Science Week 2: Pizza Ovens

Renewable Energy
Aim: To make a solar powered oven

Equipment:

1. Sellotape
2. Scissors
3. Pizza box
4. Straw
5. Marshmallow
6. Biscuit
7. Glad wrap
8. Tin foil
9. Black plastic
10. Ruler
11. Vivid marker
12. Newspaper
13. Plastic Plate

Steps:

• Cut out the flap on the lid of the pizza box so that it is 5 cm around the edge
• Sellotape some tinfoil on the inside of the flap
• Sellotape some glad-wrap so that the whole you have cut on the pizza box lid is covered over with glad-wrap
• Put a piece of black plastic on the bottom of the inside of the box. 
• Make a paper square that fits inside the pizza box and lays around the edge
• Put a marshmallow on top of a chocolate biscuit, place it on a plastic plate and put it in the solar oven
• Put it in the sun to cook.

Conclusion:

Our experiment didn't work exactly. I think it should be in a place that the sun comes out more often and is close to our "OVENS". The smores were DELICIOUS.

Science (Solar Pannels)

Aim: To find out what colour attracts the suns heat.

Hypothesis:

I think that the colour is going to be silver/Tin foil.

Materials:

1.  1x Tin foil cup
2.  1x Clear cup
3.  1x Black plastic bag
4.  1x Small black bag
5.  1x Heat lamp
6. 1x White paper
7. 1x Thermometer
8. 1x Tin Foil 
9. 1x Plastic cup

Steps

1.   Collect the equipment
2.  Set it up, Put the white, tin foil and the black bag on the table.
3. Put with clear cup on the black bag in the middle
4. Put the little black bag over it
5. Put the white cup in the middle of the white paper
6. Put the tin foil paper in the middle of the tin foil
7.  Plug in the heat lamp
8.  Pour the water
9.   Wait 15 minutes
10. Record your findings

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16.c	16.c	16.c
15	20.c	25.c	19.c
30	20.c	35.c	20.c
45	20.c	30.c	20.c

Conclusion

This is a photo of all of the cups. Throughout this the black one spilled as we let the thermometer. 

The highest was the black one even though it was on the side. 

This was amazing 

Science - Greenhouse afect

Aim: To look at climate change and the greenhouse affect

Aim: To see how hot it could get with a heat lamp

Materials

1. 1 plastic bottle
2. 1 Teaspoon Baking Soda and Citric Acid
3. 1 heat lamp
4. 1 Thermometer
5. 100 ml water
6. 1 rubber band

Procedure:

1. Come and collect all of the materials from Mr Palmer.
2. Setting up the lights, bottles, thermometers and bungs.
3. Mr Palmer adds the baking soda mix along with 100ml of water.
4.  Wait for 5 minutes and start recording the temperature.

Variables:

All water added to the bottles was from the classroom tap

Minutes	Bottle 1: Water	Bottle 2: CO2 Gas
0	18.c	18.c
5	25.c	18.c
10	26.c	25.c
15	No Recording.	No Recording.
20	No Recording.	No Recording.
25	No Recording.	No Recording.
30	No Recording.	No Recording.
35	No Recording.	No Recording.
40	28.c	38.c

Conclusion:

The normal bottle of water didn't get as hot as the CO2 water. This is just the same as climate change. I also found this experiment interesting.
