Sustainability

Aim: I want to find out how to grow a sustainable garden. 

Research: 

I want to grow:

- Cabbage to be ready in November-December.

- Broccolli to be ready in November-December 

- Corn to be ready in November-December.

- Carrots to be ready in November-December.

- Lettuce to be ready in October-December. 

Self watering system: Sprinkling diaper crystals into the soil. The soil will slowly absorb the moist crystals, keeping the soil moist for the plants. 

Keeping pests away: Put ground coffee into the soil to keep slugs and cats away who hate it, put netting over the garden to protect the plants and put ladybugs in your garden. 

Method:

Equipment: 

Weeding/Gardening Tools

Seeds

Diapers + water

Scissors

String 

1m ruler 

Stakes

Instructions:

1. Mark out a 2x2 metre plot with string, stakes, and a ruler. 

2. Pull out all of the weeds and sow the soil around. 

3. Mix in your fertilizer, diaper crystals and coffee in with the soil .

4. Plant your seeds. 

5. Put the pest repellent contraption on your seeds. 

6. Add the self-watering system and finally, place a net across it. 

The Dirtiest place in the school?

Aim: To find the dirtiest place at HHS


Hypothesis: I think the Gym floor is the dirtiest place because lots of people go there to play around and they get all sweaty and then it drips every where.

Equipment: Cotton buds,Agar dishes, cellotape

Method: Take cotton bud and wipe it firmly over the surface, then wipe it across the agar jelly carefully. Seal the agar plate with cellotape and write the location on the tape. Store upside down in a dark location. 

The cleanest place was Mr stocks door handle because there was nothing on there.

The dirtiest place is the Gym floor because there was a whole agar was full of yellow.

I was surprised that Mr stocks door handle because he does experience.

The Rc laptop grew the most fungus 

The gym floor has the most bacteria 

Makeing Biltong (Beef jerky)

Aim: I want to find out how to make Biltong

Method:

• Meat
• 100ml brown sugar 
• 30ml coarse salt 
• 15ml bicarbonate soda (this softens the meat)
• 1 tbsp cracked black peppers 

Instructions

1. Slice the raw meat into 1-2cm wide 
2. Place the raw meat into a bowl
3. Then pour the salt and the spices then grab the raw meat and rub the salt and the [all over it NOT covering the hole thing
4. Tie the raw meat with the salt and spices with string at the end NOT THE MIDDLE.

Discussion: 

When I taste it, a explosion of salt in my mouth I made a funny face as I bite it.

Why did we salt the meat?

We salted the meat because salt dehydrate the meat so the mould and bacteria can't grow.

Growing Mold

Question>what causes bread to go off
Hypothesis>being left in the air, Being moist/damp/humid,being left in a warm place
Equipment>1/2 slice of bread sandwich  bag ( per slice) 1/2 a paper towel 10mls of water
method>

This was some bread I thought that was interesting 

what is the best condition for growing mold?

having it in the dark place and with air in the bag and water because the bread soaks up the water and having no light for then the sun will not get the bread hot. 

Mold is mold is kind of a good thing because penicillin is good for getting rid of bugs.

what is green mold? 

Science Badge Question 7

How does milk become yogurt 

Hypothesis> I think milk becomes yogurt because milk thickens if you add cream and mix it up then add fruit then put in the freezer. 

Materials> Milk,Yogurt (fresh plain)

Method> In a beaker add 150mls of trim milk and 2tsps of Acidophilus  yogurt.stir to mix. leave out over night.Repeat this for the cream and with trim(milk)

observation 
trim-When I looked at the trimed milk it looked normal it looked like milk ,With bubbles 
cream- When I looked at the cream Ihad a hard look at it and it was a light yellow 
blue- When I looked at the blue milk it looked flat ,No bubbles or anything

At what temp does bacteria?
What temp is a fridge?
What is the healthy temp of a human? 

The cream one looks like this 
The cream smells gross

The blue looks like this 

It smells like milk

And the trim looks like this 

It smells like yogurt 

What happened to change it 

The bacteria reproduced 

The bacteria fed off the sugar in the milk
The trim milk made a thinner type of yogurt than the others because it has less sugar. 

We let the milk stay out for 2 days and then placed the the beakers in the fridge. The results were not very good but it could change. 

If we got to do it again I would leave the milk in the fridge for longer.

Results:

this is my friends bottle because my bottle is not clear.











It smells like ginger beer and it smells nice

At first it tasted gross but then it tasted just like ginger beer it tasted really nice.

Discussion

What is yeast?  A microscopic fungus consisting of single oval cells that reproduce by budding, and capable of converting sugar into alcohol and carbon dioxide.

What did the yeast do in the Ginger Beer? The yeast grew from the sugar.

What are some other good uses of Yeast?

 Making bread 

What are some other bad uses of Yeast?

Having the yeast on you can cause infections 

What are some interesting questions that I would like to find 

out about this experiment?

Welcome to my very own blog for learning. I look forward to sharing my learning with teachers, my school, my family and friends anywhere.
