Lab: I drew my scientist and introduce myself and my scientist to the class Intro some new rules of the course. The three questions help me think about the knowledges what we gonna learn next. Here are my answers: 1. It because the different positions between moon, sun and the earth 2. Because the sun move around the earth, make the different temperature at the different side of the earth. 3. The moon just in the middle of the moon and earth. We have the snowball represent the moon and a light bulb represent sun, then I know about  If the moon is exactly halfway between the earth and the sun, which they are all on the straight line in that situation, it will cause a solar eclipse, and if the moon is exactly blocked by the sun, and on the straight line as well in this situation, it will cause a lunar eclipse. with Lauren's help. Earth---------Moon----------Sun         Solar eclipse Moon--------Earth-----------Sun         lunar eclips...

 Lab： Talked about homework article first.  -Defined word assessment. -Think other more assessment not only quizzing assessment.  -Can support take photos sometimes or other things when the students have trouble about it. - Formative assessment      nobody get grades     don't mean a quiz  Energy Simulation -Collisions with air particles transfer energy from the rider to the surrounding air. -Pushing transfers energy back to the rider as they speed up. We ask to do to protect the egg, and use the material that provide. Challenge: Prevent an egg from breaking when dropped from a height of 1-meter  Constraint: Surface must be no thicker than your bowl  Testing: Record a slow-motion video of impact. Here is our short video from 1 meter high to drop down the egg, it survived. Then we did the second time, we dropped the egg from 2 meters high. It was cracked at the end. Here is the video what we did.   Why are both the surface and t...

 Lab: This week, we reviewed what is the Acceleration, velocity, and speed. And talked more about what is friction. Which mentioned on last week's lecture:  -Friction is a  force  that sliding across a surface -Magnitude depends upon:     1. Types of surfaces (stickiness, roughness)     2. How hard the surfaces are pushed together. Then we talked about how the force affect on the baby who is slay on the slide. What affects how long it takes a swing to go back and forth? -How hard you push -Pumping legs -Kicking off the ground -Body position -Initial angle of release -Weight of rider -Length of chain -Windy We did how does how hard or how soft you push affect the speed of the swing? in the group work. We gave the different push each time Soft push:  1. 10.40/ 10 swing                2. 9.49/10 swing Hard Push:  1. 7.10/ 10 swing                   2. 6.98/...

  Lab: This week we discuss the home work assignment article, Motivating three-Dimensional learning from student's questions, also talked about what affects a rider's speed down a slide, which is the big problem in this week.  -Rider weight -Slide material -Rider clothing -Initial push -Slide slope -Slide length -Turns on slide -Weather (snow, wet)  -Using a wat, etc -Waterslide    We use different materials to time the how many times we need slide to the different positions( 20m,15m,10m,5m) Then we got the claim is smoother the material, the faster the rider will go. Change of the material , the change of speed rider will go. Lecture ：We talked about why will the speed of a rider on tall slide be higher than on a shorter slide?  It will be increased. Move very quickly at the beginning, and very slow at the end. Acceleration=change in velocity /time Why does height matter? -Riders acceleration as they slide down a slide -The higher the slide, the more tim...

Lab: First of all, we talked about syllabus of the class this semesters and how the quiz going. Then we talked about why should elementary students learn about science? And Kids in races with different speeds which is a big question in this week. We do the race between me and another person to walk and "run" in 6 meters and 10 meters, then record the time to compare with each other. To see what speed it is. The race between with the other group in the whole class. Lecture: We talked about Motion, We check on NGSS PE 3-PS2-2 to see where did we do the SEPs, What DCI ideas did you need, and How did you use CCCs. And learned How to measure the motion by: Speed=Distance/time Here are some  Key Takeaways from the class:  Kids should explore describe and predict motion by:  • Designing investigations to collect data about motion  • Identify and describe patterns in data  • Measure key characteristics of motion like position and speed  • In order to communicate c...
