P7A created these beautiful eye drawings recently using soft drawing pencils to work on our sketching techniques. To add a bit of colour we used coloured pencils in the iris and drew something we were looking forward to.
We have been learning about reproduction and DNA in class. Today we carried out an experiment to extract the DNA from a strawberry. We discussed where extraction of DNA might be used to help in cloning, forensic crime investigation, studying genetic diseases and bacteria and viruses in the environment.
It took quite a few steps and we had to be very careful but we were so happy when we finally managed to lift the DNA extract out on a cocktail stick.
This week P7B have been applying their learning about the speed, distance, time triangle to real life scenarios.
We ran a sprint and a middle distance run in the playground and calculated our average speed. We then compared it with the world records for these distances. We couldn’t believe how fast Usain Bolt ran his 100m record!
We have also used the scale on an atlas to find the distance between countries and used this and the average speed of a plane to predict flight times. We used a bus timetable and the average speed of the bus to calculate the distance travelled. We built a ramp and raced different toy vehicles to calculate speed. We also looked at how time zones impact the way businesses work and worked out which country will celebrate new year first.
Some of our tips for P7A who will do some of these challenges soon are –
Read the task CAREFULLY
Follow the rule of the SDT triangle
The lines on the world map can help you with time zones
Make sure the angle of your ramp is the same on each go or it will affect your results
Use a ruler the find the scale on a map – we rounded to the nearest whole centimetre to make it a bit easier
