Science Experiments
Welcome to the Science entry of this Final Project Blog! 😎
In this entry we're going to detail several experiments related to this term's topics, such as: Changes in the state of matter, Pure substances and mixtures, Solutions, Methods to separate mixtures, chemical reactions, among others. You can redact the experiments as follows:
1. Topic:
2. Group:
3. Materials:
4. Procedure (Step-by-step):
5. Was the experiment done?: Yes/No
6. Explanation of the topic (What does this experiment demonstrate?):
Topic: Pure substance and mixture.
ResponderBorrarThe substance that cannot be separated into another by physical procedures is a pure substance. The substance that can be separated by chemical procedures into others is a compound. The substance whose components can be distinguished with the naked eye is a heterogeneous mixture.
EXPERIMENT STEPS:
We need this materials:
Oil, Water, salt, 2 cups and a spoon.
1.Take tone of the 2 cups.
2.Put some water into the cup.
3.Put some salt in the cup.
4.mix the 2 elements whit the spoon.
Now we have a homogenous substance.
why?
Well, because before pouring the salt into the water the water was a pure substance since it was not combined with anything but when we poured the salt the water became a mixed substance since it had been combined with the water and it was already combined with another components before pouring it into water.
2 EXPERIMENT STEPS:
We need the following materials:
Water, oil, the other cup and a spoon.
1.Take the other cup.
2. Put some water inside the cup.
3.Put oil into the cup.
4. Take the spoon and mix the 2 elements.
Now we have a heterogenous substance.
Why?
Well, because when we poured the water the water was a pure substance but then we poured the oil and we expected it to mix and make a homogeneous substance but what we created was a heterogeneous substance since when we poured the oil it did not combine with the water it only mixed. Left above it, the water remained a pure substance and so did the oil since they were not combined with each other.
CONCLUSION:
In conclusion we have learned that a pure substance is an element that has not been mixed with something else other than itself. We also learned that a mixed substance is two elements that when mixed do not come together and remain in their original state.

1. Topic: Methods to separate mixtures
ResponderBorrarThis experiment demonstrates the separation of immiscible liquids, such as water and oil, which do not mix with each other.
2. Group:
Victoria Ramírez y María Gabriela Romero
3. Materials:
- Water (about 100 ml)
- Cooking oil (50 ml)
- Beaker or transparent glass
- Spoon or pipette
4. Procedure (Step-by-step):
Fill a beaker halfway with water (about 100 ml).
Carefully pour about 50 ml of cooking oil over the water.
Observe how the oil floats on top of the water, forming a separate layer.
Let the mixture sit for a few minutes so the liquids fully separate.
Using a spoon or pipette, gently remove the oil from the top layer without mixing the liquids.
The water will remain at the bottom of the beaker, and the oil can be collected separately.
5. Was the experiment done?:
Yes.
6. Explanation of the topic (What does this experiment demonstrate?):
This experiment demonstrates decantation, a method for separating immiscible liquids, meaning liquids that do not mix. Water and oil have different densities, with the oil (less dense) floating on top of the water (denser). This principle can be applied to separate other mixtures of immiscible liquids, like oil and water spills.
Decantation is widely used in everyday life and in industry for separating liquid components, cleaning oil spills, or purifying water.
cool! I saw the visuals of the presentation in my mail, and it looks stunning too! Good Job!
BorrarTopic:The water cycle
ResponderBorrarBy:Maria Paula y Sebastian Quintero 5B
Materials:
Plastic wrap
A cup
A bowl
A ice cube
Hot water
Procedure
Step 1:Put the cup in the bowl
Step 2:Put the hot water in the bowl
Step 3:Put the plastic wrap around the bowl tightly
Step 4:Put the ice cube on the top right over the cup
Was the experiment done?
no (because as I write this we haven't done it)
What does this experiment demonstrate?
The experiment demonstrates how water cycles through different states—evaporation, condensation, and precipitation—in a closed system, similar to how it operates in the Earth's atmosphere.
How?
The warm water surrounding the cup heats up and turns into steam. This steam rises and travels to the cooler surface of the cup. The steam comes into contact with the cold surface of the cup, which is kept cold by the ice on top. The drop in temperature causes the steam to cool and condense into tiny water droplets inside the cup. The condensed water droplets collect in the cup and eventually fall back into the container due to gravity. This mimics the process of precipitation, where water condensed in the atmosphere falls to the ground. Water that falls back into the container can be warmed again, starting the cycle over again. This illustrates the continuous nature of the water cycle, where water moves through evaporation, condensation, and precipitation in a repeating process.
Ptt:It took me a long time to find this information, teacher, so I don't give me less than 85 because I tried very hard. Thanks
Great Job! I can tell you guys tried very hard, yes, I can't promise anything though haha
BorrarExperiment: Changes in the State of Matter
ResponderBorrarTopic: Changes in the State of Matter
Group: Solid to Liquid
Materials:
Ice cubes
A small cup or bowl
A spoon
A heat source (like a lamp or a hot water bath)
Procedure (Step-by-step):
Place the ice cubes into the small cup or bowl.
Observe the ice cubes in their solid state.
Use a heat source to warm the cup or bowl gently.
Watch the ice cubes as they begin to melt into liquid water.
Record the observations of the change from solid to liquid.
Was the experiment done?: Yes
Explanation of the topic: This experiment demonstrates the change in state from solid (ice) to liquid (water) when heat is applied. The ice melts because the heat energy causes the water molecules to move more freely, transitioning from a rigid solid structure to a flowing liquid state.

Explanation:
When you combinate baking soda an vinager the two chemical undergo a chemical reaction when the vinager combine it became Co² and inflates the balloon.
Topic:Methods to separate Mixtures
ResponderBorrarExperiment :filtration
By Luciana Cárdenas and Ivanna Sofía Díaz
Materials:
water
sand
funnel
filter paper and a beaker
Step 1:Mix the water and sand.
Step 2:Roll a piece of filter paper and put it on the funnel.
Step 3:Put the funnel on the top of the beaker.
Step 4:Pour the water with sand on the funnel.
Step 5:Wait until all the water has run through.
Was the experiment done?
Yes,it was done
What does this demonstrate?
This demonstrates how the parts from the water and sand aren’t completely dissolved or mixed with each other and it demonstrates the difference that is between the components that conformes the water and sand,also it shows a method which isn’t that complex and can be used easily with the correct materials to separate some types of mixtures.
1. Topic: Methods to Separate Mixtures through Evaporation
ResponderBorrar2. Group: José José Daza y Ana Lucía Barón.
3. Materials: Salt, Water, A small pot or pan, A stove, A spoon, A glass container.
4. Procedure (Step-by-step):
- First, we have to prepare the mixture by filling the glass container with water and stir in about two tablespoons of salt until it dissolves completely.
- Next, we heat the mixture by pouring the saltwater into the pot and place it on the stove.
- Then, we start the evaporation process by turning on the heat and letting the water simmer. Over time, the water will evaporate.
- Finally, we start observing the changes: As the water turns to vapor, you’ll notice the salt begins to reappear at the bottom of the pot. When all the water has evaporated, only salt will be left behind in the pot.
5. Was the experiment done?: Yes.
6. Explanation of the topic: Evaporation is a process where a liquid turns into vapor, leaving behind any solid materials that were dissolved in it. This method is useful for separating mixtures like saltwater, where the liquid (water) evaporates and the solid (salt) stays behind.
Materials:
ResponderBorrarA glass of water
A marker or tape
A sunny or warm place
Step 1: Prepare
Fill the glass halfway with water. Use the marker or tape to mark the water level on the glass. This way, you can see if the water goes down.
Step 2: Place the Glass
Put the glass in a place where it gets sunlight or is warm, like near a window. The heat helps the water evaporate faster.
Step 3: Observe
Each day, check the glass and see if the water level has gone down. That's because the water is evaporating, which means it's turning into gas and going into the air.
Step 4: Conclusion
After a few days, you'll see that the water keeps going down. That's evaporation! When water heats up, it changes from liquid to gas, rising into the air.
It's like what happens to puddles after it rains: when the sun comes out, the water disappears. It's the same idea!

Topic:Chemical reactions
ResponderBorrarMaterials: Backing soda, glass, vinager, soap and if you want colorant
Name of the experiment:The chemical"Explotion"
What is Chemical reaction?
Chemicals reactions are the process in which one or more subtances, the reactants, are converted to one or more different subteances, named the product. A chemical reaction rerranges the constituent atoms of the rectants to create different sunbtances as products.
STEP 1: Put in the half of the glass, vinager.
STEP 2: At 5 SPOONS of soap of whatever you have.
STEP 3: Them at the BANKING SODA in the vinager and soap.
STEP 4: Observed what happened.
Conclution: We can´t mix it we all things because vinegar is an acid called acetic acid that, when in contact with baking soda, generates a chemical reaction. Among the products of this chemical reaction is carbon dioxide, CO2, a gas.
THANKS
COOL! Good job, as a side note, it is spelled: BAKING* instead of backing, same goes for CONCLUSION* instead of conclution, overall it was a pretty good observation. :D
BorrarExperiment: Simulation of the cycle of water
ResponderBorrarMaterials for the water cycle model used:
1- Cardboard
2- Images (trees and mountains)
3- Wire
4- Adhesive tape
5- Silicone
6- Cotton
7- Plastic hose
8- Paint
9- Water bottle
10- Water
Step 1: We used cardboard as the base of the model and paint it blue. We put images of trees and mountains to create the landscape, pasting them with silicone. Also, we wrapped the cardboard with tape for water not to soak it.
Step 2: We used a plastic plate to represent a body of water where the collection happens.
Step 3: We placed a thin transparent hose over the model with holes in it and attached cotton along the length of the hose.
Step 4: We used a sun image on a skewer to represent the warming of the water to simulate evaporation. Later, as the water vapor rises and forms clouds, it would also represent condensation.
Step 5: At one end of the hose, we glued a bottle cap, which will connect to the water bottle. To start the water flowing through the hose, we have to press the bottle so that water drips through the holes and simulates precipitation.
Step 5: The water falls and collects again to begin the cycle again.
Conclusion: It was fun to build a model to simulate the cycle of water. Using simple materials like cardboard, plastic objects, cotton and water, we showed a real processes happening every day in the world, such as Evaporation, Condensation and Precipitation. This model makes the process easy to understand and we as students can use creativity for exploring more the science behind everyday natural events.

Topic: Chemical reactions
ResponderBorrarMaterials:
Empty soda bottle
Vinegar
Backing soda
a Balloon
STEP 1:Take off the cap.
STEP 2:Pour vinegar into Bottle.
STEP 3:Pour Backing Soda into Bottle
STEP 4:Put balloon on Bottle
Was the experiment done?
Yes,it was done
What does this demonstrate?
This shows that since baking soda and vinegar are chemical substances, it is shown that a chemical reaction occurs but performing the experiment, a gas called carbon dioxide is created. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas is created, the bigger the balloon will inflate.
