Laws of Conservation of Matter and of Energy

The Iced Tea Debate The Salty Soup The Fire Bug 2 Use the DATA chart provided for recording observation based on three demonstrations you will watch 3 Watch each part of the experimental demonstration and make predictions about what will happen in each scenario . Record your predictions and observations in the Data an Observations section of your laboratory report format. Problem: How can matter and energy be described in parity of systems? Analysis : Use your data table to identify the physical and chemical changes observed in the demonstrations as follows.

Analysis Use your data table above to identify the physical and chemical changes observed in the demonstrations as follows: 1. Complete Data Chart above filling in Scientific Methods for each demonstration. 2. Use the drop-down menu options to record any physical and/or chemical changes observed. 3. Once you completed the data chart, complete pre-made paragraphs below by writing an analysis that includes details on how the Law of Conservation of Matter and the Law of Conservation of Energy are supported by the experimental ministrations.

Use the following reflection questions to guide you in writing the analysis: Was matter or energy lost or destroyed in any of the scenarios? Did your predictions match the second portion of the demonstrations? What phase changes did you observe? What kinds of energy were input and output in each of the scenarios? Paragraph 1 – How the Law of Conservation of Matter is supported by the experimental demonstrations: In the law of conservation particles and materials are neither created nor destroyed . It was similar towards the experimental demonstrations because nothing changed or destroyed in the processes .

Kinetic and potential energy was used in the experiments. Paragraph 2 – How the Law of Conservation of Energy is supported by the experimental demonstrations: Experiments do not consommé the energy but conserve by changing them from one form to the other . This allows all energy to remain constant so for each experiment different form occurred but never changed the element of the experiment Fourth Scenario Describe a fourth scenario in which either the “Law of Conservation of Matter” or he “Law of Conservation of Energy” could be observed.

Using as many sentences as needed, describe how an experiment could be set up to further explore your recorded observation. The goal is to show understanding of the concepts in the lesson. Choose law of Conservation of Energy Suppose a Hard mini ball is placed in an automatic air power sealed container will notice that no matter how much you will leave the ball bunching the ball will never stop bouncing. That happens because the ball develops both potential and kinetic energy,the sum of those two give us the canonical energy which remains constant.

Scientific Method The Predictions?What do you think will happen? Well the ice tea should freeze and it will have kept its same chemicals thinker soup would have got salty from the Heat extracting the salt from the spices and making it expand from liquid water The more heat took in to the body caused more moisture and bugs to come. The less heat from the further away from the fire. Observations?What did you see happening in each demonstration? Nothing was affected from O degrees and 20 degrees

They measured the water displaced from soup into the original amount It Explained the Heat and inner and outer reasons for bugs and body temperature hot and cold from front or back Conclusion?What was demonstrated here? They froze the ice to see if a change would occur in the original compound chemical bonds From the measurements of the original they found out the amount of water boiled out from heat the salt stayed in and made the entire soup salty.
