This week in G9 Coordinated Science Biology the students used a cartoon strip template to storyboard an animation explaining how the immune system protects us from pathogens (disease causing microorganisms). They were inspired by a video that turned the body’s defense against disease into a cinematic role playing game.
They used their MacBook’s and camera phones to record a mixture of stop motion animation and video. All of the students produced amazing videos that will be used by other coordinated science classes to aid revision.
This week in G9 Coordinated Science the students used a number of everyday science objects such as a toy car, a plant, a “factory box”, crude oil, soil, animal organ models and a bottle containing carbon dioxide to model the carbon cycle. The students worked in small groups and made links to how each object is linked to each other by the recycling of carbon. They were then able to recall the word and balanced symbol equation for photosynthesis and respiration from previous topics studied this year.
This week in G9 Biology we started the second topic on Biological molecules, Enzymes and Animal Nutrition. The first biological molecule we discussed was Deoxyribose nucleic acid (DNA). This is the ultimate information storage and retrieval molecule. DNA has the blueprint for making proteins and ultimately almost all life on Earth. We discussed the structure of DNA and the importance of complementary base pairing (A with T and C with G) by using pipe cleaners as a model. Finally we referred back to Topic 1 as we discussed how DNA barcoding is based on analyzing the sequence of DNA bases to identify and classify organisms based on how similar their sequences are.
Thanks for your amazing creativity and effort.
Although we did not extract a lot of DNA today, you can try this experiment again at home.
In this weeks Double Helix club we built a scale model of the solar system. We used the S1 and S2 hallway to show the relative distance between planets.
Use this website to find out your weight on other planets in the solar system.
weight (N) = gravitational field strength ( on Earth this is 9.81) x mass (kg).
