• Lighter

• Water

• Gas

• Tray

• Hose

• Safety glasses

Instructions:

1. Get the equipment ready
2. fill the tray with water
3. squirt the liquid soap into the water and mix it
4. connect the hose to the gas tap
5. turn the gas on
6. make bubbles of gas
7. wear your safety glasses
8. wet your hands and arms with water
9. scoop the bubbles with both hands from the tray
10. hold the bubbles as far as you can from your face
11. the teacher is then gonna light the bubbles on fire in your hands!
12.  Don't PANIC!!, and slowly open your hands

   results:

 Safety in the Laboratory - Mr. Stock

1. Liquids do not go into the bins, because they could leak out of the bin and can make a stinky smell.

2. Solids do not go down the sink, it can block the sink and make a flood.

3. Wear safety glasses when you do experiments because chemicals, flames, or glass can go into your eyes.

4. Put your chair under your desk, and stand on the bench when you do experiments because people could be holding chemicals and they could trip and spill the chemicals everywhere.

5. Bags do not go on the desk, because heaps of animals have been dissected on that table, and the animal's germs can go onto your bag that you carry around everywhere.

6. Long hair should be tied back because if there's a fire in your experiment your hair could get caught in the fire and it will burn it.

7. Do not smell the chemicals, because they could get into your stomach and you could pass out.

8. Walk don't run around the room, because you could trip up and spill your chemicals.

9. Do not eat or drink in the lab, because you could poison yourself after dissecting an animal.

Gummy Bear osmosis

 Aim:

I want to find out what happens when gummy bears are put in liquids.

Method:

Equipment:
. Salt Water (Sodium Chloride)
. Normal Water
. Sugar Water (sucrose)
. Gummy Bears
. 2x Petri dishes
. Marker pen
.Electronic Scales

Instructions:

1. Get your equipment

2. Wear safety glasses

3. Using a marker pen, write your name and the conditions and the weight of the gummy bear.

4. Do the experiment

Results:

	Dry Gummy	Sugar Gummy	Salt Gummy	Water Gummy
Initial Weight (g)	2.03	2.16	2.13	2.08
Final Weight (g)	2.13	4.53	4.27	8.4
Difference	Gain 0.10g	Gain 2.37g	Gain 2.14g	Gain 6.32g

The water gained the most weight.

Why? since there are tiny holes outside of the gummer bear, the small holes are only small enough to let all the water molecules inside the gummy bear, but the sugar/salt molecules are not small enough to be let inside the gummer bear.

Edible Slime

Aim:

I want to find out how to make edible slime without getting poisoned.

Research:

Method:

Equipment:

Gummy bear

Powdered sugar

Microwave

Spoon/Spatula

Glass Bowl

Instructions:

1. Remove the wrapper from all of the lollie's that were in the packet.

2. Pick all of the lollie's up and put them inside the bowl.

3. open the microwave by pushing the lower button and then place the bowl on the microwave plate, then by using your hands, close the microwave door until it makes a shut noise.

4. then if the microwave is not plugged in or switched on, switch it on or plug it in, and when the microwave is on, press the button's 3 then 0 then start, then the microwave's light should turn on and it should make a sound, and your bowl should be spinning around.

6. Then when the microwave makes a beeping sound, open the microwave like how you did in step 3, then use your hands to pick up the bowl from the sides of the bowl, and place it on the table you were working on.

7. Now that your lollie's are melted, pick up the spoon you had chosen, then use that spoon to mix your melted lollies around, by using your hand and moving your hand in a circular motion.

8. Then with the icing sugar that the teacher has provided with you, Open up the packet at the top of the packet and get 2 cups of icing sugar, and gently pour it into the bowl where your lollies are.

8. Then using your hands, kneed the lollie and icing sugar together until your lollies don't stick to your hand anymore.

9. Then using your hands and Mouth, grab your Edible slime, open your mouth, and put the edible slime in your mouth, and use your top and bottom teeth to grab some of the slime, and eat it, then swallow it, and that is what you call EATING!!.

Aim:

I want to find out what happens when you put skittles in water

Method:

Equipment: 

• 8x Skittles
• warm water
• Petri dish
• Beaker
• Paper towel

Instruction:

1. Get your equipment
2. Put the skittles into the petri dish
3. Spread them out, around the sides
4. Clean and dry the beaker
5. GENTLY pour the water in the middle of the petri dish so that it is half full
6. Observe what happens

Describe what happens?

What happened was when I GENTLY poured the warm water in the center of the petri dish, when it touched the skittles the skittle lost color and got into the water, when the all the colors got into the water, they moved to the center of the petri dish making a rainbow.,

Why did it move the way it did?

The Skittles moved the way it did because when the sugar dissolved, the sugar is pushed outwards into the water which sends the colored water outwards as well
