Pendulum Variables  Tested Different Masses, Arm Length, and Drop Angle  Recorded time it took for twenty oscillation and one oscillations in seconds.  Information Home

Significant Figures Rules 1. All non zeros are significant. (ex. 535~3 significant figures) 2. “Sandwich Rule” ~ All zeros between non zeros are significant. (ex ~ 4 or ~ 4) 3. Zeros to the right of non zeros, to the right of a decimal are significant. (ex ~ “placeholders” ~ 5 or.4210 ~ 4) 4. Zero to the left of non zeros, to the right of the decimal are not significant. (ex ~ 3) 5. Zeros after non zeros left of the decimal are not significant. (ex ~ 2) Home

Significant Figures Addition and Subtraction 1. Round answer to coincide with the number that has the least amount of places after the decimal. Multiplication and Division 1. Round answer to match number with least amount of significant figures. (ex. 2.0 x 2.00 ~ 4.0) Home

Independent Project I  Daylight Savings Project  Researched Daylights Savings on the internet Home

Trebuchet Researched trebuchets Designed a trebuchet Built a trebuchet Tested our trebuchet Home

Mouse Trap Car Procedure: Each person built a mouse trap car using different materials. At the end of building we raced them. Materials: Mouse trap wood wheels steel rod fishing pole. Results: My first try without the fishing pole the car hardly moved. After I applied the fishing pole the car went 17 meters. Home

The Future of Hospitals Experiment included researching anything that will advance in the future. The requirements were to make a power point presentation and present it to the class. Everything inside the power point needed to be factual. I researched the future of Hospitals. The Future of Hospitals – Power Point Home

Independent Project II Color Vs. Word Experiment Sherry and I were partners, we tested color of the word vs. the word color, we tested students independently and timed them saying first the words and then the color of the words. Information Home

Bridge Building I We were put into groups to make a bridge of our own design out of balsa wood and super glue, with a weight limit. After everyone was done we tested them until they snapped in half. Home

Bridge Building II The second bridge building was the same as one but we looked for a new design that would be better than the last one. Home

Hot Air Balloon Everyone built the same hot air balloon with the same instructions. We used tissue paper and glue sticks. The launch was unsuccessful because there were many holes in the tissue paper from the glue sticks. Home

Independent Project III Sound Clarification Experiment Tested a few students to see if blindfolded they could clarify what was making the sound. Information Home

Independent Project IV Heart Rate Experiment Joel and I were partners we tested how long it takes people to get back to their normal heart rate after exercise. Information Graphs Home

Independent Project V Mr. Kravig gave each group one experiment Projectile Motion Vertical Projectile Motion and Hooke’s Law. Each group was to do the experiment then pass it off to another group until all groups had done the three experiments.Projectile Motion Vertical Projectile Motion Hooke’s Law Home

Vertical Projectile Motion We used a projectile and a ball bearing and at certain angles launched the ball five times and recorded the results. Information Graphs Home

Hooke’s Law Tested two different springs and different masses. Then we recorded results and founds percent error. Information Graphs Home

Projectile Motion Every group did this project we used a metal slope and a ball bearing we recorded the displacement of the ball on the carbon paper that was on the floor. Information Graphs Home
