Get ready to celebrate National Science Literacy Week on September 18, 2019.
On that day our science class will participate in the Science Reading Activity

Science Literacy Week runs from September 16-22, 2019.

Welcome Back to an exciting year of learning!

Parasitic Plants – how plants borrow useful genes from other plants…

Observe the fur colour of the baby foxes.

How is the fur colour of the baby foxes the same as the parent foxes?  

How is the fur colour of the baby foxes different?  

What type of simple pattern of inheritance does this represent (dominance, recessive, incomplete or codominance)?

Notes:

DNA to RNA to mRNA to tRNA

How do rockets work?
Rockets don’t work by “pushing against the air,” since they also function in the vacuum of space. Instead, rockets take advantage of momentum, or how much power a moving object has.

If no outside forces act on a group of objects, the group’s combined momentum must stay constant over time. Imagine yourself standing on a skateboard with a basketball in your hands. If you throw the basketball in one direction, you and the skateboard will roll in the opposite direction to conserve momentum. The faster you throw the ball, the faster you roll backward.

Rockets work by expelling hot exhaust that acts in the same way as the basketball. The exhaust’s gas molecules don’t weigh much individually, but they exit the rocket’s nozzle very fast, giving them a lot of momentum. As a result, the rocket moves in the opposite direction of the exhaust with the same total oomph.
