Predicting/Hypothesizing We predict (make hypotheses) when we make a forecast about what will happen in the future. The prediction is based on what you already know and data that you have collected. Make observations and measurements (collect data) Look for patterns in what you have observed Make a prediction based on what you know Test your prediction to see if you are right Make a new prediction if you are wrong (Prediction) tell what will happen next. – Example: The Clemson Tigers will win their next football game. Science Investigation A fair test is one in which only one variable is changed or tested. A independent (manipulative) variable is the one factor that is changed or tested by the student doing the investigation. Always put it on the x-axis. This is what is changed on purpose by the investigator. in independent variable is what change. Think: “I” “I” A dependent (responding) variable is the result of the changing of the manipulated variable. Always put it on the y-axis. Think: in dependent variable on what change. “D” “depends” “I” stay the same or unchanged during the investigation. Controlled variables Steps to an Investigation Question Ask a question that can be tested. – Research - the topic Prediction What do you predict will happen? – Materials and Procedure Design Your Experiment – Record and Organize Data graphs, table, charts. – Explain Results– What happened? Compare the results to your prediction. Example of an Investigation Sam sets up an investigation to find out how sunlight affects plant growth. He gives 2 plants the same amount of water each day, but he places one plant in the sunlight, and the other plant in the shade. The plant in the sunshine grows 5 cm taller than the plant in the shade during the 2 weeks of the investigation. The Independent Variable is the location of the plants. The Dependent Variable is the height of the plants. The Controlled Variables include the type of plants and the amount of water. Variable Song Independent Variables are ones you change Independent Variables are ones you change. Dependent ones you measure Get it wrong you’ll feel displeasure Independent variables are ones you change. Independent variables go on the x axis. Independent variables go on the x axis. Dependent ones go high,
