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

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? _____________________

(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

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?

What was the changed variable or independent variable?

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
