STEM Activity: To programme a Bee-bot to move in the shape of a circle
- Investigating and experimenting
- Recording and communicating
- Rubber bands
What we did:
- We watched a fun video about the circle with a catchy song.
- Lorchán wrote the word ‘circle’ on the whiteboard.
- Each of us had a turn at drawing a circle on the whiteboard.
- We did a hunt around the classroom to find circular objects. We really enjoyed this.
- We sat at the group work table and read through our Bee-bot social story.
- Thomas ordered sandpaper numerals from 1-4 on the table and we looked at the 4 pieces of equipment which we needed for the experiment.
- We each took a turn at programming the Bee-bot to move in the shape of a circle by pressing the right arrow 4 times.
- Ciarán cleverly pointed out that we could also press the left arrow and it would still move in the shape of a circle.
- We watched the video about the circle again.
- We recapped Lesson 1 by looking at photographs on the interactive whiteboard which were taken during the lesson.
- We discussed how we could confirm our observations and prove that the Bee-bot can move in the shape of a circle.
- We observed Ms. Groarke attaching the marker to the Bee-bot with an elastic band.
- Each of us took a turn at programming the Bee-bot to move in the shape of a circle with the marker attached. We pressed the right arrow 4 times and ‘Go.’ Then we pressed the left arrow 4 times and ‘Go.’
- Sometimes we had to press ‘Go’ more than once and adjust the marker so that it left a more visible circle on paper.
- We labelled our work with lots of care as you can see.
- We watched the video about the circle one more time.
- We recapped Lessons 1 and 2 using photographs.
- We discussed if 2 or more Bee-bots could move in the shape of a circle at the same time.
- We agreed that that they could once we press the right/left arrow the same number of times and ‘Go’ at the same time.
- We prepared 2 Bee-bots by turning them on.
- We pressed the right arrow 4 times on both Bee-bots.
- We practiced pressing ‘Go’ on the 2 Bee-bots at the same time and observed them mostly moving in unison.
- After a few trials, we did it one last time and video recorded our results.
We hope you enjoy reading about our contribution to this year’s Science Exhibition!
Lorchán, Thomas, Ciarán, Seán and Akshay
Here are some examples of the children using technology. We have a wonderful computer room that we use to develop Power Points and plot graphs for STEM. We have interactive whiteboards in each classroom to enhance our teaching.
Siluan, Lorchán and Thomas spent Friday afternoon playing with Bee-Bots. They each had a Bee-Bot and a different activity mat. Siluan used the busy street map, Lorchán used the 2D shapes mat and Thomas used the letters mat. They are learning how to programme a Bee-Bot to move from one location to another using the directional arrows. They had lots of fun and are looking forward to using them again.
We investigated the respiratory system for the science exhibition.
First of all we learned how we breathe and the parts involved in the respiratory system.
We then carried out two experiments: How to Make a Model Set of Lungs and How to Measure Your Lung Capacity.
How To Make a Model Set of Lungs
A 2 litre bottle, 2 balloons, blue tack, a rubber glove, sellotape.
Step 1: First, cut a 2 litre bottle in half.
Step 2: Next, place a straw into a balloon and use sellotape to stick it on. Ensure that there is no air getting through. This will represent our trachea and our lung.
Step 3: Repeat step 2 as we have 2 lungs.
Step 4: Then, place the two lungs through the top of the bottle and secure using blue tack. Again, make sure that there is no air getting through.
Step 5: After that, place a rubber glove on the bottom part of the bottle.
Step 6: Finally, pull down on the rubber glove to show the air coming into the lungs and going out of the lungs.
What We Have Learned:
- The diaphragm moves down when we breathe in to make room for air in the lungs.
- The diaphragm moves up when we breathe out pushing out the air.
- The diaphragm is an important muscle in our breathing system.
How to Measure Your Lung Capacity
Permanent marker, 5 litre bottle, basin, plastic tubing
Step 1: First, using a permanent marker, mark off a 5 litre bottle into 250 millimeter intervals.
Step 2: Next, fill the bottle up with water.
Step 3: Then, place a piece of tubing into the bottle.
Step 4: Ask your friend for some help in placing the bottle into a half filled basin of water. Ensure it is placed in the sink in case there is an over spillage of water.
Step 5: After that, place the tubing in your mouth. Taking an ordinary breath, blow out as much water as you can.
Step 6: Record, in millimeters, how much water you have blown out of the bottle.
Step 7: Then, fill up the bottle again. This time take a deep breath and blow into the bottle.
Step 8: Record, in millimeters, how much water you have blown out of the bottle.
Step 9: Do 15 minutes exercise a day for two and a half weeks.
Step 10: Finally, repeat Steps 2-8 after two and a half weeks.
What We Have Learned:
- Two people from our class measured their lung capacity before and after 15 minutes of exercise over two and a half weeks
- The results showed that their lung capacity had increased after two and a half weeks
We also carried out our own research about the respiratory system. This included information about; Smoking and the Lungs, How the Respiratory Works with Other Systems in the Body and Asthma.
In fourth class we have been busy testing our heart rates. Before exercise we tested children’s heart rates using the heart rate monitor. After the exercise we tested them again to see if there was any change in their heart rates. The heart rate monitor told us how many times their heart beat per minute (bpm). Here are some of the results we collected.
Kalya Before exercise 96bpm
After exercise 120bpm
Oliver Before exercise 90bpm
After exercise 130bpm
Declan Before exercise 78bpm
After exercise 135bpm
Oscar Before exercise 150bpm
After exercise 200bpm
We found out that your heart rate changes after exercise. It beats faster. Oscar had a high heart rate before exercise and we know this was because he was nervous and excited about using the heart rate monitor. He was also doing a lot of talking at the beginning!!
For the next few weeks we are hoping to use the heart rate monitor before and after P.E every week.
Which should we use butter or margarine and why?
- First we conducted a survey of the butters and margarines used in Fifth class room 6.
Then we made a tally chart and bar chart displaying our findings.
- Then we identified the ingredients each of these contained. We made a stacked bar chart of these ingredients.
Some margarines contained 9 /10 ingredients including preservatives, colouring, Emulsifiers, acidity regulator
We were shocked to discover that Flora and Benecol contained the exact same ingredients as stock margarine even though they were over 4 times the price.
- Then we investigated which butter or margarine would go off first. Findings: –
a) Pure butter went mouldy after 10 days.
b) However, after 3 months none of the margarines have gone off.
- Finally we made pure butter by shaking double cream.
Try this at home. It is so tasty!
For this year’s Science Exhibition we combined sensory play, maths and science into one fun activity! We each took turns to find hidden objects in a tray filled with pasta and tested them to see if they were magnetic or non-magnetic. We sorted the objects into two sets and recorded our results on a data chart. We all had great fun using the horseshoe magnet and investigating what is attracted to it. Lorchán did a fantastic job presenting our work to parents in the hall.
We have been learning all about the heart in fourth class. Here are some interesting facts about the heart.
Did you know?
- The heart pumps blood to all parts of the body.
- The blood brings oxygen to the muscles.
- Heart rate increases with exercise so that more of the oxygen carried in the blood can reach the muscles.
- The fitter you are, the quicker your heart rate returns to normal.
- An adult’s heart rate is around 70 beats per minute, and a child’s is a bit higher.
- A mouse’s is about 500 beats per minute, and an elephant’s is about 25 beats per minute!
- Our hearts are pumping at a regular rate. This pumping can be felt by placing fingers across the pulse point at the wrist or the neck, and the rate can be counted.
- Your heart is about the same size as your fist, and weighs about the same amount as a lemon.
- Your heart is located in your chest, near your lungs, and to the left of the hard bone in the middle of your chest (the breastbone).
- Your heart is an organ made of muscle.
- The heart is an important organ in the body. It helps deliver oxygen and nutrients that are in the blood to all the other organs in the body.
We had great fun in fourth class today investigating friction. We tested a variety of different surfaces to see which had the most friction. We rolled a toy car down a slope and and then measured the distance it travelled on each surface.
We also created our own hovercrafts using a CD, a bottle lid and a balloon. It was great fun. We are looking forward to presenting our experiment at the science fair tomorrow.
