Linear Velocity has a direction and speed. More info to come soon.
Distance vs. Displacement
Distance is how far you have travelled
Displacement is how far you are from your starting point.
*****Test on Tuesday March 13th****
We will be learning about Newtons three laws and their applications.
First Law -An object at rest stays at rest, and and object in motions stays in motion unless acted on by an unbalanced force.
Second Law- The force acting on something is equal to the mass of the object times acceleration F = M x A
Third Law - For every action , there is an equal and opposit reaction. Action ---> <--- Reaction
Science Vocabulary to know
Force = Push or a Pull
Acceleration = Change in Velocity or Direction
Velocity = Speed and Direction
Speed = Distance / Time
*- Review sheet is on the left with a chapter on forces.
Finish Hunting the Elements Activity
1) ********Atom Tour Test -Socrative on-line test.
2) Demonstration of "Hunting the Elements"
Students will work through 20 elements to compare their characteristics. We will use this information to create our own periodic table and to understand how the periodic table of the elements helps us understand elemental properties and characteristics.
Here is a link to the element cards for our activity this week. Please use these if your are behind in class, or sick.
Practical Exam - Separating Mixtures
Students will use their knowledge to separate a mixture of solids by using their knowledge of the properties of matter. There is a review on Wednesday January 24th to plan for this test. Success will be separating their mixture into all of the separate components.
Ecocycle - I care about clean air
Lesson 17: Separating Solutes : (3 Class Periods)
Students use paper chromatography to separate an ink solution that contains several dye solutes and they apply this technique to solve a mock crime.
Inquiry 17.1 Analyzing Inks
Inquiry 17.2 Comparing Inks
Inquiry 17.3 Identifying Inks
P4 - Charlee, Maddox, Ella and Kyle
P1 - Quinn, Ben and Bryan
P3 - Alex, Quetzaly, Grace, and Anica
P2 - Naz, Daniel, Cassidy, and Ian
IN - What properties have we studied this year so far?
Answer - Density (Mass, Volume), Changes of State, Thermal Expansion, Solubility (Solvent and Solute), Insolubility, Dissolving, Magnetism, Miscibility, Immiscibility. Shape, Color.
Finish and Gallery walk to choose Stain Lab poster winners.
Continue - Making things Stronger
Researching Solvents poster design and presentation - students will be creating posters with their labs and data that will be presented to the other classmates.
Lesson 16 - Researching Solvents
Students will be learning about how solvents are used in removing stains. They will review the properties of solvents and solutes in a solution, conduct an experiment to test their hypothesis on the solvents, and then create posters with their group to present their data. They have a short quiz on Friday January 12th on the solutions and solvents reading.
Lessons learned from our first half of the year- I collected all of the most popular comments from the post-it notes that you created on your first day back. I think you have all been very successful. Please read through these and think about what you wrote down and how YOU can be better this semester.
