Boat Testing!

This is the rubric I used to mark the Buoyancy unit. If they used the right language in their write-ups to explain why they floated or why they didn't float, they had the opportunity for full marks.

/20	Not Yet Meeting (1)	Beginning To Meet (2)	Meeting (3)	Excelling (4)
Boat Planning (Procedure/Drawing)	Incomplete	Drawing (no label, no steps)	Drawing (label no steps / steps no label)	Drawing, Labeled and Steps
Evaluation (Write-up)	Incomplete	Steps not laid out	Easy to follow steps for rebuild all info filled in	Write-up completed, detailed, easy to follow
Modifications - (Tested Once, Mod & retried)	No Trial		1 or more Trials
Buoyancy (Hold Weight)	0 grams	1 - 25 grams	25 – 100 grams	100+ grams
Group Work - (Present & Participated)	Off task multiple times	Off task a few times	On task	On task in class and out

Weight & Mass? What's the diff?

Science Experiment!

Page. 215 out of the Text Book

Exploring Mass and Weight

How are mass and weight measured? How are these measures related to one another?

Here is the page from the textbook with the procedural write-up:

Lab Report Template:

- In case you cannot find yours. You DO NOT need to print it, simply write down the topics and headings!

Who you callin' Buoyant?!

Who you callin' BUOYANT?!

Buoyancy and FORCES!!

First! - 25 min.
We will watch a short video on Buoyancy and experiments.

Second! 25 min.
Read  page 214 to the bottom of 217 in the science textbook.
Stop and focus on language and specific examples:

TERMS
Force - is a push or pull that tends to cause an object to move or change its motion.
Floating - occurs when an upward force on a object is equal to or greater than the force of gravity pulling the object down.
Non-balanced Forces - Objects in fluids may rise or sink if these two forces are unbalanced.
Gravitational Force - pulls objects down toward the centre of the earth.
Buoyant - the liquid exerting an opposite force and tries to push it upward.

Communicate:

1. How might someone measure someone's mass on the moon?
2. How might someone measure someone's weight on the moon?

Problem Solver - A Mystery

200g = .2kg

Gravity = 9.81kg(m/s^2)

Newton = kg(m/s^2)

Water vs. Molasses vs. Vegetable Oil
