Scientific Tools

…a triple beam balance -measures mass

Don't forgot to write you length measurements in cm today!

Engagement: Remember the Lego activity that we did where we rolled ourLego cars down the ramps? Well our little Lego-car driver’sprotested that this activity was unsafe for them since the cars didnot have any brakes.

So they asked if we could install some brakes on the cars. Thatis what we will do today. Start thinking about how you couldconstruct some kind of braking device on your Lego cars.

Uphill Struggle Experiment


Materials:1 lab journal sheet per student ( I will pass these out) 1 car with brake illustration/handout (is orange colored)11 work stations1 triple-beam balance per work station4 rampsNumerous meter sticks and rulers 1 Lego kit per work station1 weight per Lego kit

Activity: Construct a 4-wheel Lego car with a brake per the provided

illustration (see the orange handout) Measure the mass of the black weight (in grams) Measure the mass of the car without the weight (in grams) Add the mass of the car and the weight together (in grams) Confirm that the car will roll forward Turn the car around backwards, and place it at the top of the

ramp. Observe to see if the car rolls backwards or not. If it rolls backwards, measure how far it rolls before it stops in

(in centimeters) Complete the journal work sheet (see other image on screen)

Start with your prediction
