This week we have begun our Forces and Motion unit of inquiry. Gravity and friction are the key ideas we have been investigating, and have been the focus of two hands-on technology challenges in our classroom.
In the first challenge we were required to make a ramp to certain specifications. We then predicted how far a marble would roll along the ground when let go from the top of the ramp.
After measuring the actual distance rolled and comparing with our estimates, we had some great discussions around our understanding of gravity and friction. It was most interesting hearing what everyone thought was in the centre of the Earth. Answers included "special stones", "rocks" and "black stuff". Some ideas there for further investigation.
The second challenge features in the video below.
As predicted by some of us, it certainly was a challenge working in groups of 4 or 5. Many people often have different ideas on what will work best in situations like this, so the designated 'team managers' had a busy job.
We agreed that some of the construction work wasn't pretty. But it was good to see everyone searching hard for materials that could serve a purpose (you may have noticed all of the random maths equipment and stationery items being used!).
A couple of groups managed to complete the task and others came very close. The most common challenge was the marble losing too much speed by crashing into walls. All groups realised that they needed to do what they could to maintain the marble's speed (provided by gravity), while keeping it on track to cross each piece of masking tape.
We will be reflecting on what we noticed during this challenge, while exploring more of the physical world around us over the coming weeks.
Good video like the music in the back ground
ReplyDeleteAmazing room 14!, I love how your marble tracks were layen out. I especially loved Big boys one because when Mr K did it in slow-mow, I was actually suprised that it worked.
ReplyDeleteOnce again I loved the marble tracks,
Great regards,
Reuben
As i was one of the managers it was hard making decisions for the team. But my team worked well together. For the first session we just talked about ideas and so we had a plan and we tested it in the next session and it didn't take that long for us to build and we made it go over all the pieces of tape as required. If i could do it again i don't know what i would change.
ReplyDeleteThis was a challenge for me because it was hard to get the marble to the end of the track.
ReplyDeleteThis was my challenge because it was hard getting the marble to get to the other end of the track. But I learnt from my mistakes and if there was a next time I think I would know what to do like with the designing.
ReplyDeleteThis was a challenge for me because it was hard to put the things together and it was hard to get past the finsh line.
ReplyDeleteIt was really challenging trying to actually get the marble and get the track going.
