Hamer Grade 2 : Wednesday, June 10

Entry for Wednesday, June 10

Today in History

On this day in history, June 10, 1905, the first forest fire lookout tower was placed in operation in Greenville, Maine.

Forest fire lookout towers play an important role.

A person in the tower can see for miles and miles because of the height of the tower.

They are constantly on the lookout for smoke or flames.

The quicker they spot a fire, the quicker fire fighters can reach the scene and begin putting the fire out!

"We think forest fire lookout towers are very important structures!" they announce from the park across the street from the school.

Prepositions of Place

Prepositions of place tell where someone or something is located.
(There are also prepositions of time which we will study next week.)

There are many examples of prepositions of place.

It's fun learning about prepositions of place.

Your Reading Task

Your task is to write four sentences with each one containing two prepositions of place. Be sure to highlight or underline the two in each sentence. Don't forget to add a title.
Mr. Hamer will provide a couple of examples.

Prepositions of Place

1. Mr. Hamer looked behind his desk and found the pencil under the chair.

2. The puppy hid inside the box that was next to the cupboard.

"We are Preposition Pros!" they exclaim.

Math Learning

Probability is the chance of an event occurring. We can use words or numbers to describe probability.

While the smaller cards may be tricky to read, I want you to look at the top four larger ones.

Impossible
When you know something will never have a chance of happening...then we say it is impossible.

"It is impossible that I will wake up tomorrow on the planet Mars."

Even Chance
When it is equally likely an event will occur, you have an even chance.

"There is an even chance of flipping a head or a tail when I toss a coin up in the air."

Unlikely
Something that probably won't happen.
"It is unlikely that it will snow in June in the city of Ottawa."

Likely
Something that will probably happen.
"It is likely that I will eat lunch today."

Your Math Task

Copy these four sentence starters and complete the sentences with a scenario of your own choosing.

1. It is likely that...

2. It is unlikely that...

3. There is an even chance of...

4. It is impossible that...

"Prepositions are cool!" they say as they sit "beside" each other.

Student Sharing

Some more student sharing of work.

Some great language work.

Nice math effort.

Still more math.

Lovely!

She's smart! Thanks for sharing, G.M.

"We love seeing each other's work!" she states with certainty.

Science (With No Work)

We continue to learn how simple machines help to make work easier. Lets check out the lever today.

Lever

For levers to help us, they need a balancing point to assist with the work. This balancing point is called the fulcrum.

It is like the hinge of the lever.

In the class 1 lever above, the fulcrum is a smaller stone that will allow your effort to push down on the bar which will then push up beyond the fulcrum and lift the heavier rock.

In the class 2 lever, the fulcrum (balancing point) is the wheel and axle area of the wheel barrow. (Yes, two simple machines in one!) By lifting the handles on the wheel barrow, you can then push it along by the wheel.

In a class 3 lever, the balancing area (fulcrum) is in your hand at the handle. That's where the pivot or turn happens as you lift up on the handle with your other hand. Then the spade of the shovel lifts the load.

We see our wheelbarrow again.

Hey, check out the seesaw or teeter totter as I used to know it. You and a friend can sit on the different ends...but what if your friend is way heavier than you. They could keep you in the air for a long time. (You could also lift your heavier friend if you have one of you move down the plank of the teeter totter! You could research that one!)

The baseball bat is also another example of the lever. Just a simple swing could send the ball way farther than you could even throw it!
