Science fair projects assigned!

Today we made final observations about the speeds of the 4 boats. Hopefully you all made the connection between the steepness of the graph line and the speed of the boat on a distance V time graph.

The steeper the line the faster the object  moves.

The second half of class was spent in the computer lab getting ideas for the science fair. Please look at my Science Fair tab on this website for ideas.

This avalanche moved at the slow speed of 15km/hr. What does this tell you about the slope of the mountain?

Discussion and boat speeds

After talking through the variables that were not controlled in the speed investigation we looked at another way to describe motion using graphs.

The graph on the right is a complex description of 4 different boats.

We concluded that

" the steeper the graph line the faster the object is moving"

Graphing and conclusion

Today you made your graph. This was complicated for some of you as you wanted to graph the inclined plane height versus the time however the question asked about speed so you first had to calculate the speeds then make the graph!
Here is a good graphing example.
