Scared Pepper Challenge
Our Dark Box Creation
How to make a dark box:
You will need:
- Shoe box
- Sheet of paper
- Aluminium foil
- Ruler
- Pencil
- Cutter
- Scissors
- Black paint
- Paint brush
- PVA glue
- Needle
Step 1: Paint the inside of the box
with the black paint.
Step 2: Once the paint is dry, with
the ruler, measure the length from side to side, then make a 2cmx2cm square in
the middle of the box and use the cutter to cut it off.
Step 3: Use the aluminium foil and cut
off 2 2cmx2cm squares, with the tape, tape the squares on both of the square
sides you cut off earlier.
Step 4: With the needle, make a small
hole in the middle of both sides of the box.
Step 5: In the middle of the box, make
the paper the height of the box, after that, make a line to where the paper
goes from side to side inside the box, once that is done you have to stick the
both sides with PVA glue.
What is a Dark box for?
For centuries the technique was used for viewing
eclipses of the Sun without endangering the eyes and, by the 16th
century, as an aid to drawing; the subject was posed outside and the image reflected on a piece of drawing paper for the artist to trace.

DAVID CLARKE'S SCIENCE EXPERIMENT
Procedure:
Pour food colouring into a glass.
Add water.
Pick a white rose
After 2 hours
Next day
Results:
The rose turned blue
Conclusion:
The rose drinks the water and changes colour.
For my mini (quarantine) science experiment I attempted the “egg and bottle challenge”, this was an epic fail or I like to call it the “eggpic fail”.
The aim of this challenge was to get a full egg into a glass bottle without it breaking.
1. Get a pint glass of vinegar and leave a whole egg fully submerged in the vinegar for 2 days.
2. *2 days have passed* heat glass bottle.
3. Put egg sitting on the mouth of the bottle
4. Leave it for 2 hours and the egg should have slipped into the bottle (or at least have started to move into the neck of the bottle)
Now, for the science experiment that actually worked.
I attempted an experiment to show liquid densities.
1. First things first, get a skinny glass/test tube.
2. You will need; food colouring, honey, water, cooking oil, washing up liquid (a different colour to the food colouring).
3. Before adding the water you must first add your food colouring to the water (this is so you can see the water when it separates from the other liquids). Pour the same measure of each liquid into your glass/test tube- the order doesn’t matter.
4. Leave the liquids and wait for them to separate- this should only take a few minutes
5. You should now see all liquids separately in the glass
The liquids starting to separate
In these 2 photos you can see that all of the liquids have separated.
The liquids separate because they have different densities. Water sinks because it is more dense than oil. Solids are made from atoms and molecules, liquids are also made from atoms and molecules, which have a certain size and mass.
The liquids that are more dense are heavier and will sink to the bottom and the liquids that are less dense will stay on top. Density is the reason the liquids separate.

Equipment:
· Plastic volcano or cup
· Funnel
· Bicarbonate of soda
· Red food colouring
· Malt vinegar
· Measuring cup
· Kitchen roll
Safety:
ü Wear goggles
ü Wear lab coat
ü Wear gloves

Method:
Ø 1. Add funnel
Ø 2. Carefully open foil bag of
bicarbonate of soda slowly pour 10g into the funnel.
Ø 3. Now add a few drops of red food
colouring.
Ø 4. Measure out 15ml of malt vinegar and pour
into the cup remove funnel and watch the volcano eruption.
