Translucent Effect (Experiment)

Good morning! Here is a cool experiment. Materials you need:

• A sheet of white paper
• Oil 
• A straw
• A torch or some source of light
• Thread
• Scissors
• Sellotape
• A dark room or place in the house
• A member of your family can help
• Notebook

Procedure

1. Cut a piece of thread and stick it to the paper. Hang the paper to the ceiling in front of a wall (if it's dark better) and leave it there 15 cm aprox from the paper to the wall.

2. Light the paper with the torch and observe how light can pass to the other side. Write this on your notebook. Can light pass to the other side and hit the wall?

3. Using the straw, put some oil on the paper. Be careful and don't drop it to the floor. Half of the paper should be covered with oil. The oil will be absorved and it will spread along the paper. In the end the lower half of the paper should have oil.

4. Light the paper over the oil part. Compare with the other part.

Write your conclusions about this. Why does this happen? Have you seen something not normal?

Enjoy! 😊😎

Explanation:

Only opaque objects, by blocking light rays, form shadows. Paper is not opaque. It is translucent. The paper blocks much of the light rays. The oil, by penetrating into the fibers of the paper, creates small transparent cracks that let light through. This is not the case with water, which cannot easily penetrate between the common paper fibers.

Light

What Is Light?

Annie's family was having a bonfire last weekend. It was getting dark outside, so she stayed near the bonfire. But that made her curious: How do bonfires create light much like the Sun does? So, Annie asked her dad.

He explained that, like the bonfire, the sun burns gasses to emit (or give off) light. However, the sun burns different types of gasses, which explains why the sun gives off a different color of light than the bonfire.

While they use different types of gasses, there is one main reason that both emit light: the burning of gasses causes a chemical reaction that creates electromagnetic energy, which is a type of energy that takes the form of magnetic and electrical waves.

In physics, waves are the invisible vibrations that affect objects and even space to create light, color and more. The electromagnetic energy created from the burning gasses is what makes light.

But there's much more to be learned about light. In fact, light has different behaviours depending on the type of object that it hits. It can be reflected, refracted, absorbed or transmitted.

Light has three main properties: it is an electromagnetic wave, it travels in straight lines and it moves very fast. Light travels at the speed of light which is the fastest speed possible in the universe. That is 300.000 km per second!

Watch this video and write the most important ideas in your notebook.

Then make a comment telling me what aspect of light you like most and why.

The Old Maid

I'm sure you remember this game! Read the instructions and play with your family! Do you have cards at home? I hope yes!

Old Maid is a constant favorite with children and lots of fun for families playing cards together. Colorful decks made especially for the game are popular, but regardless of the playing cards used, the rules are the same.

This game only requires a standard deck of cards and 2 to 8 players. Players try to get rid of all the cards in their hand before their opponent does by drawing from their opponent’s hand and discarding pairs. The player left with the “Maid” loses.

The Pack

The standard 52-card pack is used, however, one of the four queens is removed, leaving a total of 51 cards.

Object of the Game

The goal is to form and discard pairs of cards, and not to be left with the odd card (a queen) at the end.

The Deal

Any player shuffles the pack and deals them around, one at a time to each player, until all the cards have been handed out. Players do not need to have an equal number of cards.

The Play

Each player removes all pairs from his hand face down. If a player has three-of-a-kind, they remove only two of those three cards. The dealer then offers their hand, spread out face down, to the player on the left, who draws one card from it.

This player discards any pair that may have been formed by the drawn card. The player then offers their own hand to the player on their left.

Play proceeds in this way until all cards have been paired except one - the odd queen, which cannot be paired - and the player who has that card is the Old Maid!

Change the game

See how the game changes if you decide the winner is the person left with the Old Maid. Call the Old Maid something more appealing like the superhero, the princess, the great king, the old king or the secret spy using a Joker.
