Dust turns sunsets orange and red. It does other good things, too. But dust and other particles can also make you sick – especially if you have asthma or allergies.

We are going to look for this air junk in your house. To do this you are going to make junk detectors.

What You Need

• An 205 mm x 255 mm piece of cardboard
• 6 pieces of sticky stuff.  Each piece should be 40mmx90mm.
• 6 pieces of string about 30cm long.
• Sticky tape
• A magnifying glass or digital microscope

What to Do

1. Get a copy of the pattern page
2. Cut out 6 collectors, using the pattern from the page
3. Fold each collector and cut out the inside window.
4. Then flatten the collector
5. Write the location and starting date and time on each collector
6. Hang the collectors wherever you are curious about the air. Or use these suggested locations: - above your bed, near where you breathe, inside or outside of a window, near a heating vent or anywhere else you like.
7. Cover the window on the collector with the sticky label or tape. Put the sticky side up or out
8. Wait a couple of days and take the collectors down. Write the ending date on each. Don’t touch the sticky stuff.
9. Take your collectors back to school and use a microscope or digital microscope to help you identify what you have collected.

Visitor attractions like Alton Towers and Legoland produce travel brochures to entice visitors to ‘take the next exit’ and visit them. Each amusement ride in the parks is described as ‘incredible’, ‘unbelievable’ or amazing’.

Ripe pineapples contain enzymes.

In this experiment you will use the enzymes in the pineapple to digest the molecules in jelly.

Collect - 1 container containing part of a pineapple
              1 packet of jelly

Method :-

1. When you get home from school, make up the jelly as directed on the packet.
2. When cool, pour the jelly into the container and leave the jelly until it is set.
3. Take the ripe pineapple out of the box and cut a cube out of it. Make sure that every side of the cube has been freshly cut.
4. Place the pineapple cube on top of the red jelly.
5. Observe any change that takes place in the jelly around the pineapple.

Results :-

Describe the changes that occurred in this experiment.



Conclusion :-


 

Flip books consist of a series of cartoon drawings over many pages. When you flick through the pages very quickly, the cartoons seem to come to life. This is an easy way of making your own sort of animated movie.

Your task is to make a flip book of cartoons which show one aspect of enzyme function.

For example, you could use a picture of a snowman to represent an enzyme. He could use his hands to build a large snowball from two small snowballs. The snowballs here would represent molecules. If the temperature increased and the snowman melted could he make large snowballs any more?

Your flip book must have a title page saying which aspect of enzyme function is being demonstrated. The enzyme, substrate and product must also be labelled at least once in the cartoons.
