enemies are oil, dirt, evaporation, and gravity. The bubble will bounce off of a surface if the surface is free of oil or dirt particles that would normally cause a break in the thin soap film of the
Dropper Poppers are rubber toys that resemble half a rubber ball and are shaped as hemispheres. They are turned upside-down (or inside-out), left on a flat surface, and after approximately 5 seconds, the dropper popper flies upwards, going higher than its original position. Simply put, the rubber needs to return to its original position, and creates a high surface tension. The rubber’s urge to return to its original position also causes instability within the structure of the dropper popper. When you drop the toy onto a flat surface, the inverted part pops back out, slams into the surface, and causes the toy to bounce into the air. This is a very basic explanation of what causes the dropper popper to act the way it does, and the physics principles
For this experiment we have to use physical methods to separate the reaction mixture from the liquid. The physical methods that were used are filtration and evaporation. Filtration is the separation of a solid from a liquid by passing the liquid through a porous material, such as filter paper. Evaporation is when you place the residue and the damp filter paper into a drying oven to draw moisture from it by heating it and leaving only the dry solid portion behind (Lab Guide pg. 33.).
A: The reaction with water and vinegar was the most useful in this experiment. The physical properties were very self explanatory because the texture of the powders was all different expect icing sugar and cornstarch. Also the Ph levels were very similar of six and seven for corn starch and icing sugar respectively. d) Q: How confident do you feel about your identification of the
The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.
The purpose of the experiment was to find which balanced chemical equation best represents the thermal decomposition of sodium bicarbonate, or baking soda (NaHCO3). The lab presented us with four possible equations but there was no way of determining which equation was correct unless we performed an experiment and using the law of conservation of mass which says that mass is conserved during a chemical reaction, the law of definite proportions which says that a compound is always made of the same proportion of elements by mass, and stoichiometry to properly balance the equation.
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.

Bouncing Ball Investigation Aims: In This experiment, I'm going to discover how the surface affects the height that a of a tennis ball Introduction: All green plants are able to use light as a source of energy. Chlorophyll (green coloured pigment in leaves) absorbs light and changes it into chemical energy, which is used to power all the chemical reactions that go on in a plant cell. This is called photosynthesis. Photosynthesis is the process of producing glucose from sunlight, which takes place in the leaves.

Investigating the Bounce of a Squash Ball This investigation is associated with the bounce of a squash ball. I will be investigating 4 different types of squash balls, which have different, bounce properties and compare them to each other and relate them to why each different type of squash ball is used. The relationship will be associated with how different balls are used at different levels of proficiency in the game of squash i.e. the squash balls that don't bounce much will probably used at a less proficient level whereas the balls with the most bounce will be used at professional level. The different coloured squash balls I will be using are; white, yellow, red and blue, and I will be finding out what the difference is between them.
How does the material of a ball affect the bounce height/vertical motion of that ball?
What does happen when you mix vinegar and baking soda? While your immediate answer may be "it fizzes and turns white" there is much science behind the concept. You will find that what it "looks like" is not nearly everything behind what really happens. Baking soda and vinegar form a completely different compound (when two or more elements combine; broken down by chemical changes like adding energy as heat or an electric current), which has it’s own properties. From the particle model of matter to the way that a chemical reaction is represented in an equation, the answer is definitely complicated.
Is it ethical or even helpful to try to impose order on a haphazard existence? Is it right to play God, to steal the limelight from the cosmos? Man used to ponder existence, but with the increasing possibilities of science, we now ponder our power over existence. In “An Experiment with an Air Pump,” Shelagh Stephenson uses symbolism associated with Isobel as a voice of foreboding in a society “enraptured by the possibilities of science” (3). Stephenson associates Isobel with a bird, a pile of bones, and a sheep to reveal the dark side of the “light,” the scientific revolution.
I dedicated my pep talk to to people who have impacted my life in a good way. These to people have been a part on my life from the beginning. My mom’s dad, aka. Pop-Pop is the first person I wanted to dedicate my speech to. Then I thought and I remembered my brother. My brother Owen has been a part of me since I was born. To start off I’d like to talk about my Pop-Pop. My Pop-Pop was a very humble man, and a friend to pretty much every person in the entire world. He would be that guy who made friends with the waiter. He was a lovable man with a strong love for his family. He was a kind hearted man who never showed a sign of hate, unless the eagles lost. Then he would get mad at the opposing team. My pop-pop has shown me that no matter who or what brings who down, there is another ladder to climb. He always told me that I had the best hugs, so I went around giving everyone hugs! If he had a bad
