CLASSIFICATION STATION (Observe, Compare, Measure, and Classify) Sort (Classify) your objects three different ways. Give each group a name. Use at least 3 different criteria to sort. For ex. metal, plastic, wood. 1st Sort 2nd Sort CLASSIFICATION STATION (Observe, Compare, Measure, and Classify) Sort (Classify) your objects three different ways. Give each group a name. 3rd Sort MARBLE PREDICTION (Predict, Gather Data, Record Data, and Display Data) Draw 1 marble out of the bag 10 times. Place it back in the bag every time. Record data using tally marks. Repeat 4 times. You have in your bag: Black 1, Blue 4, Green 6, Yellow 8, Clear 10 Make a prediction: What color marble will be drawn more times? _____________________ Frequency Table (Gather and Record Data) # of Trials Black Blue Green Yellow Clear Trial 1 Trial 2 Trial 3 Trial 4 Mean (Average) Add all trials and divide by the # of trials. Copy the other people’s findings in your group so you have all the data. Create a bar graph using the average data you just collected on the empty space provided. (See example on the back) Food Coloring and Filter Paper Experiment (Hypothesis, Conduct an Experiment, Infer, Identify and control variables) Controlled Variables 2 T. water Distance dots are apart 15 drops of food coloring Filter paper is the same size and kind Size of dots used Use time set for 2 minutes to let the color soak into the filter paper Make a hypothesis: What happens when we put food coloring on filter paper? ___________________________________________________________________________________ ___________________________________________________________________________________ 1. Use the 3 drawn dots on the pie pan that are far apart. 2. Fill each dot with watered food coloring. (yellow, blue, red) Be very careful not to get out of the dot. It must be in the dot. 3. Slide a piece of filter paper onto food coloring. (Barely touch the liquid) 4. Wait 2 minutes before picking it up. What happens when we put food coloring on filter paper? ___________________________________________________________________________________ ___________________________________________________________________________________ __________________________________________________________________________________ 5. What do the colors look like? Are they separated or are they blended all together? ___________________________________________________________________________________ ___________________________________________________________________________________ 6. In the second experiment most of the variables remained constant. One variable changed. What was the changed variable or independent variable? ___________________________________________________________________________________ ___________________________________________________________________________________ 7. Look at the list of controlled variables. What were the variables that stayed the same or constant?___________________________________________________________________________ ___________________________________________________________________________________ ___________________________________________________________________________________ 8. What was the result or dependent variable when the variable was changed from experiment 1 to 2? Did the colors look different? How did they change?____________________________________________________________________________ ___________________________________________________________________________________ ___________________________________________________________________________________ NOTES BEFORE EXPERIMENT DAY 5. TLW identify skills that scientists use (10) - Observe- Use your senses - Classify- putting things in groups - Compare- look at shape, size, color - Predict - Measure 6. TLW identify the parts of the scientific method. (50) - ASK A QUESTION - MAKE OBSERVATIONS - CREATE A HYPOTHESIS -Hypothesis: An educated guess based on what you know and what you observe. - Something you want to prove. - Can be changed - EXPERIMENT OR TEST THE HYPOTHESIS -Experiment: when you test your hypothesis 7. TLW identify the independent, dependent, controlled variables in an experiment. (14 ) - Variables- Factors that can be changed in an experiment - Independent variable- variable that is changed in an experiment - Dependent variable- changes as a result of a change in the independent variable - Constants- The variables that are not changed in an Experiment - Control the Variable: Control the conditions of the experiment - DATA - Gather data: when you collect information - Record data: write information down (note taking) - Display data: put data on a chart or graph - CONCLUSIONS - Infer: Draw a conclusion based on what you observe - Explains the results of your experiment NOTES BEFORE EXPERIMENT DAY 5.
