Pulse/Heart rate TASK!

 So this is my teach class for the day. We were learning about Pulse/Heart rates. We had to do a series of things to see which gets the highest and the lowest rate. We did this is pairs and I was with Kiarah. One funny part was when Kiarah slipped trying to catch the ball. Anyways she was ok at the end. I hope I get to do this is the future. ENJOY! 

On the bottom is a photo of the watch we used to see our heart/pulse rate.

Carefully read and understand this recording and planning guide so you are systematic in scientific thinking, experimenting, recording and interpreting. 

Follow logically through each section so you are thorough in your science investigation steps. 

Complete each section with details needed so you have carefully logged your project...and so an outsider can know and understand too.

1	My science investigation TOPIC:  Pulse Rates
2	My investigation question Investigate the effect of different types of activity on the heart rate/pulse rate. 1.Which action/activity resulted in the highest heart rate?  2.Which action/activity resulted in the lowest heart rate? 3.Why do you think this might be? Hypothesis -I think running as fast as possible on the spot will have the highest heart/pulse rate. -I think that sitting down I would have the lowest pulse/heart rate.
3	Background research and knowledge I will explore as a backdrop to my investigation High blood pressure-120mmHg Low blood pressure-80 mmHg
4	Aim of my investigation
5	STEP 1 Put on the watch on tight so that your heart/pulse rate is correct STEP 2 Wait for your heart rate to go down STEP 3 Then you do the activities for 30 seconds and see if you heart/pulse rate goes up or down STEP 4 Write down the results  STEP X BOOM your done
6	My possible recording method Data collection table:  Name of the Activity Length of Activity Beat counted in 30 seconds Heart Rate mmHg Sitting 30 seconds 100/95 95mmHg Jogging on Spot 30 seconds 150/93 150mmHg Throwing and Catching ball 30 seconds 119/109 109mmHg Stretching 30 seconds 135/121 121mmHg Star Jumps 30 seconds 120/118 118mmHg Running as fast as possible on spot 30 seconds 119/160 160mmHg
7	Result:  1.Which action/activity resulted in the highest heart rate?    The activity that had my heart/pulse rate the highest was running 2.Which action/activity resulted in the lowest heart rate?    The activity that my heart/pulse rate the lowest was just sitting down 3.Why do you think this might be? I think that it happened because when you sit down you're relaxing your heart/pulse rate. When you're running it pumps it up.

Last session at TECH!

 Today was sadly my last session of the term with Mrs Sharmap. She does STEM and let me tell you this experiment was COOL! It seems pretty basic but the results are worth it. We got to see water travel through the stem in a plant. In other words Photosynthesis. Once we took out the plant and cut it open the insides were the colour of the water. I worked with Kamryn. By the way if you want to do this just look at the bottom. This experiment was really fun and actually was the BEST! I hope I get to do this again next term! I hope you learn something and that you ENJOY THIS!

Topic 7- Osmosis and Transpiration Photosynthesis-A process in which plants make their own food. C02+H20 Sunlight Sugar+02 (Carbon dioxide+water Sugar+Oxygen) Parts of a Plant  1.Flower 2.Stem 3.Leaf 4.Roots (Leaf is part of plant where photosynthesis takes place)

Stomata: Tiny parts that help water of Carbon Dioxide Osmosis: Process that help to move water from the roots to the leaves  Cells in the plants: Xylem and Phloem Phloem: helps food to move/distribute to different parts of plants

Celery and food colouring experiment: Purpose: To see water movement from the roots to the leafs through Xylem Supplies: Celery  Water  Food colouring  Cups (Conical Flask)  Scissors  Steps: Add food colour in water (10 colours in any order with any cups) 4 celery that have a lot of leafs  Cut off the end parts Put it in the Conical Flask Stir the water with the celery just to make sure that the colouring is in good Optional add plastic bags and a something to tie it with a twist tie  Wait and watch to see what happens  (1 hour 30 minutes then remove it or just as long as you want) Cut open your celery and take a closer look at the fibre where the Xylem is (There should be some colour there)  BOOM! They you have it
