"Are sharpies actually permanent markers?"
Grade K-3
By: Nia-Loi Wright
Abstract:
The aim of this experiment was to find out which liquid: water, hydrogen peroxide, alcohol, soap or vinegar is better at removing black sharpie marks from fabric. Each liquid was placed on a piece of fabric with a black sharpie marker and the time it took for the colour to go away was written down. The experiment showed that the alcohol worked better than the other liquids I used. The one that did not work was the hydrogen peroxide.
"helium rocket"
Grade 4-6
By: George Waaler, Bodi Hodges
Abstract:
The objective of this project was to find out how many balloons a bottle needs to fly up.
I think it needs five balloons to fly up because a bott
le is very light so it will need not that many balloons on it. We have to get a plastic bottle. We have to find them. We blew up the helium in the balloons and with all the five balloons we had it was just like a parachute it did not lift off the ground but if we put it in the air I would take a while to fall back down to the floor. It fell to the ground way slower but it wasn't enough to make it fly.
"helium rocket"
Grade 4-6
By: Charlie Sanders, Rylan Smit
Abstract:
How would helium balloons affect the falling of an object?
The objective of this project was to determine how much slower an object would fall with helium balloons attached and without. We created a cardboard rocket with a cardboard box, tape, and scissors. We dropped it from a height of 5m without balloons 6 times. Then, with three helium balloons, we repeated the drop another 6 times, Then 4 balloons, then 5. Without balloons, it dropped the fastest. The more balloons we attached, the slower the object fell. Our project shows that the balloons had a force that defied gravity.
"drop timer"
Grade 4-6
By: Liam Miguel and Maximilian Knock
Abstract:
So our hypothesis is that the eraser would fall the slowest while the pencil is the second fastest and the softball is the fastest to drop. Our hypothesis was wrong because the eraser was the slowest while the pencil was the fastest. We did it 10 times for each object: pencil eraser softball and for our average time we divided those 3 by 10 because we did it 10 times. And our averages were: pencil: 74.5ms softball: 94.2ms eraser: 180.2ms. And we dropped the items from 164 inches. And here are our steps: Step 1: gather materials. Step 2: 2nd person goes upstairs. Step 3: a hypothesis. Step 4 the person upstairs drops the items while the person below times them. Step 5: observe and record data. Step 6: Write a conclusion from the data you collected. Step 7: present the project to the judges on Monday, March 13th.
"height of a daisy"
Grade 4-6
By: Isla Meyers and Evie Stanton
Abstract:
Does the amount of water affect how tall a Zinnia flower will grow? The purpose of this project was to see how tall a Zinnia flower will grow with different amounts of water, and which one would grow tallest. We believe that the Zinnia flower with less amount of water would grow tallest. In an egg carton, we planted 6 Zinnias and watered them with ¼ cup of rainwater for each Zinnia. For the other 6 Zinnias, we did the same thing but with ½ cup of water for each Zinnia. The Zinnia plants with less water grew tallest. We think that is because when we watered the plant with ½ cup of water, the seeds might have gotten out of their place because of too much water. This project showed us that too much water is never good And that it could drown the plant or move the seeds too low in the soil.
"investigate fungi"
Grade 4-6
By: Lily Carey, Ariella Adams, Justin Basson
Abstract:
Which different types of fruit rot within a week?
The purpose of our experiment is to find what conditions are best for mould to grow on different types of fruit.
Some of the fruit will be apples, bananas and oranges.
We believe that moist fruit will create more mold than dry bread
We place the fruit in a box dry.
We placed the same fruit in wet.
We will keep it for a week
We will take a photo of it every day and see which fruit grows fungus first.
"helium vs air"
Grade 4-6
By: Finley Hollingsworth, Luke Singh, Sekani Pemberton
Abstract:
Does the type of gas affect how far a balloon-powered car will go? The objective of this project was to see if a helium-powered car will change how far the balloon-powered car travels than an air-powered car. We thought the air-powered car would go farther than the helium-powered car. We thought the air balloon-powered car would go farther because the helium-powered car would just float in the air. We went to see which one went farther than the air balloon-powered car or the helium balloon-powered car. We went 3 times the first time the air balloon went farther than the helium balloon. The second time went it was a tie. The final time the air balloon-powered car went farther at 17 inches and the helium balloon-powered car went 15 inches.
"lettuce weight it"
Grade 4-6
By: Emily Jackson, Jemima Peliwan, Maryam Khan
Abstract:
Does the amount of water affect how a lettuce grows?
The purpose of this experiment was to find out if the amount of water affects the plant will grow or not. We had 3 plants with ½ cup water, ¼ cup water, and 1 cup water. We put the same amount of soil (1 cup) and put them in the same spot so that they can get an equal amount of sunlight. Our hypothesis was that the plant with ½ cup water would grow the most. However, the others would either be too much or too little. The results were that our hypothesis was correct. Although the plant with 1 cup of water did grow, it wasn't as healthy as the plant with 1⁄2 a cup of water.
"tomato experiment"
Grade 4-6
By: Danya Lettsome, Roshana Lewis, Florence Caulfield
Abstract:
How does salt water and soap water affect plant growth?
The purpose of the experiment was to find out if the salt and soap water would survive. We thought that the saltwater plant would die, the soap would be wilted but survive, and the freshwater would be the best plant. We used small plastic cups, soil, tomato seeds, liquid dish soap, table salt, and plastic teaspoons to water the plants equally. We first started with planting the seed, we then started watering the plants with fresh water so that we could see if they would continue to grow after they sprouted, after they sprouted we started watering them with soap and salt water, then we checked the salt plant after the first day and it was dead, we also noticed that a day after the soap and salt water plant died mildew grew. In the end, the soap and saltwater plants died.
"balloon powered car"
Grade 4-6
By: George Hollingsworth, Noah Anstock
Abstract:
Question: Does the friction of the different surfaces affect the speed of the balloon-powered car?
We hypothesized that on the carpet the balloon-powered car would go slower. We measured the length of where the car started to where it ended. The balloon-powered car consisted of lego wheels attached to straws at the bottom of the cardboard we added. On top of the cardboard, we added a water bottle. On top of the water bottle, we added another piece of cardboard. And on that piece of cardboard, we taped a balloon to it. And that's how we made the balloon-powered car. We tested on each surface three times and recorded the highest length. On a flat surface of vinyl tiles in class, it went about 2.4 feet. On a carpet, the balloon-powered car managed to reach approximately 1.5 feet. So that shows that the more friction the less distance the balloon-powered car goes. So our hypothesis was correct. So to answer our question, yes friction does affect the distance of the balloon-powered car.
"egg drop"
Grade 4-6
By: Moss Lang, Harrison Reid, Jake Richardson
Abstract:
Hello, my name is Moss, and my Experiment is an egg drop. Well, sort of, because our goal in this experiment is to prevent the egg from cracking when it Collides with the ground. So technically, this experiment is an egg protection experiment.
So let's start with our question, which is does the strength of the wind affect the drop speed of an egg?
So next we're going to talk about our hypothesis, which is that I and my team believe that the higher the wind speed, the egg will reduce velocity (speed) and it will reduce the impact so the egg won't crack. Next, we will talk about the materials. So in the project, we used a fan, a carton of eggs, a timer, a laptop, and a lot of paper. Now we're going to talk about the procedure, which is all the steps we followed in the experiment. First, we started building questions, then we made a hypothesis, after that, we drew a diagram, and then we made the poster, after that we recorded our information on the egg drop, which was egg-cellent! Next, we wrote our script.
Finally, we recorded our results, and our hypothesis was incorrect, so the fan failed to reduce the egg's velocity (airspeed).
"growth of beans"
Grade 4-6
By: Sophia Pade, Lily Graham, Maisy Sutherland-Pilch
Abstract:
Does the amount of water affect the growth of beans over 2 weeks? The objective of this experiment was to see if the amount of water will affect the growth of beans. We believe that the 3 TBS plant would grow the tallest because it has the average amount of water per week. When we started the experiment the plant with 6 TBS grew roots first and then the next day it sprouted to 4½ cm. We now think that the plant with 6 TBS will grow the tallest because it has the most water, and more nutrients to absorb.
"what evaporates more"
Grade 4-6
By: Eli Ghiorse, Tommy Bovio, Patrick Donovan
Abstract:
What is the evaporation rate of different liquids? The objective of this experiment is to find out which liquid evaporates more quickly.
We believe that the salt will evaporate quicker than the fresh water.
First, we collected two identical beakers and filled them with water to the same level. We added a spoonful of salt to one beaker. We angled both into the sun to start evaporating. We set a timer and check on the beakers at the same time over 5 hours. We check the level of millilitres of water in each beaker.
This project provided evidence of the rate of evaporation for both liquids.
"shooting shoes"
Grade 4-6
By: Saxton Stoutt, Ryan Lettsome, Nate Johnson
Abstract:
Our science fair project was about how different shoes affect your penalty shooting. The two different shoes are Nike sneakers and Soccer shoes. Our hypothesis is We think soccer boots will win because they are meant to play soccer and Nike sneakers are not meant to play soccer. The materials that we used were a goal, Soccer boots, a soccer field, and Nike sneakers. The difference between the two shoes is one is made for playing soccer and one is made for running. Also, soccer shoes have studs/cleats on the bottom to give you grip while the Nike sneakers don't have studs/cleats for grip. The Nike sneakers scored 20 and missed 10. The soccer shoes scored 18 and missed 12.
