Please answer the following four sentences to check in on your progress for the Newton's Law Investigation. 1. What is your hypothesis for your Newton's Laws project? 2. Do you predict that your collision will be elastic or inelastic? 3. What do you estimate the mass of each of your objects to be? 4. Which units will you use to show the speed of your object?
This week you are creating an investigation about Newton's Laws by creating a collision between two objects. 1. What are the two objects that you decided to collide ? 2. Which object will be still which will be moving? 3. How far apart will your objects be? 4. How will you make a record of your collision?
Aedin is planning on building a bungee jump tower in his backyard. He wants a ride that last for five seconds. The town says he may not build a tower more than 50 meters tall. Avery says the tower would need to more than 50 meters tall to get a five second ride. Macey disagrees saying the rate of fall is just 9.8 meters per second squared due to gravity. Therefore the tower would only need to be 49 meters tall. Who is correct Avery or Macey? Would Aedin be allowed to build his five second bungee jump?
Ryley was watching football and said to Gage "This game has a lot of examples of Newton's laws of motion. What parts of a foot ball game or other game might show newton's laws of motion.
Olivia wants to be an astronaut she was telling Contessa she really likes the powerful take off when the rocket lifts off from Earth. Olivia also said that you need rockets to land on the moon. Why would you need rockets to land on the moon?
Gabe was bragging to Mitchell that he could lift 200N of weight. Mitchell was impressed with how much Gabe could lift. Timmy said it was not that much weight because of the units that Gabe was using. Do you agree with Timmy and why?
We are about at the half way point of our study of motion and forces. Please post any thing that you might have learned that is new to you. If you have any questions or suggestion for our second part please post those as well.
Fred said to Sam that it would be really easy to move things in outer space because there is no gravity. Maddy and Joe overheard them talking and decided that Fred was wrong, because it would take force to move something in outer space. Who do you think is right and why?
Brian says to Carter that the heavier an object the faster it falls. Carter tells Brian he is wrong. Carter says the longer an object falls the faster it falls. Kadie says there are more factors involved when an object falls. Who do you think is right and why?
Matt and Liam were playing pass in the hallway. Matt said it was a good example of momentum. Liam said it was a good example of speed. Grace said it was a good example of both because speed is related to momentum. Who do you think was correct and why?
You roll a model car down the hallway. The car comes to a stop without hitting anything. Cameron says the car stops because there was no force pushing on it. Emma says it stopped because of unseen forces. Who do you agree with and explain why.
Two people leave from the same starting point and end at the same end point. One traveled twice as far as the other. Explain how this is possible using the terms of distance and displacement.
We have come to the point in the year when we launch into our study of physics. Let us start with a basic yet fascinating concept, gravity. What do you know about gravity? Not what the web knows but just what have you learned about gravity over the years.
There are two sides to the issue genetic engineering. What would be evidence to support each side. Please give one positive aspect of genetic engineering and one negative aspect of genetic engineering.
