Explore Forces and Motion: Do 1st in Class

Do 1st! They are all related to Force & Motion!!! Find your new seat! (Name cards on the desk) Write your question and answer on your new do 1st What do the following pictures have in common?

Announcements • Quiz #1 on Friday • Homework Packet Due Thursday • Raven Way Expectations Review: • Coming into Class (Quickly, Positively, & Calmly) • Bathroom Breaks • Leaving Class (Be cool to your peers!) • Positivity  (Introducing The Shout Out Wall, Reinstating the Weekly Raffle, and Introducing The Ear)

Agenda for the Week… • Today is the official beginning of our last major unit of study together: “FORCES AND MOTION” • We have VERY limited time to complete a lot of information, let’s make it count!

Agenda for the week • For this unit, I am going to try to have regular mini labs to get you up and out of your seat “DOING SCIENCE” • You must have exceptional behavior and use your quiet partner voices for this to work. REMEMBER: You all want science to be fun, but it has to be a safe and orderly environment. • Many of the materials (cars, balls, etc.) I have borrowed from friends. PLEASE TAKE EXCEPTIONAL CARE OF THESE ITEMS. • Lost or stolen materials = NO MORE LABS

Agenda for the Unit… • In addition to mini-labs, this week you may have an outside lab. • In order to earn this privilege, you will need to meet class expectationsas well as complete a pre-lab sheet. • I have planned to do a super fun activity at the end of every week if as your behavior and attitude warrant me doing so. • *I have scheduled our Frog Dissection! We’re just waiting for our frogs to come in I will give you all the dissection date as soon as they arrive!

Today we are going to… • Learn some of the very basic vocabulary • Position, Motion, Distance, and Speed • Watch a couple of videos • Take some guided notes • Participate in a Mini-Lab • Learn how to calculate speed.

Please title your notes “Forces and Motion” Then copy the diagram and words. King Henry Died Unexpectantly Drinking Chocolate Milk

Preview of what we are going to talk about this week…. “Laws of Motion” • http://player.discoveryeducation.com/index.cfm?guidAssetId=CDA9C235-0EC4-4CA5-A713-B920EBD189D2&blnFromSearch=1&productcode=DSCE

Position • POSITION is the location of a place or object. • Often you describe where something is by comparing its position with that of something else

Reference Points • Each time you identify the position of an object, you are comparing the location of the object, you are comparing the location of the object with another location or place • The object or location to which you compare other objects or locations is called a REFERENCE POINT.

Video: “Bodies in Motion” • http://player.discoveryeducation.com/index.cfm?guidAssetId=514D72E8-8C86-4CFE-8FC0-044F1A32DBAA&blnFromSearch=1&productcode=US

Distance • DISTANCE is the measurement of two positions • In science, we measure distance in METERS • Kilometers for long distances • Centimeters for short distances

Distance can be either straight line or a measure of a path taken… Question: How would the distance of the path of this maze be different from a straight line measurement?

MOTION… • MOTION is the change of position over time. • Motion can be either: VERTICAL HORIZONTAL

SOME IMPORTANT THINGS TO NOTE…. • Motion does NOT indicate how quickly something changed position • This is SPEED, something we will learn in a moment • Motion can change direction

Check for Understanding… • What is the name for the location of a place or object? • How does scientists measure distance? • Motion can be __________ or ______________. • The location or object to which you compare other objects or locations is the ____________.

What is the name for the location of a place or object? • POSITION • How does scientists measure distance? • In METERS • Motion can be __________ or ______________. • Motion can be VERTICAL or HORIZONTAL. • The location or object to which you compare other objects or locations is the ____________. • REFERENCE POINT

Finally, what is speed??? • Speed is a “rate of motion” • It is measured as a distance over time • SPEED = DISTANCE TIME • Or speed = m/s

Mini-Lab: How can you measure speed? • iPods, Smart Phones • Expectations

Mini-Lab: How can you measure speed? Turn to page D16 in the textbook. You will work with in groups of 3 to complete the short task “EXPLORE SPEED”. You have 5 minutes to complete this and turn in the “WHAT DO YOU THINK?” questions as part of your exit ticket. 2 people to roll balls Team Captain will use stopwatch to record time.

DISCUSSION: SPEED • You actually already know a great deal about speed. • What does the speed limit on the road stand for? • MILES PER HOUR • Or miles hour • Remember our formula for speed?

Calculating Speed A wheelchair racer completes a 100 meter course in 20 seconds. What is his speed? 5 meters per second!

Calculating Speed • If a car travels 400 meters in 20 seconds how fast is it going? • Answer: 20 m/s

EXIT TICKET • Mr. K’s class is 10 meters away. If it takes you 8 seconds to get there, what is your speed? • The Gym is 100 meters away. If it takes you 90 seconds to walk there, what is your speed? Put your exit ticket in THE BIN and work on your homework when you’ve finished. 
