WHICH WATER

PURPOSE

• Which type of water make plants grow faster and taller?
• Types of water: carbonated, sugar, salt, and tap water

BACKGROUND

• We found a experiment that was done and changed it to fit our experiment
• We also resarched the best types of plants to use: we used grass
• We also found websites that helped us with our experiment

HYPOTHESIS

• Megan: tap water will work the best
• Connor: carbonated water will work the best

MATERIALS

• Water
• SUgar
• Salt
• Seltzer
• Mesuring cup, containers, ruler, teaspoon, plastic cups

EXPERIMENTAL DESIGN

• We tested 4 kinds of water: salt, sugar, carbonated and tap
• We recorded how tall the plants grew and how much growth there was
• We obeserved the data once every week

DATA/OBSERVATIONS

• Week 1:
• Tap water - 1 and 1/2 inches
• Carbonated- 1 and 1/2 inches
• Sugar- 1 inch
• Salt- did not grow

DATA/ OBSERVATIONS

• Week 2:
• Tap- 2 and 1/2 inches
• Carbonated- 1 and 1/2 inches
• Sugar- 1 and 1/2 inches
• Salt- no growth

DATA/ OBSERVATIONS

• Week 3
• Tap- 4 inches
• Carbonated- 2 and 1/2 inches
• Sugar- 4 inches
• Salt- no growth

DATA

• Week 4:
• Carbonated- 5 and 3/4 inches
• Tap- 6 and 1/4 inches
• Sugar- 5 and 1/2 inches
• Salt- 1/2 inches

DATA/ OBSERVATIONS

• By Week 5:
• tap and carbonated water- 7 and 1/2 inches
• Sugar- 6 and1/2 inches
• Salt- 1 inch

CONCLUSION

• The tap and carbonated water worked the best
• The sugar water worked the 3rd best
• The salt water worked the worst
