Do snakes poop?

Have you ever wondered how snakes poop?

My student, Nathanael did.
He asked me that question during our discussion about reptile in Science lesson.
So, I searched it on internet and found this video.

Animal Kingdom

The kingdom of animals is fascinating. The interaction, survival, and beauty of animals is worth understanding and studying. Not that we're biased or anything, but we think ducks are the best animals ever. Check out your favorite animal or type of animal below to learn more about them. We also have lots of fun facts about animals, so enjoy, and we hope you learn something about animals along the way. Check it out on  http://www.ducksters.com/animals.php

What type of matter is fire?

Teaching Science lesson in my class is such a fantastic experience. There is always great moment in each meeting.

This week, we discussed about matters and their physical changes. Surprisingly, one of my students, Valerian, came up with a question "What type of matter is fire? Is it a matter of solid, gas or liquid?"

I think there are more curious children out there who have this kind of question in their mind. Hopefully, this will help. 

Well...
 

Matter occurs in four states: solids, liquids, gases, and plasma. . 

Solids

• A solid has a definite shape and volume.
• Examples of solids include ice (solid water), a bar of steel, and dry ice (solid carbon dioxide). 

Liquids

• A liquid has a definite volume, but takes the shape of its container.
• Examples of liquids include water and oil.

Gases

• A gas has neither a definite volume nor a definite shape.
• Examples of gases are air, oxygen, and helium.

Some introductory chemistry texts name solids, liquids, and gases as the three states of matter, but higher level texts recognize plasma as a fourth state of matter.

Plasma

• Plasma has neither a definite volume nor a definite shape.
• Plasma often is seen in ionized gases. Plasma is distinct from a gas because it possesses unique properties. Free electrical charges (not bound to atoms or ions) cause plasma to be electrically conductive. Plasma may be formed by heating and ionizing a gas.
• Stars are made of plasma. Lightning is plasma. You can find plasma inside fluorescent lights and neon signs.

So, What is the State of Matter of Fire or Flame? Is it a Liquid, Solid, Gas or Plasma?

For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in air and a fuel, such as wood or propane. In addition to other products, the reaction produces carbon dioxide, steam, light, and heat. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma.

Number Riddle part 2

Hi, my name is Nathanael.
I am the fourth grader of Batari School.

Check out my genius number riddle!

I'm a 5-digit number.
The digit 7 is in the tens place.
The digit in the thousands place is 49 divided by 7, multiplied by 97, added by 302, divided by 9 and subtracted by 100.
The digit in the ten thousands place is 1000 divided by 100 and subtracted by 2.
The digit in the hundreds place is the same as the digit in the ones place.
the digit in the ones place is the greatest even number start from 2 to 0.
What is my number?

Can you guess my number?

"PLACE VALUE HOUSE" GAME

Time runs so fast. Yes! It has been a week since we started the new school year. My 4th graders have experienced fun learning activities specifically in Maths subject. They played a lot of games- manual and online. They like "PLACE VALUE HOUSE" game the most. The game is very easy to play. EVERYONE can play it.

You need: -. a deck of playing cards -. a board -. a board marker Please note that ace = 1, kings = 0. Set aside the 10s, jacks and queens.

 How to Play:

1. Split students into even teams. Draw a roof for each team on the board. 
2. Draw spaces for the places of a number, depending on which place values you want them to play with. Each team should also identify each place value.                                                          Ex: _____________  __________  __________   __________  __________        Ten Thousands   Thousands     Hundreds       Tens               Ones
    
3. Have one learner from each team draw a card. As a group, the learners should decide where to place the card on the place value spaces (facing down)to make the largest possible number. Once the card is placed, it's locked into that place until the number is completed.
4. Repeat step 3, until everyone gets a turn. Finally, you turn over the cards and read off the number the group come up with. 5. If a team comes up with the largest number, they get to add a wall to their house. The winning team is the first to build a house.
