part 2/2

1. I can write a conclusion based upon the results of my experiment
2. i can design and conduct an experiment
3. i can write a report and check it with the marking sheet
4. i can draw a table and graph for my results

Which materials did I use for this experiment?

Background information

In this experiment you will find out what is of influence on the germination of cress seeds. 

First watch a video of the CONTROL experiment: the normal situation. 

Pay attention: there will be some questions after.... 

Control experiment

https://youtu.be/bUcqU3SZyDI

How many seeds did I use in this experiment?

Why do I also check the temperature?

What will you investigate?

Now we have seen the normal situation, you can change 1 thing. 

For example: use a different type of seeds:

hint

Will tomato seeds germinate faster than cress seeds? 

Instead of cotton wool you could use...

or replace water with....

Hint

Will cress seeds germinate slower, when I use cat litterbox filling instead of cotton wool? 

hint

will cress seeds germinate faster when I replace water with lemon juice?

Start experiment

• Collect materials
• Conduct experiment 
• Clean up 

• Create table to collect results
  

hint

Copy the table and add a row for your own results 

Results

1. Fill in table
   
2. Draw graph or bar chart
   

Example table: results control group

Conclusion

1. What was the question?
   
2. What were the results of your experiment?
   
3. Was your hypothesis right?
   

Checklist 

Problem definition

Is it a logical question?

Is there only 1 difference with the control group? 

Hypothesis

Did you use:

If...... then..... 

for example: 

If I replace water with lemon juice, then my seeds will germinate faster

Materials

Are all materials listed, and how much / many? 

Experiment

Explain exactly what you did? 

Results : table

a table with: 

quantities and units 

control group results

results of your test

Results: Graph

Quantities and units on X- axes and Y-axes

2 lines : control group and your test results

Conclusion

Answer the question: 

What were the results of your experiment?

Was your hypothesis right?
