To get started, let’s create a chart to identify the best location to find each of these resources – diamonds, lumber and gold. Let’s start with diamonds. Did you know that diamonds are high in carbon? We can use this information to pick the best spot to find diamonds. Build a chart for each site (A, B, C, and D) by tapping the plot point represented by the percentage of carbon listed. Keep trying until the chart is completed.

Congratulations! Charting and graphing were really helpful. Wouldn’t you agree? Building a chart helped us pick the best locations for each resource. Using a graph allowed us to plot those locations and use coordinates to retrieve them. Be sure to write down this code word in your logbook.

Hi, I’m Ms. Whitney, a geologist. Have you ever been on an expedition? Well, you are going on one now, but we need to prepare by charting and graphing the resources that may be found at our excavation site. Tap next to begin this journey.

Great job! Now select the location from the chart that has the greatest amount of carbon.

Select the location from the chart that has the greatest amount of carbon.

You did it! By identifying the location with the greatest amount of carbon, we’re that much closer to finding diamonds. Tap the next button to continue.

clay

Lumber is a very important resource. We must find the location with the lowest concentration of clay resulting in the greatest amount of tree growth. There are four locations to choose from that contain varying concentrations of clay. Look at each one and build a chart by tapping the plot point represented by the percentage of clay levels. Keep trying until the chart is completed.

Select the location from the chart that has the lowest concentration of clay.

Now select the location from the chart that has the lowest concentration of clay.

You did it! By identifying the location with the lowest concentration of clay, we’ve got the best shot at identifying a healthy lumber source. Tap the next button to continue.

Gold! It’s valued worldwide. We want to look for gold at a location that has optimal purity. For our purposes, 24K gold is too soft so let’s find 18K gold which has 75% purity. Look at each purity level and build a chart by tapping the plot point represented by the percentage. Keep trying until the chart is completed.

Great job! Now pick a location on the chart which offers a purity level closest to 75%.

Pick a location on the chart which offers a purity level closest to 75%.

That’s not the location that’s closest to 75% purity. Tap return to try again.

You did it! By identifying the location with a purity level closest to 75% we’re on our way to discovering a valuable vein of gold. Tap the next button to continue.

Now that we’ve identified our three locations for diamonds, lumber and gold, use this graph to identify the coordinates for each site. To do this, tap the arrows to enter the correct X and Y coordinates.

Travel to…

Let’s jump in the jeep and go collect our resources. Starting from the star on the map, enter the coordinates that describe the distance you need to travel in each direction to get to the diamond site. Then tap Go!

Those coordinates didn’t get us to the site. Think about the distance you have to travel. For instance, if you need to go left, X will be a negative value. If you need to go up, Y will be a positive value. Tap the return button to try again.

You did it! We have successfully picked up our diamonds. Tap next to collect our lumber.

Go!

We’re there! Let’s load up the lumber. Tap next to mine some gold!

Those coordinates didn’t get us to the site. Think about the distance you have to travel. For instance, if you need to go right, X will be a positive value. If you need to go up, Y will be a positive value. Tap the return button to try again.

Starting from the diamond site, enter the coordinates that will take us to the lumber. Then tap Go!

We found the gold! Time to mine it and head home. Tap next to continue.

Those coordinates didn’t get us to the site. Think about the distance you have to travel. For instance, if you need to go left, X will be a negative value. If you need to go down, Y will be a negative value. Tap the return button to try again.

Starting from the lumber site, enter the coordinates that will take us to find gold. Then tap Go!
