🫀Investigating our heart rate🫀

Crew Gray have been investigating to determine if exercise directly impacts our heart rate. We conducted a controlled experiment measuring our heart rate at resting, low intensity exercise and high intensity. We did this by recording our pulse before and after each activity, before recording our findings, which we are now going to use to write our investigation report.

Learning all about blood

In Crew Gray, we have been discovering all about blood and what it is made of! During an exciting hands-on lesson, we explored the four main components of blood and uncovered the important job each one has to keep our bodies healthy.

We used water mixed with yellow food colouring to represent the plasma, which gave the liquid a realistic look. Marshmallows were used to show the white blood cells, which help the body fight infections. Cheerios represented the red blood cells, which carry oxygen throughout the body and give blood its red colour. Small pieces were also added to represent platelets, which help blood clot when we get a cut. As we carefully added each part to create our own “blood model”, we were amazed to see how these components work together to help our bodies function every day.

Finding Fractions!

Crew Ramsay got stuck into some Concrete Maths to conceptually understand fractions of an amount. We divided an amount into 4 equal parts to ‘see’ the quarters. We then found 3/4 of the amount by adding 3 of the equal parts together. Here we are getting stuck into some part, part whole activities.
