Wellness 10

Subject:Wellness 10
Unit: Dimensions of Wellness
Topic: Physical Dimension
Evergreen Curriculum Objectives

Website:
FitQuest - WebQuest

Explain how you would have your students use it.
This website contains a webquest about personal fitness. After teaching students and having them participate in various sports, weight training and personal fitness activities I would use this WebQuest at a time when the gym is unavaliable.

Explain how you think it would improve your student's learning.


This webquest would enhance students learning because they are to apply their knowledge about personal fitness to creating a fitness plan. Students can learn how to create their own personal fitness plan that is unique to meet their needs. Also these websites will be resourceful to the students for future reference.

Math 9 Perimeter

Subject: Math 8
Unit: Geometry/Measurement
Topic: Length
Curriculum: Evergreen Curriculum
G/M-48
calculate the perimeter of
  1. composite figures given the lengths of the sides
  2. figures given partial, but sufficient, information

Website: Shodor Interactive - Perimeter Explorer
Shoder Interactive - Area Explorer

Explain how you would have your students use it.

In my internship I taught a unit on area and perimeter a Math 9 Non-semestered course. I was exposed to the frustration students were having between identifying the differences between area and perimeter . I used a lot of hands on activities but found that the students were just going through the motion and did not have to identify the differences.

This website I found contains a variety of activities for Math. Two Java Applets in particular I found that will help students are the perimeter explorer and area explorer. They both use a grid lines to identify the magnitude of one. Students are asked to find the perimeter of irregular or square objects. They use color to identify the objects on the grid.

I would use this assignment as an exploration to find perimeter and area of objects. Students would answer 5 questions from each applet. The websites also contain a feature that corrects you answers and contains them in a chart that compares the perimeters and areas of each object. What I would guide the students to notice would be that the area of objects can be the same but the perimeters can differ, and vice versa. The chart allows students to conjecture this difference.

I would use this as a exploration activity in class after i have done a formal lesson on perimeter and area. The students would be evaluated on their conjectures by answering short answer questions.


Explain how you think it would improve your students learning.

I believe students would benefit from this because they can access a variety of questions in a short time, and the grid paper helps them notice that area covers the object and perimeter is the distance around.

Math A30 Data Analysis (WEB 2.0)

Subject: Math A30
Unit:
Data Analysis
Objectives:
Evergreen Curriculum
B.1
To list and describe the methods used to collect data.
B.2
To obtain data for real-world situations by using simulations (such as Monte Carlo simulations).
B.3
To review the methods for determining the measures of central tendency.
B.4
To construct box and whisker plots from simulated data.
B.5
To define and utilize the concept of percentiles (including the first, second, and third quartiles).
B.6
To solve related problems using statistical inference.

Website: Stellar Survey

This website allows you to create a free online survey. You can create multiple choice questions, rating scales, short answers etc. (25 types of questions). Once you've created your survey you can create a link to your survey that you could post on a website or e-mail to other people in order to collect your data. Then they have a variety of resources that help you to display your data and interpret it.

When I saw this website Math A30 Data analysis came to mind. I would use this website as a method that students can use to collect data that they will interpret. One of the curriculum objectives in this unit is to collect data from real world situations by using simulations. Students could create their very own survey in each their peers will answer. Once they have collected their data I would have them construct box and whisker plots as well as demonstrate the first, second and third quartiles.

One key fact to tell students when they creating their own survey is that it must be numerical data for example How many siblings do you have? compared to What color of pen do you prefer to use? The question the students will be surveying will need to quantitative not qualitative.

I would use this as an overall project for this unit. Incorporating objectives as they arise in each lesson.

I'm excited to give this a try. I'll post again if I do to let you know how it goes.

I think students would benefit from it because it reaches a lot of the Common Essential Learnings found in the curriculum such as:
  • Communication; using e-mail to communicate or a website
  • Numeracy; understanding the quantitative data collection
  • Critical and Creative Thinking; students can create their own survey about a topic that interests them. Critical thinking will occur curing interpreting the data.
  • Technological Literacy; Reading the website as well as understanding how to navigate and use the website
  • Personal and Social Values and Skills; Students can personalize their survey and incorporate an investigation about what is important to them
  • Independent Learning. Students must create their own survey and interpret their own data. As an extra depending on the topics they chose they research what the percentages are if it was a world survey.

Math A30 Relations and Functions

Subject: Math A30
Unit: Relations and Functions
Topic: Quadratic Functions - Standard Form
Objectives: Evergreen Curriculum
Website: Graphing Calculator


This website contains a free online graohing calucaltor. Depending on the budget in your school some may not have access to handheld gaphing calculators, therefore websties like this can benefit your students.

I would use the online graphing calcualtor to assist students in a discovery lesson in which the students will conjecture the applications of each variable that is in standard graphing formI would give students a handout of quadratic equations such as:
y= 2x^2
y= 2(x-3)^2+5
y=2(x+3)^2+5
y=8(x+3)^2 +5
y= 2(x+3)^2 -5

Students would copy down after a sketch of what each of the graphs looked like. The equations' variables would change slightly becasue I want the students to visually how the graph is affected by a changing a variable. In conclusion I would want students to realize what purpose each variable has in the equations.

Example:

a = changes the width of the parabola, smaller the variable the larger the parabola

h = x point of the vertex will move the parabola from left to right

q = y point of the vertes will move the parabola up and down

I belive students would benfit from this application of graphing because they can visually see the graphs and make a connection between the equation and the graph. I would move on from this lesson by going on to discuss min, max, range, domain etc.

Math 9 Algebra

Subject: Math 9
Unit: Algebra
Topic: Solving Equations
Objectives: Evergreen Curriculum
Website: Virtual Manipuliatives - Algebra Balance Scale

This website contains vairety of virtual manipulatives for mathematics ranging from K-12 and around topics such as algebra, geometry, measurement, numbers and operations, Data analysis and problem solving. In Math 9 their is a unit on algebra. Many times this is the first time students have begun to solve equations. The idea of keeping equations balanced when solving can be complicated to some students. The metaphor of keeping the equation balanced on a scale helps students visullay see the idea.

This website has a java applet that allows students to create a balanced equation on a scale then solve the equation, but if the equation is not solved correctly the scale becomes unbalanced. I would use this website not only to demonstrate solving equations but allow students to use the virtual manipulative as well. After teaching students how to create ones and zeros when solving for X, I would use this applet as an assignment that day.

The assignment would be to answer 15 questions that the applet gives you and to answer 2 questions that you create. I believe maniplulatives enhance student learners because they help reach visual, tactile and concrete learners. It gives students a more concrete idea of how to solve equations. Another resource they can us in order to successfully understand and apply the concept.

Math A 30 Angles and Polygons

Subject: Math A30
Unit: Angles and Polygons
Topic: Six Trig Functions
Objectives: Evergreen Curriculum
Website:
Six Trig Functions

This website contains an applet that allows you to change the angle along the unit circle and it will calculate the sin, tan, cos, sec, cosec, and cotan. I would use this applet in a discovery activity. I would have students find which quadrants each are positive and negative in and why using the trigonometric ratios. I would use guided questions to help the students find each. This could be used as a set to the lesson.


Students would benefit from this becasue they are actually conjecturing and taking ownership of their own learning. After we have discovered the positive and negative quadrants for each trigonmetric ratio, then i would give students the common acronym to memorize the quadrants (CAST: C= Cosine is positive , A= All trigonometric ratios are positive , S= Sin is positive, T = Tangent is positive)

Science Grade 5

Subject: Science Grade 5
Unit: Human Circulation
Topic: The heart and it's functions
Objectives:
Evergreen Curriculum

Website: Argosy Multimedia

This site contains many interactive applets. In the grade 5 science curriculum one of the objectives is that students should be able to identify parts of the heart and understand the functions.

I would use this website in an inquiry lesson about the heart. I would create a guided handout that will guide students through the names of the chambers and their functions as well as the arteries. This website allows students to explore the heart. I believe students would benefit more learning from a website like this compared to an overhead that just displays the diagrams. Students can take ownership of their own learning.

Biology 30 Genetics

Subject: Biology 30
Unit: Genetics
Topic: Mitosis and Meiosis
Objectives:
Evergreen Curriculum


Website: Cells Alive - Meiosis
Cells Alive - Mitosis

Cells alive is a website tha contains interactive diagrams, activities, and processes. This is an excellent site that is a good resource for biology teachers.

I would use this site in Biology 30 as a demonstration of the two processes of Mitosis and Meiosis. I would have the students compare and contrast the two processes by viewing the interactive demonstration. The website allows you to stop and view more details about each stage this will allow the students to read more indepth about each stage in order to compare.
Another benefit for the students is the fact that it is on the web will allow the students to use the interactive applet to study from.

This adds more realism to the two processes allowing more learning to occur.
Here is an example of photos of each stage in each process. The applet allows the students to view how we get from one stage to the next.
