EXAMS

I'm so proud of all of you that study ver hard for all your exams !!!


:D

Here there come the exams !!

I just want to remind you that the exams are coming....
study very hard from your laboratories, Practice Book, Science Book, and Math Book.

:)

Make a Graph

Hi everyone !!
Here is a link in which you can desing your own graph.

OVERESTIMATES AND UNDERESTIMATES

Overestimate : An overestimate happens when you round up.
Ex:
Pedro has 36 DVD´s of series and 57 DVD´s of movies. If he has 100 spaces, does he have enough for the DVD´s? Round to the nearest ten to estimate the sum.

36 rounds up to 40
+57 rpunds up to 60
-------
100 He has enough spaces

Each addened was rounded up so the estimated sum is greater than the actual sum. It is overestimate.

Underestimate : An underestimate happens when you round down.

Sara was in charge of seating the school show. She has set up 34 seats in the center and 23 seats on each side. She is expecting 70 people. Has she set up enough chairs? Round to the nearest ten to estimate the sum.

34 rounds down to 30
23 rounds down to 20
+23 rounds down to 20
-----
70 seats is the estimated sum.

Each addened ws roundes down, so she estimated the sum, 70, is less than the actual sum. It is an underestimated.

Estimate each sum by rounding to the nearest ten. Then tell whether each estimate is an overestimate or underestimate.

ex: 36+47 : (40+50) we overestimate.

1. 23+44 :
2. 66+87:
3. 98+27:

Let´s work !!!

I hope you liked the art class of Monday, and if you want to made your own color wheel here is everything you´ll need :D

What you'll need:

• Pattern
• Cardboard
• 3 pieces of cellophane paper: red, blue, and yellow
• White glue
• Scissors
• Hole punch

1. Cut out the pattern for the color wheel, remember that we use a CD to make the pattern.
2. Trace around this pattern on cardstock six times. Cut out each piece, making sure to cut out the center.
3. Cut the cellophane windows just smaller than the outside of your frame, but larger than the inside measurement.
4. Sandwich a colored piece of cellophane between two pieces of cut out cardstock. Glue together to make a window. Repeat until all three windows are made.
5. When they are dry, stack on top of each other and punch a hole in the center of the narrow end and fasten together with a paper fastener.

Also here are two liks of some games that i found:

The Color Wheel

The Color Wheel
Color wheels show us how colors are related. They remind artists how to mix and think about colors.

The primary colors are:
-red
-blue
-yellow

Primary colors cannot be made from other colors. Artists create all the other colors of the rainbow by mixing together the primary colors.

The secondary colors are:
-green
-orange
-violet (purple)

Secondary colors are made by mixing two primary colors. Each secondary color is made from the two primary colors closest to it on the color wheel

Just by mixing these colors, you can get all the colors of the rainbow:

vacations :)

Hi to everyone !!!

I hope you´re enjoying your vacations !!!

Have fun, sing, dance and rest !!! jeje

I miss u a lot, I can´t wait to see u !!!

Miss gaby ;)

Amphibians with Tails?

Salamanders are often confused with lizards. But don't let yourself be fooled: they are definitely a part of the surprising and numerous family of beings with a ''double life'' - those who live in the water and on land. (Amphibious)
There are some 300 varieties of salamanders, but all are defined by the name of their order: Caudata, that means ''with tail.''

Salamanders are fascinating because of their colors, their strange shapes. For example:

The Spotted Salamander

There are large salamanders, sometimes growing over nine inches long.
Their skin is bluish-black or dark gray, and they have two rows of round yellow or orange spots down their backs. Their bellies are slate gray.
Spotted Salamanders live in forests where there are pools of water in the Spring, or nearby ponds.
Adult Spotted Salamanders spend most of their time underground.

Lesson 8 Energy to Mix and Split

Energy to mix and split

A mixture contains substances that are mixed together but are not chemically combined.

Air is an example of a mixture as it contains a number of different gases including oxygen, carbon dioxide and nitrogen.
A solution is a mixture of a solute and a solvent e.g. salt and water.
A solute is the substance which is dissolved (salt) and a solvent is a liquid in which a substance dissolves (water).

Homogeneous and Heterogeneous Mixture

Homogeneous

These mixtures are made up of more than one phase or of different parts and can be separated physically. The different components are visibly distinguishable from one another.
Ex: A chocolate chip cookie, a piece of quartz containing a vein of gold. granite, oil and water, and a bowl of raisin bran cereal.

Heterogeneous

Have only one phase, or have a uniform appearance throughout, and any portion of the sample has the same properties and composition. Each region of a sample is identical to all other regions of the sample.
Ex: salt water and rubbing alcohol, are considered homogeneous because they are in one phase.

Sometimes it is necessary to separate solutions and to do this we have a number of separating techniques including filtration, evaporation, and distillation.

Filtration
Is the method used for separating an insoluble solid (a solid that will not dissolve) from a liquid. A tea bag is an everyday example of a filter. It works because it has small holes to let the liquid through but blocks the larger pieces of solid.

Evaporation

Is a method of separating a soluble solid from a solvent e.g. salt and water.

Distillation
Distillation is a process involving the vaporization of a liquid by boiling it and then condensing the vapor by cooling it. It can be used to purify a liquid (e.g. to obtain pure water from a salt-water solution).

DISTILLATION - EVAPORATION - FILTRATION

Lesson 7 The power of magnets

Lesson 6 Electric Energy

Hi guys, in this leson we saw how circuits work.

Here is the presentation and also is the link of the place in which you can play the game.

Types of Machines

In this lesson we learned about several types of machines

The Simple and The Compound Machines


The simple Machines are the most basic like:

• the inclined plane
• the lever
• pulleys
• wedges and screws

The Inclined Plane

Is used to lif to objects by sliding or rolling them.

http://www.youtube.com/watch?v=pG_kT565-XQ&feature=related



The Lever

It let us apply the force at one point by making a smaller force at another point. A lever has a fulcrum, and an effort point (were we make the samller force ) and a resistance point (where the large force is applied).

http://www.youtube.com/watch?v=pG_kT565-XQ&feature=related




The Pulley


This lifts weights, they change the direction in which the forces act. For example, when we pull down on the end of a rope on a pulley, the load attached to the end of the rope rises.

A wedge

Is use to cut or separate things

A screw

It is used to fasten things together

Compound Machines

The compound machines are combinations of simple machines, some daily life examples are: cars, electric stairs, computers, etc.

Acceleration

Hi guys !!!

Here is the link of the activity that we made in class, changing the gradient we make the truck travel all the track !!

How does changing the gradient affect the car's speed?


How does friction affect the distance on a surface?
