The Greenhouse Effect

✧༺♥༻∞The Greenhouse Effect experiment∞༺♥༻✧

AIM: To Look At Climate Change And The Greenhouse Effect.

Materials:

1. 1 x plastic bottle

2.1 x Teaspoon Baking Soda and Citric Acid

3. 1 x heat lamp

4 1 x Thermometer

5. 100ml of water

6. 1 x rubber bung

Procedure:

1. . Collect 2 bottles, 2 lamps and 2 thermometers from the teacher.

2. Set up bottles and lamps beside a PowerPoint on a flat surface.

3. Pour 100ml water and baking soda.

4. Start to record your findings taken from bottle thermometer. These must be every 5 minutes.

The Water Cycle

This week for Climate Chaos we had to cut out 10 hexagons and explain how each of them went together.

Water Cycle is connected to Transpiration because transpiration is a step of the Water Cycle.

Transpiration and Water Vapour are connected because they are all the action of water vapour going up.

Water Vapour and Evaporation are connected together because they are from water (Oceans, Lakes, Rivers, Ponds) and the watering plants.

Water Vapour and Condensation are connected by when the water vapour rises it forms together to make clouds which is also part of the water cycle.

Evaporation and Condensation are connected because (evaporation) the water evaporates and rises and it clumps together to make clouds (condensation).

Condensation and Hurricanes are connected because they both form.

Hurricanes and Climate Change is connected because Hurricanes can change the climate and the surface of the Earth which can lead to disrupting weather patterns.

Water Vapour and Precipitation are connected because water vapour goes up into the clouds

Wind Power

Definitions:

1. Anemometer:
2. Beaufort wind scale:

MATERIALS

1. Skewers  
2. Vivid  
3. Tape  
4. Pencil
5. Pin  
6. Plastic lid thing

STEPS

1. Gather all the materials.
2. Tape the plastic lids to each side of the skewers.
3. Tape the skewers together.
4. Then, place the skewers onto the eraser.
5.  Put the pin through the skewers and eraser.

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper ( watch)

• Counter

• Recorder ( Chromebook or refill )

• Anemometer Manager ( Anemometer)

• Wind Manager

Instructions:

• Go to the measuring place and set up your wind gauge.
• Make sure everyone in your group is ready to start their roles.
• Record how many times it spins and record it in the table below.
• Count the number of spins in 15 seconds.
• Record it on your chart.

FINDINGS

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	0
2.	Old J Block site	0
3.	Grass hill in quad	0
4.	Tennis Court gate	0

CONCLUSION:

I think that there was no wind on the field because most of the people in our group were crowding around the wind gauge.

I think there was no wind at the olf j block site because there was a building right next to it making it so there was less wind.

I think that there was no wind on the grass hill because it was surrounded by buildings with not a lot of gaps, even though it was higher up, I think the buildings were blocking some of the wind, as well as some of the people in our group crowding it.

I think that there were trees around it as well as people crowding it and a fence.

Forensic Science

Forensic Science

Definition:

Forensic Science is a form of science that people use in crime scenes when trying to find criminals. 

5 Forensic Science topics;

1. White powder 
2.  Ballistics
3.  D.N.A
4. Fingerprint
5. Forgery

    

Fingerprints

Fingerprint characteristics

Aim: To look at the different types of fingerprints.

Materials: 

1.   Finger
2.   Ink
3.   Balloon

Steps

1.   Get your items and your friend.
2.   Carefully roll your thumb in the ink.
3.   Place your thumb on your balloon without moving it, carefully lift your thumb off the balloon being careful not to smudge your fingerprint.
4.   Blow your balloon up and look at your print.
5.   Repeat the steps with your index finger.

Insert pictures here of your fingerprints

Science Filter Experiment

Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are:

1.  Oil Filter 
2. Air Filter 
3.  Pool Filter
4. 
   

Materials

1.Funnel

2.Container

3.Filter paper

4.Dirty water

5.Pebbles

6.Fine Sand

7.Cup

8.Scissors (if using a bottle for funnel and container)

Process - ( use verbs or doing words in each step )

Step 1

Cut the bottle in half and using the top as your funnel.

Step 2

Put the top half upside down in the bottom of your bottle.

STEP 3

Add layers of filter paper, sand, and rocks to your funnel. Making sure to put the sand in the filter paper that is in a cone shape.

STEP 4

Get 1 cup of dirty water.

STEP 5

Pour the dirty water into the filter you made.

Findings

Minutes                          1. 52 drops in a minute.  43 minutes to fully drip through
Drops per minute:
Water colour:
Conclusion:

For our filter, it ended up not working because while we were filtering we accidentally knocked the filter over causing some of the water and pebbles to fall out. We also think it failed because we put the water in to fast causing it to fall through the sides and not go through the whole filter. After a failed attempt we got to add another piece of filter paper on top of the pebbles in a cone shape and retry. The first time the water almost didn't change, but the second time the water turned out almost like tap water with a little tint of yellow. With the second filration test the water dripped through alot slower than the first causing it to come out cleaner.
