Elementary Science Fair

Cabrillo Point Academy

We would like to thank all of the students who participated in the 2021 Cabrillo Point Academy Elementary Science Fair! Our participants ranged in grades from TK to 5th and were challenged with using the scientific method as outlined in the following steps:

1. Gather information and observe (research).

2. Make a hypothesis (guess the answer).

3. Experiment and test your hypothesis.

4. Examine and analyze your results.

5. Communicate your experiment and results.

All of our participants did an excellent job and provided us with some truly remarkable projects! View their amazing projects below!

Student Projects

Josiah - 1st Grade

Dissolve Skittles - What happens to Skittles in different liquids?

"Hypothesis: I think everything you put on the Skittles will dissolve the Skittles.

Conclusion: Everything dissolved the Skittles. Rubbing alcohol just dissolves the Skittles a little. Water and vinegar completely dissolve the Skittles. "

Which burns longest? Making candles and measuring burn rates for three different waxes.

"Everything else being equal, the denser the wax, the longer the candle burns. Thus, burn rate is correlated with density and, in this sense, beeswax is king! Or should I say, queen : )"

Glow Lab

"Using 3 chemical solutions, example, zinc sulfide mixed with florescent and water, creates a chemiluminescence which creates a glowing solution without the sunlight. I mixed 2 other chemicals which were sodium bicarbonate, and sodium carbonate and Luminoil which turned the glowing solution the colors blue then green. I created a phosphorescence solution which is similar to the chemiluminscence solution which glowed without the heat of the sun and lasted longer then the chemiluminscence solution with a U V light."

What cleans pennies best?

"Hypothesis: I thought Coke was first and the vinegar was the second best. I thought coke was going to be the best because it has a lot of acid in it.

Conclusions Barkeepers Friend is the best because it cleans really good- they are shiny and it is fast. Vinegar made them clean but ruined the penny. Coke and Ketchup were kinda the same."

Trick or Tree

“How do we measure a tree that is taller than we are? New Prediction: 11 feet tall Plan: Stand Facing tree, turn around, put head between legs and with straight legs, look towards the top of tree. Walk away from tree a little more and try again until you can see the top of the tree (from view between legs). Mark the spot on the ground and measure the distance between the ground to the trunk of tree. (Creating roughly a 90 degree angle Triangle) Conclusion: Tree is 15 feet tall"

Cheng-Hsun - 3rd Grade

Soil Battery: How to Turn Produce into Soil Power (Cheng-Hsun had 3 hypothesis! We are only presenting one here).

"I was curious about wether different kinds of soil affect voltage and would different numbers of plants affect voltage. Due to density, I think that silt soil will have the highest voltage. Sandy soil will have the second-highest voltage, and peat soil will have the least voltage."

"My first hypothesis is that silt soil will have the highest voltage; the second

highest in Sandy soil. Sandy soil will have a higher voltage than Peat soil. I think Silt

is the highest because of its density and what it’s made from. The result was sandy

being the highest, silt is second and peat is last. According to the results, it is

different from the hypothesis. I think that maybe sand has more organic matter than silt at the beginning."

Hudson - 2nd Grade

All about Electrolytes and experiment: what liquids are electrolytes.

"My hypothesis was that liquids that contain water were electrolytes. My conclusion was that not all types of water or liquids that contain water are considered electrolytes What I have learned is that all solutions can be mix with distilled water ONLY in order for the results to be accurate."

Adam - 1st Grade

My Catapult - How Far Will the Objects Fly?

"Adam hypothesized that the lighter the object, the farther it would fly. He concluded that the lighter objects went farther, but the shape of the object also had an effect on the distance."

Cyrus - 4th Grade

The Wave Machine: Measuring Amplitude

"Cyrus stated his hypothesis. The more energy exerted, the more the height of the wave (amplitude) would increase.

Conclusion: The hypothesis was correct. He tabulated the measurements for three different energy taps and recorded them in his data table."

Hawwa & Husna (Twin Sisters) - Kindergarten

Do liquids expand when frozen?

"They believed the juice will be the only liquid that will expand when frozen while the other liquids will not expand when frozen. Their conclusion was that all liquids except for salt water froze and expanded. They learned that most liquids freeze when in the freezer and will expand."

Rebecca - 4th Grade

How does the use of electronic media affect the tolerance of pain?

"Rebecca researched if using video games and television as a distraction during painful stimuli reduced pain for participants in her experiment."

"I thought that the activity the person liked best would let them tolerate pain the longest. I found that most people could last longer with television. Several subjects reported that it was too hard to concentrate on the video game. Some subjects reported that the trials got easier as they went on because their feet got used to the cold and it wasn’t as shocking. We tested no distractions first, video games second, and tv last. My data showed that all but one person did best watching television."

Mix Colors With your Eyes

"Does colored water change colors when light hits it? Hypothesis: blue water changes to yellow when light hits it, yellow water does not change color when light hits it, and red water does change to orange when light hits it. Conclusion: Blue water remains the same when light hits it, yellow water changes to green when light hits it, and red water changes to orange when light hits it."

Number 1 Glue Stick! - To compare Elmers Glue Stick with Bazic Glue Stick

"The project was to compare glue sticks. George had predicted that the two glue sticks would be the same. George glued a variety of objects using each glue. The Elmers glue stick held much better holding all the tested items in place while the Bazic glue stick did not hold the beads after the glue dried. George recorded his details and based on his results he has decided Elmers glue stick is proven to be the stronger glue stick of the two."

Abigail - TK

Which boat can hold the most pennies?

"Hypothesis: She thought the biggest, widest boat would hold the most pennies.

Conclusion: She was right! The biggest, widest boat held the most pennies. The most narrow boat, the canoe, held the least amount of pennies. What she learned: The wider the area of the boat displaces more water beneath the boat, so it can hold more pennies."

Everett - 4th Grade

Which surface absorbs the least kinetic energy?

"I think that the tile would absorb the least kinetic energy. I think this because it is loud when you bounce the ball and it is harder than other surfaces.

The tile absorbed the least kinetic energy. I know this because the ball bounced higher than all the other surfaces"

Seeing if radish seeds grow in different materials

"Hypothesis: Radish seeds will sprout differently in different materials. Specifically, moist soil, and moist cotton ball are expected to grow best. Seeds will possibly grow in sunflower oil, olive oil and water. Seeds not expected to grow in air or dry soil.

Result: Water, moist soil and moist cotton ball all sprouted well in one week. Air (control), sunflower oil, olive oil, vinegar, and dry soil did not grow. Light seeds floated on the liquids, but the heavy seeds did not. Conclusion: water is necessary for sprouting of radish seeds. Learned: soil is not one of the needs for sprouting"

"Growing Crystals" Growing crystals with Ammonium Phosphate

"Hypothesis: I think it will turn into crystal form by day 5. Conclusion: Crystal didn't form it may need more time and maybe some sun to dry up the liquid. Learned: I learned that you when you mix things together it causes a chemical reaction. Also, that things can change from liquid to solid form."

Jillian - Kindergarten

Bristlebot - Which is faster the flat-wide bristlebot or the angular (wavy) bristlebot?

"Jillian thought that the flat-wide bristlebot will move faster than the angular (wavy) bristlebot. After five races, the flat-wide bristlebot wins three (3) times over the angular (wavy) bristlebot. She found out that the bristles affect the movement of the bot, and because the flat-wide bristlebot has a better hold on the surface, it moves faster than the angular (wavy) bristlebot."

What conducts electricity?

"Hypothesis: Metals and liquid conduct electricity. Analysis and Conclusion: Most metals and most liquids conduct electricity. Most living things are made of some kind of liquid. Therefore, they can conduct electricity when you test the part with the most liquid. The only metal that didn't conduct was the one touching something that couldn't conduct-rubber."

Tyler - 1st Grade

Test Track: The Science of Superspeed- How does the type of surface material on the ramp affect the speed of the toy car?

"Student thought the yoga mat would be the fastest, however the plain wood was the fastest. He learned that the more friction the slower the car can go and the less friction the faster it would go."

The Filtering

"Question: How do we get clean water? Prediction: I can make a filter to clean muddy water enough to drink. Plan: Layer coffee filter, sand, rocks, sand, rocks, and crushed leaves into contained (water bottle). Pour muddy water into filter container and use a cup to collect “filtered water”. Results: Water went in muddy and came out less muddy. Conclusion: This water is not clean enough. I would not drink it. Maybe if I was stranded, I would boil it next if I really needed water. Yea, I’d still boil it. There might be some kind of germs in there."
