SPACE BAG

Question: What happens inside the bag when you create an ACID-BASED reaction?

The two chemicals work together to create a gas (carbon dioxide) which starts to fill the bag.

Hypothesis:  We think it will create too much carbon dioxide and fill up the bag with gas.
Questions to explore:
1. Will different temperature water affect how fast the bag inflates?
2. What amount of baking soda creates the best reaction?
3. Which size bag would create an explosion?

Our Experiment

Materials: 

sandwich bags
baking soda
warm water
vinegar
measuring cups and spoons
facial tissue

---

Safety Procedures

Procedure:

1. Add 1/4 warm water into the bag.
2. Add 1/2 cup of vindgar to the water in the bag.
3. Put 3-teaspoons of baking soda into the middle of
the tissue and make a tight packet.
4. Quickly unzip the bag and zip it back to see the chemical reaction.




Special Needs:
Disposal of water created substance

The Science behind it

Two chemicals work together to create a gas (Carbon Dioxide).

Conclusions
By creating a chemical reaction we were able to manufacture Carbon Dioxide within the bag, so we called our experiment the "Space Bag"
On Earth, plants remove carbon dioxide through the process of photosynthesis. The plants take in carbon dioxide and release oxygen. However, in a spacecraft, carbon dioxide must be removed from the cabin air through chemical processes. Most spacecraft rely solely on removing the carbon dioxide with canisters that contain powdered lithium hydroxide. When air containing carbon dioxide (CO2) gets passed through the canister, it combines with the lithium hydroxide (LiOH) to form lithium carbonate (Li2CO3) and water (H2O).
