Capillary Action Science Report

 Hello Bloggers, 

For literacy, we have been learning about capillary action. We had to conduct an experiment where we would try 3 different liquids with food colouring in it and then see how far up the liquid would go up the veins. Here is my report and see ya.

Capillary Action

Questions:

• To the plants take in the water straight away when it comes into contact or does it wait

• How do the plants take in the vitamin d from the sun

Research Summary:

Capillary action is very interesting as we use straws to suck water or whatever up, plants do pretty much the same thing. The plants use cohesion as it can make the water go up when you would think that gravity would be pulling it down. 

Adhesion is when something is the ability to stick to something and choose how sticky it is. With adhesion, a water molecule is trying to get up a wall, and it needs the other particle to get up that wall as the molecules are stronger together. 

Surface tension it the other word in capillary action. If you see a leaf floating on the water, and you push the edge down, the whole leaf completely sinks, and the leaf is no longer floating on the water.

Hypothesis

I think that the coloured water will go up the celery stalk faster than the other liquids eg: white vinegar and sprite (lemonade).

Materials:

• Beakers

• Food Colouring

• Sprite

• White Vinegar

• Water

Procedure:

1. Colour the liquids with food colouring in your measuring beaker

2. Set a 2-minute timer and place the celery into the water

3. Once the timer has finished, record the height of the coloured veins and also record what colour the veins are. Repeat this sequence two more times so the total time is 6 minutes

4. After 6-minutes, chop the end of the celery that has not been in the liquid and chop it until you see colour

5. Measure the final vein and record your results

Observations/Results:

Climbing	2 Minutes	4 Minutes	6 Minutes	Colour	2 Minutes	4 Minutes	6 Minutes
Water Climb	0.5cm	1cm	3.5cm	Water Colour	Red	Red	Red
Vinegar Climb	1cm	1cm	1cm	Vinegar Colour	Red	Red	Red
Sprite Climb	2cm	1cm	1cm	Sprite Colour	Red	Red	Red

Discussion:

For the sprite experiment, the sprite did not climb up the veins very far as that porous. It only went up a couple of centimetres. It was very cool though to see it come up the veins. 

For the 2nd liquid, the water went way better as the results beat all of the others and came up that veins way higher than the other liquids. I think the reason why the water was better because it is more natural than the sprite. 

The vinegar experiment went pretty well even though the vinegar tasted terrible. It climbed not very high but it looked way cooler than all of the others.

Conclusion:

In conclusion, it didn’t turn out as I expected but it was still pretty cool when it climbed up the celery veins. Maybe next time we could use paper and see how high that climbs.
