How To Do A Science Project
Purpose • In-depth research • Learn the scientific processes (Scientific Method) • Solve Problems • Apply mathematical, writing, and communication skills
Experiments • Project diary • Research Question • Science Content Statement • Variables • Experiment Design • Data Chart • Graph • Results Statement • Conclusion • Real World Application • Reflection
Choosing a Topic • Pick something you are interested in!! (Hobbies, sports, health, etc.). http://www.all-science-fair-projects.com/category0.html • T-Charts will help you think of ideas you can research about your topic.
T-Charts Cars • Changes • The body shape • The weight • The length • The size of tires • Height of ramp • Results • Car speed • Distance car travels off of a ramp • Force needed to pull
Change • Kind of soil • Direction of light • Amount of water • Amount of light • Kind of water • Fertilizer ingredients • Results • Height of plant growth • Direction plant grows • Number of leaves • Number of flowers Plants
Research Question • The question should read: • Does (x) have an effect on (y)? OR • What is the effect of (x) on (y)? OR • If I change (x) will it effect (y)?
Question What is the effect of the height of a ramp (3.5cm, 7.0cm, and 10.5cm high) on the distance a “Hot Wheels” car will travel in centimeters from the bottom end of the ramp?
Science Content • Research: Important facts about the topic. • Use scientific words. • Use own words. No downloads. • Answer the 3 questions: • What is your reason for doing this experiment? • What do you already know about his subject? (FACTS ONLY!) • What information did you get from your research?
Variables Manipulated Variable: (x) The ONE Responding Variable: (y) The height of the ramp – 3.5cm, 7.0cm, 10.5cm The distance the car travels in centimeters from the bottom of the ramp to the back wheels of the car.
Predictions • The height of the ramp will have no effect on the distance the car will roll. • The higher the ramp, the farther the car will roll. • The higher the ramp, the shorter distance the car will roll. List all possible results
Hypothesis • The prediction you think will be the result and why. I think that the car will roll farther when the ramp is raised higher because I know that my bicycle and wagon go faster when I ride down a hill or down the steepest part of my driveway.
Constant Variable (Set up conditions) • The same car will be used in order to keep the weight and wheel conditions constant. • The same ramp to keep the length and surface constant. • The starting position of the car will remain the same. • The location in which the experiment is conducted will remain the same.
Materials List • Each material with description of number, size, amount, kind, and how each is used. Use metrics. • (1)Hot Wheels Car • (3)Blocks of wood (3.5cm thick) • Meter Stick • Ramp (100cm long)
Step-by-Step Directions Detailed directions that another person should be able to use to do your project the same way that you did it and get similar results. • Gather all materials together. • Select a smooth rolling surface to roll the car on (counter, table, floor). • Place one of the 3.5cm blocks at end of the ramp. • Place one end of the ramp on top of the 3.5cm block and aim the bottom toward the end of the rolling area.
Place the “0” end of the meter stick at the bottom end of the ramp. • Place the rear wheels of the car at the top of the ramp and release it to roll down the ramp. • Measure the distance it rolled from the end of the ramp to the back wheels and write distance on data chart. • Do this 10 times. • Place one of the 3.5cm blocks on top of the other 3.5cm block creating a height of 7cm. • Follow steps 4-8. • Place the third 3.5cm block on top of the other two blocks making height of 10.5cm. • Follow steps 4-8. • Find the mean (average) of distance recorded.
Data Chart Distance the car rolls in centimeters Height of ramp T1 T2 T3 T4 T5 Avg. 3.5cm 7.0cm 10.5cm 89 91 94 92 91 91.4
Bar Graphhttp://nces.ed.gov/nceskids/index.asp Distance in cm
Results • Describe what happened in the experiment using the data from your chart. The data shows that the car rolls almost twice as far each time the ramp height is raised. The average distance at 2cm high was 22.5cm, at 4cm high it traveled 43.2cm, and at 6cm high it averaged 91.4cm.
Conclusion • This statement tells why the results happened in your experiment • Discuss how your results compared to your predictions. The results supported my hypothesis. The higher you raise the ramp, the faster and farther the car travels.
Real World Uses • This statement explains who in the real world might use this information, ways they might use it, when, where, why, or how they might use this information. List at least 3 ways if possible.
Reflection • How I liked doing the project. • What would I do differently. • What new questions did this project present?
