This week we further looked at gravity by finishing up our Acceleration Due to Gravity Lab. We then did a small activity that illustrated air resistance. Next week we'll be studying car collisions and the final full week we'll set up for our egg drop. Fun times ahead!
This week we attempted to verify that the acceleration of an object due to gravity is really 9.8 m/s^2. We found that there were limitations in the accuracy of our measurements due to the reaction time of our starting and stopping of the timers. All in all it was interesting. We'll finish those labs up on Tuesday and then talk about air resistance.
This week we took a look at some simple machines. Tuesday we saw the effect of adding more and more pulleys to a system. It's amazing the mechanical advantage you can achieve by sacrificing distance traveled. Thursday we celebrated Sage Earth Day by building catapults which take advantage of a lever, another simple machine.
Happy Tax Week! We've been working our way through two lab activities this week in order to explore the concept of potential energy and see how force and pressure relate. Feel free to take a look at the two labs below for more information!
Don't forget, ISATs start next week. Eighth graders will be taking them on Monday and Wednesday so they shouldn't interfere with science class.
Have a great weekend!
Welcome to April! Flowers are blooming and attention spans are shortening. It's important to remain diligent to your classes as we hone in on the final months of school! Next year high school starts and we need to head into summer with the expectation that we be constantly learning while in class (and you're welcome to learn outside of class as well).
The past two weeks we've taken a look at energy beginning with the Law of Conservation of Energy where we analyzed a Rube Goldberg device for all the different changes in forms of energy. This week we learned about force, culminating in the steam cannon lab (lots of great slow motion video was taken).
We had a great week that ended with a little Comedy of Errors from the Idaho Shakespeare Festival. I was very thankful that it was a comedy and not a tragedy.
We've been looking at forms of energy. Monday we started a foldable (after finishing up our windmill lab) and Wednesday we finished it. We'll be talking about energy changing forms next week and explore the exciting world of pendulums!
An exciting week as we designed and built wind turbine blades! We then used these blades in an inquiry project exploring one variable such as angle, size, number, material, and whatever else students wanted to try out. We'll share our results Tuesday via posters created in class and analyze the data to come up with what we think the best setup is for a wind turbine. Fun!
Hello Earthlings. This week we took a look at how the United States generates its electricity in order to build a little background for our Windmill Generator Lab. We then started to design windmill blades from a scientific standpoint with each group exploring one variable. We'll have a competition in the end to see who can generate the most electricity.
Daily Presentation Slides
Virtual Windmill Lab
This week we presented our findings regarding our Electromagnetic Nail Lab. We created posters and then asked scientific questions of other students' posters.
This weeks project was to build an electromagnet using a nail, battery, and copper wire. Once built students tested one variable to see it's effect on a compass needle. Most groups got great results and made some beautiful graphs. Instructions for the lab are embedded in the daily presentation slides which are linked below.
We'll have our first summative assessment on Tuesday. Students will present their findings and classmates must analyze their data and come up with further research questions that could be explored. We will be covering this extensively before the actual assignment on Tuesday, so don't panic if it doesn't make sense.
