4th Grade Science Class 1/28/20

This afternoon, the students completed the activity in the notebook we started yesterday. Then, we discussed where each fossil fuel comes from and how they are used. 
 
The students completed a foldable about the fossil fuels in their books. They were to write one sentence about each type of fossil fuel. I will check this for points tomorrow. 
 
After, we read about how energy changes on page 97. 
 
**There will be a quiz on Lesson 1: Energy from Nonrenewable Resources on Friday, February 7th. It will cover pages 90-104 in the Unit 2 book. Because this is a quiz, there will be no formal review; however, I will post a "focus on" guide later this week.

4th Grade Science Class 1/27/20

This afternoon, we watched a video about natural resources and then read and highlighted details about nonrenewable resources. We talked about fossils fuels, where they can be found, and how they are used. 
 
We looked at a diagram that showed how coal is transformed into energy. We also began looking at a powerpoint that showed the sequence of how coal goes from the mine to becoming electricity in the home. We will continue with this tomorrow. (pages 94-95)

4th Grade Science Class 1/24/20

I am so happy to be back.  I really missed all my students. 
 
This afternoon in science class, we completed the inquiry activity on pages 92 and 93 together. 
 
Then, we watched a video about natural resources.  

Thursday December 12th Class Recap and Review

On Thursday, December 12th we will review these concepts through practice questions on the board. I have written it on Microsoft Word for anyone who wants to review it for our assessment on Friday (especially those students who have trouble taking notes quickly). These are the same concepts we have been working with since the end of last week.  Topics related to electricity are very abstract for 4th graders so we connected to real-life circuits, illustrations, and videos since we started the topic last week. I recommend that you continue to watch videos for kids related to each topic if you are fully understanding the concept.

Important Concepts :
Energy can be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light.

The currents may have been produced to begin with by transforming ethe nergy of motion into electrical energy.

4th Grade Science and Social Studies Classes 10/4/19

We worked on a team building activity and our rollercoasters. 

Important!

Students should have both their Unit 1 and Unit 2 science books in class tomorrow. We will be transitioning to Unit 2 soon! 

4th Grade Science Class 9/30/19

This afternoon, the students were given their day to present the science fair project. Then, we wrote the procedure for the module project on page 65. Finally, students worked on their review handout that will be collected for points tomorrow. 

4th Grade Science Class 9/27/19

This morning, we read the STEM career connection on page 56. Then, we completed the lesson review on pages 58-60. We wrote: 
 
Summarize It 

Contact forces transfer energy of motion from one car to another, resulting in the change of motion, and also possible damage of the cars. The energy is conserved. Some of it is transformed into heat and sound. 

1.The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred. In a collision, kinetic energy is transferred between the objects and transformed into heat and sound. 

2. B

3.Since the bowling ball has momentum (kinetic energy), it would transfer its energy to the pin and knock it over. 

Extend It

Seat belts keep people safe from being thrown out of a car as a result of momentum. They decrease the force by stretching. 

Then, we completed the lesson planning on page 62. 

Some problems I need to consider is how much energy of motion I will need to make the balls collide. If there is not enough energy, the first steel ball might not make it to the second one. The potential energy and energy of motion can change throughout the coaster depending on how many hills I use. 

Finally, we ended the lesson by revisiting the probe and evaluating. 

4th Grade Science Class 9/26/19

This afternoon, revisited the toy car crashes on page 53 and wrote: 
I know that energy was transferred because the motion of both cars changed when they collided. The moving car slowed down and came to a stop while the car at rest started moving. The energy of motion of the moving car was transferred to the car at rest. The most energy was transferred when the moving car has the most speed. 
 
Next, we completed the Newton's Cradle investigation on pages 54-55.
 
5. Some energy is transformed into sound and heat each time the balls collide. The energy is also transferred through the balls to the last one.
 
6. The kinetic energy transfers through all of the balls when they collide. As the ball falls, potential energy is transformed into kinetic energy. As it rises, kinetic energy is transformed back to potential energy. 
 
Finally, we read and discussed the primary source document on page 56. 
 

Highway designers design guardrails to "absorb" kinetic energy of a moving car. The energy of the moving car is transformed into other types of energy (sound and heat) so the moving car comes to a stop safely. 

4th Grade Science Exam 2 Review

Here is the exam review for exam 2. Please understand that this is uploaded extremely early and because of that, we are still covering material that is on it. Students are welcome to begin the review as it is important to begin studying as early as possible; however, we will not be going over the review in class until Tuesday, October 1st, a week before the exam.
