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

<a href="https://youtu.be/bUcqU3SZyDI ">https://youtu.be/bUcqU3SZyDI </a>

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?&nbsp;

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?&nbsp;

hint

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

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&nbsp;

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?<div>Is there only 1 difference with the control group?&nbsp;</div>

Hypothesis

Did you use:<div><br></div><div>If...... then.....&nbsp;</div><div><br></div><div>for example:&nbsp;</div><div><span style="font-weight: bold">If </span>I replace water with lemon juice, <span style="font-weight: bold">then </span>my seeds will germinate faster</div>

Materials

Are all materials listed, and how much / many?&nbsp;

Experiment

Explain exactly what you did?&nbsp;

Results : table

a table with:&nbsp;<div>quantities and units&nbsp;</div><div><br></div><div>control group results</div><div>results of your test</div>

Results: Graph
