Hi
Your child answer is correct.Since clear plastic is a transparent material,light path is not blocked also by the transparent material and hence, the soccer ball's shadow is casted on the screen

Hi
This question is a bit tricky.Answer cannot be (4) as wooden pole is opaque.
Thus,answer could be only (3) as the light source is a distance away from the wooden pole.Therefore,the shadow becomes fainter.When light source is shone on the right side of an object,the shadow comes on the left side of the object.Same this concept when it applies when the light source is left side of the light source.The shadow would appear on the right side of the object.
cheers

Anyone has idea about the movement of cockroach?


Paul put some animals into 3 groups, X,Y,and Z, as shown in the table below
Group X: grasshopper, sparrow
Group Y: Bee, Bat
Group Z:Shhark, Turtle

In which group would you put the word \"cockroach\"? :?

Thanks!

my guess is group X because they share the same (3 stages) life cycle and bothof them can fly and hop

I would also choose X.

Hi
He should measure the temperature of the milo in the three containers.Yes,you are right.Because, the dependent variable is the temperature of the milo.
