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:

3.water, colored markers, a zip-lock bag
4. 1.Draw the water cycle on the bag with the markers. 2.make sure to label the processes of evaporation going up, condensation at the top and precipitation coming down. 3.Put your bag in the freezer for the water to freeze 5.Once frozen hang your on the window in a sunny area, and observe how the water changes from frozen to water vapor and falls back as water
5.Yes
6. This experiment demonstrate the the cycle of the water: evaporation, precipitation, runoff and the collection
Topic:chemical reactions
ResponderBorrarGroup:Maria Camila And Maria Angel
Materials:bottle,baking soda,Balloon.
Procedure
Take off the tap,and pour the vinegar into the bottle then,pour the baking soda into the bottle as well Once the baking soda is in,quickly put the mouth of the ballon over the bottle opening it might be helpful to practice putting the ballon on the bottle quickly before you do the actual experiment so you can get the hang of it
When you combine the baking soda an vinegar,the 2 chemicals undergo a chemical reaction.
A chemical reaction is when 2 chemical react to each other to form a new chemical or chemicals in this case the soda and vinegar combine to form water,some chemical called sodium acetate, and carbon dioxide.
The experiment we don't do it
what is a chemical reaction?
BorrarChemical reactions (also called chemical changes or chemical phenomena) are thermodynamic processes of transformation of matter. These reactions involve two or more substances (reactants or reagents), which change significantly in the process, and can consume or release energy to generate two or more substances called products.

ResponderBorrarHow to make coffee explaining the filtration
Elements
Powder coffee.
Sugar.
Strainer.
Water.
Recipient..
Kettle.
Stove.
Steps
Put coffee, sugar, and water in the kettle
Put the kettle with all those things on the stove
turn on the stove
Filter it in the strainer
Put the liquid on a recipient
How the filtración funtion?
Filtration occurs when a mixture between a liquid and a solid is separated by something, in this case the strainer, which allows the liquid to flow and traps the solid.
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.
