0:11 - 0:13I have here an empty glass
-
0:13 - 0:17standing directly
in front of a blue and white paper. -
0:17 - 0:22If I fill it with water, what do you think
will happen to the colors? -
0:22 - 0:26Will they remain the same
or will they appear different? -
0:26 - 0:28Let's check what you think.
-
0:28 - 0:31Who thinks that the colors
will remain the same? -
0:31 - 0:35Who thinks that the colors
will appear different? -
0:37 - 0:39OK. Most of you are right.
-
0:42 - 0:46Something will happen, but what?
-
0:46 - 0:48Let's try it.
-
0:56 - 1:02This is one example of how I teach physics
in my class, in this case, optics. -
1:02 - 1:05I ask questions, I make students think,
-
1:05 - 1:07predict, talk to each other and explain,
-
1:07 - 1:10I encourage and inspire curiosity,
-
1:10 - 1:14and they learn
through demonstrating an activity. -
1:15 - 1:19Many students think that learning physics
is like climbing a cliff, -
1:19 - 1:21hard, frustrating, and endless.
-
1:21 - 1:23(Laughter)
-
1:23 - 1:25Some of them get stuck in the middle
-
1:25 - 1:30and when they give up, they convert
their potential energy to kinetic energy. -
1:30 - 1:31(Laughter)
-
1:31 - 1:35Physics doesn't have
to be scary or difficult. -
1:35 - 1:38Physics doesn't have
to be boring or tiring. -
1:38 - 1:41I see physics like a huge amusement park.
-
1:41 - 1:45I enjoy physics. I love physics.
I love to teach physics. -
1:45 - 1:48So, I want my students
to feel the same vibe. -
1:48 - 1:51We can teach physics in a variety
of methods so that students -
1:51 - 1:57will have a deeper understanding
and have fun while they are learning it. -
1:57 - 2:00My name is Kobi, Kobi Shvarzbord,
-
2:00 - 2:03and I have been a physics teacher
for the past 16 years. -
2:03 - 2:09At my school, 25%
of the students study physics. -
2:09 - 2:14This is 300% higher
than the national average. -
2:14 - 2:18I have classes
in which almost 50% are girls. -
2:18 - 2:20This is because I believe
-
2:20 - 2:24that teaching physics
should be exciting and fun. -
2:24 - 2:29The focus of teaching and learning
is on what is actually being taught; -
2:29 - 2:31not on the student
and not on the teacher, -
2:31 - 2:34they are engaged in the activities.
-
2:34 - 2:36I am always in contact
with other teachers, -
2:36 - 2:40sharing ideas about physics education.
-
2:43 - 2:46And school is not just my workplace.
-
2:46 - 2:49To be in class and to teach is my love,
-
2:49 - 2:53my fun, my challenge,
my adventure, my inspiration. -
2:53 - 2:57So, I would like to invite you
to take a peek in my classroom, -
2:57 - 3:00to my amusement park, Physics Land.
-
3:00 - 3:03We will begin right now.
-
3:04 - 3:09Let's solve a problem just like I remember
from learning physics. -
3:09 - 3:12Given the initial velocity of a ball
-
3:12 - 3:15and the horizontal distance
from the launching point, -
3:15 - 3:18what is the height
above the launching level -
3:18 - 3:20that the ball
will pass through in its motion? -
3:24 - 3:27We can draw the ball.
Here is the initial velocity. -
3:27 - 3:32We put the x, y coordinates
and we write an equation. -
3:32 - 3:37The x component of the position
is the initial velocity, -
3:37 - 3:41multiplied by cos(theta),
multiplied by time. -
3:42 - 3:47Wait a minute, I just said
we can do it differently. -
3:48 - 3:52My students get the same task
but they really do it. -
3:52 - 3:55They calculate for different distances
-
3:55 - 3:58what height is
-
3:58 - 4:01that the ball will pass
through in its motion, -
4:01 - 4:04and they need to attach
a small ring at that point. -
4:04 - 4:07This is a team effort.
They take it very seriously. -
4:07 - 4:10After we finish attaching all the rings
-
4:10 - 4:14we launch the ball, cross our fingers.
-
4:14 - 4:17Eight rings. One ball.
-
4:17 - 4:21Will it pass through all of them?
You've got to see it. -
4:25 - 4:26(Cheers)
-
4:29 - 4:31(Applause)
-
4:33 - 4:37The response of the students is amazing.
-
4:37 - 4:41See how excited students
can get with physics! -
4:42 - 4:45And they never forget to add
a selfie to our Facebook group. -
4:45 - 4:46(Laughter)
-
4:48 - 4:51Is there any kid
who doesn't like candies? -
4:51 - 4:54What about gummy bears?
-
4:54 - 4:57Why not to use gummy bears in physics?
-
4:57 - 5:00Like - making waves.
-
5:00 - 5:04My students built a simple wave machine
with gummy bears. -
5:04 - 5:08Yep, you heard right. Gummy bears.
You've got to see it. -
5:09 - 5:12I need two volunteers please
to come and help me. -
5:12 - 5:14Thank you,
-
5:14 - 5:15thank you.
-
5:21 - 5:25Come, you hold this side,
and you can hold this side. -
5:30 - 5:33This is the difference I was looking for.
-
5:33 - 5:35This is an exciting activity,
-
5:35 - 5:37but at the same time,
-
5:37 - 5:41it deals with the basic concept
of mechanic waves -
5:41 - 5:45and the common misconception
that students have about this topic. -
5:45 - 5:49They actually measure
the speed of the wave -
5:49 - 5:51and arrive to the conclusion
-
5:51 - 5:55that it depends on
the matter's properties only. -
5:55 - 5:58They see that the wave moves
-
5:58 - 6:01but the gummy bears stay
in the same position. -
6:01 - 6:05One of the main misconceptions
that students have. -
6:05 - 6:06Thank you for helping me.
-
6:06 - 6:08(Applause)
-
6:12 - 6:14After we finish the activity,
-
6:14 - 6:17and to be honest,
even during the experiment -
6:17 - 6:19they eat the gummy bears
-
6:19 - 6:20(Laughter)
-
6:20 - 6:24so they realize that physics
can be also tasty and sweet. -
6:24 - 6:29And I won't even talk about
radioactive decay activity with M&M's. -
6:30 - 6:34As you can see food has a warm place
in my class and in my heart. -
6:34 - 6:35(Laughter)
-
6:37 - 6:42Just before we finish our journey
I want to take you far away. -
6:43 - 6:47I want to take you
to the particle accelerator at CERN, -
6:47 - 6:51near the border of France and Switzerland,
-
6:51 - 6:55a visit to the cutting edge
of physics research. -
6:56 - 7:00After I participated
in a high school teachers program at CERN, -
7:00 - 7:04for three weeks, with teachers
from all over the world, -
7:04 - 7:08I brought particle physics
into my classroom. -
7:08 - 7:11My students built a particle detector.
-
7:11 - 7:14They could actually see the interaction
-
7:14 - 7:18between particles from cosmic rays
and the detector. -
7:18 - 7:22They even play cards to understand
the Standard Model, -
7:22 - 7:25the basic building blocks of matter.
-
7:25 - 7:31This activity was created by a group
of teachers from different countries. -
7:33 - 7:37But most exciting,
I take my students to visit CERN. -
7:37 - 7:42There, they can see the largest
and the most complex instrument -
7:42 - 7:45that was ever built by humankind.
-
7:45 - 7:50At CERN they actually can see
how physics research is conducted, -
7:50 - 7:56and they face the main questions
that physicists look for today. -
7:56 - 8:00Why there is far more matter
than anti-matter in the Universe? -
8:00 - 8:02What is dark matter?
-
8:02 - 8:06What is beyond the Standard Model?
Supersymmetry maybe? -
8:06 - 8:12They realize that we don't know everything
and we don't understand everything. -
8:12 - 8:18But most powerful for them [is the fact]
that they understand that perhaps, -
8:18 - 8:22they are the future scientists
that may discover -
8:22 - 8:25the answer for those questions.
-
8:25 - 8:28And if you can't bring
your students to CERN, -
8:28 - 8:30bring CERN to your students.
-
8:30 - 8:34Set up a virtual visit
or a video conference. -
8:34 - 8:37I didn't start teaching like this.
-
8:37 - 8:40Only after I'd been
a teacher for several years, -
8:40 - 8:43I was looking to do something else.
-
8:43 - 8:46I wanted to do it differently
for my students. -
8:46 - 8:51I want to do it more tangible,
more exciting, more significant to them. -
8:51 - 8:55I want them to learn better,
to understand better, -
8:55 - 8:59and have fun and enjoy themselves
at the same time. -
8:59 - 9:03I didn't create all of these activities.
I researched and had help. -
9:03 - 9:06Teachers, you just need to want to find
-
9:06 - 9:10some good and exciting activities.
-
9:10 - 9:14It's all out there. Search online.
-
9:14 - 9:17Reach out and share with other teachers.
-
9:17 - 9:22Become a member of a learning community
of physics teachers. -
9:22 - 9:26Have the courage to start
and do it in class. -
9:26 - 9:32In my class, physics is
no longer difficult, scary, or boring. -
9:32 - 9:36My students know that physics
is all around us. -
9:36 - 9:38Even on my T-shirt.
-
9:38 - 9:42So, you see, teaching physics differently
-
9:42 - 9:44is physics-ly possible!
-
9:44 - 9:45Thank you.
-
9:45 - 9:47(Applause)
