Research Time

Students are spending the afternoon working on their research and experimentation. Some groups discovered that science is not easy... while others were excited to see their hypotheses confirmed. All the groups are learning that two important values: 1) collaborating with group members to make decisions can be a challenge and 2) designing experiments which yield valid data is hard. 

Way to go LC and Trinity... the groups are doing great. - Mr. Heintz

Group members prepare for data collection using ant aggression scale.

Jack Ryan extracting his queen for isolation.

Observations: with the queen removed from the colony, the other ants show signs of aggression.

Group members put their positive control to test. With a few adjustments, it works well.

The physical barrier does a great job preventing the ants from going down the path. 2min and 35secs later, the ants found a way around their barrier and thus set their positive control.

Another group watches their positive control to see if the ants will eat the gmelina leaves.

Gmelina leaves are being cut by the ants (notice the half moon cuts in the bottom right corner of the leaf). Positive control is ready.
