**Teacher Comment:** An interesting choice of topic Dave. You were obviously interested in the topic, which is great. You have a clear aim but you haven't explained how you measured the height very clearly in your method. Excellent work with carrying out your experiment more than once to give you an average for your results but you haven't stated this on your science fair board! This means that hopefully your results will be more accurate. Great research done to help explain the science behind why the rocket shoots into the air, well done. Why do you have no graphs or tables to show your results? It would have been very easy to graph your results. Overall a good effort Dave, but it is missing a few things.

**Student Comment:** I had great fun doing this experiment and I learnt some knew things. I was nervous at first when I was presenting my science fair but once I had said some of my sentences I was not as nervous. I think that I need to improve on clear detail and having a logbook next time. I think that I did my design really well and that next time I will do my experiment more than two times to get accurate results.Thank you for the feedback next time I will have a graph if need be.

Science reflection

Today we went to the science lab & we had 25 experiments to try out. We did these experiments because it’s national science week this week. My favorite experiment was moving pins it was were you had to hold a knife upside down really tightly & put a hairpin on top of the blade part & then holding the hairpin so that it is just touching the table. I didn’t get around to one of the experiments & everyone said it was really cool.

__Friday 13th May__

Y esterday we went to the science lab and did a experiment. The experiment was what was the 5 different ingredients there was Cream of tartar, Icing sugar, Cornflour, Baking soda & Salt. our hypothesis was A: Icing sugar B: Salt C: Cornflour D: Baking soda E: Cream of tartar. The first one we tested was A: we got our cup & we put water in it then we put the A ingredients in the cup then we put our litmus paper in & nothing happened so we suggested that it was cornflour or salt. We then tested B: We got our cup & filled it with water then put the B ingredients in our cup & then we put our litmus paper in the cup & nothing happened. We then tested C: We got our cup again filled it up with water then put the C ingredients in the cup & we then put the litmus paper in the cup & the litmus paper turned blue. Then we tested D: again we got our cup, filled it with water, put the D ingredients in the cup & put the litmus paper in & the litmus paper turned blue.Then we tested E: we got our cup filled it with water put the E ingredients in the cup & it turned blueish black. When we finished we got 2/5 guesses correct. The answers we got wrong were A we thought it was Icing sugar but it was Cornflour, we also got C wrong we thought it was Cornflour but it was Baking soda & the other one we got wrong was D we thought it was Baking soda but we were wrong, the answer was Icing sugar. I really liked the science behind it because we get to actually do the experiment so it explains it better.

__WALT - Identify and group fingerprints into 3 main categories : arch, loop and whorl.__

AIM - To identify your own fingerprints out of an arch, loop and whorl.

HYPOTHESIS I think my finger prints on my left hand are Arches & my fingers on my right hand are Arches. I think this because when I look at my fingers they look like the shape of the arches.

EQUIPMENT Pencil, paper, sticky tape

METHOD

1. Rub the side of a pencil lead back & forth on a sheet of paper to build up the black area large enough to take ten prints. 2. Press one of your fingertips firmly onto the black. Place the sticky side of a piece of tape over your fingertip. ( You may need a friend to help you with this ) 3. tape the print to the correct location on the fingerprint form. 4.Using the magnifying glass compare your prints to the pictures below & try to label them as either Arches, Loops or Whorls.



Conclusion: When I did the test I found out that 8 of my fingers were arches & 2 of my fingers were whorls those 2 fingers were my thumbs.

These are my fingerprints
