SIMPLE EXPERIMENTALPROJECT SHOWING HOW TO MAKE A STEAM TURBINE FOR BOTH JUNIOR AND HIGH SCHOOL

A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft.

1. Cut a circle 3 inches across from a thick foil food tray. Pierce a small hole in the center, then snip in toward the hole with your scissors as shown in the image. Twist the sections slightly to make the blades. 

2. Punch two small holes in the top of a full, soda can—one in the center, the other about half an inch to one side. Empty the soda out and pour half cup of water into the can
3. To make the stand, cut a piece of thick foil 8 inches long and 14 inches wide. Fold in half lengthwise, then bend into shape as shown so it fits across the top of the can. Make a small hole 2 inches up on each side of the stand.
4. Fix the stand onto the can with a small screw. Then push a 4 inches long wooden skewer through the holes in the sides of the stand, threading the wheel in place as you go.
5. Make sure the blades of the wheel are positioned over the sma…

DISCOUNT AND COMMISSION MATHEMATICS LESSON PLAN AND LESSON NOTE FOR PRIMARY AND SECONDARY SCHOOLS

Monday
Meaning of Discount 
Finding cost and cash price on discounted goods
Resources  Inside out  Learn   mathematics Book 6, page  125 
items like; currency note Milo, biscuits, books, pencils, school bag



Meaning of Discount Discount is a reduction in the price of an article. It is often a certain percentage of the actual price of the article.
Examples 1. A table clock cost $200, and a 10% discount is given for paying cash. What is the cash price?
Solution
The discount = 10% of $200 =   10    x 200= 20 100
So Cash price = original price – discount                                                             Amount  =    $200 –  $20 = $180 

2. The selling price of a shirt is $900. The trader gives 5% discount for cash. How much is the buyer paying. Solution The discount = 5% of $900 = $45
So Cash price = original price – discount amount
                        = $900 – $45 = $855

Begin the lesson by showing them an image of a market where buying and selling is taking place, then ask them what is happening i…

ESTIMATION AND APPROXIMATION MATHEMATICS LESSON NOTE AND PLAN FOR BOTH PRIMARY AND SECONDARY SCHOOL

Monday Understand estimation and approximation
Round whole numbers to the nearest ten Resources  Inside out  mathematics Book 4, page  181 and 6 page 106 flashcards,  beads, jelly bean, glass jar,  currency note biscuits, books, pencils.
Introduction to estimation and approximation Estimation is a way of saying a sum is nearly about a figure or find something close to the correct answer. If we write 99, we say that it is nearly or about 100. Another word for estimation is approximation.  this sign means “approximately equal to”.
When rounding numbers, do notice the following: a. digits that are less than 5 are rounded down, I.e replaced by zero. b. digits that are 5 or greater than 5 are rounded up. i.e 1 added to the original digit.

Rounding whole Numbers to the Nearest Ten  When rounding whole numbers to the nearest ten, simply round up or down the last whole number Note a. numbers like 20, 30,40,90, 100 200, 300, 800, 1000, 2000 b. numbers like 21, 22, 23, 24, are all rounded down to the nearest t…
