Asking Questions: Asking questions is where we discuss what we are looking for in our scientific practices, asking what, when, where, why, how and who. When asking questions we try to determine things like, what are we trying to accomplish? Why are we carrying out this scientific inquiry? How are we going to proceed? Who, the history of important people related to the scientific inquiry.
To prove the 1st law, you can see that the air released from the balloon disturbs the state of rest of the car and makes it move. To prove the 2nd law, you need the exact measurements, so I can't help you. To prove the 3rd law, you can see that as the air in the balloon is
B. The scientific Method 1. Testable Hypothesis- a testable prediction, often implied by a theory. 2. Operational Definition- a statement of the procedures (operations) used to define research variables.
Van de Graaf Generator Activities Activity 1: Explain that the globe of the generator builds up excess electrons through conduction. The built electrons are repelling since they are like charges and we know that like charges repel so they are spread out as much as possible. The charges are spread out because the globe is a conductor, unlike electrons that are rubbed onto the balloon, which stay in the general area where you rub the balloon. Activity 2: The electrons are in an excited state because of mutual repulsion, which means that they are looking for a place to go where the electron population is not so dense. Since the electrons are excited they will jump to anything that comes close to the generator globe, such as your hand, the desk,
law describes, theory explains * What is the difference between a scientific theory and a scientific hypothesis? theory is well tested, hypothesis is an educated guess * How are scientific theories, laws, and hypotheses similar? they all start with a hypothesis, kind of a step by step analysis * Why is evidence important in science? to support or refute a hypothesis * What happens if scientists discover new evidence that contradicts an accepted scientific hypothesis, theory, or law? it leads to modification of scientific
Liana Ortiz December 12, 2012 Balloon War In this project I will determine the effect on the rate of reaction. The rate of most chemical reactions will increase in higher temperatures, however this is not true for many other chemicals. The best temperature for each chemical reaction needs to be researched. Excess heat in many cases can lower the rate of reaction or even reverse the reaction. In some other cases excess heat may result in a different product other than what is expected.
What did Boyle’s experiments convince him about cold? That heat is a form of motion of a particular kind as bodies cool down the particles move less and less 5. How did Boyle explain that substances expand when they warm up? He thought back to his air experiments, and explained that the particles have spring like coils that expand as they heat 6. Describe the earliest alcohol thermometers.
1. Form hypothesis: In this experiment, you will pile weights on the lid of the container of gas. What do you think will happen as more weight is added to the lid? 2. Notice: Look at the DESCRIPTION pane.
2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this. Accept/reject
(additional game, spot the pop culture references) A Wild late star project appears! Pt.1 Project uses explain, depending on how this is written it may be super effective! A star begins its life as a swirling mass of gas known as a nebula. Because of the gases weight, the nebula pulls the gases towards one point or several based on the size of the nebula. The idea could be considered as madness but others may say THIS IS PHYICS!
