In science, we have started our States of Matter unit. We began by learning about the different properties of matter including color, shape, size, state of matter, hardness and mass. We learned the definition of mass, which is the amount of matter (stuff) within a substance or object. We learned that the tool to measure mass is the balance which is measured in milligrams and grams. In groups, we built our own balances using a ruler, paper cups, and other materials and used gram cubes to measure the mass of different objects. The fourth graders discussed the difference between weight and mass including by watching a video of the differences between mass and weight which I'm including here! We also learned that on the moon there is a difference between weight as compared to here on Earth, but not in mass! We've had a very hands-on start to our fourth grade science year!
Enjoy the song - it is hard not to sing along!

Science - Invasive Species
Hi Parents,
Our class has been talking about natural balance in an ecosystem. We've experimented with the removal of an organism from a habitat and the disastrous results of removing just one organism. Last week we also learned about problems with adding an organism into a habitat. We read about how rats were accidently introduced to Hawaii and how people have tried to solve that problem by introducing another invasive species into the habitat to hunt the rats which led to even more disastrous results.
We watched two short clips about invasive species including this one about the threat of Asian carp to the Great Lakes.
The other video is about the threat of zebra mussels. Clink on the link about zebra mussels and scroll down to watch the video.
Please let me know if you have any information you'd love to share about invasive species with our science classes! We'd love to have you share your knowledge with our students!
